Fluid Flow Patterns Through Drainage Catheters: Clinical Observations in 99 Patients.

Purpose: To describe patterns of fluid flow through locking pigtail and biliary catheters in patients that underwent biliary and abdominopelvic fluid drainage.

Methods: Contrast movement through catheter sideholes in pigtail and biliary catheters was evaluated retrospectively using sinograms and cholangiograms at 7-10 days post insertion. Dilute contrast injected through the catheter was evaluated by following flow through the catheter shaft and exit from side holes within the body cavity.

Ethanol ablation in postbiopsy liver hemorrhage following two failed embolizations.

A 42-year-old male presented with intraperitoneal hemorrhage 5days following percutaneous liver biopsy for suspected hepatocellular carcinoma. Diagnostic angiogram localized the bleeding to segment VI hepatic artery branches. Two consecutive arterial embolizations with microspheres and platinum coils failed to control the bleeding.
