胰腺炎可侵及脾脏血管,使脾动脉坏死引起致死性出血。使脾静脉阻塞形成局部门脉高压。局部脾门静脉高压使胃底静脉曲张、出血,胃短静脉及腹膜后脾系静脉侧枝扩张,食道下段静脉曲张,而大网膜及肠系膜静脉正常。由于脾的大血管解剖位置易被胰体及胰尾的炎症所侵犯、形成假囊肿及脾静脉阻塞。假囊肿可腐蚀脾动脉,也可直接腐蚀脾被膜引起粘连后由小的外伤即可造成脾撕裂出血。
Pancreatitis can invade the spleen and blood vessels, causing necrosis of the splenic artery to cause bleeding. The spleen veins blocked the formation of local portal hypertension. Local splenic portal hypertension to gastric varices, bleeding, short-venous and retroperitoneal splenic venous collateral dilatation, esophageal varicose veins, and the omental and mesenteric vein normal. Due to the large splenic anatomical location of the pancreas and pancreatic tail inflammation easily infringement, the formation of pseudocyst and splenic vein occlusion. False cysts can corrode the splenic artery, can also be directly corrosive spleen capsule caused by adhesions by a small trauma can cause tearing of the spleen.
