Abstract

Arteriography remains the definitive radiologic procedure for diagnosing complications of vascular prosthetic grafting. Gray scale B-mode ultrasonography is well suited for detection of false aneurysms, abscesses, and hematomas. The gastrointestinal series is of limited value in assessing most grafts. In non emergent cases, excretory urography may provide useful diagnostic information as well as determine the location of the kidneys and ureters preoperatively. Computed tomography may aid in demonstrating and following the course of postoperative hematomas; it may also be valuable in demonstrating periprosthetic abscess. A strategy is suggested for selecting the appropriate method of evaluating vascular prosthetic grafts.

摘要

动脉造影术仍然是诊断血管移植并发症的决定性放射学检查方法。B 型灰阶超声检查非常适合检测假性动脉瘤、脓肿和血肿。胃肠道造影在评估大多数移植血管时价值有限。在非紧急情况下，排泄性尿路造影不仅可以提供有用的诊断信息，还可以在术前确定肾脏和输尿管的位置。计算机断层扫描有助于显示和追踪术后血肿的病程；在显示假体周围脓肿方面也可能有价值。本文提出了一种选择评估血管移植合适方法的策略。
