Summary

The ACE trial is a multicentre, randomized controlled trial comparing axillary vs. innominate artery cannulation for established antegrade cerebral perfusion in patients having aortic surgery (thoracic and aortic arch) requiring deep hypothermic circulatory arrest using a non-inferiority trial design.

Conditions

  • Aortic Aneurysm, Thoracic

Interventions

PROCEDURE

Axillary artery cannulation

The right axillary artery will be exposed via an infraclavicular incision and a Dacron graft sewn to it in an end to side fashion after 5000 units of IV heparin. Following median sternotomy and full systemic heparinization, CPB will be initiated and the patient cooled. The base of the innominate artery will be clamped, and antegrade cerebral perfusion will be provided via the axillary artery. Following completion of the distal open aortic anastomosis, the clamp on the innominate artery will be removed, CPB via the aorta will be resumed and the patient will be rewarmed. After completion of surgery and weaning from CPB, the axillary artery graft will then be removed, the artery repaired and the skin will be closed.

PROCEDURE

Innominate artery cannulation

After median sternotomy, systemic heparinization, cannulation of the ascending aorta and right atrium, CPB and systemic cooling will be initiated. The ascending aorta, proximal arch and the base of the innominate artery will be mobilized. Purse-string sutures are placed on the anterior wall of the proximal innominate artery and a pediatric venous cannula inserted using a J wire and sequential dilatation. Circulatory arrest with ACP is provided by clamping the base of the innominate artery and connecting the afferent limb of the CPB circuit to the innominate cannula. Once the distal aortic anastomosis is completed, ACP is discontinued, and full CPB via the aortic graft is resumed. Rewarming and the remaining surgery are then completed.
