Development of the external carotid artery system including the middle temporal artery after direct-indirect revascularization surgery for moyamoya disease.

Background: The aim of this study was to clarify when and from which blood vessels indirect revascularization develops after combined revascularization surgery for moyamoya disease and how the donor vessels that undergo direct revascularization change in the medium to long term. In particular, we focused on the middle temporal artery (MTA), which has not received much attention in indirect revascularization surgery for moyamoya disease until now.

Methods: We targeted 20 sides that were suitable for evaluating the diameter of the external carotid artery system involved in combined revascularization surgery among moyamoya disease patients who underwent a composite revascularization procedure utilizing a 'U'-shaped skin incision encircling the parietal branch of the superficial temporal artery (STA) at our institution from 2018 to 2023.

Comparison of Foaming Properties Between the Shirasu Porous Glass Membrane Device and Tessari's Three-way Stopcock Technique for Polidocanol and Ethanolamine Oleate Foam Production: A Benchtop Study.

Purpose: To compare the characteristics of polidocanol (POL) and ethanolamine oleate (EO) sclerosing foams produced by a Shirasu porous glass membrane (SPGM) device with those made using a 3-way stopcock (3WSC).

Materials And Methods: Foam half-life times were measured in an ex-vivo benchtop study. Computed tomography (CT) images of each foam were obtained over the time course, and a CT texture analysis was conducted.

Successful Endovascular Repair of an Aortobronchial Fistula due to Takayasu Arteritis.

Endovascular approaches to treating a diseased ascending aorta are challenging. We report the use of an endovascular occlusion device for successful closure of a ruptured penetrating atherosclerotic ulcer of an ascending aorta. A 47-year-old female patient with Takayasu arteritis complained of a worsening hemoptysis.
