1/3. Surgery and stenting As combined treatment of a symptomatic tandem stenosis of the carotid artery.International co-operative studies have demonstrated a benefit from surgery for symptomatic and asymptomatic patients affected by internal carotid artery stenosis of 60-70%. The presence of a tandem lesion, intracranial or extracranial, may annul the benefit of surgery. Such patients may thus represent a challenging problem for management if age, good general conditions and a normal neurological status favour a therapy. A 54-year-old man developed transient ischaemic attacks of the left hemisphere; his general condition was good, and neurological status was normal. angiography showed a tight stenosis at the left common carotid artery near the ostium and at the homolateral carotid bifurcation. At first, a self-expanding wall stent was placed at the level of the common carotid artery stenosis, and immediately after a standard endarterectomy under general anaesthesia was performed. The postoperative course was normal and was complicated only by the presence of a mild deficit of the hypoglossal nerve due to the presence of a high bifurcation. The early and late outcome of our case suggests that stenosis of the proximal common carotid artery may be successfully treated by stenting. While awaiting additional data about this new technology, endovascular techniques and surgery may be complementary in the management of patients suffering from such tandem lesions.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/3. Transfemoral, transvenous embolisation of dural arteriovenous fistula involving the isolated transverse-sigmoid sinus from the contralateral side.Background: A dural arteriovenous fistula (AVF) involving the transverse-sigmoid (T-S) sinus which is occluded at its proximal and distal ends i.e., an isolated sinus, runs the risk of haemorrhaging or causing serious neurological deficits as a result of its retrograde leptomeningeal venous drainage. While lesions of this type have not been considered to be treatable by percutaneous, transvenous embolisation, this paper challenges this view. Case Presentation: Two middle-aged men with dural AVFs involving the isolated left T-S sinus presented with motor aphasia due to focal brain edema or haemorrhage. Under local anaesthesia, transfemoral, transvenous embolisation was performed with a microcatheter that was passed through the occluded proximal transverse sinus from the right (contralateral) side. The isolated sinus was then occluded with platinum coils. This embolisation resulted in angiographic and clinical cure of dural AVFs in both patients. Interpretation: Transfemoral, transvenous embolisation is a therapeutic alternative for the treatment of dural AVFs involving the isolated T-S sinus. Embolisation obviates the need for craniotomy and general anaesthesia, which are required for the established modes of treatment, i.e., direct surgery or direct percutaneous sinus packing.- - - - - - - - - - ranking = 2keywords = anaesthesia (Clic here for more details about this article) |
3/3. Transient ischaemic attack after spinal anaesthesia.A case of transient ischaemic attack lasting 6 h occurred after spinal anaesthesia with bupivacaine. The level of sensory block was satisfactory and there was no significant hypotension. We discuss the possible cause of this previously undescribed complication.- - - - - - - - - - ranking = 5keywords = anaesthesia (Clic here for more details about this article) |
