A case of portal vein and superior mesenteric vein thrombosis associated with acute cholecystitis

Portal and superior mesenteric vein thrombosis (PMVT) may occur, rarely though, secondary to hypercoagulable states, cirrhosis with portal hypertension, pancreatitis, peritonitis, inflammatory bowel disease and intraabdominal abscess. However, PMVT induced by acute acalculous cholecystitis has not been reported yet. We recently experienced a case of acute acalculous cholecystitis complicating PMVT. A 38-year-old male was admitted for RUQ pain, chill and fever without any previous medical history in particular and diagnosed as acute acalculous cholecystitis and PMVT. The diagnosis of PMVT secondary to acute acalculous cholecystitis was possible since there was no other cause of thrombosis. This patient's condition was improved without any complication after cholecystectomy and anticoagulant regimen. Thus, we report a case of PMVT secondary to acute acalculous cholecystitis for the first time in Korea.
