[Left Subclavian Artery Occlusion by Using Amplatzer Vascular Plug I During Thoracic Endovascular Repair].

OBJECTIVE

The purpose of this study is to report the use of Amplatzer Vascular Plug (AVP) I for left subclavian artery (LSCA) occlusion during thoracic endovascular repair (TEVAR) with extra-anatomical bypass.

METHODS

Retrospective review was undertaken in twelve patients who underwent transcatheter occlusion of the LSCA with AVP I as a part of TEVAR of thoracic aneurysm and aortic dissection at a single institution between Feb. 2014 and Jul. 2015.

RESULT: Mean age was 72.4±9.4 years old. Seven patients were diagnosed with aortic aneurysm and 5 with aortic dissection. Mean operative time was 207.8±43.1 minutes. An extra-anatomical bypass to LSCA was performed in all cases, of which 2 cases underwent an additional extra-anatomical bypass to left carotid artery. We used 12 mm size of AVP in 1 case, 14 mm in 7 cases, and 16 mm in 4 cases. Mean follow-up time was 6.3±4.6 months. There was no death and device-related or aorta-related complications after discharge.

CONCLUSION

We reported the use of AVP I for LSCA embolization during TEVAR with extra-anatomical bypass. This result suggested that this method was effective and could be used from here on.
