biostudies-literatureUnknown45(5)Yamashiro K<h4>Background and purpose</h4>Tumor embolization through the meningohypophyseal trunk and inferolateral trunk is known to be effective in skull base tumors; however, microcatheter cannulation into these arteries is difficult, and the number of cases that can be safely embolized is limited. In this study, we present a novel embolization procedure for the meningohypophyseal trunk and inferolateral trunk using the distal balloon protection technique and detail its clinical efficacy and complication risks. We developed this procedure to allow safe embolization in patients who cannot be adequately cannulated with microcatheters into these arteries.<h4>Materials and methods</h4>Patients who underwent meningohypophyseal trunk or inferolateral trunk embolization using the distal balloon protectioAJNR.
