胰周假性动脉瘤(peripancreatic pseudoaneurysms,PPA)~([1])指起源于腹腔动脉和肠系膜上动脉及其分支、位于胰腺周围的假性动脉瘤,其主要病因为胰腺炎发病时含有多种胰酶的胰腺渗出液及胰腺炎性反应浸润可直接侵蚀胰周血管,导致胰周动脉壁腐蚀破坏导致假性动脉瘤形成甚至引起大出血。文献~([2-3])报道,胰腺假性囊肿中血管合并症发生率可达到7%~10%,急性胰腺炎(acute pancreatitis,AP)的血管合并症发生率约为1%~6%。临床相对少见,病情复杂,
Peripancreatic pseudoaneurysms (PPA) ~ ([1]) refers to the pseudo-aneurysms originating from the celiac and superior mesenteric arteries and their branches located around the pancreas. The main cause of this disease is the presence of more Pancreatic excretion of pancreatic enzymes and pancreatic inflammatory infiltration can directly erode the peripancreatic vessels, resulting in corrosive destruction of the peripancreatic artery wall resulting in the formation of pseudoaneurysm and even causing major bleeding. The literature ~ ([2-3]) reported that the incidence of vascular complications in pancreatic pseudocysts can reach 7% to 10%, the incidence of vascular complications of acute pancreatitis (AP) is about 1% to 6 %. Relatively rare clinical, complex condition,
