UNLABELLED Respiratory obstruction and stridor in infants and children are not uncommon. A rare cause of these sometimes life-threatening symptoms is the congenital saccular cyst. OBJECTIVES We present the case of a 5-year-old girl with a cervical tumor, which appeared after a laryngeal endoscopic surgery of a saccular cyst with two relapses and a particular local evolution of its recurrence ...

We investigated tissue responses to endoskeleton stent grafts for saccular abdominal aortic aneurysms (AAAs) in canines. Saccular AAAs were made with Dacron patch in 8 dogs, and were excluded by endoskeleton stent grafts composed of nitinol stent and expanded polytetrafluoroethylene graft. Animals were sacrificed at 2 months (Group 1; n = 3) or 6 months (Group 2; n = 5) after the placement, res...

Vascular imaging is an essential tool to appropriately diagnose and treat intracranial saccular aneurysms. There extensive heterogeneity in aneurysm characteristics including location, size, shape, patient demographics, clinical status that leads a great diversity both surgical endovascular treatment options. This variability may elicit confusion when deciding the most appropriate paradigm for ...

azygos vein aneurysm is a rare cause of a posterior or paratracheal mediastinal mass. trauma or conditions causing elevated flow or pressure in the azygos system, such as cardiac failure or cirrhosis of the liver are secondary causes of aneurysm of the azygos vein. we report a case of asymptomatic saccular aneurysm of the azygos vein in a 45-year-old man with blunt minor chest trauma. the azygos...

Adaptation in a vestibular organ, the bullfrog's sacculus, was studied in vivo and in vitro. In the in vivo experiments, the discharge of primary saccular neurons and the extracellular response of saccular hair cells were recorded during steps of linear acceleration. The saccular neurons responded at the onset of the acceleration steps, then adapted fully within 10-50 msec. The extracellular (m...

Non-traumatic multiple saccular aneurysms of the middle meningeal artery are extremely rare lesions. In our case the patient was a 51-year-old woman admitted with complaints of progressive headache. Magnetic resonance imaging showed a dilatation of the vein of galen malformation. Cerebral angiography revealed multiple saccular aneurysms of the middle meningeal artery and fistulous type of galen...
