Little is known about the real incidence and the clinical relevance of the enigmatic Monckeberg's medial calcification in the patency of the femoral artery allograft.

Abstract

Little is known about the real incidence and the clinical relevance of the enigmatic Monckeberg's medial calcification in the patency of the femoral artery allograft. Here we present a retrospective study on 143 multiorgan donors (mean age 38 years, range 14-59 years), to describe the incidence and the morphological features of vascular calcifications in banked femoral arteries suitable for clinical use. In the present series, focal vascular calcifications were present in 36 (25 %) cases, 23 cases localized in the intima, 7 in the media, and 6 were mixed. No correlation was found between the incidence of calcifications and the classical cardiovascular clinical risk factors (n = 9); only hypertension correlated with the medial localization, but not with the incidence, of the calcification (P = 0.017). While the macroscopic exclusion criteria of vascular grafts include atheromatous and not-atheromatous lesions, we ignore the actual impact of Monckeberg's medial calcification on vessel transplantation and allograft life. In our opinion this is a very important topic, since when the histological criteria for Monckeberg's calcification diagnosis are used, 25 % of our young donors population was affected. Whether Monckeberg's medial calcification is a stable arterial condition, apparently underestimated in the general population, or a dynamic process evolving with age and atherosclerosis, or a banking-related vascular alteration, still remain an open issue deserving further studies with subjects of different ages.
