ABSTRACT

Objective:

To study the risk factors of early postoperative portal vein thrombosis (PVT) after salvage devascularization for failed endoscopic therapy.

Methods:

A retrospective analysis was conducted on the clinical data of 525 cirrhotic patients who underwent pericardial devascularization for portal hypertension and esophagogastric variceal bleeding at the Department of General Surgery, Beijing Ditan Hospital, Capital Medical University from January 2012 to January 2022. There were 435 males and 90 females, aged 47(37, 58) years old. These patients were divided into two groups based on whether PVT occurred after devascularization the PVT group ( n=225) and the non-PVT group ( n=300). Clinical data including gender, age, portal vein diameter and postoperative platelet elevation level (PPEL) were studied and the related factors of PVT were analyzed by univariate analysis. Factors with statistically significant differences were included in logistic regression analysis.

Results:

Univariate analysis showed that the significant risk factors of PVT were the scores of the model of end-stage liver disease, platelets, portal vein diameter, endoscopic therapy, operation duration, surgical bleeding volume, intraoperative blood transfusion and PPEL on the first and third postoperative days (all P<0.05). Multivariate analysis showed that portal vein diameter ≥13 mm ( OR=6.000, 95% CI 3.418-10.533), endoscopic injection ( OR=1.894, 95% CI 1.196-2.998), operation duration ≥ 180 min ( OR=8.520, 95% CI 5.333-13.554), PPEL ≥ 20×10 9/L on the first postoperative day ( OR=2.125, 95% CI 1.306-3.456) and PPEL≥50×10 9/L on the third postoperative day ( OR=1.925, 95% CI 1.192-3.109) increased the risk of PVT (all P<0.05).

Conclusion:

The diameter of portal vein, endoscopic treatment, operation duration and PPEL on the first and third days after operation were independent risk factors of early postoperative PVT development.
