Safety and arch complications after hemiarch versus total arch replacement with stented elephant trunk in acute type 1 dissection: Is a stent graft always beneficial?

ABSTRACT:

Objective

We aimed to determine the efficacy of total arch replacement with stented elephant trunk by comparing it with hemiarch replacement with and without open stent graft for acute aortic dissection type 1.

Methods

We reviewed records of 177 patients who underwent hemiarch replacement (HAR group) (concomitant open stent, 125) and 98 patients who underwent total arch replacement (TAR group) (concomitant stented elephant trunk, 91) for acute type 1 dissection. Compared with the TAR group, the HAR group was older (68.1 vs 60.9 years; P < .01) and had more thrombosed false lumen (28.8% vs 4.1%, P < .01).

Results

In-hospital death occurred for 7 patients in the HAR group and 1 patient in the TAR group (P = .17). More patients in the TAR group had a postoperative t
