Femoral Artery Pseudoaneurysm and Sudden Death
Abstract: Pseudoaneurysm formation may be a late complication of vascular grafting. A case of sudden death in an 83‐year‐old woman with a previous aortobifemoral bypass graft is reported that was due to spontaneous hemorrhage from a pseudoaneurysm of the graft
site that had eroded through the overlying skin and subcutaneous tissues. Pseudoaneuryms do not have to be of a particularly large size for rupture to occur. Social isolation and age‐related cognitive impairment may delay treatment in older individuals resulting in a lethal outcome.
The elderly are also more vulnerable to serious morbidity and death under these circumstances owing to significant underlying cardiovascular and respiratory disease and/or anticoagulant medication. Rarer conditions that may cause pseudoaneurysms include tumors and vasculidites. The possibility
of an infectious contribution to the pseudoaneurysm should be considered and microbiological sampling undertaken.
