[Diagnosis and surgical treatment of carotid body chemodectoma].

The authors present an analysis of clinical, angiographic and operation finginds in 11 patients showing large chemodectomas with involvement of the common, external and internal carotid arteries and jugular vein. The carotid body angiography was found to be of great diagnostic value. In the presence of a patent internal carotid in 10 cases radical chemodectomy was performed, preserving the patent internal carotid and the vein. In case of a pathologically convoluted internal carotid the common carotid artery was resected with an end-to-end anastomosis. Late results were favourable even in patients with histological signs of an incipient malignant transformation of chemodectomy.

[Indications for surgical treatment of cerebrovascular insufficiency in patients with occlusive lesions in the brachiocephalic vessels].

The authors studied and operated on 172 patients with cerebro-vascular insufficiency due to occlusional lesions of the brachiocephalic vessels. According to the pre-operational signs of cerebro-vascular insufficiency 4 clinical groups were distinguished; 1) with asymptomatical oclusions; 2) transient disorders of cerebral circulation; 3) with chronic cerebro-vascular insufficiency and 4) with ischemic strokes. On the basis of an analysis of the direct and remote results of reconstructional operations indications to surgical treatment were determined. The best results were obtained in patients of the 1st and the 2nd groups, where the blood flow in the reconstructed vessel was restituted in 74 and 92% of the cases. Poor result of surgical treatment was seen in patients with severe brain lesions, especially after repeated ischemic strokes. However, in patients of the 3d and 4th groups with moderately crude cerebral changes it was possible to restitute the blood flow in 57% of the cases most frequently on the side contralateral to the lesion. The conclusion is made that surgical treatment is definitely indicated in asymptomatic occlusions and transient disorders of cerebral circulation as well as in chronic cerebro-vascular insufficiency and ischemic strokes, if however, the neurological deficiency is moderate.

[Blood supply and the atrioventricular conduction system of the dog heart].

In 30 experiments in order to specify the blood supply and conducting system in the dog heart, coronal arteries were injected with a contrasting mass that was followed by roentgenography and preparation of the coronal arteries. The topography and blood supply of the atrioventricular conducting system with application of prevital blood supply, and the left coronal artery is the main source of blood supply for all the parts of the cardiac atrioventricular conducting system.

[Renal angiography with the use of vasoactive drugs and its value in the diagnosis of vasorenal hypertension].

The results of 76 selective renal angiographies in 33 patients with the use of adrenalin and acetylcholine are presented (17 cases of renovascular hypertension, 7-chronic pyelonephritis, 5-essential hypertension, 2-nephroptosis, 1-kidney tumor). The pecularities of the method essential for the success of the examination and prevention of complications are described. The importance of pharmacoangiography with adrenalin for the determination of the length of renal vessels lesion in cases of fibrous dysplasia was demonstrated, as well as that of the acetylcholine test for examining the state of the vascular bed of the contralateral kidney, the same procedures being applied in cases of chronic pyelonephritis. Typical pharmacoangiographic symptoms of different forms of nephrogenic hypertension are described.

[Diagnosis and clinical course of occlusive lesions of the main trunk of the left coronary artery].

A total of 50 patients with the left coronary artery trunk stenosed by more than 50 per cent were examined. General clinical methods, ECG under physical efforts and selective coronarography were employed. According to the authors this amounts to 6.4% of all corronarographically investigated patients. A comparison of the results derived from these investigations furnished fairly reliable clinical signs suggesting the existence of the stenosed trunk prior to coronarography. The authors feel that a preliminary diagnosis of such a lesion dictates an urgent coronarography. A careful and reserved approach to the investigation and a number of modifications in the procedure used by the authors are factors substantially diminishing the risk of this investigation.

[Compensation of disorders of coronary circulation by means of collaterals (according to coronarographic data].

On the basis of an analysis of about 1000 coronary angiogrammes it is established that collaterals develop in stenosis of the coronary arteries in 52.3% of the patients surviving myocardial infarction, and in 20% of those free of myocardial infarction. Coronary angiogrammes of 100 patients with coronary collaterals were examined. Twenty different ways of collateral circulation were revealed. Certain regularities were noted in the development of collaterals depending on the lesions of different coronaries or combined lesions of several arteries. Intersystemic collaterals are most typical for the occlusions of the anterior interventricular branch. In cases of occlusions of the right coronary artery either intersystemic, or intrasystemic collaterals develop, depending on the localization of the occlusion. A study of the collaterals in cases of multiple coronary lesions has demonstrated that under such conditions a complicated system of anastomoses develops, and the flow in them is multidirectional.

[Surgical treatment of congenital spindle-shaped aneurysms of the internal jugular vein].

In 6 of 12 investigated patients resection of a congenital aneurysms of the internal jugular vein was accomplished. In 2 of them venous patency was restored by means of a longitudinal-lateral suture after resection of a sac-shaped aneurysm, while in 4--following circular resection of a spindle-shaped aneurysm the vein was reconstructed by an end- to-end anastomosis. Phlebographic studies in 2 patients 10 and 12 months after reconstruction of the internal jugular vein have demonstrated great perspectives of employing such operation in clinical practice.

[Clinical characteristics of angina pectoris in relation to disease of the coronary arteries].

Clinical and coronary angiographic comparison conducted in 164 patients with typical angina pectoris demonstrated that the nature of the pains may serve as a criterion of the degree of stenosis and the number of diseased arteries. The development of typical anginal seizures indicates the presence of clear changes in the coronary arteries. A daily intake of over 10 pills of nitroglycerine is a sign of a narrowing of the diameter of the coronary arteries exceeding 75%. A growing number of daily taken pills of nitroglycerine indicates an increase in number of diseased coronaries. Pains occurring during or after meals, when lying down, awakening the patient at night are typical for coronary narrowings exceeding 75% of their diameter. Usually such pains are observed in patients with 2 and more cornary arteries affected by the disease. Rightward irradiation and especially strictly localized pains are often associated with the lesion of the right coronary artery.
