Modified Cabrol's technique for composite replacement of the aortic valve and ascending aorta
1Department of Surgery, University of Iowa Hospital and Clinics, Iowa City 52242-1062.
Insights
A modified Cabrol technique for aortic root replacement simplifies coronary artery reattachment, improving hemostasis and surgical ease. This method offers a valuable option for complex cases and reoperations, with promising initial results.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Surgical Innovation
Background:
- Ascending aorta and aortic valve replacement with coronary reimplantation presents challenges, particularly intraoperative hemorrhage from coronary ostial anastomoses.
- Difficult exposure and repair of suture lines post-cardiopulmonary bypass in the intact aortic root complicate these procedures.
Purpose of the Study:
- To describe a modified Cabrol technique for aortic root replacement.
- To evaluate the efficacy and safety of this modified technique in managing bleeding complications.
Main Methods:
- Mobilization of coronary ostial buttons and resection of the entire aortic wall.
- Anastomosis of coronary ostia to the aortic conduit, with the entire repair wrapped in the aneurysm wall for hemostasis.
Main Results:
- The modified technique was used in five patients with diverse pathologies.
- No perioperative deaths were observed.
- One minor intraoperative neurological event occurred.
Conclusions:
- The modified Cabrol technique offers improved hemostasis and greater ease of operation.
- This approach is recommended for patients undergoing aortic root replacement, especially in complex cases and reoperations.
Abstract:
Composite replacement of the ascending aorta and aortic valve with coronary reimplantation can be complicated by intraoperative hemorrhage from the coronary ostial anastomoses and proximal aortic suture line. Exposure and repair of these suture lines may be quite difficult after the termination of bypass in the intact aortic root. Cabrol originally described connecting the coronary ostia by separate Dacron graft, which was then anastomosed side-to-side to the aortic conduit, and the entire repair wrapped in the aneurysm wall to control bleeding. This article describes a modification of Cabrol's technique in which coronary ostial buttons are mobilized and the entire aortic wall resected. This procedure has been used in five patients with varied pathology, with no perioperative deaths and one minor intraoperative neurological event. The greater ease of operation and improved hemostasis afforded by the technique described in this article warrant its consideration in patients requiring aortic root replacement, and may prove particularly helpful in complex cases and reoperations.
