Inadvertent subclavian artery cannulation treated by percutaneous closure

Abstract

Accidental arterial puncture occurs in around 1% and 2.7% of jugular and subclavian approaches, respectively. When a line has been inadvertently inserted into an artery at a noncompressible site, there is an increased risk for serious complications. This complication can be treated by either surgical or endovascular intervention or a combination; however, in critically ill patients or in those with impaired coagulation, therapeutic options are more limited. We describe successful endovascular management of inadvertent subclavian artery cannulation during insertion of a triple lumen central line catheter in a 35-year-old man suffering from leukemia, with sepsis and multi-organ failure. He was hypotensive and hemodynamically unstable, with severe coagulopathy. The catheter had entered the artery at the level of the origin of the internal mammary artery, just above the origin of the vertebral artery. The tip was lying in the aortic arch. The artery was successfully closed by endovascular deployment of an 8 French Angio-Seal device (St. Jude Medical, St. Paul, MN, USA). The device is licensed for use in femoral arterial puncture sites but provided safe and effective closure of the subclavian artery puncture in our patient.
