In an effort to isolate and characterize the emission of acoustic signals from saccular aneurysms, we made a series of invasive microphone recordings from experimental aneurysms created on the common carotid arteries of dogs using the vein pouch technique. Using a modified probe microphone, we compared recordings from the common carotid artery before creation of the aneurysm to recordings from ...

Aortic aneurysm is a chronic degenerative condition associated with atherosclerosis. Recent studies have revealed that angiotensin (Ang) II plays important roles in atherosclerosis. In this study, to investigate the relationship between aortic aneurysm and Ang II, we measured the activities of the angiotensin (Ang) II-forming enzymes, angiotensin converting enzyme (ACE) and chymase-like enzyme,...

BACKGROUND Cardiac abnormalities attributed to adrenergic surge are common after aneurysmal subarachnoid hemorrhage. Prescribed medications that block adrenergic stimulation may suppress the onset of cardiopulmonary compromise in patients after aneurysmal subarachnoid hemorrhage. OBJECTIVES To compare the incidence of early cardiac complications between patients who reported prescribed use of...

OBJECTIVE Terson's syndrome, a complication of visual function, has occasionally been reported in patients with aneurysmal subarachnoid hemorrhage (SAH), however the factors responsible for Terson's syndrome in aneurysmal SAH patients have not yet been fully clarified. In this study, we report on potential risk factors for prediction and diagnosis of Terson's syndrome in the earlier stage of th...

conclusion results reinforced the pivotal role of vascular geometry, with respect to hemodynamics, together with the importance of performing patient-specific cfd analyses, through which the effect of different blood flow conditions on the aneurysm hemodynamics could be evaluated. objectives this study aimed to investigate the effects of variations in heart rate and internal carotid artery (ica...

MR findings in a case of aneurysmal bone cyst of the temporal bone are described. MR can suggest the diagnosis of aneurysmal bone cyst and also give ancillary information that is helpful for surgical treatment.

Paediatric aneurysms are rare and represent the end result of a variety of different pathological mechanisms. They have a varied presentation and features that are distinct from their adult counterparts. The appropriate management of these aneurysms requires a multi-disciplinary team approach and detailed analysis to deal with the underlying pathology. This can involve the use of coils, adjunct...

BACKGROUND AND PURPOSE Knowledge about risk factors contributes to understanding the pathophysiological mechanisms that cause intracranial aneurysm rupture and helps to develop possible treatment strategies. We aimed to study lifestyle and personal characteristics as risk factors for the rupture of intracranial aneurysms. METHODS We performed a case-control study with 250 patients with an ane...

We report an unusual case of cerebral aneurysmal subarachnoid hemorrage (SAH) with Fabry's disease. A 42-year-old woman presented with aneurysmal SAH originated from a saccular aneurysm of the right posterior communicating artery. The patient was treated by an endovascular coil embolization of aneurysm. Postoperatively the patient recovered favorably without any neurological deficit. During her...

BACKGROUND Aneurysmal bone cyst was first described by Jaffe and Lichtenstein in 1942. Schajowicz in 1972 in his Histopathological Classification of Primary Bone Tumors (later modified by WHO in 1993) placed it in group IX - tumor-like lesions. Its etiology and pathogenesis is not completely clear. Aneurysmal bone cysts are usually found in older children and young adults, rarely before the age...
