Partial Right Atrial Inflow Occlusion for Transient Systemic Hypotension During Deployment of Thoracic Stentgrafts

Year: 2021

Type: article

Abstract: PURPOSE: Temporary balloon occlusion of the inferior vena cava to lower cardiac output is a relatively infrequently used technique to induce controlled systemic hypotension. In this technical note, we describe the feasibility, reliability, and safety of partial occlusion of right atrial inflow and the effect on systemic blood pressure during the deployment of a thoracic stentgraft. MATERIALS AND METHODS: Twenty consecutive patients undergoing thoracic endovascular aortic repair, with proximal landing in zone 0-3 of the thoracic aorta, were prospectively included. Right atrial inflow occlusion was performed with a compliant occlusion balloon. RESULTS: Median time to reach a mean arterial pressure of 50 mmHg was 43 s. Median recovery time of blood pressure was 42 s. CONCLUSION: Partial right atrial inflow occlusion with an occlusion balloon is feasible with reliable results and without procedure-related complications.
