Creation of axillo-axillar bypass with bidirectional anastomoses.

Scholz and co-workers reported such type of anastomosis applied in femoro-crural bypass procedures which leads blood flow well into both directions. In vascular surgery practice of the author there were several occasions where this modified anastomosis was favorably applicable. An old man was operated up in this manner whose left common and internal carotid artery and the starting part of the subclavian artery was occluded that caused steal syndrome. Axillo-axillar bypass was done with end to side anastomoses. After the operation blood pressure increased to 155/75 mmHg on both arms the steal phenomena ended. Bidirectional anastomoses make flow from obtuse angle to rectangular.

About streamlined brachial dialysis shunts.

The authors modified the technics of fistula forming. In such cases where to create a connection on the forearm is impossible one possible modality is to make it between major vessels on the arm. Streamlined connection was made in seven patients between basilic vein and brachial artery in three cases, between cephalic vein and brachial artery in four. There were two men and five women. The age interval was between 58 and 78 years. The longest observation period is 30 months. Until this time the fistulas were suitable for dialysis and had abundant yield. Because of the number of cases and the observation period has not yet make possible to come to final conclusion their goal was to present technical solution first of all. Their expectation is that with making them streamlined they will manage to create good perfusing and long lasting fistulas.

[Surgical treatment of an unusual anomaly of the subclavian artery].

Surgical treatment of an unusual abnormality of the subclavian artery. The author presents a case of a 36 year-old female admitted with complaints of weakness of the right hand. Doppler pressure on the right and left arms was 100 mmHg and 140 mmHg respectively. Arteriography of the right subclavian artery showed a 6 cm-long tortuous area with a significantly narrowed (average 61%, maximum 75%) lumen. Other major arteries originating form the aorta did not exhibit pathological alterations. At surgery an 8 mm bore Goretex prosthesis was centrally anastomosed end-to-side to the common carotid artery, and the narrowed subclavian artery was ligated under the branching of the vertebral artery. A pedunculated end-to-end anastomosis was performed with the subclavian artery. The patient was released complaint-free. After a 4-year follow-up period the radial artery is palpable, the pressure in both extremities shows no alterations. The described pathology is regarded a congenital vascular alteration, which has never been described in the literature.

[Significance of the diagnosis and treatment of arterial injuries of the wrist].

Authors report on arterial injuries in a 2-year material of hand injured. The combination of injuries observed and the methods of treatment are described. Attention is called to the fact, that because of anatomical characteristics of these regions, the diagnosis of arterial injuries is not always easy. Four cases of their own are briefly described in whom the arterial injury could be stated only at the development of complications (pulsating haematoma, false aneurysm, later bleeding). The importance of the primary careful treatment and the significance of the examination of the circulation (Allen's test, Doppler) are stressed.

New surgical procedures for the management of carotid kinking.

Three new operative techniques for the management of the kinking of the internal carotid artery are reviewed. Method 1: Resection of the internal carotid artery, end-to-end anastomosis with patch-graft angioplasty. Method 2: In situ reimplantation of the internal carotid artery by grafting. Method 3: Shortening of the internal carotid artery by suturing and its dilatation by patch-grafting. The advantages and the conditions of application of these methods are reported. Their application is also recommended to others.

Laterally directed femoral bypass.

Femoral bypasses were established 7 times in 6 patients using venous autografts. The grafted veins were conducted in lateral direction along the territory of the femoral circumflex artery. The results and the advantages of the method are discussed. Considering the choice between lateral and the obturator femoral bypass, the former is recommended.

[The dacron-velour (Sauvage) prosthesis].

Dacron-velour (Sauvage) prostheses were implanted into 100 patients 2/3 of the implantation into the vessels of the lower limbs were absolutely indicated 3/6 were performed in combination with other reconstruction methods because of early or late re-obliterations. The prostheses were useful further for obturator, axillo-femoral (popliteal) and supra-aortic bridgings. The prosthesis is considered more advantageous than the traditional artificial veins in the same fields of application. Prosthesis is indicated in the femoro-popliteal section of no own vein is available of if this is not sufficiently long, and if no thrombendarterectomy can be performed or this is unsatisfactory. For bridgings down to the tibials combination of the prosthesis with an own vein can produce highly promising results.

Attempts at saving severely ischaemic limbs.

A distally produced arteriovenous fistula had a beneficial effect on the success of restorative arterial surgery in animal experiments. In two patients restorative vascular operation was supplemented with a distal arteriovenous shunt. In both cases, extremital function was preserved. In one patient the creation of a reversed venous circulation ensured a temporary result. Creation of an arteriovenous anastomosis, as an intervention improving the flow, and reversed venous circulation are recommended prior to amputation of otherwise incurable limbs. The progress in vascular surgery has resulted in a temporary or long-term preservation of more and more limbs which up to recent times had been condemned to amputation. The results are still unsatisfactory, as in a certain percentage of cases the success is only temporary.
