Passing loop technique for portal inflow modulation in liver recipients with partial portal vein thrombosis: a case report.

Refinements of surgical techniques in liver transplant during the last 10 years have offered more successful outcomes for recipients with portal vein thrombosis. Patency of the portal vein after a thrombectomy can be neither adequately evaluated, nor objectively assessed; therefore, we suggest that rerouting part of the portal flow through a "passing loop," with or without augmenting the portal flow, may be a salvage procedure, when there is a possible postoperative rethrombosis of the portal vein.
