Endovascular interventions of juxtaanastomotic stenoses and thromboses of hemodialysis arteriovenous fistulas.

Purpose: To assess the primary and secondary patency rates for juxtaanastomotic stenoses, with or without superimposed thromboses, of arteriovenous hemodialysis fistulas treated with angioplasty and to compare it with National Kidney Foundation Dialysis Outcomes Quality Initiative treatment guidelines for stenosed and occluded arteriovenous fistulas (50% primary patency rate at 12 months).

Materials And Methods: This study was a retrospective analysis, covering a period of 5(1/2) years. Forty-three hemodialysis patients were referred due to secondary fistula dysfunction, and angiography was diagnostic of a juxtaanastomotic lesion.

MR angiography for abdominal and thoracic aortic aneurysms: assessment before endovascular repair in patients with impaired renal function.

Objective: The aim of the study was to establish the feasibility of using MR angiography as the sole imaging technique before endovascular repair of abdominal or thoracic aortic aneurysms and to compare preprocedural measurements by MR angiography and digital subtraction angiography in patients with impaired renal function.

Conclusion: MR angiography appears to be effective and reliable for use as the sole imaging method before endovascular repair of aortic aneurysms in patients with renal impairment.

Lower extremity amputations in chronically dialysed patients: a 10 year study.

Background: Lower limb critical ischemia is a major problem in dialysed patients.

Objective: To evaluate the results of revascularization procedures, amputations and prosthetic rehabilitation in dialysed amputees.

Methods: In this retrospective study we examined the charts of selected dialysis patients.
