Abstract

Continuous Ambulatory Peritoneal Dialysis (CAPD) is a common method of treatment for patients with renal failure. Complications however are frequent and often force the abandonment of this form of treatment. The radiological evaluation of these complications is important as it can modify the subsequent treatment. Using conventional CT techniques it is often difficult to differentiate loculated intra-peritoneal collections from residual dialysis fluid. It may also be difficult to demonstrate the site of leakage into the extra-peritoneal structures. The use of CT peritoneography (CTP) provides a method of improving diagnosis in these patients. Hypodense intra-peritoneal collections are readily appreciated against a background of hyperdense dialysis fluid. Sites of leakage into the extra-peritoneal soft tissues can likewise be rapidly identified. The abnormalities detected in this series include a pelvic abscess, and leakage down the inguinal canal, around the Tenckhoff catheter and through the anterior abdominal wall. CTP is recommended as the examination of choice in dialysis patients with suspected leaks or collections. The findings aid in planning subsequent surgical treatment and prevent unnecessary surgical exploration.

腹膜透析患者的CT腹膜造影。
连续动态腹膜透析(CAPD)是治疗肾功能衰竭患者的常用方法。然而,并发症是频繁的,往往迫使放弃这种形式的治疗。这些并发症的放射学评估很重要,因为它可以改变后续的治疗。使用传统的CT技术通常很难区分腹膜内积液和残留的透析液。也可能难以确定渗漏到腹膜外结构的部位。使用CT腹膜造影(CTP)提供了一种提高诊断的方法。低密度的腹膜内积液在高密度透析液的背景下很容易被识别。渗漏到腹膜外软组织的部位同样可以快速识别。在本系列中发现的异常包括盆腔脓肿,腹股沟管,Tenckhoff导管周围和前腹壁渗漏。CTP被推荐作为怀疑有渗漏或收集的透析患者的首选检查。结果有助于规划后续手术治疗,防止不必要的手术探查。
