目的分析破裂型腹主动脉瘤(ruptured abdominal aneurysm,r AAA)行腔内修复术(endovascular aortic aneurysm repair,EVAR)与开放手术早期结果,评价EVAR治疗的效果。方法回顾性收集我院2004年1月~2014年1月收治的48例r AAA患者临床资料,根据其手术与否、手术方式的不同分为术前死亡组(n=20)、EVAR组(n=14)和开放手术组(n=14),三组性别、年龄等一般资料比较无统计学差异(P0.05),EVAR组和开放手术组在瘤体直径、收缩压、舒张压方面比较差异均无统计学意义(P0.05)。结果 EVAR组入院至检查时间为(1.2±0.8)h,与开放手术组(7.5±7.1)h比较差异有统计学意义(P=0.006);EVAR组检查至手术时间为(1.8±1.3)h,与开放手术组(16.8±17.7)h比较差异有统计学意义(P=0.007)。死亡组入院至死亡时间与EVAR组比较差异有统计学意义(P0.009)。EVAR组手术时间为(2.3±0.7)h,与开放手术组(5.6±2.0)h比较差异有统计学意义(P0.001);EVAR组的术中出血量为(142.9±279.3)ml,与开放手术组的(3 528.6±3 252.3)ml间差异有统计学意义(P0.001);EVAR组的输血量为(985.7±2 148.7)ml,与开放手术组的(3 100.0±2 285.1)ml间差异有统计学意义(P=0.018);EVAR组的住院时间为(7.1±2.7)d,与开放手术组的(13.7±4.9)d间差异有统计学意义(P0.001);EVAR组的总费用为(20.9±5.8)万元,与开放手术组的(10.1±11.5)万元间差异有统计学意义(P=0.005)。两组并发症率比较,差异无统计学意义(P=0.430)。结论缩短院内抢救准备时间,是r AAA成功救治的要点。EVAR应作为r AAA的一线治疗方案。 相似文献

腹主动脉瘤腔内修复术最早于1991年被报道,目前已经发展成为一项成熟可行的技术,但在术后并发症发病率及手术死亡率方面仍存在着相当高的风险。如果腹主动脉瘤腔内修复术欲在未来完全取代传统手术,降低围手术期死亡率并提高长期疗效势在必行。以下将围绕腹主动脉瘤腔内修复术并发症的产生机制、发病率及其带来的问题进行讨论。 相似文献

Endovascular aneurysm repair (EVAR) is recognized as a minimally invasive alternative to open surgical repair of abdominal aortic aneurysms. However, endoleaks complicate nearly 20–25% of EVAR procedures. We discuss the detection and classification of endoleaks. In addition, we describe different strategies for Type 2 endoleak repair. 相似文献

目的:比较腹主动脉瘤腔内修复术与开放手术的疗效。方法:对35例肾下型腹主动脉瘤患者分别进行开放手术(21例)与腔内修复术(14例)治疗,比较两组术前评估、手术、围手术期及术后随访情况。结果:腔内修复组年龄较高(P〈0.05),手术时间、术中出血量、输血量较开腹手术低(P〈0.01),所需营养支持、监护、卧床时间短(P〈0.01),围手术期并发症发生率低(P〈0.05),但远期并发症发生率较高(P〈0.05)。结论:腹主动脉瘤腔内支架治疗较为安全,创伤更小,患者恢复速度较快,适合于高龄及合并症较多的患者。传统开放手术适于年轻、合并症少及无法行腔内修复术的患者。 相似文献

Purpose: The purpose of this study was to evaluate tranexamic acid (TA) for the prevention of type II endoleak (EL2) at a high level of evidence by a randomized controlled trial.Methods: Patients who underwent endovascular aneurysm repair (EVAR) between May 2017 and January 2020 were included. Patients in the TA group were given 750 mg of TA daily for a month after EVAR. The incidence of EL2, blood coagulation/fibrinolytic ability, and changes in aneurysm diameter were compared between two groups.Result: On the 7th day after EVAR, EL2 was found in 14 patients (34.1%) in the TA group and in 7 patients (15.9%) in the non-TA group. It was also found in 12 patients (29.3%) in the TA group and 6 patients (13.6%) in the non-TA group at 1 month after EVAR. There was no significant difference in the incidence of EL2 between the two groups (p = 0.051, 0.08). Blood tests revealed that fibrin degradation product and D-dimer were significantly suppressed in the TA group, there was no significant difference in the change of diameter regardless of the TA intake.Conclusion: This study proved anti-fibrinolytic effect of the TA, but it alone had not enough power to decrease EL2 after EVAR. 相似文献

BACKGROUND: successful endovascular repair of abdominal aortic aneurysms (AAA) generally leads to a decrease in aneurysm size. Theoretically, this may lead to foreshortening of the excluded segment. If so, vertically rigid endografts may dislocate over time and cover renal or hypogastric arteries. AIM: to assess length changes of the infrarenal aorta after endovascular AAA exclusion. PATIENTS AND METHODS: forty-four consecutive patients were scheduled for the EndoVascular Technologies endograft, a vertically non-rigid prosthesis which would potentially accommodate longitudinal changes. Twenty-four patients had completed at least 6 months of follow-up. In 18/24 patients a decrease in size was established by aneurysm volume measurements at 6 months' follow-up. Helical computer tomography (CT) angiograms were processed on a workstation. Aortic lengths were measured along the central lumen line from the lower renal artery orifice to the native aortic bifurcation. The computer tomography angiogram (CTA) reconstruction thickness of 2 mm yields at least a 4-mm error for each length measurement. RESULTS: in the shrinking aneurysm group, the median length change was 0 mm (range -9 mm to +4 mm) at 6 months' follow-up (n =18) and also 0 mm (range -7 mm to +4 mm) at 12 months' follow-up ( n =10). In 16/18 patients, length changes remained within the measurement error range of 4 mm. CONCLUSION: in this group of shrinking aneurysms after endovascular AAA repair, foreshortening of the excluded aortic segment appears not to be a clinically significant problem. 相似文献

Endovascular grafting of abdominal aortic aneurysms should be offered only to those patients with suitable anatomy. This is especially true at the level of the proximal aortic neck in order to secure long-term proximal fixation. Aortoiliac anatomy is easy to understand conceptually, however, it is difficult to define and measure quantitatively. In this article, we discuss the use of three dimensional computed tomographic angiography to determine aneurysm morphology and select patients for endovascular repair. Specifically, we apply our methods to define and measure angulation of the aorta and iliac arteries. The anatomic definition of the angulation of the proximal aortic neck is emphasized. 相似文献
