Intrahepatic biliary anatomy derived from right graft adult live donor liver transplantation

2008

Abstract Objective The successful management of the bile duct in right graft adult live donor liver transplantation requires knowledge of both its central (hilar) and distal (sectorial) anatomy. The purpose of this study was to provide a systematic classification of its branching patterns to enhance clinical decision-making. Patients and Methods We analyzed three-dimensional computed tomography (3-D CT) imaging reconstructions of 139 potential live liver donors evaluated at our institution between January 2003 and June 2007. Results Fifty-four (n = 54 or 38.8%) donor candidates had a normal (classic) hilar and sectorial right bile duct anatomy (type I). Seventy-eight (n = 78 or 56.1%) cases…

Hepatic Hilar and Sectorial Vascular and Biliary Anatomy in Right Graft Adult Live Liver Donor Transplantation

2008

Abstract Introduction The aim of this study was to analyze vascular and biliary variants at the hilar and sectorial level in right graft adult living donor liver transplantation. Methods From January 2003 to June 2007, 139 consecutive live liver donors underwent three-dimensional computed tomography (3-D CT) reconstructions and virtual 3-D liver partitioning. We evaluated the portal (PV), arterial (HA), and biliary (BD) anatomy. Results The hilar and sectorial biliary/vascular anatomy was predominantly normal (70%–85% and 67%–78%, respectively). BD and HA showed an equal incidence (30%) of hilar anomalies. BD and PV had a nearly identical incidence of sectorial abnormalities (64.7% and 66.2…

A New Systematic Classification of Peripheral Anatomy of the Right Hepatic Duct: Experience From Adult Live Liver Donor Transplantation

2008

Abstract Objective The peripheral intrahepatic biliary anatomy, especially at the sectorial level on the right side, has not been adequately described. The purpose of our study was to systematically describe this complex anatomy in clinically applicable fashion. Patients and Methods We analyzed three-dimensional computed tomography (CT) imaging reconstructions of 139 potential living liver donors evaluated at our institution between January 2003 and June 2007. Results Eighty-nine (64%) donors had a normal right bile duct sectorial anatomy. In the other 50/139 (36%) cases, we observed abnormal sectorial branching patterns, with 45/50 abnormalities as trifurcations, whereas the remaining ones…

Different guidelines for imaging after first UTI in febrile infants: yield, cost, and radiation.

2013

OBJECTIVE: To evaluate the yield, economic, and radiation costs of 5 diagnostic algorithms compared with a protocol where all tests are performed (ultrasonography scan, cystography, and late technetium99dimercaptosuccinic acid scan) in children after the first febrile urinary tract infections. METHODS: A total of 304 children, 2 to 36 months of age, who completed the diagnostic follow-up (ultrasonography, cystourethrography, and acute and late technetium99dimercaptosuccinic acid scans) of a randomized controlled trial (Italian Renal Infection Study 1) were eligible. The guidelines applied to this cohort in a retrospective simulation were: Melbourne Royal Children’s Hospital, National Insti…

Anatomical Classification of the Peripheral Right Hepatic Duct: Early Identification of a Preventable Source of Morbidity and Mortality in Adult Live…

2008

Abstract Introduction The purpose of this study was to determine the impact of our classification on right graft adult live donor liver transplantation (ALDLT) outcomes. Methods Three-dimensional computed tomography (CT) reconstructions were used to classify the hilar and sectorial biliary anatomy of 71 consecutive live liver donors. Four possible clinical types were defined, based on the normal (N) or abnormal (A) features of the corresponding hilar/sectorial ducts: type I, N/N; type II, N/A; type III, A/N; and type IV, A/A. We subsequently performed an analysis of the operative outcomes based on the donor anatomy. Results Type I was encountered in 47.9% of cases, type II in 29.6%, type II…
