Safety of Left Subclavian Artery Selective Coverage without Revascularization in Thoracic Endovascular Aortic Repair for Type B Aortic Dissections.

ABSTRACT:

Purpose

Whether to proceed left subclavian artery (LSA) revascularization in patients with LSA coverage due to insufficient proximal landing zone (PLZ) during thoracic endovascular aortic repair (TEVAR) remains controversial.

Methods

A total of 903 patients who received TEVAR were retrospectively analyzed. LSA could be covered if the PLZ was less than 15 mm accompanied with 1) a dominant or balanced right vertebral artery, 2) a complete circle of Willis, and 3) a left vertebral artery with a diameter ≥3 mm and without severe stenosis.

Results

LSA selective coverage was necessary for 35.0% (316/903) of the patients to extend the PLZ. Patients presented with weakness, pain, cooling and discoloration of the left upper extremity (LUE), and pulselessness of the left brachi
