Abstract
|
|
|
In order to study the clinical and anatomic characteristics of the ventricular septal defects 282 patients with VSD underwent corrective open heart surgery during the period of 10 years and 4 months from january 1980 to april 1990 were reviewed.
The age
of patients ranged from 8 months 8 months to 36 years, and the mean age was 10 years. Upon Kirklin's anatomical classificantion, type I constituted 31.2%, type II 8%, type III 5.0%, and combined type I with II 1.4%, combined type II 8%, type III
5f.0%,
and combined type I with II 1.4%, combined type II with III 40%. 126 patients had associated cardiac anomalies, they were as follow, pulmonary stenosis 6, aortic insufficiency 10, subaortic stenosis 1, double chambered right ventricle 10 and
atrial
septal defect 20. Most of the patients had Qp/Qs of 1.5-1.8, Pp/Ps of 0.25 or less. The values of Qp/Qs, Pp/Ps and Rp/Rs were increased with close relation to the size of the defect. Fifty one patients (18.1%) developed postoperative
complications,
such
as thirteen patients of residual shunt, two patients of reexploration due to massive bleeding, seven patients of low cardiac output, two patients of detachment of patch. Operatie mortality rate was 2.4% (7cases) smong two hundered and eighty two
patients. The causes of inhospoital death were 5 low cardiac output, 1 cerebral hemorrhage and 1 ventricular fibrillation.
