作者采用Fogarty导管取栓辅以术中动脉内灌注国产蝮蛇抗栓酶的方法,治疗急性动脉栓塞47例,43例有效,35例保全了肢体。此法不但能取除主干动脉内的栓子,在一定时间还能保持动脉内高浓度的溶栓抗凝剂,从而有可能达到溶解残留血栓和防止继发血栓形成的目的。本组无手术死亡,术后无大出血和肝肾中毒性损害等并发症。提示此法安全可靠。 相似文献

目的比较手术取栓与介入取栓对下肢深静脉血栓形成(deep vein thrombosis,DVT)的近、远期疗效。方法回顾分析2000年3月~2008年8月167例混合型和中心型DVT的临床资料,其中手术取栓87例,介入取栓80例,术后均局部应用尿激酶溶栓、肝素抗凝治疗,后期应用华法林抗凝6~12个月。结果治疗后介入组双大腿及小腿周径差中位数分别为0.8cm(-3.0~6.0cm)和0.7cm(0.0~5.5cm),手术组分别为1.6cm(0.0~8.0cm)和1.1cm(0.0~4.5cm)(Z=-3.932,P=0.000;Z=-3.313,P=0.001)。介入组住院时间(7.7±4.9)d,显著短于手术组(14.7±6.5)d(t=7.806,P=0.000)。介入组腹膜后血肿、肺部感染、伤口感染、淋巴漏等总的并发症发生率为8.8%(7/80),显著低于手术组35.6%(31/87)(χ2=17.135,P=0.000)。131例随访(47.3±28.3)月,2组大、小腿周径差,主观症状评分,色素沉着,静脉曲张,间歇跛行发生率等方面均无显著差异(P0.05)。结论手术取栓与介入取栓相比,远期疗效相当,但介入取栓对于混合型和中心型DVT的治疗时间窗宽,近期疗效更佳,且住院时间短,并发症少。 相似文献

Endovascular intraarterial (IA) strategies have emerged as important treatment options for patients with acute ischemic stroke who are ineligible for intravenous (IV) tissue plasminogen activator (tPA) or in whom such therapy has failed. The goal of this article is to provide a comprehensive review of percutaneous IA endovascular techniques aimed at revascularization in the setting of acute ischemic stroke from IA thrombolysis, mechanical thrombectomy, and primary intracranial stenting to retrievable-stent technology. For each modality, we focus on the existing clinical data, including our institutional experience and techniques. 相似文献

Thrombectomy of a graft in ambulatory patients can be performed simply under local anesthesia, avoiding admission to hospital of patients with shunts. The technique is applicable to two types of shunt: arterio-arterial shunts for lower limb arteriopathy and arteriovenous shunts of a dialysis for chronic renal failure. The advantages are twofold: dissection of a subcutaneous graft is avoided and the patient can either immediately reinstitute activity if arteritic or dialysis for renal failure. The method is effective if the thrombus is of accidental origin, failures resulting from proximal or distal stenosis, their evaluation being possible during thrombectomy. 相似文献

We present the first case of documented clot in-transit through a patent foramen ovale (PFO), caused by mechanical thrombectomy of a clotted AV fistula. Embolus after access thrombectomy is a rare, but known complication of the procedure. Paradoxical embolus is likewise a rare consequence of a right-sided clot, embolising to the left-sided circulation in a patient with a PFO. Suspected embolus through a PFO after dialysis access thrombectomy has been reported, but no case has ever documented the clot in-transit through the PFO. 相似文献

Objectives
A model for assuring clamping success was established for laparoscopic partial nephrectomy (LPN) with segmental renal artery clamping (SRAC).Materials and methods
Patients (n = 107; December 2009–September 2011) who underwent LPN with SRAC dependent on the experience of the surgeon and CTA were retrospectively reviewed to determine the optimal characteristics of target arteries. After multiple logistic regression analysis, variables used to build a nomogram were selected using a backward elimination scheme. A model for a clamping program customized to the patient was designed. The surgical outcomes of patients (n = 141; October 2011–June 2014) who subsequently underwent LPN-SRAC with the applied model were compared with those of the first group of patients.Results
Five potential predictors were initially assessed: segmental renal artery angle, target artery diameter, and distance (d) to the abdominal aorta, renal hilum (d RH), and kidney midline (d KML). The regression equation was set up as: Comparing the patient groups, those for whom the new SRAC model was applied had a significantly better success rate of clamping (P < 0.001), less total operative time (P < 0.001), and less operative blood loss (P = 0.042). No obvious differences were observed in time of warm ischemia, postoperative hospitalization, RENAL nephrometry score, or number of final clamped branches.
$${\text{Clamping assurance}} = \frac{{{\text{e}}^{x} }}{{1 + {\text{e}}^{x} }},\quad {\text{where}}\,x = 12.360 + 4.863\left( {d_{\text{RH}} } \right) - 8.848\left( {d_{\text{KML}} } \right).$$
Conclusions
The model for assuring clamping success was helpful in designing an SRAC program and thus benefiting the LPN procedure.18.

目的 观察大鼠腹主动脉阻断术(AAC)后合并脓毒症时脊髓病理改变及肿瘤坏死因子(TNF)-α的表达.方法 Wistar大鼠32只,随机均分为四组:假手术组(A组),AAC组(B组),LPS组(C组),AAC+ LPS组(D组).所有动物均于再灌注后8h处死,处死前进行后肢神经功能评分,取脊髓行HE染色观察脊髓组织病理损害和免疫组化检测脊髓前角TNF-α的表达.结果 HE染色显示A组损伤较轻;B组可见炎性反应明显,较多神经元坏死;C组有炎性表现,较少神经元坏死,较多运动神经元凋亡;D组可见强烈炎性表现,大量神经元坏死.A组TNF-α少量表达,显著低于其它三组(P<0.01).C组TNF-α显著高于其它三组(P<0.01).A、C组后肢神经功能评分显著高于B、D组(P<0.05或P<0.01).结论 TNF-α在AAC后脓毒症急性脊髓损伤中发挥了重要作用,介导了运动神经元的坏死或凋亡.AAC后机体可存在免疫紊乱,如此时发生脓毒症,TNF-α表达增加可能不如单纯脓毒症明显. 相似文献
