Open heart surgery for thrombosis of a prosthetic mitral valve during pregnancy. Fetal hydrocephalus.

Pregnant women with cardiac valvular prostheses present an important risk factor and the major complications are endocarditis and thromboembolism. Thromboembolism is determined by a hypercoagulation state. Compulsory anticoagulation treatment is an associated risk factor producing maternal and fetal complications. Different open heart surgical cases during pregnancy have been reported and a review of the literature shows favourable maternal prognosis. A 30-year-old woman with a Björk-Shiley mitral prosthesis, during the 6th week of pregnancy presented with thrombosis and embolism due to a change in anticoagulation treatment from acenocumarol to heparin. Open heart surgery was carried out and the patient's course was favourable. A fetal hydrocephaly of unknown etiology was discovered during the 18th week of pregnancy. Open heart surgery during pregnancy and the necessity of thromboembolic prophylaxis, have been analysed and revised.

Angiocardiographic demonstration of a partial defect of the pericardium with herniation of the left atrium and ventricle.

A case of a patient of 44 years of age with nonspecific thoracic symptomatology and anomalous protrusion of the second arch of the left border of the cardiac silhouette is reported. Cineangiocardiography showed a herniation of the left atrium and ventricle through a partial defect in the left pericardium demonstrating a mechanism that can give rise to sudden death by cardiac incarceration. Prophylactic longitudinal pericardiectomy was performed and the patient made an uneventful recovery.

[Cervical spondylosis and vertebrobasilar circulatory disorders].

The symptoms of cervical spondylosis may be removed or reduced in intensity by drug therapy or physiotherapeutic measures. Compression of the roots of the cerebrospinal nerves or the development of symptoms of myelopathy must be managed by surgery. The article discusses the pathophysiology of uncovertebral arthrosis or disorder of vertebrobasiliar circulation caused by spondylarthrosis of the falciform processes and the indications for operation. Analysis of the results of operation for decompression of the spinal arteries, performed on 4 patients, supplies grounds for the conclusion that the spinal artery is compressed not only by the spondylolytic masses but also by a cicatricial connective-tissue ring which forms about it and causes a direct stenosing effect. This factor acquires importance in the formation of morphological changes in the late stage of ttion of the cicatricial ring embracing the vessel. The results of the operative intervention are satisfactory.

[Transsphenoidal approach in pituitary adenomas with suprasellar growth].

Experience in surgery through a transsphenoidal approach in 154 patients with suprasellar adenomas of the hypophysis complicated by disorders of vision is discussed. Positive changes of vision after the operation occurred in most cases. At the Budapest Scientific Research Institute of Neurosurgery the transsphenoidal approach to adenomas of the hypophysis is used in most cases, and only 10% of patients are operated on transcranially when there are tumors with parasellar growth. The authors persist in their opinion that the transsphenoidal approach is simpler in techniques and causes less injury as a result of which it can be used even in elderly patients and in those whose general condition is grave.

[Radiological and angiocardiographical aspects of primary endocardial fibroelastosis in children (author's transl)].

In this article we try to show the value of radiography and angiocardiography in primary endocardial fibroelastosis. The 20 CASEs studied in this report, were angiocardiographically and/or necropsically proved. In spite of different opinions, we think that it is possible to reach an approximate diagnosis of this condition if we use the clinical and angiohemodinamic examinations. On the other hand, it is necessary to point out that pathology is characteristic. The most important radiological signs were cardiomegaly, together with venocapilar congestion, both of variable magnitude, and dependent on the degree of cardiac insufficiency. By means of angiocardiography we could appreciate a great dilatation and hypertrophy of the left ventricle and a reduction of the mobility and distensibility of this cavity along the cardiac cycle.

[Aortic coarctation. Treatment under one year (author's transl)].

Fifteen patients operated upon for aortic coarctation under one year are reported. Nine of them survived. The E.C.G. was very useful as far as the surgical prognosis is concerned. Dead patients showed either right or biventricular hypertrophy, with alteration of the repolarisation. On the other hand 50% of survivors had left ventricular hypertrophy. In six of the operated patients a plasty between subclavian artery and aortic arch was performed. The remaining patients were treated by end-to-end anastomosis.

[Pulmonary atresia with intact i.v. septum (author's transl)].

Eight cases of pulmonary atresia with intact ventricular septum, are reviewed. Three corresponded to the group with small or hypoplastic right ventricle and five to the one with normal or enlarged right ventricular cavity. The electrocardiogram was of less value than plain chest radiography for the differential diagnosis of both groups. Cardiac catheterization revealed a right to left atrial shunt and the suprasystemic level of the right ventricular pressure. Selective angiocardiography demonstrates the stop of contrast at the level of pulmonary valve. Five patients were operated. An ascending aorta to right pulmonary artery anastomosis, Waterston type, was performed in three patients. Pulmonary valvotomy was carried out in the others.
