目的探讨毒品注射所致感染性假性动脉瘤的特点及治疗方法与临床疗效。方法回顾性分析我院血管外科2009年1月至2010年6月期间收治的13例感染性假性动脉瘤吸毒患者的临床资料，采用切除瘤体及周围炎性组织、瘤腔清创及动脉结扎或人工血管置换术，观察移植效果及并发症发生情况。结果13例手术均获成功，无一例发生肢体坏死； 伤口一期愈合5例，二期愈合8例； 7例发生程度不等的淋巴瘘。随访2～12个月（平均7个月），其中1例术后2个月瘤腔下端感染形成脓肿伴出血，行切开引流痊愈； 2例术后4个月人造血管感染行人造血管摘除，切口换药痊愈； 有2例左肘部假性肱动脉瘤直接行血管结扎，未用人工血管移植； 余8例复查B超显示移植血管通畅，无血栓形成。结论彻底清创、血管移植、控制感染是治疗感染性假性动脉瘤的有效方法。
Objective To discuss the clinical application value of CT angiography (CTA) in traumatic pelvic artery pseudoaneurysm and dissecting aneurysm. Methods A total of 8 patients including 7 with traumatic pelvic artery pseudoaneurysm and 1 with dissecting aneurysm diagnosed by CTA in Suining Central Hospital from August 2012 to January 2016 were enrolled in this study, in whom 6 patients with traumatic pseudoaneurysm treated with embolotherapy were confirmed by digital subtraction angiography. Image post-processing techniques of CTA including curve planar reformation, multiplanar reconstruction and volume rendering were used. Results In the seven patients diagnosed as solitary traumatic pelvic artery pseudoaneurysm by CTA, 3 had superior gluteal artery pseudoaneurysm, 2 had inferior gluteal artery pseudoaneurysm, and 2 had external iliac artery pseudoaneurysm. The 7 pseudoaneurysms were pouch-shaped with the short diameters ranged from 9 to 64 mm and the long diameters ranged from 11 to 78 mm. Six locations of artery laceration were displayed clearly, thereinto 1 case was combined with arteriovenous fistula. In addition, a vessel occlusion caused by the limitation of right external iliac artery dissecting aneurysm and the thrombosis in left side of the external iliac artery was found in 1 case. Conclusions As a non-invasive diagnostic technique, CTA can accurately diagnose traumatic pelvic artery pseudoaneurysm and dissecting aneurysm, clearly display the location relationship of pseudoaneurysm and its parent artery, and find whether arteriovenous fistula exists. Beyond that, the true and false lumen of dissecting aneurysm can be precisely identified by this technique. CTA can provide important image information for formulating individual treatment plan.

Objective To compare the effectiveness, complications, and follow-up results between endovascular recanalization (EVR) and open surgical revascularization (OSR) in the treatment of peripheral pseudoaneurysm, so as to provide a reference for choosing a appropriate surgical procedure. Methods Clinical data of 62 cases of peripheral pseudoaneurysm between January 2001 and January 2012 were analyzed retrospectively. EVR was performed in 28 patients (EVR group) and OSR in 34 patients (OSR group). There was no significant difference in gender, age, cause of injury, tumor location, and diameter of tumor between 2 groups (P gt; 0.05). Results The operation time, blood loss, ICU monitoring time, and hospitalization time in EVR group were significantly shorter than those in OSR group (P lt; 0.05). In OSR group, 12 cases (35.29%) had early postoperative complications, including 2 deaths due to acute respiratory distress syndrome, 5 cases of pulmonary infection, 3 cases of wound infection, and 2 cases of deep vein thrombosis; in EVR group, 2 cases (7.14%) had early postoperative complications, including 1 case of hematoma at puncture site and 1 case of thrombosis in stent. There was significant difference in early postoperative complication incidence between 2 groups (χ2=6.691, P=0.008). The patients were followed up 12-39 months (mean, 26 months). In OSR and EVR groups after operation, the patency rates of the reconstructed vessels were 96.88% (31/32) and 92.86% (26/28) respectively at 12 months, showing no significant difference (χ2=0.014, P=0.905); the patency rates were 89.29% (25/28) and 84.00% (21/25) respectively at 24 months, showing no significant difference (χ2=0.322, P=0.570). Conclusion Compared with OSR, EVR is a minimally invasive, safe, and effective therapy for peripheral pseudoaneurysm with the advantages of less bleeding, shorter hospitalization time, and less complications. Long-term effectiveness still needs further observation, and patients have to take antiplatelet drugs for long time after EVR.
ObjectiveTo explore clinical manifestation, diagnosis and treatment of IgG4 sclerosing cholangitis developed postoperative gastroduodenal hemorrhage, so as to improve awareness and treatment of this disease. MethodThe clinical data of a case of IgG4 sclerosing cholangitis misdiagnosed as the hilar cholangiocarcinoma which developed postoperative gastrointestinal hemorrhage in this hospital were analyzed retrospectively. ResultsThis patient was misdiagnosed as the hilar cholangiocarcinoma and accepted the radical resection, while the postoperative pathology proved to be the IgG4 sclerosing cholangitis. One month later, the patient developed the acute gastrointestinal hemorrhage and it was resolved by using the endovascular embolization. ConclusionsPreoperative distinguishing IgG4 sclerosing cholangitis from hilar cholangiocarcinoma can avoid an unnecessary surgery. Endovascular intervention is both a useful measure of diagnosis and treatment for gastroduodenal pseudoaneurysm. Attention should be paid to arterial protection during process of arterial osteogenesis in hepatobiliary operation.
Objective To summarize the revascularization method of infective femoral false aneurysm caused by drug injection. Methods Between November 2003 and May 2009, 84 patients with infective femoral false aneurysm caused by drug injection were treated, and the cl inical data were analysed retrospectively. There were 67 males and 17 females with anaverage age of 34.6 years (range, 19-51 years). The average duration of drug injection was 2.7 years (range, 1-11 years). In 13 cases, the defect of femoral artery was 3-10 cm; defect ranged from 1.0 cm × 0.3 cm to 3.0 cm × 0.7 cm in the others. The surgical treatment included bypass using synthetic grafts in 5 cases, great saphenous veins transplantation in 29 cases, repair of femoral artery in 24 cases, and l igation of femoral artery in 26 cases. Results Two cases died of intraoperative pulmonary embol ism. Eight cases had postoperative wound infection, which was cured after changing dressings. Incisions healed by first intention in the other paitents. A total of 82 cases were followed up 12-36 months (mean, 17.3 months). In 56 patients undergoing artery reconstruction or repair, dorsal pedis artery pulse was significantly improved, and no distal osteofascial compartment syndrome occurred. In 26 patients undergoing femoral artery l igation, angiography at 1 week after operation showed abundant collateral circulation from ipsilateral internal il iac artery, superior gluteal artery or contralateral internal il iac artery. Three cases had postoperative intermittent claudication which was improved after symptomatic treatment. Conclusion Infective femoral false aneurysm caused by drug injection should be treated surgerically as early as possible, and effective treatments include debridement, drainage, defect repair or bypass with synthetic graft or great saphenous vein from homonymy external il iac artery to superficial femoral artery. Ligation of femoral artery is an option in patients with serious infection when revascularization is impossible.
Objective To carry out the systematic clinical management to reduce the incidence of femoral pseudoaneurysm after interventional treatment. Methods A historical controlled study was used to compare the management effect before (from October 2012 to October 2013) and after (from March 2014 to March 2015) the application of doctor-nurse integrated systematic clinical management mode. This work mode enhanced cooperation between doctors and nurses, formed the clinical path for nursing workflows and contingency plans, and strengthened specialized education and training for nurses. Results After the implementation of systematic clinical management, the incidence of femoral pseudoaneurysm was significantly lower than before (1.0% vs. 2.7%), and the difference was statistically significant (P<0.05). Conclusions The systematic clinical management, carrying out in the doctor-nurse integration mode, can improve the quality of nursing and reduce the incidence of femoral pseudoaneurysm. And the management model has achieved remarkable results. So it is worth to be applied in the clinical practices.
