Recipient hepatectomy is a challenging liver transplantation (LT) procedure that has life-threatening complications. The current predictive mortality clinic-biological scores (Child/MELD) do not take into consideration the recipient liver anatomy. The aim of this study was to evaluate the impact of the dorsal sector anatomy of a cirrhotic liver on the morbidity/mortality rates of hepatectomy.
A multicenter retrospective study (clinic-biological and morphologic) was performed from 2013 to 2014. The degree of encirclement of the inferior vena cava (IVC) by the dorsal sector of the liver was measured.
The study population included 320 patients. Seventy-four (23%) patients had complete IVC encirclement. A correlation (p=0.01) has been reported between the existence of a circular dorsal sector and the number of transfusions during LT (4 PRC in the group without IVC vs 7 PRC in the other group). The existence of such anatomy increases the relative risk of early reoperation for IVC bleeding by 31% (p= 0.05). There is a correlation between alcoholic cirrhosis and dorsal-sector hypertrophy (126 cc vs 147.5 cc, p=0.05). Concerning surgical time, we found no significant between-group differences. Compared to the severity of cirrhosis, an inverse correlation was observed between the MELD and Child scores and the dorsal sector hypertrophy (p=<0.001). No significant difference in terms of transfusion was found between the temporary portocaval shunt group (n=168) and the other group (n=152).
The presence of a circular sector is associated with an increased risk of hemorrhage during hepatectomy, as well as an immediate postoperative risk of reoperation. This article is protected by copyright. All rights reserved.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 May 2016.
All research outputs
#22,758,309
of 25,371,288 outputs
Outputs from Liver Transplantation
#2,100
of 2,322 outputs
Outputs of similar age
#323,538
of 367,255 outputs
Outputs of similar age from Liver Transplantation
#26
of 45 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,322 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 367,255 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 45 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
