Right cerebellar stroke with a right vertebral artery occlusion following an embolization of the right glomus tympanicum tumor: Case report with literature review

Abstract

A 35-year-old female presented with episodes of frequent dizziness, ear fullness, and right ear tinnitus for 12 months. Head imaging revealed a right glomus tympanicum tumor. She underwent pre-operative endovascular embolization of the glomus tympanicum tumor with surgical, cyanoacrylate-based glue. Immediately after the procedure, she developed drowsiness and severe pain in the right temporal region. Further investigations revealed a right cerebellar stroke in the posterior inferior cerebellar artery territory. She was treated with intravenous heparin, followed by one year of oral anticoagulation. With rehabilitation, she significantly recovered from her post embolization stroke. However, the tumor was resected at another institution. Ten years later, follow-up imaging indicated a gradual increase in the size of the glomus jugulare tumor compressing the nearby critical vascular structures. She subsequently received radiation therapy to treat the residual tumor. Currently, she has no neurological deficit, but her mild dizziness, right ear tinnitus, and hearing impairment persist.

Jugulotympanic Paraganglioma With Preoperative Embolization That Led to Facial Nerve Paralysis and Surgical Rerouting of the Nerve

“…Embolization is performed 24-48 hours prior to surgery and though it is a quite safe procedure, it could result in severe complications [ 4 ]. Thus, it requires attention and anatomic knowledge of potential dangerous anastomoses between the tumor and the important vessels [ 8 ]. For residual paragangliomas, irradiation with a Gamma Knife® is the gold standard [ 1 ].…”

A cyanoacrylate/triethyl citrate/nanosilica-based closure glue with wet-adhesion capability for treatment of superficial varicose veins

“…In vivo use of cyanoacrylate-based medical glue has been approved in many countries, and the safety had been verified in clinical settings. 33,34 According to the purpose of our design, the polymer was intended to remain in the blood vessels to avoid any restoration of blood flow before complete vascular fibrosis. Several items in the FAL-006-treated sheep model were also detected to evaluate the safety of long-term stay in vivo.…”
