Preoperative Endovascular Embolization of Glomus Tumors; A Safe and Efficacious Adjuvant Treatment

Abstract

Objective: The aim was to evaluate the outcomes of preoperative endovascular embolization for glomus tumors including glomus caroticum, glomus jugulare, and glomus vagale.

Material and Methods: Between 2012 and 2017, eighteen patients with glomus tumors were diagnosed by angiography and some of them were embolized. Data were extracted for demographics, tumor subtype and size, embolization, and the rate of complication. The efficacy of tumor embolization was determined by comparing angiography before and after the intervention. Patients were followed-up for at least 24-48 hours for vital signs and possible complications.

Results: A total of 18 patients underwent diagnostic angiography and of these, tumor was embolized in 10 patients. Six patients had glomus jugulare, 1 had glomus vagale, 10 had glomus caroticum and 1 had concurrent glomus caroticum and vagale. The most common embolized artery was ascending pharyngeal artery with a rate of 50%. Post-embolization angiography revealed that blood flow to tumor had decreased at least by 70%. No complications related to the procedure were experienced in any of the patients.

Conclusion: Endovascular selective artery embolization prior to surgery is a safe and effective method in treatment of glomus tumors.

GLOMUS TÜMÖRLERİNİN PREOPERATİF ENDOVASKÜLER EMBOLİZASYONU; GÜVENİLİR VE ETKİN BİR ADJUVANT TEDAVİ SEÇENEĞİ

Abstract

Amaç: Glomus karotikum, vagale ve jugulare tümörlerinde preoperatif yapılan endovasküler embolizasyon işlem sonuçlarının değerlendirilmesi amaçlandı.

Gereç ve Yöntemler: 2012-2017 yılları arasında glomus tümörü nedeniyle 18 hastaya tanısal anjiyografi ve bazılarına da embolizasyon yapıldı. Hastaların demografik bilgileri, tümör tipleri, embolizasyon ve komplikasyon oranları analiz edildi. Tümör embolizasyonunun etkinliğine, girişim öncesi ve sonrası alınan anjiyografiler karşılaştırarak karar verildi. Hastalar girişim sonrası vital bulgular ve olası komplikasyonlar açısından en az 24-48 saat takip edildi.

Bulgular: Tanısal anjiyografi yapılan 18 hastadan 10’una eş zamanlı embolizasyon da uygulandı. Altı hastada glomus jugulare, 1 hastada glomus vagale, 10 hastada glomus karotikum ve 1 hastada eş zamanlı glomus jugulare ve vagale mevcuttu. En sık embolize edilen arter %50 oranı ile asendan faringeal arterdi. Embolizasyon yapılan hastalarda tümör kan akımında en az %70 oranında bir azalma meydana geldiği saptandı. Yapılan işlemler ile ilgili herhangi bir komplikasyon oluşmadı.

Sonuç: Endovasküler selektif arter embolizasyonu glomus tümörlerinin preoperatif tedavisinde güvenilir ve etkin bir yöntemdir.
