OBJECTIVES To determine the case incidence of ductus arterious aneurysm among our neonates, and to report on our experience in the presentation, echocardiographic features, management and outcome of this condition. METHODS Retrospective review of cases diagnosed within a 1-year period from 1 July 1998 to 30 June 1999. RESULTS Eight cases of neonatal ductus arteriosus aneurysm (DAA) were dia...
Histopathological studies were made on 9 necropsy specimens of ductus arteriosus with hypoplastic left heart syndrome and I with rubella syndrome. A control group of 40 normal specimens were also studied. In the 17th week of gestation, ductus arteriosus was composed of few elastic fibers, a thick continuous internal elastic lamina and a wide hypocellular area. In the 8th month of gestation, the...
Circulus arteriosus (Circle of Willis) is an anastomotic ring which unites the internal carotid and vertebrobasilar systems. It slows down the blood before it reaches the brain and helps in collateral circulation. Anatomic study reveals the variation in the pattern and calibre of vessels which make up the circulus arteriosus. The greatest variation in calibre occurs in the posterior communicati...
OBJECTIVE Systemic-to-pulmonary shunt operations are still required for palliation of certain congenital heart defects.

Surgical closure of patent ductus arteriosus in adults involves a number of risks because there are associated anatomic and histologic alterations. Between October 1992 and August 2008, 23 patients were referred to our department with isolated patent ductus arteriosus. Their age ranged from 16-75 years (median 25.5 years) and their weight from 52-80 kg (median 57 kg). The pulmonary diameter ran...
Background: VACTERL association is usually a sporadic disorder, the possible etiologies of which have been proposed as familial as well as multiple genetic and environmental factors. VACTERL association usually consists of at least three of the core features of vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, and limb abnormalities. Vertebral anomali...
In this retrospective study, 510 infants and children with patent ductus arteriosus (PDA) who underwent surgery at the Shahid Rajai Heart Hospital in Tehran were evaluated to determine the rate of surgical complications, morbidity and mortality. 30 patients (6%) developed minor to major complications postoperatively. Four patients who had undergone PDA ligation without division required reo...
