[Vertebral arteriovenous fistula and neonatal cardiac insufficiency: diagnosis using duplex Doppler echography]. / Fístula arteriovenosa vertebral e insuficiencia cardiaca neonatal: diagnóstico por ecografía Doppler dúplex.

An extracranial arteriovenous fistula case, placed in vertebral artery territory that dealt with congestive heart failure and which developed advantageously without a surgical treatment is shown. Authors emphasize the fact of being a rarity the so premature beginning of the signs in a arteriovenous communication at that level, results in Doppler duplex echography and the need to have in count this entity previous to congestive heart failure with a deep origin in neonatal period.

[Severe aortic stenosis in the neonate and infant under 6 months old]. / Estenosis aórtica severa en el recién nacido y lactante menor de seis meses.

24 patients with diagnosed aortic stenosis are reported. Clinical symptoms started before 6 months of age (between 24 hours and 6 months, average 87 days). In all cases aortic stenosis was the only existing malformation, except in one patient who had a small muscular ventricular septal defect and in another case who had a patent ductus arteriosus. Clinical symptoms were early and notable. In nineteen there was congestive heart failure whose appearance in the first week of like was a bad prognosis. Relationship between severity of aortic stenosis and electrocardiographic findings was closer than in older patients. Death rate was very high in children who had not been operated (5 out of 12). Of children who received surgery only one died out of 12. Treatment, therefore, in this pathology must be aggressive.

[Aortic coarctation in children. Analysis of 100 cases]. / Coartación de aorta en el niño. Análisis de 100 casos.

One hundred clinical records of coarctation of aorta are presented with 78% catheterization and 31% postmortem examination. Surgical treatment was performed in 46%, 8, in the first month of life, 13 from 1 to 6 month, 5, from 6 to 12 month, 9 from 12 to 24 month and 11 older than 2 years. The surgical mortality was 13%. There was recoarctation in 7.5%. The mortality in the patients not operated on was 31%. This mortality was influenced by the severity of associated malformations. The most frequent associated cardiac malformations were left to right shunts followed by left heart pathology. The association with complex cardiopathies was frequent.
