To assess the relative efficacy of empiric gastroduodenal artery (GDA) embolization in reducing recurrent hemorrhage compared to image-guided targeted embolization.
Data were retrospectively collected for consecutive patients who had catheter angiography for major upper gastrointestinal hemorrhage from May 2008 to November 2010 (n = 40). The total number of cases were divided into two main groups according to angiographic findings: those that demonstrated a site of hemorrhage on catheter angiography (group 1, n = 13), and those where the site of hemorrhage was not identified on catheter angiography (group 2, n = 27). Group 2 was then further divided into patients who received empiric embolization (group 2a, n = 20) and those who had no embolization performed after angiography (group 2b, n = 7).
The technical and clinical success rates for embolization in groups 1 and 2a were, respectively, 100 vs. 95%, and 85 vs. 80%. There was no statistical significance in the recurrent hemorrhage rate, reintervention rate, or 30 day mortality between targeted and empiric embolization groups. There were no complications attributed to embolization within this study cohort.
Cases of duodenal-related major upper gastrointestinal hemorrhage where no embolization is performed have poor outcome. Empiric embolization of the GDA in patients with major upper gastrointestinal hemorrhage refractory to endoscopic treatment appears to be a safe and effective treatment, with low reintervention rates and good clinical outcome comparable to patients where the site of hemorrhage is localized and embolized with computed tomographic angiography or catheter angiography and embolized.
评估经验性胃十二指肠动脉(GDA)栓塞在减少复发性出血方面相对于基于影像的靶向栓塞的相对疗效。
回顾性收集 2008 年 5 月至 2010 年 11 月期间因上消化道大出血而行导管血管造影的连续患者的数据(n=40)。根据血管造影结果将总病例数分为两组:在导管血管造影上显示出血部位的患者(组 1,n=13)和在导管血管造影上未识别出血部位的患者(组 2,n=27)。然后将组 2 进一步分为接受经验性栓塞的患者(组 2a,n=20)和血管造影后未进行栓塞的患者(组 2b,n=7)。
组 1 和组 2a 的栓塞技术和临床成功率分别为 100%对 95%,85%对 80%。在复发性出血率、再介入率或 30 天死亡率方面,靶向和经验性栓塞组之间没有统计学意义。在本研究队列中,没有归因于栓塞的并发症。
对于未进行栓塞的十二指肠相关上消化道大出血病例,预后不佳。对于内镜治疗无效的上消化道大出血患者,经验性 GDA 栓塞似乎是一种安全有效的治疗方法,再介入率低,临床结果良好,与出血部位定位并通过 CT 血管造影或导管血管造影栓塞并栓塞的患者相当。
