Thrombofibrinous sheath occlusion of peritoneovenous shunts.
Thrombofibrinous sheath occlusion of peritoneovenous shunts is described in two case presentations. In reviewing the literature, we found only 17 other such cases mentioned. Most patients were seen initially with recurrence of ascites and only one with superior vena cava syndrome. A shuntogram documented a characteristic sheath in 17 patients, and relocation was the preferred treatment. Relocation was successful in eight of 11 attempts, but long-term follow-up data were not available. Histologic examination of the sheath in our first case study revealed recent and organized thrombus. This would help explain why only one of three patients was successfully treated with fibrinolytic agents.
