Peritoneal Scintigraphy for Diagnosing Periumbilical Leakage in a Patient on Continuous Ambulatory Peritoneal Dialysis

腹膜閃爍攝影於連續性腹膜透析患者的透析液在肚擠周圍滲漏的診斷價值:病例報告

摘要


對於末期腎臟疾病患者連續性腹膜透析提供許多勝於血液透析的優點,但有許多併發症也曾被發現過。此案例因為臨床上懷疑透析液滲漏,而接受鎝-99m macroaggregated human albumin(99mTc-MAA)腹膜閃爍攝影的檢查。在腹膜內灌注99mTc-MAA 2小時30分鐘後,方偵測到肚擠周圍有放射性同位素活性增加;而6小時的影像則顯示在同一處有更明顯的放射性同位素活性增加。本篇報告顯示藉由腹膜閃爍攝影此種簡易、安全的技術可以正確診斷出透析液於肚擠周圍的滲漏。

Continuous ambulatory peritoneal dialysis (CAPD) offers several advantages over hemodialysis for patients with end-stage renal disease; however, this technique also includes many documented complications. A case with clinical suspicion of dialysate leakage on CAPD was investigated by peritoneal scintigraphy using technetium-99m macroaggregated human albumin (99mTc-MAA). Peritoneal scintigraphy showed radiotracer accumulation over the periumbilical area at 2 hours 30 minutes after intraperitoneal infusion of 99mTc-MAA. Six hours of imaging revealed more apparent radioactivity at the same site. This study is to illustrate the simple diagnostic helpfulness of peritoneal scintigraphy in a patient with a CAPD-related structural defect.
