Liver transplantation in the presence of portal vein thrombosis: Report from a single center

Portal vein thrombosis (PVT) is a frequent finding in liver transplantation, the management of which depends mainly on its extent. In cases of mild to moderate PVT, a low dissection of the portal trunk, a jump graft, or direct implantation of graft portal vein into large venous collaterals or thrombectomy offer alternatives. For severe PVT anecdotal reports suggest that cavoportal hemitransposition, portal arterialization, or combined liver and intestine transplantation may be attempted, although the results to date are not satisfactory. When extensive perivenous and venous inflammatory changes reach the infrapancreatic region, liver transplantation probably should not be performed due to the high mortality rate

Massive anterior chamber involvement in advanced retinoblastoma following intra-arterial chemotherapy

Purpose to describe retinoblastoma massive anterior chamber involvement after treatment with intra-arterial chemotherapy. This condition represents an extremely poor prognostic sign for ocular preservation in patients with retinoblastoma. Therefore, anterior chamber retinoblastoma should be considered an absolute indication for enucleation. Methods Ultrasound biomicroscopy (UBM) was used to document tumour pseudohypopion, cells in the aqueous humor, implanted clusters of cells on the corneal endothelium, iris nodules and lens capsule deposits. Results The UBM data were compared with the histopathologic analysis after enucleation and revealed a significant concordance. Conclusion UBM may represent an important diagnostic tool in retinoblastoma, particularly when the decision about enucleation of the eye, must be made in the absence of histopathologic data

Interposition of the right colic angle between the liver and thoracic wall: An unusual cause of massive rectal bleeding following percutaneous biopsy in a liver transplant recipient

A 37-year-old male liver transplant recipient developed hemorrhagic shock from massive rectal bleeding a few hours after a protocol liver biopsy. Conservative treatment was not possible and the patient underwent a radiological investigation of the celiac and mesenteric arterial trunks, which showed active bleeding from a branch of the middle colic artery. Embolization with Tabotamp (Ethicon, Neuchatel, CH Switzerland) particles led to successful hemostasis. We thus discuss the possible mechanisms of injury. To our knowledge, no other cases of major rectal bleeding following percutaneous liver biopsy have been reported in the literature. We emphasize the need for Doppler ultrasound assistance, in terms of either preoperative examination with or without marking or guidance. The latter is the safest and most reliable technique, given the low risk of puncture of other organs and the low probability of obtaining an inadequate sample
