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.

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.
The injuries of the femoral arteries were mistreated in 5 cases. The causes of the mistakes were resulted from: the initial cause of the injury was not carefully analyzed; the arterial injury was overlooked by the concomitant injuries, and the improper method of management was selected, as a result, 2 patients died from acute renal failure and the other 3 patients developed the complications of secondary thrombosis of the artery or rupture of the artery at the anastomotic site following repair. Of the 3 patients, 2 patients had recovered following reoperation and the other 1 patient had lost his limb from amputation. It should be emphasized that all of the following key points might avoid the mistakes occurred in the management of the injury of the femoral artery: (1) early diagnosis; (2) debredment of arteral end; (3) in infections wounds, insted of vein transplantation bypass technique should be done.
ObjectiveTo explore the ultrasonic morphological indexes influencing the effectiveness of ultrasound-guided thrombin injection (UGTI) in the treatment of iatrogenic femoral artey pseudoaneury (IFAP).MethodsThe patients with IFAP treated by UGTI in the West China Hospital of Sichuan University from 2015 to 2017 were collected according to the inclusion criteria. The demographic data, comorbidities, clinical symptoms, ultrasonic morphological parameters, thrombin dosage, and postoperative complications were analyzed. The risk factors of technical success of UGTI were analyzed by logistic regression analysis. The technical success was defined as absence of flow within the FAP immediately after UGTI. ResultsA total of 53 patients who met the criteria of inclusion were included in this study. The technical and treatment success rates of UGTI were 84.9% (45/53) and 96.2% (51/53), respectively. No deep venous thrombosis, arterial thromboembolism, infection, bleeding, allergy, and other complications or death occurred in all patients. There were no statistical differences in the age, clinical symptoms, comorbidities (except hypertension, P=0.040), ultrasonic morphological parameters (except femoral artery diameter, P<0.001), and thrombin dosage between the patients with technical success and failure (P>0.05). Multivariate logistic regression analysis showed that the smaller femoral artery diameter was the risk factor of the technical failure [OR=0.350, 95%CI (0.165, 0.743), P=0.006]. Further adjustment of thebaseline data of patients (excluding patients with hypertension), the logistic regression analysis still found that smaller femoral artery diameter was the risk factor of the technical failure [OR=0.419, 95%CI (0.205, 0.860), P=0.018].ConclusionsUGTI in treatment of IFAP is minimally invasive and has a higher technical success rate. Smaller femoral artery diameter might affect technical success rate of UGTI.
目的:探讨颈动脉(CA)、股动脉(FA)的内—中膜厚度(IMT)及其血流参数对高血压病的诊断价值。方法:对52例原发性高血压病患者利用高频超声进行CA、FA的IMT检查,并与45例正常对照组结果进行对比研究。结果:高血压组的受检者CA、FA的内中膜厚度较正常对照组的明显增厚,差异有统计学意义(Plt;0.01)。高血压组的受检者CA、FA内径较正常对照组增宽,有显著性差异(Plt;0.01)。高血压组与正常对照组的血流速度测量:高血压组CA、FA平均流速(MV)、加速度时间(AT)明显低于正常对照组,差异有统计学意义(Plt;0.01)。高血压组的CA收缩/舒张期血流速度比值(S/D),搏动指数(PI)、阻力指数(RI),均高于正常对照组,差异有统计学意义(Plt;0.01〉。高血压组的FA收缩/舒张期血流速度比值(S/D)、搏动指数(PI)、阻力指数(RI)与正常对照组比较差异无统计学意义。高血压组与正常对照组钙斑形成比较差异有统计学意义(Plt;0.01)。结论:高血压病的CA、FA内—中膜及血流参数均有不同程度改变,超声检查对临床预警和防治具有重要意义。
