Sinus of Valsalva aneurysm rupture is a rare cardiac anomaly and demands prompt treatment. We present a case of a young patient who underwent transcatheter closure due to a ruptured sinus of Valsalva...
A 48-year-old woman underwent aneurysmectomy and primary suture repair with a pericardial patch for sinus of Valsalva aneurysm secondary to ankylosing spondylitis. The sinus of Valsalva aneurysm recur...
Multiple vascular accidents including rupture of a sinus of valsalva aneurysm, a minor ischemic stroke and intracranial arterial anomaly in a patient with systemic congenital abnormalities: a case report.
A 39-year-old man with a history of rupture of a sinus of Valsalva aneurysm experienced an ischemic stroke. Although the patient presented left-sided hemiparesis for a week, no abnormal signals were i...
Sinus of Valsalva aneurysm (SVA) is an uncommon anomaly of the aorta. Rupture of SVA often precipitates dramatic clinical complications, including heart failures. Right SVAs are the most common type,...
Hemodynamic instability was controlled in 27 patient during carotid stenting and it was showed that hemodynamic instability can be predicted by Valsalva maneuver before stenting and hemody...
The purpose of this trial is to assess whether the new endovascular repair technique of the abdominal aortic aneurysm (AAA) is an adequate substitute of the conventional AAA repair.
After endovascular abdominal aortic aneurysm repair, life-long follow-up is needed to monitor the effectiveness of exclusion of the aneurysm sac from blood flow. For this reason, aneurysm...
Hypothesis- Radiofrequency ablation, targeting the sympathetic input of the sinus node identified by 20Hz stimulation at the junction of the superior vena cava and the right atrium, will e...
The purpose of this study is to evaluate safety and performance of the Surpass Aneurysm-Embolization System.
Medical and Biotech [MESH] Definitions
The dilatation of the aortic wall behind each of the cusps of the aortic valve.
The formation of dentin. Dentin first appears in the layer between the ameloblasts and odontoblasts and becomes calcified immediately. Formation progresses from the tip of the papilla over its slope to form a calcified cap becoming thicker by the apposition of new layers pulpward. A layer of uncalcified dentin intervenes between the calcified tissue and the odontoblast and its processes. (From Jablonski, Dictionary of Dentistry, 1992)
Air-filled spaces located within the bones around the NASAL CAVITY. They are extensions of the nasal cavity and lined by the ciliated NASAL MUCOSA. Each sinus is named for the cranial bone in which it is located, such as the ETHMOID SINUS; the FRONTAL SINUS; the MAXILLARY SINUS; and the SPHENOID SINUS.
Aneurysm due to growth of microorganisms in the arterial wall, or infection arising within preexisting arteriosclerotic aneurysms.
Formation or presence of a blood clot (THROMBUS) in the SUPERIOR SAGITTAL SINUS or the inferior sagittal sinus. Sagittal sinus thrombosis can result from infections, hematological disorders, CRANIOCEREBRAL TRAUMA; and NEUROSURGICAL PROCEDURES. Clinical features are primarily related to the increased intracranial pressure causing HEADACHE; NAUSEA; and VOMITING. Severe cases can evolve to SEIZURES or COMA.
