OBJECTIVES: We aimed to present our experience regarding the unusual vascular complications and specific treatment strategies in patients who underwent transradial coronary procedure (TRC). BACKGROUND: Transradial access provides lower vascular access site complication rates compared with transfemoral access. However, there is lack of data obtained from large study populations concerning the incidence and treatment strategies of hemorrhagic and vascular complications following a TRC in the literature. METHODS: 10,324 patients (2,652 patients with percutaneous coronary intervention and 7,672 patients with a diagnostic transradial coronary angiography) who underwent a TRC from February 2010 to December 2014 were reviewed to identify cases of large hematoma, perforation, arteriovenous fistula, and pseudoaneurysm. RESULTS: The observed incidence was 0.44% (45 patients) for all unusual vascular and hemorrhagic complications. Of these 45 patients; 32 patients (0.31%) presented with large hematoma (≥6 cm), 8 patients (0.08%) presented with perforation, 4 patients (0.04%) presented with arteriovenous fistula (AVF), and only 1 case (0.009%) presented with radial artery pseudoaneurysm. Forty-one of forty-five patients were managed with mechanical compression. Surgery was performed in only 3 cases; a patient with a brachial artery perforation leading to compartment syndrome, a patient with AVF resulting in limb ischemia, and a patient with radial artery pseudoaneurysm. A right internal mammarian artery perforation resulting in huge breast hematoma was treated via endovascular graft stent implantation. CONCLUSIONS: Hemorrhagic and vascular complications are rarely seen during TRC. However, majority of these complications could be managed conservatively without a requirement for surgical reconstruction.
