Factors associated with early failure of arteriovenous fistulae for haemodialysis access.
The radiocephalic arteriovenous fistula remains the method of choice for haemodialysis access. In order to assess their suitability for fistula formation, the radial arteries and cephalic veins were examined preoperatively by ultrasound colour flow scanner in conjunction with a pulse-generated run-off system. Intraoperative blood flow was measured after construction of the fistulae. ⋯ The intraoperative fistula blood flow did not correlate with the outcome of the operation probably due to vessel spasm from manipulation. However, blood flow velocities measured non-invasively 1 day after the operation were significantly lower in fistulae that failed early compared with those that were adequate for haemodialysis. Most of the increase in fistula diameter and blood flow occur within the first 2 weeks of surgery.

Randomized Controlled Trial Comparative Study Clinical TrialRandomised controlled trial of percutaneous transluminal angioplasty for intermittent claudication.
To determine differences between PTA and conventional medical treatment in treadmill distance until onset of claudication, treadmill maximum walking distance, patient reported maximum walking distance, ankle brachial pressure index (ABPI), quality of life (Nottingham Health Profile, NHP) and Duplex measured extent of occlusive disease. ⋯ Only 10% of claudicants had discrete lesions suitable for PTA. Treatment of these patients with PTA produces a greater short-term improvement in walking and quality of life than medical treatment alone and is associated with less progression of disease.
