Perfusion estimates and microvascular leakage (MVL) were recently correlated with glioma angiogenesis and aggressiveness, but their role in predicting outcome of patients (pts) with unfavorable low-grade gliomas (ULGG) is unclear. Their prognostic value was then investigated, versus conventional factors such as age, neurological status, tumor size, and(More)
PURPOSE The aim of this study was to present a 20-year experience with a single method of passive distal perfusion during descending thoracic aortic aneurysm resection. METHODS Aortic repair with a Dacron graft interposition was performed for 366 consecutive aneurysms located between the left subclavian artery and the crux of the diaphragm. The extent of(More)
Acute tamponade, although a rare manifestation of a descending thoracic aneurysm, was the dominant clinical feature of a classic type III dissecting aneurysm (arising distal to the left subclavian artery) in a 52-year-old man. High-quality aortography confirmed the diagnosis, ruling out any anomaly of the ascending aorta and the aortic arch. Surgical(More)
Paragangliomas arising in the suprasellar region are extremely rare. We report a case of suprasellar paraganglioma in a 47-year-old man who presented with amnesia and impaired visual acuity without any endocrine dysfunction. Magnetic resonance imaging (MRI) showed a large enhancing tumour in the suprasellar area. Following subtotal surgical excision, the(More)
From 1971 to 1980, 1292 patients with lung cancer were admitted to the Hôpital du Sacré-Coeur de Montréal. This diagnosis represented 0.5% of admissions in 1971 and 1.7% in 1980 (240% increase). Only 4% of patients were nonsmokers. Patients ranged in age from 30 to 93 years with a male to female ratio of 5.5 to 1. Of 414 cervical mediastinoscopies carried(More)
After endovascular coiling, several authors have reported refilling of the aneurysm, appearance of a mass effect, coils protruding into the parent artery, migration of coils into parent artery or through aneurysm wall, and compression of the parent artery by coil impaction. This is the first report of an endovascular coil transfixing a cranial nerve. We(More)
A 10-year experience in the surgical treatment of traumatic aneurysms of the descending thoracic aorta is reviewed. This series included 40 patients equally divided into two groups. Group I comprised 20 acute ruptures and group II, 20 chronic traumatic aneurysms, all situated at the aortic isthmus. The surgical repair was performed in all patients with a(More)
From 1975 to 1987, 19 patients (pts) were operated on for a traumatic lesion of the heart or of the ascending aorta. There were 15 males and four females with a mean age of 42 years. Twelve lesions (Group I) were penetrating and seven (Group II) blunt. Group I: Nine patients were in shock upon admission, including six with cardiac tamponade. Six pts were(More)
From July, 1974, to July, 1987, surgical treatment of descending thoracic aortic aneurysms was performed in 173 patients at l'Hôpital du Sacré-Coeur de Montréal. The cause of the aneurysms was arteriosclerosis or medial degeneration in 83 patients, trauma in 50, dissection in 34, and a congenital malformation in 6. A single method of external shunting(More)
