Abstract
Inadvertent line insertion into the subclavian artery is an uncommon complication of subclavian venous catheterisation, and its timely recognition is vital to minimise risk of harm to the patient. We describe the radiographic, computed tomographic (CT), and angiographic findings in two patients and illustrate the subsequent endovascular management using collagen vascular closure devices.
Highlights
Subclavian vein catheterisation is a commonly performed procedure [1], with inadvertent puncture of the subclavian artery representing an uncommon but potentially fatal complication [1, 2].We report two cases in which the subclavian artery was accidentally catheterised during attempted subclavian venous cannulation
The catheter was removed in the interventional suite and the arterial puncture closed with an Angio-Seal vascular closure device
This complication is often recognised early. In cases such as ours, with hypotensive and unstable patients, Figure 5: Chest radiograph showing abnormal position of the left subclavian line. This can be more difficult to detect owing to the lack of pulsatile flow secondary to hypovolaemia
Summary
Subclavian vein catheterisation is a commonly performed procedure [1], with inadvertent puncture of the subclavian artery representing an uncommon but potentially fatal complication [1, 2]. We report two cases in which the subclavian artery was accidentally catheterised during attempted subclavian venous cannulation. In both cases, the catheter was removed in the interventional suite and the arterial puncture closed with an Angio-Seal vascular closure device (St. Jude Medical; St. Paul, MN). The radiographic, computed tomographic (CT), and angiographic findings are presented here. We review the literature for management of iatrogenic subclavian arterial cannulation
