RESUMO
Varicose veins (VVs) and varicose ulceration (VU) are usually considered non-life-threatening conditions, but in some cases they can lead to major complications such as fatal bleeding. The aim of this systematic review is to evidence the most updated information on bleeding from VV and VU. As evidence acquisition, we planned to include all the studies dealing with "Haemorrhage/Bleeding" and "VVs/VU". We excluded all the studies, which did not properly fit our research question, and with insufficient data. As evidence synthesis, of the 172 records found, after removing of duplicates, and after records excluded in title and abstract, 85 matched our inclusion criteria. After reading the full-text articles, we decided to exclude 68 articles because of the following reasons: (1) not responding properly to our research questions; (2) insufficient data; the final set included 17 articles. From literature searching, we identify the following main issues to be discussed in the review: epidemiology and predisposing factors, pathophysiology and forensic aspects, first aid. It has been estimated that deaths for bleeding due to peripheral venous problems account up to 0.01% of autopsy cases. From a pathological point of view, venous bleeding may arise from either acute or chronic perforation of an enlarged vein segment through the weakened skin. From a forensic point of view, in cases of fatal haemorrhage the death scene can even simulate non-natural events, due to crime or suicide. In most cases, incorrect first aid led to fatal complications. Further investigation on epidemiology and prevention measures are needed.
