OBJECTIVES Intramural haematoma is defined pathologically as aortic dissection without an intimal tear. We therefore believe that this term is inappropriate as an acute clinical diagnosis, and instead, use the term 'thrombosed-type acute aortic dissection'. We compared the features of thrombosed-type acute aortic dissection with those of classic dissection. METHODS Thrombosed type was defined...

BACKGROUND We report a unique case of an acquired pial arteriovenous fistula occurring after an asymptomatic thrombosis of a superficial cerebral vein. CASE DESCRIPTION A cerebral angiogram performed in a 51-year-old man with subarachnoid hemorrhage revealed a 10-mm ruptured anterior communicating artery aneurysm and a thrombosed left superficial middle cerebral vein. Coil embolization of the...

Two patients with complete absence of light perception due to optic nerve compression were treated by decompressive procedures. Visual function progressively improved to the level of useful vision. A 42-year-old female with a partially thrombosed aneurysm in the right A1 of the anterior cerebral artery presented with right visual loss without light perception. The aneurysm was trapped and the i...

Spontaneous thrombosis of abdominal aortic aneurysm (AAA) is an uncommon condition. Chronic thrombosed AAA are related to occlusive iliac disease and often present with intermittent claudication. However, the symptoms related to expansion of the aneurysm and risk of rupture must be considerable, even in thrombosed aorta. We present our experience with three consecutive cases of chronic thrombos...

Nontraumatic or "spontaneous" acute subdural hematoma (SDH) is rare, and "pure" acute SDH without subarachnoid hemorrhage (SAH) due to aneurysmal rupture is extremely rare. We report a case of nontraumatic pure acute SDH caused by the rupture of a cortical middle cerebral artery (MCA) aneurysm. A 43-year-old man with no antecedents, except hypertension, presented to the emergency department wit...

Thirty-nine thrombosed arterial segments of the branches of the circle of Willis were studied by a complete serial section technique. Twenty-two patients had been hypertensive and 8 had hypercholesterolemia before the onset of cerebral artery thrombosis. The histological characteristics of the thrombosed arterial segments were intramural hemorrhage in 28 segments, superficial edema of the fibro...
