Limited data are available on the use of xenopericardium in the treatment of native and graft-related aortic infections. The aim of this review was to assess outcomes of neoaortic reconstruction using xenopericardium in this challenging group of patients.


Studies involving xenopericardial graft reconstruction to treat native and aortic graft infections were systematically searched and reviewed (Embase, Medline, and Cochrane databases) for the period of January 2007 to December 2017.


A total of 4 studies describing 71 patients treated for aortic graft (n = 54) and native aortic (n = 17) infections were included; 25 patients (35%) were operated on in an acute setting. The technical success rate was 100%. The mean 30-day mortality was 25% (range, 7.7%-31%). Only one death (1.4%) was linked to the operator-made pericardial tube graft (acute postoperative bleeding from proximal anastomosis). Septic multiorgan failure was the most common cause of perioperative death (72% [13/18]). Among the 53 patients who survived, only 3 presented with recurrent infection (5.7%), so 70.4% of patients were alive after intervention without evidence of infection (50/71). During follow-up, 2 false aneurysms (3.7% [2/53]), 1 early rupture (1.4% [1/71]), and 2 cases (3.7% [2/53]) of late rupture were reported. Other causes of late deaths unrelated to the aortic xenopericardial repair were not reported in the different series. The early reintervention rate was 1.4% (1/71), treated by open repair for rupture. The late reintervention rate was 7.5% (4/53) with thoracic endovascular aortic repair in three patients (one false aneurysm and two ruptures) and open repair in one patient (one false aneurysm). There were no cases of early or late graft thrombosis. One-year mortality rate was 38% but only 4.2% were related to the aortic repair using orthotopic xenopericardium (one early and two late ruptures).


These data confirm the high morbidity of native and graft-related aortic infections and provide insight into the results of orthotopic xenografts as a treatment alternative. Larger series and longer follow-up will be required to compare the role of operator-made pericardial tube graft with other treatment options in infected fields.
