Objective To evaluate repair and reconstructionof the femoral pseudoaneurysm caused by drug injection. Methods From May 2000 to May 2005, 15 cases of femoral pseudoaneurysm caused by drug injection underwent operation treatment. All patients were male, aging 20-36 years. The disease course was 18-52 days(mean 35 days) and the course of druginjection was 3-17 months. The locations were the left side in 5 cases and theright side in 10 cases. After having been bandaged with pressure and supportedwith nutrition, they had been all operated. One case received fistula repair, and 14 cases received vascular grafting with ePTFE man-made blood vessel. Results The wounds healed by the first intention in 14 cases. All limbs survived. The complexion, temperature and response of involved leg were in gear. The postoperative color ultrasound Doppler detection showed that all the vascular grafts were of patency. The function of the involved limbs restored to normal. Conclusion Complete debridement, vascular reconstruction and better microsurgery skill were the key factors of treating successfullythe femoral pseudoaneurysm caused by drug injection.
Abstract： Objective To evaluate clinical outcomes of plication of left ventricular aneurysm during off-pump coronary artery bypass grafting （OPCAB）. Methods A total of 114 patients who underwent coronary artery bypass grafting （CABG） and concomitant surgical treatment for left ventricular aneurysm from January 2007 to January 2011 in Beijing Anzhen Hospital were included in this study. All the patients were divided into 2 groups according to the different surgical procedures they received. In groupⅠ， there were 76 patients including 57 males and 19 females with their average age of （63.4±7.8） years who underwent CABG and left ventricular aneurysmectomy under cardiopulmonary bypass on the non-beating heart. In groupⅡ， there were 38 patients including 32 males and 6 females with their average age of （60.6±8.9） years who underwent OPCAB and plication of the left ventricular aneurysm on the beating heart. Preoperative data were not statistically different between the 2 groups except that the percentage of the left ventricular aneurysm to the left ventricle of groupⅠwas significantly larger than that of groupⅡ（42.2%±13.6% vs. 26.5%±12.3％， t=5.499， P=0.000）. Postoperative clinical outcomes and morbidities were compared between the 2 groups， and all the patients were followed up for 6 months. Results There was 2 in-hospital death in groupⅠ， one for postoperative refractory ventricular arrhythmia， and the other for severe pneumonia. There was 1 in-hospital death in groupⅡ because of perioperative myocardial infarction. Postoperative thoracic drainage， incidence of reexploration for bleeding， mechanical ventilation time and incidence of intra-aortic balloon pump （IABP） implantation were not statistically different between the 2 groups （P＞0.05）. To compare their echocardiography outcomes at early postoperative stage and 6 months after discharge with preoperative values， left ventricular end-diastolic dimensions （LVEDD） at early postoperative stage and 6 months after discharge were both signific antly decreased than preoperative value in both groups ［groupⅠ： （54.0±7.8） mm amp; （56.0±8.1） mm vs. （59.6±6.6） mm， groupⅡ： （52.0±7.2） mm amp; （53.6±5.3） mm vs. （57.9±5.4） mm］， and left ventricular ejection fraction （LVEF） at early postoperative stage and 6 months after discharge were both significantly higher than preoperative value in both groups （groupⅠ：43.5%±3.2％ amp; 55.7%±3.7% vs. 38.0%±7.4%， groupⅡ：44.7%±2.8％ amp; 57.0%±3.5% vs. 41.0%±6.6%）， but there was no statistical difference in LVEDD and LVEF between the 2 groups（P＞0.05）. Conclusion Plication of left ventricular aneurysm during OPCAB is a safe and effective surgical procedure， and possibly more appropriate for patients with a smaller left ventricular aneurysm.
Numerical simulation of stent deployment is very important to the surgical planning and risk assess of the interventional treatment for the cardio-cerebrovascular diseases. Our group developed a framework to deploy the braided stent and the stent graft virtually by finite element simulation. By using the framework, the whole process of the deployment of the flow diverter to treat a cerebral aneurysm was simulated, and the deformation of the parent artery and the distributions of the stress in the parent artery wall were investigated. The results provided some information to improve the intervention of cerebral aneurysm and optimize the design of the flow diverter. Furthermore, the whole process of the deployment of the stent graft to treat an aortic dissection was simulated, and the distributions of the stress in the aortic wall were investigated when the different oversize ratio of the stent graft was selected. The simulation results proved that the maximum stress located at the position where the bare metal ring touched the artery wall. The results also can be applied to improve the intervention of the aortic dissection and the design of the stent graft.
Surgical intervention for chronic thoracoabdominal aortic dissecting aneurysms (cTAADA) is regarded as one of the most challenging procedures in the field of vascular surgery. For nearly six decades, open repair predominantly utilizing prosthetic grafts has been the treatment of choice for cTAADA. With advances in minimally invasive endovascular technologies, two novel surgical approaches have emerged: total endovascular stent-graft repair and hybrid procedures combining retrograde debranching of visceral arteries with endovascular stent-graft repair (abbreviated as hybrid procedure). Although total endovascular stent-graft repair offers reduced trauma and quicker recovery, limitations persist in clinical application due to hostile anatomical requirements of the aorta, high costs, and the lack of universally available stent-graft products. Hybrid repair, integrating the minimally invasive ethos of endovascular repair with visceral artery debranching techniques, has increasingly become a significant surgical modality for managing thoracoabdominal aneurysms, especially in cases unsuitable for open surgery or total endovascular treatment due to anatomical constraints such as aortic tortuosity or narrow true lumens in dissections. Recent enhancements in hybrid surgical approaches include ongoing optimization of visceral artery reconstruction strategies based on hemodynamic analyses, and exploration of the comparative benefits of staged versus concurrent surgical interventions.
Objective To investigate the early effectiveness of total percutaneous endovascular aneurysm repair (TPEVAR) in treating asymptomatic abdominal aortic aneurysm (AAAA) by comparing with surgical femoral cutdown endovascular aneurysm repair (SFCEVAR). Methods Between January 2010 and May 2011, 41 cases of AAAA were treated with TPEVAR in 26 cases (TPEVAR group) and with SFCEVAR in 15 cases (SFCEVAR group). The maximum tumor diameter ranged from 3.5 to 9.2 cm (mean, 5.7 cm) in TPEVAR group, and ranged from 3.5 to 10.0 cm (mean, 6.9 cm) in SFCEVAR group. There was no significant difference in gender or age between 2 groups (P gt; 0.05). Results All patients underwent EVAR successfully. The patients were followed up 6-23 months (mean, 13.5 months). No significant difference was found in the outer diameters of the delivery system for main body and iliac leg, operation time, contrast media dosage, hospitalization days, or postoperative hospitalization days between 2 groups (P gt; 0.05). The patients of SFCEVAR group had more bleeding volume and longer ICU stay than patients of TPEVAR group (P lt; 0.05). The incidence of minor complication was 7.7% (2/26) in TPEVAR group and 33.3% (5/15) in SFCEVAR group, showing no significant difference between 2 group (χ2=4.42, P=0.08); the incidence of major complication in SFCEVAR group (20.0%, 3/15) was significantly higher than that in TPEVAR group (0) (χ2=5.61, P=0.02). Conclusion TPEVAR shows safer and more effective than SFCEVAR in treating AAAA.
ObjectiveTo summarize surgical treatment experience on unruptured aneurysm of the sinus of Valsalva (SVA). MethodsClinical data of 33 patients with unruptured SVA underwent surgical repair at Fu wai Hospital between February 2007 and January 2012 were retrospectively analyzed. There were 27 males and 6 females with their mean age of 28.5±13.5 years (ranged from 4.5 to 58.0 years). The unruptured SVA originated in the right coronary sinus in 29 cases (87.8%), in non-coronary in 2 cases (6.1%) and in left coronary sinus in 2 cases (6.1%). There were 29 cases with ventricular septal defect and 20 cases with aortic valve insufficiency (AI). ResultsOnly 52.8% of unruptured SVA were correctly diagnosed by echocardiography preoperatively. All unruptured SVA received active surgical management, with no early death after operation. Thirty patients (90.9%) were followed up for 22 to 81 months (mean 42.9±18.8 months) and in NYHA classⅠorⅡ. None SVA recurrence occurred. Postoperative AI could be improved better by using the repair route only through the chamber of right ventricle for patients with unruptured SVA originated in right coronary sinus. ConclusionFor unruptured SVA patients who associated with other kinds of cardiovascular lesions, active surgical repair for unruptured SVA can achieve satisfactory results.
ObjectiveTo explore the changes of intraoperative temperature and influencing factors of the short-term prognosis of patients undergoing clipping of posterior communicating artery aneurysms.MethodsThe basic clinic data and intraoperative temperature of patients undergoing elective clipping of posterior communicating artery aneurysms between October 2018 and July 2019 were collected, and the minimum intraoperative temperature was categorized into ≥36.0 and <37.5℃, ≥35.0 and <36.0℃, and <35.0℃. According to the Glasgow outcome scale (GOS) at discharge, the patients were divided into good prognosis group (GOS 4-5) and bad prognosis group (GOS 1-3). Multiple logistic regression analysis was used to obtain the risk factors of short-term prognosis.ResultsA total of 127 cases were involved, and intraoperative hypothermia (<36.0℃) occurred in 64 cases (50.4%). The intraoperative temperature presented classical three-phrase changes, i.e. it dropped rapidly at 1 hour after anesthesia introduction, decreased slowly during 2-3 hours after anesthesia introduction, and then entered the plateau. In the 127 cases, 93 (73.2%) had good prognosis, with an intraoperative hypothermia proportion of 44.1% (41/93); and 34 (26.8%) had bad prognosis, with an intraoperative hypothermia proportion of 67.6% (23/34). Univariate analysis showed that Hunt-Hess grade (χ2=18.999, P<0.001), intraoperative bleeding (χ2=7.074, P=0.008), minimum intraoperative temperature (Z=−3.473, P=0.001), and postoperative complications (χ2=43.060, P<0.001) were related to the short-term prognosis of patients undergoing clipping of posterior communicating artery aneurysms. Multiple logistic regression analysis presented that high Hunt-Hess grade (Ⅳ, Ⅴ) [odds ratio (OR)=6.456, 95% confidence interval (CI) (1.141, 36.532), P=0.035], the minimum intraoperative temperature <35.0℃ [OR=7.552, 95%CI (1.450, 39.345), P=0.016], and postoperative complications [OR=22.866, 95%CI (6.778, 77.142), P<0.001] were independent risk factors of the short-term prognosis. The difference in short-term prognosis between patients with the minimum intraoperative temperature ≥35.0 and <36.0℃ and the ones with the minimum intraoperative temperature ≥36.0 and <37.5℃ was not statistically significant (P>0.05).ConclusionsThe minimum intraoperative temperature<35.0℃ and postoperative complications were changeable factors to effect progonosis of patients undergoing elective clipping of posterior communicating artery aneurysms. Clinical staff should set medical intervention measures based on the individual conditions of patients to improve patients’ quality of life.
The surgical treatment of thoraco-abdominal aortic aneurysm (TAAA) requires a unique multidisciplinary approach. A thorough preoperative examination and evaluation are essential to determine the optimal timing for surgery and to optimize organ function as needed. During the perioperative period, excellent surgical skills and an appropriate strategy for extracorporeal circulation will be employed based on the extent of the aneurysm. Additionally, necessary measures will be taken to monitor and protect the functions of vital organs. Close monitoring and management in the postoperative stage, along with early detection of complications and effective treatment, are crucial for improving the prognosis of TAAA surgery. This article reviews the current research progress in the perioperative management of TAAA surgery.
Objective To summarize selection of therapeutic method for isolated iliac aneurysms and analyze its advantages and disadvantages. Method The clinical data of 21 patients with isolated iliac aneurysms from January 2006 to January 2017 in this hospital were analyzed retrospectively. Results Four patients were treated with an open surgery such as the unilateral iliac prosthetic graft interposition, aorto-biiliac or aorto-bifemoral arterial bypass graft, ligation of internal iliac artery, etc.. Seventeen patients were treated with an endovascular treatment such as the unilateral iliac stent-grafts, bifurcated aortic stent-grafts, or coil embolization alone, etc.. One patient with ruptured isolated iliac aneurysms died during the endovascular repair, and the rest patients were cured after the operation. The average operative time was 2.83 h and 1.58 h, the average hospital stay was 17.5 d and 7.7 d respectively for the patients with the open surgery and the endovascular treatment. Except 1 case of type Ⅰ and 1 case of type Ⅱ endoleaks were found in the patients with the endovascular treatment, no complications such as the ureteral and intestinal injuries, the gluteal muscle claudication, and the sigmoid ischemia were found in all the patients. Seventeen cases were followed-up. The following-up rate was 85%. The following-up time was 1–60 months with an average of 22 months. During the following-up period, the grafts and stent grafts were patent and the aneurysm sac diameter was unchanged. The abscess of the iliac fossa occurred in 1 patient with systemic lupus erythematosus and improved after the symptomatic treatment. Two patients died of other diseases during the following-up period, and the rest had no obvious clinical symptoms. Conclusions Preliminary results of limited cases in this study show that endovascular repair and open surgery in treatment of appropriately selected patients with isolated iliac artery aneurysms is safe and effective. But in special situation, technical controllability of open surgery might be better than endovascular repair, treatment should be selected according to patient’s general condition and anatomy of aneurysm.
