Carotid endarterectomy for asymptomatic carotid artery stenosis: patients with severe bilateral disease a high risk subgroup.
(1995)
Journal - The Australian and New Zealand journal of surgery (AUSTRALIA )
Abstract :
Carotid endarterectomy if advised for asymptomatic disease must be associated with a low peri-operative morbidity and mortality and satisfactory long-term results. Over a 12 year period between 1978-1989 181 carotid endarterectomies were performed on 163 patients with asymptomatic carotid artery stenosis. There were 112 males and 51 females with a mean age of 64.9 years. All patients had a high-grade lesion (> 70% stenosis). The combined operative mortality and stroke rate was 2.8%. On long-term follow up six patients suffered a stroke. Only one patient however sustained a stroke in the same territory as the previously operated carotid artery. Four years following surgery 78% of patients were alive. Carotid restenosis or occlusion occurred in 8.3% of the remaining patients, all of whom were asymptomatic. All the immediate postoperative strokes occurred in patients with severe bilateral carotid artery disease. These patients with severe bilateral disease appear to constitute a high risk sub-group for peri-operative stroke. The role of 'normal pressure-hyperperfusion breakthrough' syndrome as the presumed aetiology of two of the postoperative cerebral haemorrhages is discussed.

Duodenal penetration by a Greenfield caval filter.
(1992)
Journal - The Australian and New Zealand journal of surgery (AUSTRALIA )
Abstract :
Duodenal penetration by a Greenfield filter occurred in a 77 year old woman 6 years after it had been inserted into her inferior vena cava. The reported incidence of complications associated with the Greenfield filter is low. We report a case of penetration of the device into the duodenum. Plain abdominal X-rays demonstrated angulation and deformation of the filter. Cavography and abdominal CT confirmed transcaval penetration of the duodenum. The patient had suffered from severe diarrhoea, night sweats and weight loss which resolved completely with operative removal of the filter.
