OBJECTIVE
To evaluate the short-term results of simultaneous combined interventions on supra-aortic arteries, ascending aorta and aortic arch.
MATERIAL AND METHODS
There were 330 patients who underwent surgery for acute or chronic type A aortic dissection between 2011 and 2020. Significant damage to brachiocephalic arteries was identified in 33 (10%) patients. Men prevailed (n=21). Mean age of patients was 49±12.7 years (range 18 — 66). Damage to brachiocephalic arteries and aorta was determined by acute (n=3), subacute (n=9) and chronic (n=21) dissection. Adaptive perfusion, adaptive loop of arterial circuit and two perfusion pumps were used to ensure cerebral and visceral protection. Brain protection strategy and cerebral perfusion quality were analyzed using oximetry and transcranial Doppler sonography. Early outcomes of simultaneous combined operations were retrospectively assessed.
RESULTS
Total aortic arch replacement was performed in 15 patients, subtotal replacement — in 16 patients. No arch replacement was required in 2 cases. Conventional arch replacement using branched prosthesis was carried out in 10 patients, branch-first technique — in 23 cases. Supracoronary ascending aortic replacement was performed in 24 patients, Bentall-DeBono procedure — in 7 cases. Correction of ≥2 supra-aortic vessels was performed in 16 (48.5%) patients. In-hospital mortality was 12.1% (n=4). The main causes of mortality were bleeding following coagulopathy (n=2), cerebral edema (n=1), embolic occlusion of coronary artery (n=1). Postoperative stroke occurred in 3 (9.1%) patients, transient neurological deficit — in 5 (15.2%) cases.
CONCLUSION
Combined repair of proximal aortic segments and supra-aortic vessels is possible in case of high risk of cerebral malperfusion in patients with aortic dissection.
