  • Surgical Treatment of Infected Femoral Artery Pseudoaneurysm

    Objective To evaluate surgical treatment of infected femoral artery pseudoaneurysm. Methods The data on surgical treatment of 45 patients with infected femoral artery pseudoaneurysm admitted from January 2003 to June 2008 were analyzed retrospectively. Fourty-three patients underwent operative treatment including excision of infected femoral artery pseudoaneurysm, exhaustive debridement and bypass graft with vascular prosthesis. Two patients were unavoidable to undergo removing of infected femoral artery pseudoaneurysm and ligating the proximal and distal artery of pseudoaneurysm because of severe infection and large volume. Results The patients were followed up from 3 to 12 months (mean 7.82 months). The limbs of all the patients underwent bypass graft with vascular prosthesis were salvaged successfully, patients of which had secondary wound healing and had not intermittent lameness. One of two patients performed ligation of artery was salvaged successfully but had severe intermittent lameness, another patient underwent high amputation above knee because of ischemic gangrene. Conclusion For infected femoral artery pseudoaneurysm, the operative treatment including excision of infected femoral artery pseudoaneurysm, exhaustive debridement and bypass graft with vascular prosthesis is effective and safe.

  • EFFECTIVENESS COMPARISON BETWEEN ENDOVASCULAR RECANALIZATION AND OPEN SURGICAL REVASCULARIZATION TO TREAT PERIPHERAL PSEUDOANEURYSM

    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.

  • Early and Midterm Results of Endovascular Repair of Pseudoaneurysms of Descending Aorta

    Objective To summarize our clinical experience of endovascular repair of aortic pseudoaneurysms,andexplore the etiology of the disease,treatment indications,and early and midterm results of the procedure. Methods From November 2009 to May 2012,52 patients with aortic pseudoaneurysms received endovascular aortic repair (EVAR) in FuWai Hospital. There were 44 male and 8 female patients with their age of (53.8±13.5 ) years. Their onset syndromes includedchest or back pain in 46 patients and hoarseness in 5 patients. There were 23 acute patients and 29 chronic patients. Aortic pseudoaneurysms located at the descending thoracic aorta in 51 patients and the abdominal aorta in 1 patient. The meandiameter of the aortic pseudoaneurysms was (45.1±33.8) mm. All the patients were diagnosed using enhanced CT scan of the aorta. Three patients received emergency EVAR. All the patients received EVAR through the femoral arteries under general anesthesia. Forty-six patients underwent isolated EVAR,5 patients received hybrid technique for EVAR via the neck,and 1 patient received hybrid technique including EVAR and total arch replacement via median sternotomy under normothermia. The average diameter of stent-grafts was (34.2±3.3) mm and the average length was (157.7±20.3) mm. Enhanced CT scan of the aorta was performed before discharge,3 months and 1 year after EVAR during follow-up. Results There was no in-hospital death and EVAR was 100% successful. All the patients (100%) were followed up for 1-31 (12.6±7.9)months after discharge. Their chest or back pain symptoms all significantly improved. Their hoarseness improved too duringfollow-up. One patient’s hoarseness disappeared early after EVAR but recurred 5 months after EVAR. Enhanced CT scan showed enlargement of the stent-graft without endoleak. One patient underwent emergency EVAR for sudden onset of massivehemoptysis,recovered well before discharge,and was readmitted to hospital 5 months after EVAR because of fetid sputum and hemoptysis,who was diagnosed as Behcet’s disease and cured after anti-infection and immunosuppressive therapy. One patient had recurrent fever before and 6 months after EVAR and was cured by antibiotic therapy. Intraoperative angiographyshowed trivial typeⅠendoleak in 4 patients right after stent-graft deployment,which disappeared in enhanced CT scan 3-6 months after EVAR. Intraoperative angiography showed no endoleak in all the other patients,and their enhanced CT scans 3 months and 1 year after EVAR showed complete sealing between the stent-grafts and the aortic wall,thrombus in the pseudoaneurysm sac and decreased diameters of the pseudoaneurysms without endoleak. Two patients had hemiplegia 1 dayand 6 days after EVAR respectively,1 patient was cured and discharged and the other patient survived with hemiplegicsequelae. One patient with an abdominal aortic pseudoaneurysm died of sudden onset of cerebral infarction at home 3 monthsafter EVAR. Conclusions Endovascular repair of descending aortic pseudoaneurysms is safe and effective with good early and midterm results,and longer follow-up is needed for its long-term outcomes. Individualized treatment plan is basedon the location of the pseudoaneurysms. Preoperative meticulous medical history and physical examination are both importantfor the differentiation of the etiology of aortic pseudoaneurysms. Postoperative treatment based on the etiology and close follow-up are also needed to ensure long-term results.

  • Midterm follow-up results and postoperative aortic remodeling of blunt aortic injuries after endovascular treatment

    ObjectiveTo summarize the mid-term follow-up results and postoperative aortic remodeling of treating blunt aortic injuries (BAI) with thoracic endovascular aortic repair (TEVAR).MethodsA retrospective study was conducted on BAI patients treated with TEVAR, who were admitted into the Department of Vascular Surgery in Zhongshan Hospital, Affiliated to Fudan University between September 2003 and December 2015. There were 15 males and 9 females at an average age of 45.6±14.0 years. The mechanism of BAI was mainly auto car crash. Totally 25 entry tears were detected and most of them were located at the aortic isthmus.ResultsTwenty-four BAI patients survived and eventually went through TEVAR. One patient died of pulmonary embolism 1 week post-TEVAR. Rate of technical success, clinical success and perioperative mortality was 100.0%, 95.8%, and 4.2%, respectively. Nineteen patients were followed up with a mean time of 35.1(13-87) months. All of them survived this period. Based on the follow-up imaging of CTA, 18 of them revealed no endoleak or stent migration, and 1 patient of transection still had perfusion of distal false lumen at the abdominal aorta. None of the aortic segments measured in this study showed expansion of ≥5 mm during follow-up. The aorta remodeled well in 94.7% of them.ConclusionTEVAR for treating BAI appears feasible with high rates of technical and clinical success rates. The mid-term follow-up results seems satisfying, but the long-term results are yet to be assessed with further follow-up.
