Postmortem angiography was used as a diagnostic tool to rule out surgical malpractice in 227 medicolegal autopsies following postoperative deaths in Finland. Of the cases, 111 involved neurosurgical patients or patients undergoing operations on the carotid arteries, 62 involved coronary bypass patients, and 54 patients died following abdominal surgery. A portable perfusion device for postmortem angiography at the autopsy table involves attaching quick couplings to a compressed airline. Permanent cast and three-dimensional topographic assessment of vascular anatomy are achieved using solidifying silicone rubber with lead oxide as a contrast medium and stereopair radiographs. This technique can be performed by experienced autopsy technicians and can be linked to normal autopsy services. In our experience, postmortem angiography is useful in investigating all complicated deaths following surgical operations.
