以往认为急性胰腺炎的起始损害因素是酶,现在许多证据表明缺血是胰腺坏死的始发或加重因素。应用造影剂加强 CT 动态观察人体和动物急性胰腺炎早期微循环灌注减少与胰腺炎的严重程度密切相关,在坏死区域尤为显著。在临床上重症胰腺炎早期表现为低血压,而应用α-肾上腺素类血管收缩剂以维持血 In the past that the initial cause of acute pancreatitis damage factor is enzyme, and now there is much evidence that ischemia is the origin or aggravating factor of pancreatic necrosis. Contrast agents to enhance CT dynamic observation of human and animal acute pancreatitis Reduction of early microcirculation perfusion and severity of pancreatitis are closely related, especially in the necrotic area. Serious pancreatitis in the early clinical manifestations of hypotension, and the application of α-adrenergic vasoconstrictor to maintain blood
