A nineteen-year-old female who had history of infectious endocarditis underwent surgical repair for ruptured aneurysm of sinus of Valsalva with aortic regurgitation. Through aortotomy mild degree of prolapse of right coronary cusp and perforation of left coronary cusp sized 6 mm in diameter were recognized and the latter was thought to be the dominant lesion resulting in severe aortic regurgitation. Following direct closure of ruptured aneurysm and patch closure of ventricular septal defect, perforated left coronary cusp was repaired with autologous pericardium. Post operative course was uneventful and she is now doing well.

A case is reported of malignant schwannomatosis (malignant transformation of von Recklinghausen's disease) with catecholamine production in a patient with multiple intracranial aneurysms. The patient had a history of episodic hypertension and elevated levels of catecholamines in the serum and 24-hour urinary excretion. Postmortem examination revealed diffuse central nervous system (CNS) dissemination of the tumor from the thoracolumbar spinal malignant schwannoma. A high concentration of catecholamines was demonstrated in the tumor tissue, and histochemical and electron microscopy studies suggested the presence of catecholamines in the cytoplasm of some of the tumor cells. This patient's clinical and radiological features, including severe headache, vomiting, stiff neck, ptosis of the eye ipsilateral to the internal carotid-posterior communicating artery aneurysms, and local arterial narrowing, mimicked those of subarachnoid hemorrhage from a ruptured aneurysm. However, the clinical picture was caused by diffuse CNS dissemination of the tumor, another primary malignant schwannoma of the oculomotor nerve, and intimal fibrous thickening of the arterial wall.

We report a case with ruptured aneurysm of the sinus of Valsava into the right ventricle, diagnosed during heart failure in a 22 years old patient. Etiology and prognosis based on our observation and the literature are discussed. Our patient benefited from clinical examination, ECG (15 derivations), pulmonary X ray and standard laboratory test. Pulsed-Doppler and contrast echocardiography have been realized with an ATL MK 600 echocardiograph. These data are discussed and compared to the literature. Cardiac examination revealed a continuous murmur predominantly diastolic 5/6 and an increase of peripheral artery pulsatility. Chest x-ray showed cardiomegaly and ECG bilateral atrial and left ventricular hypertrophy. Two-dimensional echocardiography revealed the diastolic prolapse of an aneurysmal right coronary sinus in the right ventricle. The rupture was confirmed by contrast echocardiography and pulsed-Doppler. Rupture which is a major complication of aneurysm of the sinus of Valsava, is the usual feature of detection. The consequences of rupture are heart failure and pulmonary edema. Our observation shows that conventional Doppler and contrast echocardiography are important for diagnosis and follow-up of aneurysm of the sinus of Valsava. Aortography, hemodynamic and angiocardiographic data, are also important for a precise diagnosis and the detection of associated malformations when pre-operative investigations of aneurysm of the sinus of valsava are needed.

We report a case of ruptured internal carotid artery aneurysm with contralateral oculomotor nerve paresis. A 69-year-old female experienced a sudden onset of severe headache. Left-sided mydriasis, absence of light reflex, disability of left ocular movement and ptosis were identified. Computed tomography scan revealed massive subarachnoid hemorrhage. Cerebral angiography showed a right internal carotid artery aneurysm. No abnormal finding was observed in the left internal carotid artery or basilar artery. Magnetic resonance imaging did not show thrombosed aneurysm. The oculomotor nerve paresis lasted for ten days. Ruptured right internal carotid artery aneurysm was surgically confirmed and repaired. We speculated that the contralateral oculomotor nerve paresis was the consequence of bloody jet flow from the ruptured aneurysm.

Carotid-cavernous sinus fistula is an arteriovenous fistula between the internal carotid artery and the cavernous sinus, and is usually caused by a traumatic tear or a ruptured aneurysm of the cavernous segment of the internal carotid artery. We describe a rare case of delayed intracranial haemorrhage and carotid-cavernous sinus fistula that presented 3 weeks after fracture of the facial bones. The patient developed orbital apex syndrome including ptosis of upper eyelid, pulsatile exophthalmos, chemosis, loss of ocular motility, monocular blindness on the right, and numbness of the right infraorbital region. After transcatheter intra-arterial embolisation, the ptosis and chemosis improved.

Epistaxis due to ruptured internal carotid artery (ICA) aneurysm embedded within a pituitary adenoma (PA) has seldom been reported in the literature. Here we want to elaborate the incidence, mechanisms, clinical manifestations, and treatment strategy for this condition. The first survived case of a patient with epistaxis and pituitary apoplexy due to ruptured aneurysm embedded within PA was reported and the literature was reviewed. A 53-year-old male patient presented to our institution with sudden onset epistaxis and progressive vision loss. Neurological examination revealed bilateral ptosis and dilated unresponsive pupils. A CT scan showed a large mass in the pituitary fossa with bony erosion. MRI revealed a large pituitary tumor and abnormal signal intensity in the tumor. No aneurysm was noted during the pre-operative MR angiography. Abundant arterial bleeding suddenly occurred during urgent transsphenoidal surgery. Digital subtraction angiography confirmed the presence of a 14 mm unexpected saccular aneurysm of right ICA in the cavernous sinus with the dome protruding into the sella turcica. Balloon test occlusion of the right ICA was undertaken and permanent occlusion was performed. The patient recovered well and received bromocriptine and thyroid hormone replacement therapy during the follow-up period. At 14-month followup, the patient had no neurological deficits, no features of ischaemia relating to the right ICA therapeutic occlusion. Our case indicated that epistaxis and pituitary apoplexy could be due to the rupture of an ICA aneurysm embedded in a PA. Clinical suspicion should remain high when evaluating any case of epistaxis and pituitary apoplexy. Optimal treatment should take into consideration individual features of the tumor, aneurysm, and patient. Making the correct diagnosis as well as identifying an appropriate management strategy is critical in the care of such patients.

We describe the case of an 83-year-old woman with left-sided ophthalmoplegia. She had no family history of connective tissue disease. The computed tomography study found a dilated left cavernous sinus. The conventional cerebral panangiography confirmed the diagnosis - a direct carotid-cavernous fistula (CCF), with no evidence of ruptured aneurysm. The woman underwent endovascular treatment with coiling of the cavernous sinus in combination with application of the Onyx embolic agent in the fistula. During the first 48 hours after the embolization the local pain, exophthalmos and conjunctival injection of the left eye were significantly ameliorated. The pulsatile tinnitus on the left disappeared and the ptosis of the left eyelid partially recovered. Selective angiography is the best method for the diagnosis and classification of CCF. Currently, treatment is possible with low mortality and morbidity rates. The endovascular intervention is able to completely occlude the fistula and maintain adequate blood fl ow through the carotid artery.
