Bleeding varicose veins’ ulcer as a cause of death. A case report and review of the current literature

Chronic venous insufficiency (CVI) and varicose veins (VVs) of the lower limbs are very frequent vascular diseases in Western countries. One possible complication of these conditions is skin ulceration and its consequent rupture, which can be spontaneous or due to mild or trivial trauma. In some cases, the resulting hemorrhage is fatal. When the victim is found dead, a large amount of blood around the body might lead to the hypothesis of violent death. The Forensic Pathologist needs to be very careful in the corpse’s examination, in order to exclude any alternative cause of death. Herein, an illustrative case is reported, as well as a literature review of the literature concerning sudden hemorrhages from VVs. We found 27 scientific papers, the total reported cases of VVs rupture with profuse hemorrhages were 36, 32 of which were fatal. The main characteristics of such forensic scenario have been collected. Corpse examination of the victims showed pallor of the skin and mucous membranes, as well as marked pallor of organs as a sign of hemorrhagic shock, but these pathological findings are unspecific. Usually, the skin near the ulcer presented color alteration (discoloration and atrophy or pigmentation and hyperemia). Besides, the histological examination of the skin could be a valid instrument to demonstrate the presence of the ulcer, even if it could be very difficult to sample, because of its small size. An important limit of our study is the small number of collected cases. More studies in this field are needed to improve evidence concerning death due to VVs rupture.
