Death during percutaneous transluminal coronary angioplasty (PTCA) and the medicolegal aspects.
Coronary embolisation is a very rare complication of the clinically widespread method of percutaneous transluminal coronary angioplasty (PTCA). The well-documented case of a 64-year-old male patient is presented comparing angiographic and morphological findings. The occluded left anterior descending artery (LAD) was successfully dilated during PTCA. Simultaneously the circumflex artery showed acute occlusion. The patient fell into cardiac shock and died after attempted resuscitation and agonal installation of extracorporeal circulation. The autopsy revealed severe residual stenosis of the proximal LAD by parietal thrombosis and occlusion of the proximal circumflex artery by an unattached intraluminal thrombus (0.8 x 0.3 x 0.2 cm) which had been dislocated during PTCA. Autopsy thus confirmed the clinical presumption of coronary embolism and, in addition, disclosed a previously unknown perforation of the femoral artery which had occurred during agonal installation of extracorporeal circulation and contributed to death via severe retroperitoneal hemorrhage. The case is discussed under the aspects of clinical quality control by forensic pathological investigations.
