1/10. Spontaneous thrombosis of intracavernous internal carotid artery aneurysm and parent artery occlusion in patients with positive balloon test occlusion--two case reports.Two patients with giant intracavernous internal carotid artery (ICA) aneurysms were intolerant to balloon test occlusion of the ICA, and later developed spontaneous thrombosis of the aneurysm and the parent ICA without ischemic sequelae. Case 1: A 60-year-old female with a giant right intracavernous ICA aneurysm presented with right abducens nerve paresis. An unsuccessful extracranial-to-intracranial bypass graft operation was complicated by transient postoperative ophthalmoplegia. The patient did not tolerate balloon test occlusion of the right ICA after attempted bypass surgery, and was treated conservatively. The patient presented with acute onset of headache 3 years later. Case 2: A 50-year-old female with a giant right intracavernous ICA aneurysm presented with right abducens nerve paresis. The patient was managed conservatively after a positive balloon test occlusion of the right ICA. The patient suffered transient hypopituitarism and acute onset of headache 2 years later. Spontaneous thrombosis of the aneurysms and occlusion of the parent ICA were found in both patients. Neither had major hemispheric infarcts, but the first patient had asymptomatic infarcts, which were presumed to be thromboembolic in nature. patients with intracavernous ICA aneurysms who have positive balloon test occlusions appear to develop tolerance to spontaneous and gradual occlusion of the ICA without significant sequelae. However, these patients have an increased risk of developing embolic infarctions. The role for anticoagulation and repeat hemodynamic tests remains unclear.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/10. Spontaneous thrombosis of a giant intracavernous internal carotid artery aneurysm and ipsilateral internal carotid artery occlusion.A 75-year-old man who had suffered from right visual disturbance for 10 years suddenly experienced right cavernous sinus syndrome. magnetic resonance imaging revealed a giant thrombosed aneurysm in the right cavernous sinus extending to the right middle cranial fossa. Digital subtraction angiography disclosed occlusion of the right internal carotid artery at the petrous portion and good cross filling in the right-sided circulation through the anterior communicating artery. There was no filling of the aneurysm. In this case, the mechanism of parent artery occlusion is unclear, but direct compression and stretching of the parent artery by the aneurysm may be involved.- - - - - - - - - - ranking = 1.6666666666667keywords = giant (Clic here for more details about this article) |
3/10. Spontaneous thrombosis of a giant internal carotid aneurysm in a patient who presented with hypopituitarism.This case report describes a 66-year-old woman who initially presented with features of hypopituitarism secondary to a giant intra-cavernous internal carotid aneurysm. She represented a year later with features suggestive of a subarachnoid haemorrhage, but repeat CT showed no change from the one performed previously. A repeat angiogram, however, showed complete spontaneous thrombosis of the aneurysm including the parent artery.- - - - - - - - - - ranking = 1.6666666666667keywords = giant (Clic here for more details about this article) |
4/10. hypopituitarism and amenorrhea-galactorrhea syndrome caused by thrombosis of both internal carotid artery and giant intrasellar aneurysm: case report.Giant intra and parasellar aneurysm with a spontaneous thrombosis of internal carotid artery is rare. We report the case of a 34 years old woman presenting a unique giant sellar and parasellar aneurysm associated with hypopituitarism and amenorrhea-galactorrhea syndrome. Computed tomographic scans and magnetic resonance images were suggestive of a sellar tumor with a cystic component. Digital cerebral angiography showed spontaneous thrombosis of a intrasellar and parasellar carotid artery aneurysm and left internal carotid artery in the neck. A transseptal endoscopic biopsy was done and confirmed a thrombosed aneurysm. No other surgical treatment was required in this patient but permanent endocrinological treatment was necessary.- - - - - - - - - - ranking = 1.6666666666667keywords = giant (Clic here for more details about this article) |
5/10. Thrombosed giant intracavernous aneurysm with subsequent spontaneous ipsilateral carotid artery occlusion.We report a case of a 47-year-old man with a giant thrombosed aneurysm of the right cavernous internal carotid artery who initially presented with headache, double vision and trigeminal numbness. He experienced subsequent asymtomatic proximal occlusion of the parent vessel, revealed by follow-up angiography. This case illustrates the possibility that a giant thrombosed aneurysm may exert enough compression upon the parent vessel to induce flow stasis with resultant intraluminal thrombosis progressing to occlude the entire parent artery.- - - - - - - - - - ranking = 2keywords = giant (Clic here for more details about this article) |
6/10. Giant intrasellar carotid aneurysm - an unusual cause of panhypopituitarism.Carotid artery aneurysms represent a very rare cause of pituitary failure. We describe the case of a female patient harbouring a giant aneurysm of the left carotid artery that subsequently led to panhypopituitarism. Interestingly, the late postoperative course was complicated by severe hyponatremia, whose origin may have been due to inappropriate ADH secretion. This case illustrates the problems of diagnosis and postoperative handling of panhypopituitarism due to an intrasellar aneurysm.- - - - - - - - - - ranking = 0.33333333333333keywords = giant (Clic here for more details about this article) |
7/10. Spontaneous thrombosis of a giant intracranial aneurysm and ipsilateral internal carotid artery. Case report.Computerized tomography revealed a thrombosed giant intracavernous carotid aneurysm in a man who presented with ophthalmoplegia and headache. Angiography confirmed complete aneurysmal thrombosis and also revealed complete occlusion of the ipsilateral internal carotid artery. Aneurysmotomy and thrombectomy produced substantial reduction in mass effect, with symptomatic improvement. The spontaneous thrombosis of giant intracranial aneurysms is discussed.- - - - - - - - - - ranking = 2keywords = giant (Clic here for more details about this article) |
8/10. A thrombosed giant aneurysm of the internal carotid artery with brain stem displacement.A giant aneurysm with a maximum diameter of 5.2 cm arising from the right internal carotid artery grew to occupy the interpenduncular cistern and displaced the upper brain stem. Most of the lumen of the aneurysm was occluded by a thrombus and its real dimension in situ was visualized by CT scan. The neck of the aneurysm was successfully clipped but removal of the aneurysm was not feasible. Following surgery, clinical signs and symptoms gradually improved and subsequent decrease in size of the thrombosed aneurysm was documented by serial CT scans.- - - - - - - - - - ranking = 1.6666666666667keywords = giant (Clic here for more details about this article) |
9/10. Carotidynia: aetiology, diagnosis and treatment.The symptom of vascular neck pain, known as carotidynia, refers to throbbing pain of the neck and face with tenderness of the carotid artery. Recent publications suggest that carotidynia is a benign complaint, frequently associated with migraine, and often responding to migraine therapy. Past experience, and our own, indicates that carotidynia may be a symptom of other more serious disorders whose identification is essential to prevent subsequent catastrophic complications. 7 patients discussed in this publication presented with carotidynia. 4 have been reported previously. The associated disorders were dissecting aneurysm of the internal carotid artery (2 patients), long intraluminal clots with incomplete vessel obstruction of the internal carotid artery (2 patients), spontaneous aneurysm of the common carotid bifurcation (2 patients) and giant cell arteritis. We conclude that carotidynia is a symptom to be regarded with suspicion. The majority of patients encountered will have 'benign' carotidynia and angiography or exploratory surgery should not be routine. A rational approach to evaluation, investigation and treatment is presented.- - - - - - - - - - ranking = 0.33333333333333keywords = giant (Clic here for more details about this article) |
10/10. Mechanism of acute deterioration of the neurological status following rapid and massive intraluminal thrombosis in case of a giant intracavernous carotid artery aneurysm: demonstration by MR imaging.A case is reported of a thrombosed giant aneurysm of the intracavernous carotid artery. Transient neurological deterioration was attributable to the acute swelling of the aneurysmal mass after rapid and massive intraluminal thrombosis. Characteristics on the magnetic resonance imaging of this case are reported and discussed.- - - - - - - - - - ranking = 1.6666666666667keywords = giant (Clic here for more details about this article) |
