Summary

Management strategy of malperfusion syndrome in acute type A aortic dissection (ATAAD) patients remains controversial, with different views on when the surgery should be offered. At present, the mortality of ATAAD patients complicated with malperfusion is stubbornly high.

The purpose of this study is to improve the outcomes of ATAAD with malperfusion syndrome. The investigators formulated tailored management strategies for malperfused patients based on the duration of symptoms onset.

Conditions

  • Aortic Dissection

Interventions

PROCEDURE

Tailored management strategies

Our basic surgical strategies for the central repair operations for ATAAD are as follows. As arterial lines for cardiopulmonary bypass, side branches of the axillary and femoral arteries were used. Circulatory arrest was established when the nasopharyngeal temperature reached 25°C. Anterograde selective cerebral perfusion was performed through the right axillary artery, and the brain was perfused at approximately 5 mL/kg/min. The extent of aortic replacement was determined according to the extent of dissection involvement. For malperfused patients with symptom onset within 6 hours, the immediate central repair was performed followed by repeat CTA postoperatively, and endovascular reperfusion was applied if the malperfusion persisted. While for patients with symptom onset beyond 6 hours, delayed central repair were performed after the organ functions improved.
