A comparison of proximal with distal arterial reconstruction in the treatment of advanced lower limb ischaemia.

Elective arterial surgery for lower limb ischaemia due to chronic occlusive disease has been performed in 212 patients over a five-year period. Of this group, 93 patients were treated for limb-threatening ischaemia. The remainder were treated for intermittent claudication. The clinical and haemodynamic responses to surgery are analysed in this series of 93 patients. The results of proximal reconstruction, in terms of a living patient with patent graft and functional limb, were significantly better (75%) at one year than in patients undergoing distal segment reconstruction (45%). Successful aortoiliac surgery was associated with a mean increase in the ankle systolic pressure index of 0.36, comparied with 0.46 in the distal reconstruction group.

Varihesive sealed dressing for indolent leg ulcers.

Forty-three patients with indolent leg ulcers that were resistant to a wide variety of treatment methods for an average period of 353 weeks, were treated by the application of sealed dressings with Varihesive (a compound of gelatin, pectin, sodium carboxymethyl-cellulose and polyisobutylene) a non-allergenic wafer which sticks to a moist surface. Varihesive dressings proved to be effective both in affording pain relief, and in allowing healing of 36 out of 43 ulcers (84%) in a mean time of 10 weeks. It is concluded that such a non-allergenic seal provides optimum conditions for reepithelialization of chronic ulcers and that Varihesive dressings are a valuable adjunct in the local treatment of skin ulceration.

Upper limb emboli: a reappraisal.

Upper limb embolus cannot be regarded as a benign condition, with invariable recovery due to copious collateral circulation. Gangrene of the upper limb may occur, as shown in the series of cases in this report. The overall mortality rate remains considerable, because of associated cardiac disease, recurrent embolism, or both. Emboli proximal to the origin of the profunda brachii artery represent a group associated with higher risk, for which prompt embolectomy is often indicated. In embolism due to subclavian aneurysm and with thrombosis, arterial reconstruction should be undertaken, for multiple recurrence is likely. Long-term anticoagulant therapy is usually required to try to prevent recurrence of embolism if the primary source of the embolus remains.
