Why the study?
Large bore access required for complex procedures increases the risk of vascular complications such as thrombosis and limb ischemia, necessitating management strategies for occlusive sheaths.
Provides practical strategies for interventional cardiologists to manage occlusive sheaths and prevent limb ischemia during large bore access procedures.
May prevent limb ischemia in large-bore access; leaves open need for prospective validation.
The field of interventional cardiology has evolved in its ability to carry out complex procedures. Procedures such as transcatheter aortic valve replacement (TAVR), endovascular aneurysm repair (EVAR), and mechanical circulatory support (MCS) devices require large bore access for successful deployment. With the use of large bore-access, comes with it an increased risk for vascular complications, such as thrombosis and limb ischemia. It is paramount for the interventional cardiologist to know how to manage such complications. In this manuscript, we describe our strategies for the management of occlusive sheaths increasingly encountered with large bore accesses in the upper and lower extremities. Strategies such as peeling away of the introducer sheath and the creation of internal and external bypass circuits are described. By using the described techniques, one can provide prolonged hemodynamic support and maintain large bore sheath access, without jeopardizing perfusion to the extremity.
