Acute Hand Ischemia and Digital Amputation After Transradial Coronary Intervention in a Patient With CREST Syndrome.

The radial artery approach for coronary angiography and intervention is rapidly replacing the femoral artery approach, largely because it reduces bleeding and vascular access site complications. However, complications associated with transradial access warrant attention, notably radial artery occlusion. This report focuses on a case of radial artery occlusion after percutaneous coronary intervention in a 46-year-old woman with CREST (calcinosis, Raynaud phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasia) syndrome, which ultimately led to acute hand ischemia necessitating amputation of her middle and index fingers.
