Acetazolamide Loading Matas Test as a Preoperative Test for Internal Carotid Cavernous Giant Aneurysms

Spontaneous thrombosis of internal carotid artery: a natural history of giant carotid cavernous aneurysms.

OBJECTIVE To describe five cases of giant carotid cavernous aneurysms which evolved with spontaneous thrombosis of internal carotid artery (STICA), with emphasis at epidemiology, clinical presentation, natural history, related factors and neurological outcome. METHOD There were 711 consecutives patients with 802 aneurysms with and without surgical treatment during a period of 19 years. We sel...

Surgical treatment of large and giant cavernous carotid aneurysms

Cavernous carotid aneurysms (CCAs) are uncommon pathologic entities. Extradural place and the skull base location make this type of an aneurysm different in clinical features and treatment techniques. Direct aneurysm clipping is technically difficult and results in a significant postoperative neurological deficit. Therefore, several techniques of indirect surgical treatment were developed with ...

Polyarteritis nodosa presenting with bilateral cavernous internal carotid artery aneurysms.

A 24-year-old man was admitted with a severe, abrupt-onset headache and diplopia. On neurologic examination, movement of the left eye was limited in all directions, while the right eye was limited on lateral gaze. Cerebral angiography demonstrated bilateral aneurysms on the cavernous portion of the internal ICA, measuring 2.4 cm on the left and 2 cm on the right (figure, A and B). Abdominal ang...

Traumatic aneurysms of cavernous internal carotid artery with secondary epistaxis.

The syndrome of delayed epistaxis and monocular blindness following nonpenetrating head injury is reviewed. Bleeding results from rupture of a traumatic cavernous internal carotid artery aneurysm into the sphenoid sinus. There were 96 patients with this syndrome found in the literature and another four are added in this report. In 73% of the patients, the cause of the epistaxis was not apprecia...

Hypopituitarism caused by bilateral internal carotid artery aneurysms with a carotid-cavernous fistula.
