Acute occlusion of the left main coronary artery is normally fatal. According to the literature, only a few cases have been treated by intracoronary thrombolysis; the prolonged period of ischemia, however, resulted in severe left ventricular dysfunction and numerous complications. Therefore, effort should be directed to recanalize the left main coronary artery within the shortest possible interval. We followed this approach in a case of acute occlusion of a subtotal stenosis of the left main coronary artery which could be mechanically reopened and dilated within a few minutes. The intervention resulted in immediate reversal of profound cardiogenic shock and complete restoration of normal left ventricular function. At hospital discharge, the patient was asymptomatic with a negative bicycle stress test. Immediate mechanical recanalization and angioplasty appear to be a feasible approach in life-threatening coronary occlusion. 相似文献

Residual Flow Signals Predict Complete Recanalization in Stroke Patients Treated With TPA 总被引:4,自引:0,他引:4

BACKGROUND: Residual blood flow around thrombus prior to treatment predicts success of coronary thrombolysis. The authors aimed to correlate the presence of residual flow signals in the middle cerebral artery (MCA) with completeness of recanalization after intravenous tissue plasminogen activator (TPA). METHODS: The authors studied consecutive patients treated with intravenous TPA therapy who had a proximal MCA occlusion on pretreatment transcranial Doppler (TCD). Patients were continuously monitored for 2 hours after TPA bolus. Absent residual flow signals correspond to the thrombolysis in brain ischemia (TIBI) 0 grade, and the presence of residual flow signals was determined as TIBI 1-3 flow grades. Complete recanalization was defined as flow improvement to TIBI grades 4-5. RESULTS: Seventy-five patients with a proximal MCA occlusion had median pre-bolus NIHSS 16 (85% with > or = 10 points). TPA bolus was given at 141 +/- 56 minutes (median 120 minutes). Complete recanalization was observed in 25 (33%), partial in 23 (31%), and no early recanalization was seen in 27 (36%) patients within 2 hours after TPA bolus. Only 19% with absent residual flow signals (TIBI grade 0, n = 26) on pretreatment TCD had complete early recanalization. If pretreatment TCD showed the presence of any residual flow (TIBI 1-3, n = 49), 41% had complete recanalization within 2 hours of TPA bolus (P = .03). CONCLUSIONS: Patients with detectable residual flow signals before IV TPA bolus are twice as likely to have early complete recanalization. Those with no detectable residual flow signals have less than 20% chance for complete early recanalization with intravenous TPA and may be candidates for intra-arterial therapies. 相似文献

Laser recanalization of peripheral artery occlusions was performed in 338 patients. A continuous wave Nd-YAG laser was used in combination with sapphire-probe laser catheters. The initial recanalization rate was 85%. Complications such as dissections, perforations, emboli and spasm were observed in 14%. The cumulative patency rate after 3 years was 48%. 相似文献

重组竹叶青蛇毒纤溶酶原激活剂TSV-PA体内溶栓效应观察 总被引:4,自引:0,他引:4
目的:观察重组竹叶青蛇毒纤溶酶原激活剂TSV—PA体内溶栓效应。方法:利用家兔制备的脑血栓模型,以生理盐水和尿激酶为对照,用数字减影血管造影技术观察重组竹叶青蛇毒纤溶酶原激活剂TSV—PA体内溶栓效果。结果:TSV—PA高剂量实验组(300μg/kg)再道时间为2h以内,TSV—PA低剂量实验组(150μg/kg)5h以内再通。尿激酶组(2000U/kg)再通时间为3—6h;24h以内生理盐水对照组没有观察到再通现象。实验动物45h后处死解剖,未观察到出血现象和其它异常现象。结论:重组TSV—PA在体内具有良好的溶栓活性。 相似文献

三种输卵管疏通术治疗后发生输卵管妊娠的临床分析 总被引:12,自引:0,他引:12
目的 :了解输卵管疏通术后发生输卵管妊娠的危险因素及其相应对策。方法 :回顾性分析 6 9例输卵管性不孕者分别经三种输卵管疏通术后发生输卵管妊娠 (TP)的患者 ,分成 3组 ,比较 3组疏通术前子宫输卵管碘油造影(HSG)结果和疏通术后通畅与非通畅输卵管的TP发生率。结果 :疏通术前 ,示输卵管柔软 5 7条 (34例 ) ,发生TP 2 1例(6 1.8% ) ,而欠柔软 /僵硬 79条 (5 6例 ) ,发生TP 4 8例 (85 7% ) ,两者差异有显著意义 (P <0 0 5 ) ;输卵管周围有无粘连者TP发生率差异也存在显著意义 (P <0 0 5 )。无论畅与不畅 ,3组术后TP发生率间差异无显著意义 (P >0 0 5 )。结论 :疏通术前HSG提示输卵管欠柔软、僵硬以及存在周围粘连者可能是疏通治疗后输卵管妊娠发生的危险因素。对于此类病变严重的输卵管不宜选择疏通术治疗。 相似文献

机械血栓切除术可治疗伴大血管闭塞的前循环和后循环急性缺血性脑卒中。机械血栓切除术失败后仍应进行支架植入术;接触抽吸术与支架取栓术的优劣难分仲伯;伴大血管闭塞的动脉粥样硬化性前循环急性缺血性脑卒中,血管成形术和(或)支架置入术要优于支架取栓术;支架取栓术加动脉内溶栓治疗有叠加效应,但机械血栓切除术加静脉溶栓则无叠加效应;远程缺血预处理和替罗非班有减少手术并发症的功效;紫杉醇洗脱支架和新型支架是值得推广的新型血管内治疗装置。 相似文献
