Autogenous arteriovenous elbow fistula for haemodialysis and upper extremity ischemia.

Background: The autogenous brachiocephalic or brachiobasilic arteriovenous elbow fistula is not considered to be only the secondary haemodialysis access. In patients with an unsuitable forearm vessel bundle, it is indicated as primary access and it is the method preferred to the fistula creation using a vascular prosthesis. Its rather rare complication is the development of upper extremity ischemia.

Peripheral venous hypertension after the creation of arteriovenous fistula for haemodialysis.

The function of an arteriovenous (av) fistula for haemodialysis may be complicated by manifestation of peripheral venous hypertension, which results from the arterial blood flow through the venous system into the periphery of the upper extremity. Its development is most typically caused by a proximal forearm av-fistula, as, in addition to the desirable arterialisation of the subcutaneous venous system of the arm, arterialisation of the venous system of the forearm and the hand may occur and possibly promote the development of venous hypertension, which may in the extreme result in gangrene of the fingers. Awareness of these problems as well as of the necessity of their surgical solution is essential for doctors dealing with haemodialysis.

Endovascular treatment of abdominal aortic aneurysms--6 years of experience with Ella stent-graft system.

Purpose: Evaluation of 6-year results of abdominal aortic aneurysm (AAA) treatment by Ella stent-grafts with regard to safety and effectivity in relation to morphology of the aneurysm.

Methods: From a group of 172 patients with AAA, in whom elective endovascular treatment was considered, 120 of them (69.8%) were found to be suitable for this type of therapy.

Endovascular treatment of central venous stenoses in patients with dialysis shunts.

Objective: Evaluation of long-term results of percutaneous treatment of central vein stenoses or occlusions in patients with haemodialysis shunt.

Materials And Methods: In 26 patients with haemodialysis shunts and confirmed central vein stenosis or occlusion, 28 primary percutaneous transluminal angioplasties (PTA) and 5 repeated PTAs (re-PTA) were performed; in three patients a stent was implanted - primary in one patient and due to early restenosis after PTA in two patients. To maintain stent patency, 10 re-PTA were performed.

Effect of various protective solutions on function after kidney transplantation.

Unlabelled: From 1995 to 2002 we monitored a group of 127 patients who had undergone kidney transplantations in the Olomouc transplantation centre. The aim of our study was to assess the function of the kidneys after the transplantation, which were rinsed during the removal from cadaverous donors and afterwards were treated by different preservative dilutions. We divided the patients into three groups of approximate similar size, according to the used dilution - EC (Eurocollins), HTK (Custodiol) and UW (Viaspan).

Venous hypertension following average arterious-venous fistula for haemodialysis.

The authors emphasize the need for the investigation of the central venous system prior to the insertion of an avfistula, this they consider to be of utmost importance in patients with anamnesis of central vessel access. After the av-fistula is inserted, an unrecognized obstacle (stenosis or thrombosis) may result in the occurrence of venous hypertension and hypofunction, this may lead to av-fistula malfunction.
