Résumé
Portal vein thrombosis (PVT) is no longer an absolute contraindication for living donor liver transplantation (LDLT). This study aimed to assess the short-term outcomes of LDLT and compare the 1-year survival rates between patients with and without preoperative PVT. This combined prospective and retrospective cohort study was conducted on patients who underwent LDLT at Ain Shams Centre for Organ Transplantation (ASCOT) between 2008 and 2020. The study included 60 patients with PVT and 60 patients without PVT. The two groups were compared in terms of preoperative data, operative details, postoperative complications, and 1-year survival. Most patients with PVT were Child C (65%) and had higher model for end stage liver disease scores (16.23 ± 4.03) compared to the non-PVT group (13.9 ± 4.5). The PVT group showed longer cold ischemic time (CIT), hospital stay, and intensive care unit stay and significantly shorter 1-year survival rate (63.3%) compared to the non-PVT group (86.7%) (P = 0.003). Those with PVT grades I, II, and III had 1-year survival rates of 72.5%, 50%, and 40%, respectively. Preoperative PVT reduces the 1-year survival after transplantation, with patients with higher PVT grades exhibiting lower 1-year survival. LDLT for PVT still remains challenging and requires further studies.

BACKGROUND AND STUDY AIMS
OBJECTIVE
Portal vein thrombosis (PVT) is no longer an absolute contraindication for living donor liver transplantation (LDLT). This study aimed to assess the short-term outcomes of LDLT and compare the 1-year survival rates between patients with and without preoperative PVT.
PATIENTS AND METHODS
METHODS
This combined prospective and retrospective cohort study was conducted on patients who underwent LDLT at Ain Shams Centre for Organ Transplantation (ASCOT) between 2008 and 2020. The study included 60 patients with PVT and 60 patients without PVT. The two groups were compared in terms of preoperative data, operative details, postoperative complications, and 1-year survival.
RESULTS
RESULTS
Most patients with PVT were Child C (65%) and had higher model for end stage liver disease scores (16.23 ± 4.03) compared to the non-PVT group (13.9 ± 4.5). The PVT group showed longer cold ischemic time (CIT), hospital stay, and intensive care unit stay and significantly shorter 1-year survival rate (63.3%) compared to the non-PVT group (86.7%) (P = 0.003). Those with PVT grades I, II, and III had 1-year survival rates of 72.5%, 50%, and 40%, respectively.
CONCLUSION
CONCLUSIONS
Preoperative PVT reduces the 1-year survival after transplantation, with patients with higher PVT grades exhibiting lower 1-year survival. LDLT for PVT still remains challenging and requires further studies.
