Acute type A aortic dissection and pregnancy: a population-based study

Abstract

Acute aortic dissection represents a rare pathology in women younger than 45 years of age; however, it is associated with a high rate of sudden death. Pregnancy may not be a risk factor for this life-threatening vascular emergency. Immediate referral to surgery, even during pregnancy, will result in a prognosis of favorable outcome.

Hybrid surgical reconstruction of aorta dissection manifested during pregnancy

“…При этом, распростра-ненность диссекции аорты типа А у беременных и рожениц составляет всего 0,01% от общего числа диссекций аорты [6]. Согласно обзору Yuan SM, et al…”

“…По данным литературы, расслоение аорты может развиться в любой период беременности [1,2,6], однако наиболее часто встречается в третьем триме-стре (51% случаев) и послеродовой период (20% слу-чаев) [7]. В первом и втором триместрах беремен-ности риск расслоения аорты минимален и состав-ляет 6% и 10%, соответственно [8].…”

Maternal Death Due to Acute Aortic Dissection-Autopsy Diagnosis: A Case Report

“…The incidence of acute aortic dissection during pregnancy is 0.4 cases per 100,000 person years [5,6]. The estimated incidence of aortic dissection was 11.7-fold higher in pregnant women compared to non-pregnant women [9].…”

“…But female population generally present with the disease at later ages compared to males [4]. The incidence of acute aortic dissection during pregnancy is about 0.4 cases per 100,000 person years [5,6]. Half of the aortic dissection cases occur in the third trimester of pregnancy and in the postpartum period when the hemodynamic stress is the greatest [1,7].…”

Cardiovascular Catastrophes in the Obstetric Population

“…4 From a cardiovascular standpoint, during pregnancy, afterload is increased because of increased systemic vascular resistance (SVR), preload is decreased because of diminished volume expansion, and intravascular fluid shifts into third spaces (especially the lungs) because of endothelial injury related to hypertension. 5 Prolonged, uncontrolled hypertension puts the patient at increased risk of aortic or coronary artery dissection 6,7 and PPCM 8 (both are discussed later in this article). Blunted volume expansion, 9 in addition to renal artery vasospasm, 10 significantly decreases renal flow and glomerular filtration rate, causing impressive oliguria.…”
