Sympathetic ganglionectomy is universally accepted as an effective and enduring treatment for primary hyperhidrosis. However, the variable extent of the ganglionectomy to treat this condition has been reported to be associated with a troublesome compensatory hyperhidrosis in between 22% and 81% of patients. In this prospective evaluation of a limited second(More)
Right aortic arch with complete isolation of the left brachiocephalic artery is an extremely uncommon anomaly of the aortic arch. This case reports the hitherto unreported association of the right aortic arch with isolated left brachiocephalic artery presenting with a subclavian steal syndrome detected in a 36-year-old female patient being investigated for(More)
Advances in optics, illumination and video-technology together with refinements in operative technique have made endoscopic transthoracoscopic sympathectomy (ETS) the method of choice for upper thoracic sympathectomy. Palmar hyperhidrosis is by far the main indication for ETS. The procedure is technically easy and well tolerated by patients, and(More)
The initial clinical observations and methods and results of treatment in 104 patients with subclavian (48), vertebral (four), and carotid (52) artery injuries are reported. Delayed hemorrhage ten days after misdiagnosed subclavian artery injuries resulted in false aneurysms causing compressive brachial plexus palsies. A conservative approach to penetrating(More)
Operative treatment of nonspecific aortoarteritis remains controversial and little information is available on the results of reconstruction of extracranial cerebral vasculature in this disease. Our experience with 25 patients with histologically proven symptomatic disease treated during a 4-year period is presented. The aortic arch and its branches were(More)
This study represents a prospective audit comparing carotid artery stenting (CAS) with carotid endarterectomy (CEA), performed by a single surgical team. Between January 2005 and December 2008, 440 patients were referred; 177 had CAS and 263 CEA. Selection of procedure was individualised and contra-indications for CAS included internal carotid artery (ICA)(More)
The management of 85 patients with penetrating injuries involving the external (n = 19), internal (n = 6) and common carotid (n = 46), vertebral (n = 10) and brachiocephalic (n = 4) arteries over a 5-year period in one hospital is reviewed. Sixty-three patients had no peroperative neurological deficit; 22 presented with localizing neurological signs. Where(More)
Experience with 147 operations for extracranial cerebral arterial reconstruction in 122 patients over a 36-month period is presented. The commonest condition in white, black and indian patients was atherosclerosis, although 8 of the 23 black patients had nonspecific aorto-arteritis (Takayasu's disease). Operations within the mediastinum included bypass from(More)
AIM To determine the mean carotid artery stump pressure (SP) at which patients develop neurological changes while undergoing awake carotid artery endarterectomy (CEA) under cervical block anaesthesia (CBA). METHODS A prospective analysis was carried out of patients undergoing awake CEA under CBA between February 2004 and April 2007. All patients had mean(More)
Explanations for recurrent sympathetic activity after an apparently successful sympathectomy are varied and often tenuous. Among the theories given for recurrent sympathetic activity are the development of alternate neuroanatomic pathways, the possibility of an incomplete operation (failure to appreciate an alternative anatomic pathway at the time of(More)
