Objective To compare the early compl ications of carotid stenting (CAS) and carotid endarterectomy (CEA) in treatment of carotid artery stenosis. Methods Between January 2005 and December 2007, 63 patients with carotid artery stenosis were treated with CEA in 36 cases (CEA group) and with CAS in 27 cases (CAS group). There were 42 males and 21 females with an average age of 67.5 years (range, 52-79 years). The locations were the left side in 28 cases and the rightside in 35 cases. The carotid stenosis was 60%-95% (mean, 79%). The major cl inical symptoms were stroke and transient ischemic attack. The cranial CT showed old cerebral infarction in 24 cases, lacunar infarction in 22 cases, and no obvious abnormal change in 17 cases. The encephalon, heart, and local compl ications were compared between 2 groups within 7 days after operation. Results In CEA group, encephalon compl ications occurred in 3 cases (8.3%), heart compl ications in 2 cases (5.6%), and local compl ications in 5 cases (13.9%); while in CAS group, encephalon compl ications occurred in 8 cases (29.6%), heart compl ications in 1 case (3.7%), and local compl ications in 3 cases (11.1%). The encephalon compl ication ratio of CAS group was significantly higher than that of CEA group (χ2=4.855, P=0.028); and there was no significant difference in other compl ications ratios between 2 groups (P gt; 0.05). Conclusion CEA is the first choice to treat carotid artery stenosis.
【Abstract】 Objective To explore the cause of the perioprative period compl ication of scandinavian total anklereplacement(STAR) and to summarize the experience in the treatment and prevention. Methods From March 1999 toNovember 2006, 35 patients were given total ankle replacement(TAR) with STAR system. There were 19 males and 16 femaleswith an average age of 50.5 years (27 to 68 years), including 12 cases of posttraumatic arthritis, 8 cases of osteoarthritis and 15cases of rheumatoid arthritis. All patients had pain of ankle joint, swell ing and l imitation of joint motion. The disease coursewas 9-64 months. The curative effect was estimated by Kofoed total ankle scoring system. The mean preoperative ankle scorewas 29(6-48); the mean pain score was 18.3(0-35); the mean function score was 11.7(6-18); and the mean activity score was9.2(3-12). The type of all compl ications were record, and its cause, prevetion and treatment were analyszed. Results Thirtythreepatients achieved heal ing by first intention, 2 achieved delayed union because of infection. Twenty-eight patients werefollowed up 3-80 months (mean 43.5 months). Medial malleolus fracture occurred in 2 cases, unstable ankle joint introversion in2 cases, l imitation of ankle dorsiextension in 1 case and 1 case had hypoesthesia at intermediate dorsal skin of foot and 3rd-5thmetatarsal skin without obvious dysfunction; all were treated with symptomatic medication. The postoperative mean ankle scorewas 85.5 (58-95); the mean pain score was 48.3(35-50); the mean function score was 20.7(18-30); the mean activity score was17.2(16-20). There were statistically significant differences when compared with preoperative score(P lt; 0.01). The cl inical resultswere excellent in 16 patients, good in 9 patients and fair in 3 patients. The X-ray films showed no loosening and subsidence ofprosthesis. Conclusion Although STAR can retain the functions of the operated joint, it has its special compl ications. It isimportant to obey operation principle with proficient operative technique, to strictly control surgical indication and to intensifyperioperative period treatment so as to decrease the compl ications.
Objective To investigate the donor-site compl ications of the anterolateral thigh flap and its influencing factors. Methods Between July 1988 and July 2007, 427 patients were treated with anterolateral thigh flap. Among them, 33 patients had postoperative donor-site compl ications and their cl inical data were analyzed retrospectively. There were 21 malesand 12 females aged 14-47 years old (average 32.7 years old). The size of the wound defect ranged from 16 cm × 7 cm to 28 cm × 13 cm. The area of the flap harvested during operation ranged from 16 cm × 7 cm to 30 cm × 13 cm. The donor sites were treated by direct suture in 7 cases; free spl it-thickness skin graft in 23 cases, and reverse superficial epigastric artery flap repair in 3 cases. The size of graft in the donor site ranged from 10 cm × 5 cm to 18 cm × 8 cm. The occurrence of short-term (within 4 weeks) and long-term (over 6 months) compl ications were analyzed. Results All patients were followed up for 8-54 months (average 21 months). There were 26 patients (78.8%) with short-term and long-term compl ications and 7 patients (21.2%) with long-term compl ications. The short-term compl ications included skin graft necrosis in 23 cases (69.7%), wound infection in 17 cases (51.5%), and muscle necrosis in 2 cases (6.1%). The long-term compl ications included non-heal ing wounds in 21 cases (63.6%), serious scar in 28 cases (84.8%), discomfort in 25 cases (75.8%), and dysfunction of the quadriceps femoris in 16 cases (48.5%). Conclusion The occurrence of anterolateral thigh flap donor-site compl ications is related to the anatomical structure of the anterolateral thigh region, the surgical procedure, and the patient’s physique.
Objective To investigate the etiology, diagnosis, and treatment of acute carpal tunnel syndrome (ACTS) after reduction of Colles’ fracture. Methods Between December 2006 and June 2010, 22 patients with ACTS after reduction of Colles’ fracture were treated with expectant treatment and surgical treatment. There were 9 males and 13 females with an average age of 46.2 years (range, 23-60 years). Fractures were caused by traffic accident in 9 cases, fall ing in 8 cases, fall ing from height in 2 cases, hitting in 2 cases, and crushing in 1 case. The mechanism of fracture was direct violence in 3 cases and indirect violence in 19 cases. According to Gartland ＆ Werley classification, there were 2 cases of type I, 5 cases of type II, 14 cases of type III, and 1 case of type IV. Closed reduction was performed in 19 cases and open reduction and internal fixation (ORIF) in 3 cases. The average symptom time of ACTS after reduction of Colles’ fracture was 11.6 hours (range, 1 hour 30 minutes to 48 hours) in patients undergoing closed reduction and was 24 hours in 1 patient and 2 weeks in 2 patients undergoing ORIF. Expectant treatment was performed first, the forearms were put in neutral position in closed reduction cases; if there was no rel ief of ACTS symptom 1 week later, the mixture of 1 mL glucocorticosteroid and 1 mL 2% l idocaine was injected into carpal tunnel once a week for 2 weeks. The mixture was injected into carpal tunnel directly once a week for 2 weeks in ORIF cases. In the patients who failed to expectant treatments, ORIF was performed. Results In 7 cases of type III that failed expectant treatment, ACTS symptoms were rel ief completely after ORIF. All the 22 patients were followed up 12 months on average (range, 8-18 months). The average time of complete disappearance of median nerve compression symptom was 11 days (range, 2-25 days). All the patients had normal finger motion, sensation, and opposition of thumb with no sensation of anaesthesia and pinprick. The results of Tinel test, Phalen test, and Reverse Phalen test were all negative. The X-ray film showed good fracture reduction and heal ing with an average heal ing time of 6 weeks (range, 3-14 weeks). According to GU Yudong’s criteria for functionalassessment, the results were excellent in 18 cases and good in 4 cases; the excellent and good rate was 100%. Conclusion Malposition, displacement of fracture fragments, and ulnar deviation of the wrist after plaster immobil ization are the mostimportant risk factors for ACTS. Expectant treatments are recommended in patients with Colles’ fracture of types I, II, and IV,but surgical treatment is the first choice for Colles’ fracture of type III.
Objective To introduce a modified penile elongation method and observe its postoperative compl ications. Methods From January 1993 to December 2007, 130 patients with congenital short and small penis were divided into 2 groups: the routine group and the modified group, with 65 patients in each group. In the routine group, the patients were 18-55 years old (39.6 on average), and the penile length during erection was (4.9 ± 1.4) cm. In the modified group, the patients were 20-56 years old (35.4 on average), and the penile length during erection was (5.0 ± 1.5) cm. There was no significant difference between the two groups (P gt; 0.05). On the basis of scrotal flap which was transferred to cover the prolonged cavernous body of penis, the “+” shaped incision at the root of the penis was made in the routine group, and theincision was shifted upward by 1.5 cm in the modified group. And V-Y incision was made for the penises with more than 4 cm prolonged length. In order to compare the conditions in the two groups, no physical therapy was appl ied in 30 days after the operation. Results All the 130 patients’ incisions obtainedt heal ing by the firs intention, and all flaps survived successfully. Postoperative hydrophallus appeared differently between both groups. In the routine group, obvious hydrophallus appeared on the 3rd day after the operation and lasted for (15.11 ± 2.71) days, with 3 cases (4.62%) suffering from refractory hydrophallus. In the modified group, hydrophallus appeared on the 3rd day after the operation and lasted for (6.65 ± 0.29) days without any refractory hydrophallus. There was significant difference between the two groups in the duration of hydrophallus (P lt; 0.05). All patients were followed up for 6-8 months. After the operation, the shape and function of the penis were found good. The prolonged length was (4.9 ± 1.4) cm in the routine group and (5.0 ± 1.5) cm in the modified group. There was no significant difference between the two groups (P gt; 0.05). The satisfaction rate (according to the patients’ self-rating) was 95% and 98% in the routine group and the modified group, respectively. Conclusion The method using the scrotal flap transferred to cover the prolonged cavernous body of the penis is safe and of low compl ication rate. The modified method is more effective to abate postoperative hydrophallus.
Objective To study the prevention and management of early compl ications associated with anterior cervical spinal surgery. Methods From November 1998 to December 2006, 363 cases were treated with anterior cervicalsurgery, including 268 males and 95 females aged 17-79 years．In these cases, 224 suffered from cervical spondylosis, 39 from cervical disc herniation, 87 from cervical trauma, 9 from cervical tumor and 4 from cervical tuberculosis. Forty-eight cases with anterior cervical surgery were fused by autogenous il iac bones, 132 cases with anterior cervical surgery were fused by autogenous il iac bones and anterior cervical spine locking plates, and 183 cases with anterior cervical surgery were fused by titanium mesh cage and anterior cervical spine locking plates. Results A total of 282 cases were followed up for 3 months to 5 years with the average of 1 year and 11 months. Twenty-three compl ications associated with surgery were found, with an incidence of 8.16%. Three cases of transient superior laryngeal nerve palsy recovered within 3-7 days after the restriction of l iquid diet and fluid replacement. Two cases of recurrent laryngeal nerve palsy recovered by 3-month pronunciation practice. One case of spinal cord injury was treated with medicine for dehydration and anti-inflammation, and was restored to preoperative muscle power of inferior extremity after 6 months. Two cases of CSF leakage were cured with moderate local compression and meticulous water-tight wound closure. Among the 10 patients with compl ications of internal fixation, one suffering mild dysphagia was reoperated, while the others were treated with cephal-cervico-thorax plaster external fixation and recovered with sol id fusion within 3-18 months. Among the 4 cases with cervical hematoma, 1 died of wrong rescue procedures and 1 was infected. Conclusion Adequate preoperative preparation, thorough understanding of anatomy related to the anterior approach and skilled surgical technique are essential for preventing the early postoperative compl ications of anterior cervical spinal surgery．
Objective To compare the therapeutic effect of new “One-Stitch” ureterovesical anastomosis to that of the classic Lich-Gregoir method. Methods From January 2002 to December 2004, 445 patients suffering from uremia due to chronic nephritis were treated with renal transplantation. Among them, 121 patients were operated with our new modified ureteroneocystostomy technique (the new One-Stitch group), and 324 patients were operated with Lich-Gregoir technique (the Lich-Gregoir group). In the new One-Stitch group, there were 79 males and 42 females, aged 20-62 years (35.7 years on average). The course of the disease was 2-11 years (2.7 years on average). In the Lich-Gregoir group, there were 211 males and 113 females, aged 19-65 years (33.9 years on average). The disease course was 1-14 years (2.3 years on average). There was no significant difference between the two groups in age, proportion of genders, primary diseases and course of the disease (P gt; 0.05). The operative time, the ureteral compl ications and non-ureteral compl ications were compared between the two groups after the renal transplantation. Results The operative time for the new One-Stitch and Lich-Gregoir techniques was (8.7 ± 1.1) minutes and (22.4 ± 5.1) minutes, indicating the difference was significant (P lt; 0.05). All recipients were followed up for 3-5 years. In the new One-Stitch group, there were 5 patients with leakage of urine, 15 with gross hematuria, 4 with ureteral obstruction and 28 with urinary system infection. Symptomatic vesicoureteral reflux and stone formation were not observed in this group. In the Lich-Gregoir group, there were 17 patients with leakage of urine, 12 with gross hematuria, 13 with ureteral obstruction, 86 with urinary system infection, 6 with symptomatic vesicoureteral reflux and 2 with stones. In the new One-Stitch group, the incidence rate of compl ications of gross hematuria was 12.4%, which was significantly different from 3.7% in the Lich-Gregoir group (P lt; 0.05). The incidence rates of ureteral compl ications in the Lich-Gregoir and the new One-Stitch groups were 19.8% and 15.4%, respectively. The difference was not significant (P gt; 0.05). There was no significant difference between the two groupsin incidence rate of urinary system infection, delayed recovery of kidney function after kidney transplantation and rejectionreaction (P gt; 0.05). Conclusion The new One-Stitch group has no significant difference in ureteral compl ications ompared with the Lich-Gregoir group, and has become a preferential ureterovesical reimplantation technique because of its simple and has convenient operation.
Objective To analyze the causes and managing methods of long bone fracture nonunion after allogeneic bone transplantation. Methods From December 1995 to December 2000, 43 cases of postoperative nonunion of long bone fracture were treated. These cases included 31 males and 12 females at the age of 19-57 years (40 years on average). The locations were femur in 11 cases, tibia in 21 cases, humerus in 8 cases and forearm in 3 cases. Bone nonunionafter allogeneic bone transplantation was caused by extensive soft tissue contusion and poor cover around bone fractue site in 6 cases, by incomplete debridement in 8 cases of osteomyel itis (including 6 without continual lavage and 4 only skin flap transfer), by secondary infection of wounds in 3 cases, by severe primary injury or secondary scar covering bone in 12 cases, instable internal fixation in 7 cases, and by earl ier weight bearing in 7 cases. Accroding to Weber classification, there were 4 cases of hypertrophic type and 39 cases of atrophic type. Basing on the type of nonunion, the methods such as refixation, bone retransplantation and transferring tissue flap were chosen to manage the cases. Results Incision healed by first intention in 37 cases, superficial infection occurred and cured after 2 weeks of dressing change in 5 cases, and sinus formed and cured after 2 months of dressing change and drainage in 1 case. All transferring tissue flap survived, and partial necrosis occurred at flap edge in 4 cases and cured after dressing change. All patients were followed up for 38-91 months with an average of 54.6 months. All the nonunion cases achieved bone union 5-11 months with an average of 7.6 months. But low extreme shorten monstrosity occured in 4 cases, malunion in 2 cases, functional l imitation near joints in 7 cases, and rotational l imitation of forearm in 1 case. Conclusion Fracture nonunion after allogeneic bone transplantation mainly shows atrophic type with overall or partial absorption of the allograft bone. The preconditions to guarantee fracture nonunion heal ing include stabil ity of fracture fixation, using transferring tissue flaps, controll ing infection, and adequate bone transplantion.
Objective To observe the complication after embolizing the bilateral internal il iac arteries and the median sacral artery of dogs by different combinations and embolization levels with gelfoam particle, and to provide a reference for safety appl ication of gelfoam in cl inic. Methods Sixteen common grade adult healthy dogs (weighing 10-13 kg, 14 males and 2females) were randomly divided into 5 groups. Under the monitoring of digital subtraction angiography (DSA), the embolization was performed with gelfoam particle (diameter, 50-150 μm) in bilateral internal il iac arteries and the main branch of the median sacral artery (group A, n=3), in bilateral internal il iac arteries and the first branch of the median sacral artery (group B, n=3), in the main branch of bilateral internal il iac arteries (group C, n=3), in the unilateral internal il iac artery and the main branch of the median sacral artery (group D, n=4), and in the main branch of unilateral internal il iac artery (group E, n=3). Under the DSA, the anatomic relationships of the abdominal aorta, bilateral external il iac arteries, bilateral internal il iac arteries, and median sacral artery were observed before embol ization. The survival dogs were observed and the specimens of bladder, rectum, sciatic nerve, and gluteal muscles were harvested for the general and histological observations at 3 days after embolization. Results In dogs, there was no common il iac artery; bilateral external il iac arteries originated from the abdominal aorta and the starting of the median sacral artery had variation. Seven dogs (3 in group A, 3 in group C, and 1 in group D) died within 2 days after embolization, and the others survived to the end of the experiment. In the dead dogs of groups A, C, and D, the darkening and necrosis of the rectum were observed; the bladder presented lamellar obfuscation and focal hemorrhage and edema; and the median urinary volume in bladder was 270.6 mL. In survival dogs, no obvious change was observed in the rectum; the bladder only manifested l ight edema; and the median urinary volume in bladder was 137.0, 220.5, and 28.0 mL, respectively in groups B, D, and E.The rectum and bladder of dead dogs in groups A, C, and D manifested the disrupted cells, generous inflammatory cells infiltration, and desquamation of epithel ial cells; the rectum and bladder of survival dogs in groups B, D, and E manifested l ight inflammatory cells infiltration and edema; the embol ized artery mainly focused on the arterioles whose diameter was 100-200 μm. The sciatic nerve and gluteal muscles of each group had no obvious change except for l ight edema. Conclusion When the internal il iac artery and median sacral artery are embol ized with gelfoam particle with a diameter of 50-150 μm, to ensure the safeness of pelvic organs, the embol ized artery can not exceed the first branch when the 3 arteries are embol ized at the same time, or reserve at least unilateral internal il iac artery when embol ized to the trunk , or it will result in pelvic organ necrosis and perforation.
Objective To review and investigate the compl ication and the treatment in Nuss procedure for correction of pectus excavatum. Methods From September 2005 to March 2009, 221 patients with pectus excavatum were treated withNuss procedure, including 189 males and 32 females and aging 2 years old and 10 months to 25 years old (median 8 years and 7 months old). Of 18 patients with recurrent pectus excavatum, 12 patients underwent a Ravitch procedure and the recurrence time of the depression after the first operation was less than 1 year in 2 patients, 1-3 years in 3, 3-5 years in 5, and over 5 years in 2; 6 patients underwent a stemotumover operation and the recurrence time of the depression after the first operation was less than 1 year in 2 patients, 1-3 years in 1 and 3-5 years in 3. The other 203 patients had a primary Nuss procedure, and the course of disease was from 18 months to 24 years. The preoperative CT scan showed the Haller index was 4.36 ± 1.34. Results The operation in all the patients were performed successfully without compl ications of death, massive hemorrhage and intrathoracic organ injury. The time of operation was 25-80 minutes (mean 40 minutes). The bleeding volume during procedure was 5-25 mL, with an average of 10 mL. Local allergy occurred in 3 cases after 7-10 months of operation, wound reject reaction in 2 cases after 3 and 11 months respectively, and effusion in 3 cases after 6-10 months; incision healed after dressing change. Incision healed primarly in the other patients. Pneumothorax occurred in 3 cases when the operation finished and in 7 cases after 2-4 days, pleural effusion in 4 cases after 3-5 days of operation, Nuss plate displacement in 2 cases after 3 days and 9 months, respectively. The patients having compl ication recovered well after treatment. The compl ication rate was about 8.72% (17/195). The followupperiod was 2-37 months for 195 patients. The postoperative Haller index was 2.52 ± 0.32 after 3 months of operation, showing statistically significant difference when compared with that before operation (P lt; 0.05). Conclusion Nuss procedure with non-thoracoscopic assistance for correction of pectus excavatum is safe because of less trauma and compl ication.
