Abstract

Purpose: To retrospectively review a 9-year experience with endovascular management of inadvertent subclavian artery catheterization during subclavian vein cannulation.

Materials and methods: From June 2000 through July 2009 (109 months), 13 patients underwent endovascular management of inadvertent subclavian artery catheterization. All catheters were still in situ, including one 7-F catheter, six 8-F catheters, and six large-bore 10-11-F catheters. Treatment was performed with an Angio-Seal device (n = 6) or balloon catheters (n = 7) and by additional stent-graft placement (n = 4).

Results: Mean follow-up was 27.3 months (range, 0.4-78 months). The 30-day mortality rate was 7.7% and the late mortality rate was 46.1%. Primary technical success was achieved in nine patients (69.2%), in four with the use of a compliant balloon catheter and in the other five with an Angio-Seal device. Complications required additional stent-graft placement in four patients (30.8%), one because of stenosis after Angio-Seal device deployment and three as a result of insufficient closure of the puncture site by balloon tamponade. Stent-graft repair was successful in all four patients, for a primary assisted technical success rate of 100%.

Conclusions: Endovascular techniques offer a less invasive alternative to surgery. The present limited experience shows that the use of the Angio-Seal device is not without risks, whereas balloon tamponade is not always reliable in closing the puncture site. Stent-graft placement may be required in patients in whom balloon tamponade fails or in whom the use of the Angio-Seal device is contraindicated.
