Giant thoracic hematoma post-transradial coronary angiography: a case report and review of the literature.

ABSTRACT

BACKGROUND: Although there are cardiac interventional procedures, certain transradial access complications might be life-threatening. CASE PRESENTATION A 67-year-old male was admitted for coronary angiography due to chest tightness and shortness of breath on exertion. Hours after the right transradial access angiography, the patients complained the right side of chest pain. Emergent chest X-ray revealed a giant mass in the right chest. The right radial artery was reaccessed and subsequent arteriograms confirmed that the presence of a rupture of the branch of right internal mammary artery. Simultaneously, a microcoil was implanted to seal the perforation. The perforation caused a thoracic hematoma measuring 13.8 cm × 6.7 cm, along with a decrease in hemoglobin concentration from 14.1 g/dL to a minimum of 7.8 g/dL. Additionally, the drainage of the hematoma and red blood cells transfusion were carried out. Further, the patient underwent ascending aortic replacement, aortic valve replacement, mitral valve replacement, and thoracic hematoma removal. Postoperative echocardiography showed that the prosthetic valves were properly positioned and functioning normally. The patient recovered well after the surgery and remained event-free during the latest 14moth follow-up period. CONCLUSIONS: Vascular perforation and subsequent hematoma might occur due to guidewire maneuvering during transradial approach. Awareness of prevention, early recognition and management of access complications may help reduce the occurrence and severity of complications related to the transradial approach.
