Radial artery pseudoaneurisma due to unintentional arterial puncture during cephalic vein cannulation: A rare case report

INTRODUCTION AND IMPORTANCE: Radial artery pseudoaneurysm is considered as an extremely rare and serious complication that usually follows after cardiac catheterizations with incidence of less than 0.05%, but in lesser frequency with arterial cannulation, trauma, and inflammation or hemodialysis therapy. On the other hand, venous access is clinically important, as it allows for blood sampling, administration of medications, fluids, nutrition, and chemotherapy. But its usage is associated with complications like catheter-associated infections, injuries to peripheral nerves, along with thrombosis and phlebitis of the vessel involved as well as arterial injury. CLINICAL PRESENTATION: in this report, we present a 67 years old healthy nonsmoker male patient with proximal radial artery pseudoaneurysm following several attempts of cephalic vein cannulation for intravenous access. CLINICAL DISCUSSION: Radial artery pseudo-aneurisms are very rare with reported incidence of 0.048%, and mainly due to arterial puncture in an attempt of cardiac intervention procedures, but to the authors knowledge this is one of the first reported cases of radial artery pseudoaneurysm caused by arterial puncture in an attempt of cephalic vein cannulation. CONCLUSION: Radial artery pseudoaneurysm can occur after attempts of cephalic vein cannulation and patients can be successfully managed with surgical removal of the false aneurism and radial arteriorrhaphy.
