Aneurysmal degeneration of the donor artery after vascular access.

Objective: This retrospective study analyzed the characteristics, potential risks, and therapeutic options of true aneurysms of the donor artery in arteriovenous fistulas (AVFs) for dialysis access.

Methods: We retrospectively collected data of patients with aneurysmal degeneration (AD) after AVF creation from surgeons who were members of the French Society for Vascular Access, treated from January 2006 to May 2011. The study excluded patients with pseudoaneurysms.

Endovascular treatment of immature, dysfunctional and thrombosed forearm autogenous ulnar-basilic and radial-basilic fistulas for haemodialysis.

Background: Forearm basilic fistulas are rarely used as vascular accesses for haemodialysis but they represent a valuable option when autogenous radial-cephalic fistulas cannot be performed. There is no information in the literature to date about the outcome of direct ulnar-basilic or transposed radial-basilic forearm autogenous fistulas after endovascular treatment of stenosis or thrombosis.

Methods: This retrospective study included 78 consecutive patients from eight dialysis units who were referred to a single interventional radiology centre for endovascular treatment of delayed maturation (n = 30), dysfunction (n = 35) or thrombosis (n = 13) of their autogenous forearm ulnar-basilic (n = 62) or radial-basilic fistulas (n = 16).

Percutaneous dilation of the radial artery in nonmaturing autogenous radial-cephalic fistulas for haemodialysis.

Background: Delayed maturation of radial-cephalic fistulas can be due to lesions of the radial artery that are amenable to percutaneous dilation.

Methods: Over a period of 7 years, 74 consecutive patients underwent angiography of an immature fistula that showed either stenosis or an insufficient enlargement of the radial artery that was treated by percutaneous dilation. Success, complications and secondary interventions were recorded according to consensus definitions.

[Giant parathyroid adenoma causing early recurrence of renal stones].

Primary hyperparathyroidism (PHPT) is not a rare disease. Renal stones are the most frequent complication of PHPT The authors report the case of a patient with giant parathyroid adenoma responsible for early recurrence of renal stones. Ultrasound examination of the neck, parathyroid MRI and Technetium99m-Sestamibi scintigraphy confirmed the parathyroid adenoma.
