A prospective, randomized, blinded study was conducted to compare the use of a balloon catheter for performing hysterosalpingography (HSG) with the use of a traditional metal cannula. Sixty-one consecutive women who underwent HSG for evaluation of infertility were prospectively randomized to undergo the procedure with either a metal cannula (n = 31) or the balloon catheter (n = 30). The HSG pro...

BACKGROUND AND PURPOSE Concurrent temporary inflation of a nondetachable balloon in the parent artery has been reported to be useful during endovascular coiling of complex, wide-neck aneurysms, facilitating truer coil reconstruction of the native vessel. Nevertheless, there exists concern that adjunctive use of balloon assistance may lead to increased adverse events during aneurysm coiling. M...

conclusion the open-cell stent is effective and its performance is higher than that obtained with the closed-cell stent for treating central vein stenosis or occlusion in hemodialysis patients. results for the open-cell stent group, 159 patients were diagnosed as central vein stenosis and 98 were occlusion. for the closed-cell stent group, 78 were stenosis and 66 were occlusion. there were two ...

BACKGROUND We performed this study to semi-quantitatively characterize the formation of leptomeningeal collaterals in acute middle cerebral artery (MCA) occlusion caused by intravascular balloon inflation. METHODS The anatomic extent of leptomeningeal collateral blood flow from the anterior cerebral artery territory to the MCA territory during occlusion of the M1 segment was graded based on a...

Since 1973, the balloon catheter test with a Swan-Ganz, Dotter-Lukas or Fogarty catheter has been attempted in our department in cases of atrial septal defect (ASD) and patent ductus arteriosus (PDA) during cardiac catheterization and operation. Accurate informations concerning size, number and location of ASD were obtained during cardiac catheterization studies by using the balloon catheter. T...

Background and Objective: Balloon-assisted coil embolization has become an important adjunct in the endovascular treatment of intracranial aneurysms. The management of broadnecked cerebral aneurysms is technically perplexed due to a variety of factors, which include the difficulty in defining the aneurysm-parent vessel interface angiographically and problems in achieving complete aneurysmal occ...

A retrograde approach through the collateral channels is considered to improve the success rate of percutaneous coronary intervention for coronary chronic total occlusion (CTO). Various kinds of strategies and techniques are required to improve the success rate of this novel approach. We describe a case in which a CTO was successfully recanalized by the retrograde approach, using a new anchorin...

We have developed a model of reversible cerebral ischemia in a high-level nonhuman primate. By using endovascular techniques, the posterior cerebral artery is permanently occluded with coils, and the ipsilateral middle cerebral artery is temporarily occluded with a balloon. The balloon can be deflated and/or removed to reestablish flow at precise time intervals. Functional imaging of the brain ...
