Thirty-seven patients undergoing femoropopliteal, fifteen undergoing femorodistal reconstruction and seven below knee amputees were subjected to prospective measurement of peripheral resistance. Resistance was significantly higher in the amputation and femorodistal groups than in the femoropopliteal group (P less than 0.03 and P less than 0.005 at 76 ml/min). In the femoropopliteal group patients with three vessel runoff had a significantly lower resistance than those with two or single vessel runoff (P less than 0.01). ⋯ Taking all the failed grafts there was a significant correlation between graft patency and resistance (P less than 0.003). Resistance measurement has been shown to correlate with the severity of the disease, with runoff defined radiographically and with graft patency. In a simplified form it may prove a useful adjunct to other methods of assessment in patients with distal disease.

Randomized Controlled Trial Comparative Study Clinical Trial
A randomized trial to compare single with multiple phenol injection treatment for haemorrhoids.
One hundred and twenty consecutive patients were entered into a randomized trial of single versus multiple phenol injection for the treatment of haemorrhoids. Follow-up at 3 and 12 months was available in 105 patients (56 in the single group and 49 in the multiple group). The results have shown that injection therapy, whether this be single or multiple, is an extremely effective form of therapy for patients with first or second degree haemorrhoids.
