Factors Associated With Operative Mortality Among Patients Admitted With Thoracic Aortic Aneurysm/dissection in Kenyatta National Hospital: a Retrospective Cohort Study
Abstract
Introduction: Thoracic aorta aneurysms (TAA) and Thoracic aorta dissection (TAD) are
linked to significant morbidity and mortality. The incidence of death, undesirable postoperative
complications and risk factors for mortality after undergoing open surgical repair
for TAA/TAD remain largely unknown in Kenyatta National Hospital among patients
undergoing management for TAA and TAD. Understanding the risk factors associated with
operative mortality among patients with TAA and TAD would help improve patient
selection for surgery hence reduce mortality and complications associated with the surgery.
Objectives: The objective of this study was to determine the rate of operative mortality
and the risk factors associated with operative mortality among patients who underwent
thoracic artery aneurysm/dissection surgical repair.
Methodology: This was a retrospective cross section study with a sample size of 31 cases.
Data was collected from patient files retrieved from the records department at Kenyatta
National Hospital. The study population included patients managed for thoracic aortic
aneurysm/dissection at Kenyatta National Hospital from July 2010 to June 2020 through
open surgical repair technique. Exposure variables were collected on socio-demographic,
clinical factors, anatomical, radiological findings, intraoperative outcomes, the nature of
the procedure done, time under Cardio-pulmonary bypass (CPB) and postoperative
complications with the outcome variable as the 30-day mortality.
Data analysis: Stata 13.0 was used for data analysis. Means and medians were used to
describe characteristics of the study participants. For univariate risk factor analysis Chi................................................................
