The role of the circle of Willis in carotid occlusion: assessment with phase contrast MR angiography and transcranial duplex.
To study the collateral pathways recruited after occlusion of the internal carotid artery (ICA), and to evaluate its influence on the impairment of hemispheric blood flow supply and development of low flow infarcts. ⋯ These data suggest that even though ICA occlusion may occur without cerebral damage, collateral blood supply is not enough to maintain normal hemispheric perfusion. The ACoA may be a key collateral pathway as a non-functioning ACoA is associated with an increased risk of developing low-flow infarcts.

Randomized Controlled Trial Clinical TrialA randomised, clinical study of the effect of low-dose dopamine on central and renal haemodynamics in infrarenal aortic surgery.
To determine whether dopamine prevents deterioration of central haemodynamics and renal function in aortoiliac surgery. ⋯ Peroperatively, dopamine counteracted depression of left ventricular function. The increased ERPF at the first postoperative clearance in the dopamine group indicates either improved peroperative haemodynamics or a synergistic effect between dopamine and epidural sympathetic blockade. Dopamine also improved diuresis and natriuresis.

Randomized Controlled Trial Clinical TrialEffects of spinal cord stimulation (SCS) in patients with inoperable severe lower limb ischaemia: a prospective randomised controlled study.
This study was designed to test the hypothesis that spinal cord stimulation (SCS) improves limb salvage in patients with inoperable severe leg ischaemia. ⋯ SCS provided long-term pain relief but limb salvage at 18 months was not significantly improved by SCS in this rather small study. The results suggest that SCS may reduce amputation levels in patients with severe inoperable leg ischaemia and be most effective in patients without arterial hypertension.

Comparative StudyThe changing workload of a surgical unit with a vascular interest.
To examine the changing relationship between general and vascular surgical workload on a vascular "firm", over a 6-year period. ⋯ Our figures show the progressive, rapid increase in vascular surgical workload, compared to general surgery, and the need for the continued expansion of vascular surgery as a speciality.

Multicenter StudyTrends in abdominal aortic aneurysms: a 13 year review.
To assess changing trends of abdominal aortic aneurysms 1979-1991. ⋯ The increasing incidence of abdominal aortic aneurysms may reflect better diagnostic methods, greater clinical awareness of the condition and increase in the proportion of elderly people in the population.
