[True aneurysm of the deep femoral artery].

Aneurysms of the profunda femoris artery are very rare. The frequency of these aneurysms is 0.5-1% of all peripheral atherosclerotic aneurysms. This condition can be symptom free for an extended period of time. In one third of the patients, palpable, pulsating swelling appears in the groin. Complications such as rupture, peripherial embolism, deep vein thrombosis, depending on the condition of the arteries ischaemia in the leg can develop. Treatment of this condition according to the literature is resection of the aneurysm with reconstruction of the artery. Our practice is the same. If diagnosis is achieved surgery is necessary to avoid further complications. The literature review from 1960 presents 51 patients with the disease, we added 3 of our own cases to this number.

[The role of the V-Y plastics in vascular reconstructions directed to the deep femoral artery].

Because of the arteriosclerotic involvement of the superficial femoral artery, considerable part of the aorto-femoral reconstructions is performed with an anastomosis on the deep femoral artery. Stenosis of the deep femoral artery is usually limited to the bifurcation or to the first part of the artery; therefore the choice of treatment is desobliteration, or bypass below the bifurcation. This article describes a form of reconstruction which is suitable for direct endarterectomy of the deep femoral artery, without vein or plastic patch. The experience and advantages of this method are analysed.

[Successful surgical treatment of a multiple ruptured true saphenous vein aneurysm after an anterior femoro-tibial bypass].

Despite the fact, that we have been using the saphena magna as an autolog transplantatum for femoro-popliteal bypass since more than 50 years, the true aneurysma of the saphena graft is rare. Generally the aneurysma formations are detectable years after the primary operation, often in a life or limb threatening form. In our publication we report a successfully operated case of ruptured true saphena aneurysma. The multiplex aneurysma was operated on after a femoro-tibial anterior bypass operation, performed seven years earlier. The patient was normotensiv, without any laboratory sign of hyperlipidaemia. For the reconstruction we used autolog vein, from the upper limb.

[Surgical management of acute and chronic arterial occlusion].

Arterial occlusion may develop acutely and chronically, can affect any artery in the body. Surgical treatment of the disease is reasonable when definite symptoms occur. The forms of surgical treatment are: in acute arterial occlusion embolectomy or thrombectomy with Fogarty balloon catheter, under special circumstances in this group of patients we are compelled to use the typical surgical technique for chronic occlusion; the bypass and thrombendarteriectomy. Reconstructive operations are made most often on the lower extremities: thrombendarteriectomy or artificial prosthetic grafting on the aortoiliac section, autogenous saphenous vein bypass on the femoropopliteal section, and this is also the recommended procedure in the cases when the occlusive disease affects the crural arteries. Other operations in connection with occlusive arterial disease are lumbal and thoracal sympathectomy, fasciotomy and amputation at different levels. The recognition of occlusive disease on the extracranial carotid arteries are getting more and more common nowadays. The recommended operation in carotid occlusive disease is eversio endarteriectomy. Compared with the above the reconstructive operations of the mesenterial and renal arteries are rare. In the cases we do operate the operations are seldomly thrombendarteriectomies and more often bypasses with autogenous saphenous vein or artificial prosthetic grafts.

Gastrointestinal hemorrhage caused by secondary aorto-duodenal fistula: report of 5 cases.

Aorto-intestinal fistula is a late complication of reconstructive vascular operation, which is difficult to indentify. After the cessation of a massive, life-threatening bleeding, the best result can be expected from extraanatomical, axillobifemoral bypass. The authors treated 5 patients for fistula, developed following an aorto-bifemoral bypass. Diagnosis could be made before operation only in two of the cases. Axillo-bifemoral bypass was performed in 3 patients following the treatment of the fistula and the removal of the graft; 2 of their patients recovered.

Platelet function in male diabetics with and without macrovascular complications.

Changes of platelet aggregation in relation to macroangiopathy and to some of its risk factors were observed in microangiopathy-free, well-controlled type 1 diabetic males. Platelet aggregate ratio was generally lower in patients (n = 77) than in age-matched healthy subjects (n = 48). In the absence of cigarette smoking, hypertension, obesity and hypercholesterolemia (n = 25) in vitro platelet hyperaggregation was found induced with epinephrine, collagen or arachidonic acid, and to a lesser degree with ADP. There was no change in the presence of at least one risk factor in addition to diabetes (n = 29), but there was a further significant increase in platelet aggregation when overt coronary, cerebral or peripheral artery disease was present (n = 23).

[Results of vagotomy].

The authors present the clinical results of 558 patients, with peptic ulcer vagotomised between January 1966 and December 1977. Characteristic intraoperative and early postoperative complications of vagotomy were more frequent in the beginning. Best results were obtained by vagotomy and antrectomy or by vagotomy and pyloroplasty. Comparing the clinical results of vagotomy and partial gastrectomy (Billroth II) the authors found no significant difference.

[Embolism caused by a fiber from a synthetic vascular prosthesis].

Authors report on an embolization due to synthetic thread following inplantation of a vascular prosthesis, demonstrated by means of polarization optics in the spleen, corresponding to the dacron threads of the prosthesis. Complications of that type following vascular operations should be taken into account.

Structure of functioning saphenous venous grafts.

The changes developing in functioning saphenous vein transplants were studied by light and electron microscopy in three human cases. The degenerative signs appearing in the smooth muscle cells of the graft, as well as the glycogen accumulation and the changes of the cell organelles are discussed. Beside the thick elastic fibres visible under the light microscope in the graft functioning for 22 months the electron microscope revealed as a characteristic lesion the development of elastic fibres among the young collagenous fibres. It is emphasized that degenerated, sclerotic and varicose veins should not be used as grafts since no good results can be expected from them.
