复合术式治疗复杂型下肢动脉硬化闭塞症疗效分析及其影响因素的研究

目的探讨复合术式(球囊扩张、支架植入联合内膜剥脱及取栓)治疗复杂型下肢动脉硬化闭塞症(ASO)的远期疗效及其相关影响因素。方法回顾性分析2005年1月至2009年11月间,复合术式(球囊扩张+支架置入、内膜剥脱+介入、导管取栓+介入)治疗318例ASO患者的临床资料,其中糖尿病性下肢动脉硬化闭塞症(DASO)198例(61例为双侧病变)259侧肢体,非糖尿病性下肢动脉硬化闭塞症(NDASO)120例(41例为双侧病变)161侧肢体。随访6～36个月,分析患者腘动脉以下血管及股浅动脉的通畅率及其相关影响因素。结果 318例患者中首次治疗成功率分别为DASO腘动脉以下血管90%,股浅动脉血管92%,NDASO腘动脉以下血管91%,股浅动脉血管94%,随访6～36个月,DASO腘动脉以下血管通畅率明显低于NDASO腘动脉以下血管通畅率。DASO腘动脉以下血管累积二次通畅率为89%～67%,股浅动脉血管累积二次通畅率为93%～73%。支架植入组的狭窄率显著低于非支架植入组(P0.05)。DASO的血管的通畅率减低与吸烟史、高血压、血糖控制不稳等因素有关。无围术期死亡及严重并发症发生。结论复合术式治疗下肢动脉硬化闭塞症适应范围广泛,疗法肯定。控制相关影响因素,可有效提高疗效。     

逆行开通技术治疗TASCⅡ C/D型股腘动脉硬化闭塞症

目的探讨逆行开通技术治疗TASCⅡ C/D型股腘动脉闭塞病变的价值。方法回顾性分析于我院接受逆行开通技术治疗的TASCⅡ C/D型股腘动脉硬化闭塞症患者36例。比较术前与术后踝肱指数(ABI)及间歇性跛行距离,分析术后血管通畅率及并发症。结果 36例均成功开通,术后7天及3、6、12个月间歇性跛行距离和ABI均较术前均明显增加(P均0.05)。术后3、6及12个月患肢血管通畅率分别为97.22%、91.67%及72.22%。随访期间无死亡或截肢,围手术期并发症发生率11.11%(4/36)。结论逆行开通技术可作为顺行开通TASCⅡ C/D型股腘动脉硬化闭塞症失败后的一种补救方法。     

股深动脉血运重建治疗下肢缺血的应用现状

下肢动脉硬化闭塞症的治疗,已经从内膜剥脱术、人工血管或自体大隐静脉旁路开放式手术为主发展到如今以血管腔内治疗为主。但是当股浅动脉发生长段闭塞时,无论是对于开通股浅动脉的开放手术或者血管腔内治疗,效果都难以达到预期。此时股深动脉由于其特殊的生理条件可以为下肢提供充足的血液供应,本文就股深动脉的解剖位置、手术入路、手术方式...     

超声引导下腘动脉逆行穿刺在股浅动脉长段闭塞介入治疗中的应用

目的探讨超声引导下腘动脉逆行穿刺在股浅动脉长段闭塞介入治疗中的应用价值。方法分析本院2013年8月至2017年11月应用超声引导下腘动脉逆行穿刺后行双向内膜下血管成形术(SAFARI)或内膜下血管成形术(SIA)治疗的25例患者资料。患者均在超声引导下逆行穿刺腘动脉,然后介入引导下行SAFARI或SIA,比较患者手术前后症状及踝肱指数(ABI)的变化。结果 25例患者穿刺均获得成功,其中18例行SAFARI,7例行SIA,无严重并发症发生,7例患者腘动脉穿刺鞘未使用。ABI由术前平均0.37±0.19提高至术后1周的0.78±0.23,差异有统计学意义(P0.05)。手术时间为60~175分钟,平均(126±15)分钟,超声引导下腘动脉逆行穿刺时间为3~11分钟,平均(6±2)分钟。术中造影剂用量为40~125 ml,平均(75±15)ml。结论超声引导下腘动脉逆行穿刺后行SAFARI或SIA是股浅动脉长段闭塞介入治疗的一种新思路,能缩短手术时间、减少造影剂用量、降低射线接触量;但带来的收益与腘动脉穿刺点并发症带来的风险之间的利弊权衡,需进一步探讨。

目的:探讨逆向入路支架植入治疗肠系膜上动脉(SMA)闭塞的技术。方法:回顾2017年2月1例于复旦大学附属中山医院血管外科行逆向开通SMA闭塞的患者临床资料。结果:患者为47岁女性,诊断为SMA闭塞引起的慢性肠系膜缺血(CMI),行腔内治疗再通SMA。由于SMA开口处完全闭塞性,无残端,经肱动脉和股动脉双侧入路均无法开通病变部位。利用腹腔干和SMA之间的胃十二指肠弓,通过此通路逆向开通SMA闭塞处;肱动脉入路导管和导丝对接后顺利正向通过病变,完成球囊扩张和支架植入术。术后患者CMI症状消失,3个月后随访CTA显示,支架定位良好,远端血管通畅。结论:对于常规血管内介入治疗方法失败的SMA闭塞患者,通过有效的侧支通路进行逆行开通是可行的。     

Percutaneous retrograde recanalization of an occluded celiac artery complicating acute aortic dissection

A 79-year-old woman with a complaint of persistent upper abdominal pain was admitted to our hospital for the treatment of thrombosed acute type B aortic dissection. Computed tomography showed the complete static occlusion of the celiac artery. Because of progressive symptom with elevation of liver enzymes and metabolic acidosis 11?h after admission, endovascular revascularization was attempted on an emergent basis. After a failed catheterization of the celiac ostium in an antegrade fashion due to a hard occlusion, we succeeded in a retrograde recanalization through the pancreaticoduodenal arcade via the superior mesenteric artery with stent placement using a pull-through technique. This technique is useful and safe when an antegrade approach seems difficult.     

Outpatient treatment of arterial inflow stenoses of dysfunctional hemodialysis access fistulas by retrograde venous access puncture and catheterization

OBJECTIVE: To determine the feasibility of endovascular treatment of inflow stenoses in arteriovenous fistulae (AVFs) through retrograde venous access catheterization. METHODS: We included all 22 dysfunctional AVFs with arterial inflow stenoses at access imaging between January 2002 and September 2006. Following retrograde venous access puncture, an interventional radiologist intended to cross the arteriovenous anastomosis and advance a catheter into the aortic arch. After depiction of the complete vascular access tree, angioplasty and/or stent placement was aimed for stenoses with a >50% luminal diameter reduction at digital subtraction angiography (DSA). RESULTS: In one radiocephalic AVF, a catheter could not be positioned into the aortic arch after retrograde venous access puncture. DSA depicted 28 inflow stenoses in the remaining 21 patients (11 radiocephalic AVFs and 10 brachiocephalic AVFs). Clinical improvement was obtained in 18 out of 19 patients with a technically successful intervention (<30% residual stenosis after angioplasty or stent placement). Following endovascular therapy, access flow of 12 patients with a low flow access improved from 431 +/- 150 ml/min to 818 +/- 233 ml/min, and four patients with steal symptoms became symptom free. One nonmaturing fistula could be salvaged by angioplasty, and access cannulation problems were solved in another patient following angioplasty. Brachial artery stent placement did not reduce steal symptoms in one case, whereas two patients, in whom stent placement was not thought desirable, showed a >30% residual arterial stenosis after angioplasty. No complications were observed at DSA and endovascular intervention. CONCLUSION: Retrograde venous access puncture and catheterization, as an alternative to a potentially more hazardous brachial artery or more invasive femoral artery approach, should be considered for the visualization of the arterial inflow and endovascular treatment of inflow stenoses.     

Balloon-expandable endobypass for femoropopliteal atherosclerotic occlusive disease:: A preliminary evaluation of fifty-five patients

Purpose: The purpose of this study was to evaluate the early results of a newly developed endovascular technique for the treatment of superficial femoral artery occlusion.Methods: Fifty-five patients with total occlusion of the superficial femoral artery with patent popliteal artery were treated and evaluated over a 21-month period. The endovascular treatment was performed through a groin incision and consisted of a recanalization of the occluded femoral artery, balloon dilatation, and intraluminal placement of a 3-mm polytetrafluoroethylene graft, distal fixation with a stent, dilation of the graft, and proximal suture anastomosis in the common femoral artery.Results: At a 1-year follow-up the Kaplan-Meier method revealed a primary patency rate of 73.1% (95% confidence limits: 59.6 to 86.6) and a secondary patency rate of 86.3% (range 75.8% to 96.9%). The procedure morbidity rate was 3.6%; the mortality and amputation rate at 12 months was nil.Conclusions: The early 1-year results of this endovascular study support the concept that femoropopliteal endobypass for atherosclerotic occlusive disease may be an acceptable alternative to classic direct femoropopliteal bypass operations. Further study is necessary. (J Vasc Surg 1996;24:647-54.)     

髂动脉硬化闭塞性病变的介入治疗技术及体会

目的探讨应用内膜下血管成形术(SIA)联合经皮血管腔内成形术(PTA)介入治疗髂动脉硬化闭塞性病变的技术方法和疗效。方法对15例伴有严重缺血症状的髂动脉硬化闭塞性病变患者,采用顺行途径穿刺,经左肱动脉穿刺3例,经对侧股动脉穿刺12例。通过SIA对闭塞段动脉进行再通,应用球囊扩张成形并植入支架(裸支架18枚,覆膜支架4枚)。结果内膜下血管成形术技术成功率100%,支架植入后髂动脉闭塞段管腔形态良好,血流通畅,无严重并发症出现,临床症状消失或明显改善。患肢踝肱指数由术前的0.41±0.12增至术后7天的0.81±0.13(t=8.76,P0.0001)。近中期随访2例发生再狭窄,经PTA解除,术后12个月支架一期通畅率为85.71%(12/14)。结论 SIA联合支架植入术治疗髂动脉硬化闭塞性病变安全、有效,近、中期疗效良好。     

Subintimal angioplasty of a crural vessel via an antegrade popliteal artery puncture.

Percutaneous retrograde puncture of the popliteal artery is a well-described technique and offers an alternative site for access to the peripheral vascular system. Antegrade popliteal artery puncture has only been described once in the literature. We present a case of subintimal angioplasty of a crural vessel occlusion using an antegrade popliteal approach. This report highlights that if other access is not possible due to unfavourable anatomy this approach is a technically feasible option.     

Surgical implications of early failed endovascular intervention of the superficial femoral artery

BACKGROUND: It is generally accepted that failed infrainguinal bypass with prosthetic material significantly compromises arterial run off, which may limit future revascularization. It is well known that the negative consequences of early vein graft thrombosis are limited, but the effect of failed peripheral angioplasty on the distal vasculature is poorly studied. The purpose of this study was to determine whether early failure after superficial femoral artery intervention influences subsequent revascularization options. METHODS: Between July 1, 1998, and June 30, 2006, 276 patients underwent endovascular intervention of the superficial femoral artery. A prospective analysis of angiograms done before the intervention and after early failure (相似文献

Aneurysmal Degeneration of the Superficial Femoral Artery following Stenting: An Uncommon Infectious Complication

Infrainguinal angioplasty and stenting is becoming a more commonly performed procedure. Its durability remains a matter of debate, however. Aneurysmal degeneration following angioplasty and stenting is a complication not previously described in the literature with regard to the superficial femoral artery. We present a case in which two aneurysms of the superficial femoral artery developed following angioplasty and multiple-stent placements in a patient who had previously undergone a failed femoral-to-below-the-knee popliteal artery PTFE bypass graft. The patient presented to our institution with an occluded, infected bypass graft. He was treated with graft and femoral artery/stent excision and vein bypass grafting. A brief review of infectious complications after stent placement is included.     

经腹小切口超声引导系膜穿刺逆向开通治疗肠系膜上动脉开口全堵病变

背景与目的：对于肠系膜上动脉（SMA）闭塞患者,尤其是存在开口处动脉粥样硬化性无残端病变,开腹逆行肠系膜动脉支架置入术（ROMS）是一种有效的治疗方法,但该手术创伤较大,一些身体条件差的患者并不适合。笔者通过报告1例SMA全堵病变病例的治疗过程介绍一种改良的微创ROMS技术,以期为临床治疗方法的选择提供参考。 方法：回顾复旦大学附属中山医院厦门医院血管外科2019年10月收治的1例SMA全堵病变患者的临床资料。患者为64岁女性,诊断为SMA闭塞引起的慢性肠系膜缺血,行杂交手术再通SMA。 结果：患者SMA开口处为无残端完全闭塞病变且无侧支血管与腹腔干动脉及脾动脉沟通,顺行或逆行血管腔内开通均无法进行。因患者全身条件较差,难以耐受开放血运重建手术和传统的ROMS。遂做腹部做小切口,超声引导下经系膜穿刺SMA远端建立通路,导丝顺利逆向通过SMA闭塞处进入降主动脉;右侧肱动脉入路导管和逆向导丝对接后顺利正向通过病变,完成球囊扩张和支架置入术。术后患者恢复良好,症状消失,3个月后随访CTA示,支架形态、位置良好,血流通畅。 结论：对于血管腔内治疗失败且全身条件较差的SMA闭塞患者,通过经腹小切口超声引导系膜穿刺逆向开通SMA是可行的。
