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。
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.
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 introduce the treatment and clinical result of reconstructing femoral artery with external jugular vein graft. Methods From June 2002 to April 2006, 22 cases of femoral artery defects caused by pseudoaneurysm resection, were reconstructed withexternal jugular vein graft by microsurgical technique. There were 20 males and2 females, aging 25-46 years (mean 31.2 years). The length of femoral artery defects was 5-9 cm, with an average of 6.8 cm. The location was left in 14 cases and right in 8 cases.Results Ten cases achieved healing by the first intention, and 4 cases by the second intention. The other 8 cases need the regional flap repair because the wound splited open and became ulcer. Femoral artery defects were reconstructed successfully and the pulse of dorsal arteries of foot could be felt except 1 case of bleeding of anastomotic rupture. Eighteen patients were followed up 1-30 months, and no pseudoaneurysm recurred. Color ultrasound Doppler detection showed that the external jugular veins took place of the femoral artery defects in 12 cases. Conclusion External jugular vein is stable at anatomy and easy-to-obtain. Its calibre is close to that of the femoral artery. It can be used for reconstructing femoral artery defects as the vein material. The operation is easy and the clinical result is sure.
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 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.
