Ho:YAG 레이저를 이용하여 제거한 하비갑개에 발생한 동정맥기형 1례

Abstract

Vascular malformations are rare vascular diseases composed of improperly connected vasculature. Arteriovenous malformations (AVMs), havening direct communication between artery and vein without capillary beds, are rare among all vascular malformations. Most AVMs are found intracranially, extracranial AVMs mostly affect the head and neck area. We report an unusual case of a 52-year-old female who was presenting nasal obstruction and diagnosed with AVM originated from the inferior turbinate as a final pathology. Preoperative selective embolization and complete excision of the tumor is the gold standard to treat AVM due to its rich vascular formation. As Holmium:yttrium-aluminium-garnet laser (Ho:YAG laser) is well-known for photocoagulation, hemostasis, and precise excision of tissue, we performed partial inferior turbinectomy with Ho:YAG laser without preoperative selective embolization. The patient was followed-up for four years and did not presented any other nasal symptoms. By this case, we propose that surgical excision with Ho:YAG laser without preoperative selective embolization is feasible for treatment of small AVM without invasion of adjacent tissue.
