Abstract
The diagnostic and preoperative localization of the pancreatic insulinoma is shown using the method of digital subtraction angiography (DSA). Insulinoma are very rare pancreatic tumors, hormonally active, in more than 90% benign. In size they rarely excede 2 cm in diameter. Usually they are solitary and do not have predictable site in the pancreas. With a correct diagnostic and preoperative localization of an insulinoma we can achieve good therapeutic results which reduce the possibility of potential postoperative complications. We had six patients, three men and three women. On the basis of their clinical symptoms, biochemical findings and anamnesis pancreatic insulinoma was spected. We performed digital subtraction angiography and found small hypervascular tumors which were separated from the rest of the healthy pancreatic tissue. Three of the tumors were localized in the caput and three in the corpus of the pancreas. Five of them were vascularized from truncus coeliacus and one from a. mesenterica sup. We operated and removed the tumors and the diagnosis was confirmed by the histopathological analysis. Digital subtraction angiography has proven as a very sensitive method in the diagnostic and preoperative localization of pancreatic insulinoma. There was no sign of hyperinsulinism in any of our patients, which was confirmed by later examinations.
