 Object. We wish to report our experience in the management of residual or recurrent intracranial aneurysm after previous endovascular or surgical treatment.  Methods. We performed a retrospective review of the clinical notes, operation records and cerebral angiograms of eighteen patients who were known to have undergone treatment for residual or recurrent(More)
 Background: We aimed to prospectively assess the usefulness of computer tomographic angiography (CTA) in streamlining the management of symptomatic intracranial aneurysms in a tertiary neurosurgical unit, from admission to surgery.  Methods: We performed a prospective evaluation over a 2-year period of all symptomatic intracranial aneurysms managed(More)
BACKGROUND Life-threatening massive hemoptysis requires prompt action and thoracic surgical input. Although there are a number of reports regarding each therapeutic modality for medical or surgical treatment, the significance of a multidisciplinary strategy remains undetermined. METHODS From January 1995 to December 2005, 120 patients were referred to our(More)
Over the past decade, uniportal video-assisted thoracic surgery (VATS) has evolved dramatically into a sophisticated technique capable of performing some of the most complex thoracic procedures. The idea of operating through fewer surgical incisions and, therefore, with potentially better cosmesis, less postoperative pain and paraesthesia, has led to(More)
Object. The treatment of 21 paraclinoid/ophthalmic segment internal carotid artery aneurysms (PCOSAs) over a seven year period in a regional neurosurgical center was reviewed to assess the degree of obliteration and recurrence rate of these aneurysms after treatment by surgical and endovascular methods. Method and result. An assessment of the clinical(More)
Dural transverse sinus arteriovenous fistulas with cortical venous drainage were associated with a high hemorrhagic risk. Dural transverse sinus arteriovenous dural fistulas could be treated by embolization (transarterial or transvenous), surgery or a combination of both. Transvenous packing of the diseased sinus was considered to be a less invasive and(More)
BACKGROUND In patients with bleeding peptic ulcers in whom endoscopic hemostasis fails, surgery usually follows. Transarterial embolization (TAE) has been proposed as an alternative. OBJECTIVE To compare the outcomes of TAE and salvage surgery for patients with peptic ulcers in whom endoscopic hemostasis failed. DESIGN Retrospective study. SETTING A(More)
A 51 years old lady presented with left lateral gaze diplopia of two-year duration. The clinical diagnosis of left abducent nerve palsy was made. There were no symptoms of facial numbness or ptosis. An MRI and MRA scan of the brain was performed. A large left internal carotid artery (ICA) aneurysm was demonstrated with an abnormal anterior and posterior(More)
Electromagnetic navigational bronchoscopy-guided biopsy of small pulmonary nodules can be challenging. Navigational error of the system and movement of the biopsy tool during its deployment adversely affect biopsy success. Furthermore, conventional methods to confirm navigational success such as fluoroscopy and radial endobronchial ultrasound become less(More)
Splenic involvement is not uncommon among patients with infective endocarditis (IE). These patients are susceptible to massive intra-abdominal haemorrhage resulting either from splenic rupture complicating endocarditis or from complication of major splenectomy. We report a patient with splenic haematoma complicating IE with progressive cardiac(More)
