A graft inversion technique for retrograde type A aortic dissection after thoracic endovascular repair for type B aortic dissection

Table 4 Comparative perioperative parameters

Variables	Graft inversion (n = 11)	Stepwise (n = 9)	P
Cardiopulmonary bypass time	165.8 ± 37.9 min	206.1 ± 46.8 min	0.047
Aortic cross-clamp time	124.5 ± 32.1 min	142.8 ± 36.5 min	0.25
Circulatory arrest time	34.5 ± 5.6 min	42.4 ± 9.5 min	0.031

Data are presented as n (%) or means (ranges). All perioperative variables were analyzed by t-test. P ≤ 0.05 was regarded as statistic significance
