Classic shunting operations as part of two-stage repair for tetralogy of Fallot.

One hundred forty-nine consecutive patients with tetralogy of Fallot, with or without pulmonary atresia, underwent Blalock-Taussig or Waterston operation for initial palliation. Of these patients, 45 were less than 6 months old, and 63 were less than 1 year old. The type of shunt, and the presence or absence of pulmonary atresia did not have a significant effect (p greater than 0.2) on hospital mortality. Parametric analysis showed a significant effect of age (p = 0.03), the risk of hospital death being 6% at 1 month of age, 4% at 3 months, 3% at 6 months, and 2.5% at 12 months. No late deaths occurred before the age of 3 years. Six patients (4.2% of the hospital survivors) required another operation before they were 3 years old. Severe arm ischemia occurred after a Blalock-Taussig shunt in 1 infant with Down's syndrome.

Surgical management of congenital vascular rings.

Case histories of 53 patients with surgically treated vascular rings are presented. The diagnosis was strongly suggested in all patients by symptoms of tracheosophageal obstruction and was confirmed by barium esophagogram, which showed typical bilateral and posterior indentations in the esophagus. Angiography was rarely used although it is helpful in doubtful cases. Endoscopic studies were considered unnecessary and potentially harmful. A left posterolateral thoractomy afforded ample access for division of the ring in all patients. Two patients died who were operated upon during the early experience. There were no postoperative deaths among the last 45 consecutive patients. All survivors had excellent symptomatic relief although complete resolution of symptoms took several months in some patients. All survivors had excellent symptomatic relief although complete resolution of symptoms took several months in some patients. The importance of early diagnosis and prompt surgical division is emphasized.

Echocardiographic features in a case of intrapericardial teratoma.

An infant presented with symptoms of congestive heart failure. Ultrasound examination revealed a dense layer of echoes at the root of the aorta, a large anterior pericardial effusion, and coarse fluttering of the right ventricular wall. The clinical diagnosis of intrapericardial teratoma was confirmed by cineangiography and surgical resection. The pathological examination was consistent with benign teratoma. A postoperative ultrasound examination revealed absence of pericardial effusion and tumor echoes. This appears to be the first echocardiographic report of a pericardial tumor in an infant.

Prevalence of epilepsy in Bogota, Colombia.

A combined epidemiologic, clinical, and electroencephalographic study of epilepsy was undertaken in Bogota by the Neurological Institute of Colombia, the Colombian Institute of Health, and the Department of Health of the City of Bogota. The prevalence of epilepsy on December 31, 1974, was 19.5 per 1,000, the highest rate for general populations reported in the literature. The prevalence was significantly higher for females than for males, 22.9 per 1,000 compared with 15.5 per 1,000.

Symptomatic anomalies of the aortic arch.

Twenty-eight patients with anomalies of the aortic arch producing compression of the trachea and the esophagus have undergone surgical correction at this hospital since 1949. Of the vascular rings encountered, 15 had a double aortic arch and eight, a right aortic arch with a constricting ligamentum arteriosum. Five had an aberrant right subclavian artery passing posterior to the esophagus producing dysphagia. The patients with the double aortic arch were all infants. Two of the patients with a right arch and constricting ligamentum arteriosum and one patient with a retroesophageal subclavian artery were adults. Stridor from pressure on the trachea was the common symptom in the infants. The diagnosis was confirmed by esophagograms; aortography was less helpful. The surgical approach was the same for all of the anomalies, through a posterolateral incision in the left fourth interspace. For the double arches, the smaller limb, usually the anterior, was divided. Division of the ligament relieved the constriction of the right aortic arches, and the anomalous right subclavian artery was divided near the aorta. There were no hospital deaths, but one infant with a double aortic arch operated upon at the age of two weeks and with a tracheostomy died at home seven months later.

Echocardiographic pattern of right atrial tumour motion.

Propagation of Wilm's tumour to the right atrium was diagnosed by echocardiography. The tumour prolapsed into the right ventricle during each atrial systole. The presence of the tumour and its motion were confirmed by cardiac catheterization, cineangiography, and surgical exploration. Successful resection of the tumour was accomplished. Echocardiography was helpful in detecting the presence of the right atrial tumour and accurately reflected the pattern of its atrioventricular motion.

Fatal air embolism during thoracotomy for gunshot injury to the lung. Report of a case.

Fatal coronary air embolism occurred during thoracotomy in a patient with a gunshot wound involving the hilum of the right lung. Embolism was observed during a second period of failure of heart action. Evidently, air entered the pulmonary veins from the bronchus, which was receiving positive-pressure ventilation. The literature contains reports of only 3 similar cases, but we suspect that air embolism may be responsible for death and morbidity in additional cases in which accidental or iatrogenic lung trauma has produced a pathway between the bronchial tree and the pulmonary veins.
