Abstract:
Objective To evaluate spiral CT in diagnosing vascular complications of pancreatitis. Methods The clinical and surgical results and the CT findings of 316 patients with acute or chronic pancreatitis were comparatively analyzed. Special attention was paid to the CT findings of the patients with peritoneal hemorrhage and vascular abnormality. CT Hu of celiac blood effusion was measured. Pseudoaneurysms, phlebothrombosis and venous thrombosis of peripancreatic vessels in CT enhancement were carefully analyzed. Results Acute pancreatitis was found in 275 out of the 316 patients, and chronic pancreatitis in 41 cases. Among those with acute pancreatitis, 20 had peritoneal cavity vascular complications. In the 13 cases of peritoneal cavity hemorrhage(including 5 patients complicated with digestive tract hemorrhage), CT identified 11 with as regional or diffuse slight high density fluid collections, and failed in 2 cases. CT scans detected gastric varices in 4 out of 7 patients with digestive tract hemorrhage. Of those with chronic pancreatitis, CT found celiac artery pseudoaneurysm in one, spleen artery pseudoaneurysm in one and splenic vein thrombosis with gastric varices in one. Conclusions (1)Regional or diffuse slight high or high density fluid collections were common CT findings of peritoneal cavity hemorrhage. (2)Enhanced spiral CT scanning could demonstrate peripanreatic vascular pseudoaneurysms. (3)Varices in gastric fundus and necrosis in pancreatic body and tail often indicate the formation of spleen venous thrombosis.
