[Scimitar syndrome with horseshoe lung (author's transl)].

A combination of two rare malformations of the lung was observed in a four-year-old asymptomatic boy. He had typical scimitar syndrome (dextrocardia, hypoplastic right lung and right-sided anomalous pulmonary venous drainage into the v. cava inferior) together with horseshoe lung.

[Isolated endocarditis of the tricuspid valve in early infancy].

A newborn baby is admitted in the second week of life with osteomyelitis and septicemia due to Staph. aureus infection. In his tenth week of life--the osteomyelitis nearly overcome--the infant shows signs of heart failure with a murmur and cyanosis.

[Visceral arteriography of hepatic, pancreatic and intraperitoneal tumours during childhood (author's transl)].

The value of visceral arteriography is discussed in relation to four hepatoblastomas, two vascular hamartomas of the liver, one inactive islet cell tumour of the pancreas and two malignant intraperitoneal tumours. Although non-invasive methods, such as computer tomography, sonography and scintigraphy are valuable, angiography is an important part of the pre-operative diagnosis of visceral tumours during childhood.

[Percutaneous nephropyelostomy: indications and technique (author's transl)].

Percutaneous nephropyelostomy has been performed on 24 patients. The method is simple, has few complications and can be performed rapidly; it can be recommended for both temporary and permanent supravesical urinary drainage. It represents an improvement in urologic techniques.

[Varicosities of the renal veins, the renal pelvis and the ureteric veins (author's transl)].

Varicosities of the renal veins and of the veins of the upper urinary tract may occur with or without haematuria. The urogram may be negative. Frequently, however, there are single or multiple impressions on the ureters as a result of the venous varicosities.

[Catheter embolization of malignant kidney tumors].

It is reported on the occlusion of the renal artery with Spongostan in 25 cases of malignant renal tumours. The embolisation takes place immediately after the angiographic diagnosis of the renal tumour, in which case on account of the simplicity of the method every radiologist working in the field of angiography is able to perform the occlusion of the renal artery. It is not difficult to get embolisation material and it is available in nearly every surgical department.

[Pulmonary sequestration (author's transl)].

Pulmonary sequestration is a relatively rare condition in which a part of lung tissue has no or only a secondary connection with the tracheobronchial tree. Blood supply comes from the aorta in anomalous branches. Sequestrations may be intra- or extralobar.

[Transposition of the great arteries with horizontal interventricular septum (author's transl)].

Transposition of the great arteries with horizontal interventricular septum is characterized by a superior-inferior relationship of the ventricular chambers in the presence of ventriculo-arterial discordance. Embryologically this very peculiar anatomy can be explained by a rotation of the bulboventricular loop around a sagittal axis. A typical case is reported.

[Arteriovenous aneurysm of the left internal thoracic artery with hypertrophy of the left upper limb (author's transl)].

Case report on a 5 years old boy suffering from a congenital arteriovenous fistula of the left internal thoracic artery. At the age of 9 months hypertrophy of the left arm combined with dilated veins in this area developed. Diagnosis was made by clinical examination together with a density in the left upper chest on x-ray and was confirmed by phlebography and thoracic aortography.

[Cerebral AV fistula with cardiac insufficiency in newborns (author's transl)].

A case of arteriovenous aneurysm of the great vein of Galen with congestive heart failure in a newborn infant is presented. Efficiancy of medical management and stop of growth of the head circumference point towards a good prognosis. Patients with this malformation have been divided into four clinical groups presenting with different symptoms in different ages.

[The syndrome of polysplenia (author's transl)].

A strong tendency to symmetrical development of the organ systems manifests itself in the syndrome of Polysplenia. These symmetrical organs show the anatomy of leftsided structures. For this reason the syndrome is also referred to as the "syndrome of bilateral leftsidedness".

[Williams-beuren-syndrome (author's transl)].

In the initial descriptions of the elfin-facies-syndrome by Williams and Beuren, supravalvular aortic stenosis was considered to be a constant feature of the syndrome, combined with retardation of mental and physical development, dentition anomalies and the peculiar face. According to newer findings, the missing of this deformity is no proof against the existence of the above-mentioned syndrome. Usually an elevation of the calcium-level is not found in the serum of these children, although there seems to be some relation to the calcium-metabolism.

Regional myocardial blood flow measurements before and after coronary bypass surgery. A preliminary report.

Myocardial blood flow in 16 patients before and after coronary bypass surgery in conjunction with coronary angiography, left ventricular function measurement, and graded exercise test. Radioactive 133-Xe was injected into the coronary artery or bypass graft and the washout was recorded by an Anger camera. Myocardial blood flow increased in 11 out of 14 patients and decreased in three patients.
