Limb circulation in varicosity of various types.

Regulation of limb circulation was studied by the use of the venous isotope dilution technique in 35 patients with leg varicosities. The circulatory parameters of 54 patients with normal limb circulation served as control. The various types of varicosity revealed characteristic circulatory patterns. (i) In the cases of congenital, "juvenile", varicosity limb blood flow is high, the limb AV-O2 difference is very slight and limb O2 uptake is normal. (ii) In secondary varicosity consecutive to thrombophlebitis the limb (total) blood flow is slightly reduced, the limb AV-O2 difference is smaller than normal and O2 uptake by the extremital tissues is diminished. (iii) In non-congenital, primary varicosity, i.e. in the most common form, limb blood flow is normal, the limb vascular resistance is slightly increased. The possibilities of the production of an AV shunt and the clinical implications of the circulatory changes accompanying the various types of varicosity are discussed.

[Factors determining the patency of experimental anastomoses between lymphatic vessels and veins].

End-to-end anastomoses between lymph vessels and veins performed under microscopy (magnification lox--20 x) may be useful in the treatment of certain types of lymphoedema. End-to-end anastomosis of the vena profunda femoris and a deeply localized lymph vessel have been performed on the hind-legs of 10 dogs. Scanning electron microscopic investigation of the anastomosis has been carried out at 0h, 48h and 8 days respectively after the operation. Scanning electron micrographs of the inner surface of the anastomosis indicate that blood flow though the anastomosis can be achieved by atraumatic surgical technique (by the use of thin) 10/0) sewing material and needle. Injury to the endothelial surface results in platelet and erythrocyte aggregation. 8 days after the operation the inner surface of the anastomosis is covered by cells (endothelium?). Early development of a new inner cell layer can prevent occlusion of the shunt.

Application of Solcograft in vascular surgery.

Incorporation of Solcograft was studied experimentally and clinically. The graft was found to facilitate the formation of continuous endothelium which starts at the vessel graft boundary and from newly formed capillaries. Transmission and scanning microscopical investigations revealed neointima, neomedia and neoadventitia formation in 3--4 months. Complications such as obliteration were unfrequent. Aneurysm formation did not occur, the potency rate was satisfacory. Experience in 20 clinical cases are reported in detail. As to its usefulness in reconstructive vascular surgery, Solcograft is placed behind the saphenous graft. The graft is particularly suitable for patch plastics.

[Late results of reconstructive peripheral vascular surgery of the lower limbs].

The late results of the first 30 crural bypass operations are presented. The longest follow-up period was 6, the shortest 1 year. At the time of check-ups 14 of the bypasses were penetrable, and 16 were occluded. On 9 of the latter 16 amputation of the thigh had to be performed. Flow conditions and the problems of indication and contra-indication are discussed.

[Complications of aortoiliac surgery and their postoperative therapy].

Experience in early postoperative treatment of 249 patients who had been subjected to aortoiliacal vascular surgery is reported. The therapeutic principles are outlined and the complications are reviewed. For the prevention of infectious complications the patients are given antibiotic protection, are fed parenterally till passage starts and, to avoid threatening postoperative hypoxaemia in the case of more severe respiratory disorders, prophylactic respiratory therapy is applied, and small doses of heparin are administered to prevent thrombosis. Taking into consideration the high incidence of complications and the advanced age of the patients, it is important to keep these in the intensive ward during the early postoperative period.

[Late results of thoracic sympathectomy in various diseases].

The late results of 171 thoracal sympathectomies performed on 142 patients in the 20-year period 1952 to 1971 are described. Favourable results were achieved in Raynaud's disease, obliterating endarteritis and other occlusive vascular diseases, and also in hyperhidrosis.

[The innominate artery syndrome].

During to the peculiar morophology and symptomatology of the haemodynamic disturbance following occlusion of the innominate artery, the anonyma syndrome ought to be treated as an independent type of the cerebro-vascular syndrome. The anonyma syndrome is generally a part-symptom of obliterating arteriosclerosis of multiple localization and has therefore an unfavourable prognosis. After a brief survey of the literature the clinical data of patients operated for innominate artery occlusion are reported together with the surgical results.

[Radiation-induced changes of skin enzyme activity. II. Acid phosphatase, alkaline phosphatase].

After application of solf X-rays with 100, 500 and 1000 R, the activity change of the acid and alcaline phosphatase in the skin of mice has been studied. The studies happened immediatly after the irradiation and at the 1st, 2nd, 4th, 8th and 16th day. The measurment of the enzyme activity washable out of the skin and remianing in the skin after the washing and the total activity of the skin have been taken up. With the acid phosphatase it would be determined that the quantity washable out of the skin is unusually low; the acitity values of the wash solution increase at the 2nd day after the irradiation in dependence on the applicated dose;at the moment 0 after an irradiation with 1000 R, a significative activity increase in the wash solution appears; the homogenate activity at the 2nd day only gets a significative activity increase after the irradiation with 500 R. The alcaline phosphatase was measurable in the wash solution at no moment of the measurement. However, the alcaline phosphatase has been decreased in the homogenate with few exceptions.
