While airway endoscopy and bronchoalveolar lavage are the methodsof choice for diagnosing exercise-induced pulmonary hemorrhage (EIPH), these techniques do not allow accurate evaluation of the severity of bleeding. EIPH pathology is characterized by occlusive remodeling of pulmonary veins. Affected veins have large collagen deposits in their walls, which reduces their ...

Vein of Galen Aneurysm malformation is one of the most difficult intracranial vascular lesions to manage. The difficulty in management of its shunts is aggravated by the hemodynamic effect and shunting reflected in the growing brain of infants and children. At present, the therapeutic options are widened by the opening ...

Endovascular treatment of peripheral artery occlusive disease has suboptimal long-term patency rates. The addition of cryoplasty to balloon angioplasty, which involves the application of cold thermal energy to atherosclerotic plaque, might improve outcomes and decrease the need for reintervention. At a single tertiary center, we retrospectively analyzed data from the ...

Because multiple intracranial aneurysms are not rare, accurate preoperative detection of asymptomatic aneurysms is important. In this paper, we report a ruptured distal anterior cerebral artery (DACA) aneurysm associated with an unruptured mirror-image aneurysm in a 62-year-old man presenting with headache. Although delayed vasospasm after subarachnoid hemorrhage has been reported ...
