The prevalence of non-alcoholic fatty liver disease (NAFLD), now referred to as metabolic dysfunction-associated steatotic liver disease (MASLD), is rising, especially among patients undergoing liver surgery (hepatectomy) due to liver cancer.
A study of 106 hepatectomy patients found that those with MASLD had a significantly higher incidence of post-hepatectomy portal vein thrombosis (PH-PVT) compared to those without steatosis.
MASLD and its variant associated with moderate alcohol consumption (MetALD) were identified as major risk factors for PH-PVT, suggesting that metabolic dysfunction plays a critical role in thrombosis risk post-surgery.
