Why the study?
Given the relative paucity of experience with percutaneous axillary artery access, little is known about the consequences of in-dwelling Impella devices percutaneously placed in the axillary artery.
This study explores the safety and vascular complications, specifically thrombus formation, associated with percutaneous axillary artery microaxial pump insertion.
Axillary Impella access may aid mobility in high-risk PCI; leaves open safety and durability questions pending larger studies.
percutaneous coronary intervention prevalence T he Impella family of microaxial pumps (Abiomed, Danvers, MA) have been increasingly used in high risk percutaneous coronary intervention and in patients with hemodynamically unstable cardiovascular disease. 1 Use of the axillary artery (AA) for percutaneous Impella implantation, as has been recently described, 2 is alluring based on patient mobility and less atherosclerotic disease burden. 3 Given the relative paucity of experience with percutaneous AA access, little is known about the consequences of in-dwelling Impella devices percutaneously placed in the AA. In this single-center experience, we performed a systematic angiographic analysis of percutaneous AA Impella implants to explore the possibility and prevalence of AA thrombus formation, patterns of collateral blood flow, and potential for ischemic upper extremity injury.
