Background. Gastrointestinal bleeding (GIB) after a vascular surgery operation is a severe complication which encourages further investigation and enquiry into the possibility of finding reversible risk factors.
Material and methods. Elective treatment was carried out on 741 patients. There were no statistical differences in the occurrence of the complication of gastrointestinal bleeding between the endovascular (173) and surgical procedures (568). The type of analysis was prospective and not randomized.
Results. We noticed 14 cases (1.89%) of gastrointestinal bleeding (GIB). We distinguished three independent risk factors that contributed towards the likelihood of GIB. These factors were kidney impairment (p < 0.005), leukocytosis (p < 0.005), and a past medical history of gastric ulcer (p < 0.005). Moreover, chronic diseases like angina, diabetes, circulatory insufficiency, and the final stages of chronic limb ischemia might increase the risk of gastrointestinal bleeding.
Conclusions. Past medical history of gastric ulcer disease, impairment of kidney function, and inflammation are related to an increased risk of gastrointestinal bleeding after surgical reconstruction of peripheral arteries.
