case_images: A 21-year-old female with left facial AVM was presented with swelling left cheek. The swelling was associated with headache and episodic visual blurring in the left eye only. (A) Preprocedure photograph. (B) Selective left ECA angiogram revealed dilated anomalous vascular channels fed by the distal internal maxillary artery. (C) Postembolization angiogram using squid-18, showing total obliteration of nidus. (D) DSA after 9 months showing reconstitution of the previous channel through linguofacial trunk. (E) Roadmap. (F) Postembolization angiogram after the second session showing complete obliteration. (G) Follow-up after 2 years.

case_images: The second session embolization was done with squid-18 which lead to the complete resolution of symptoms, and the patient remained symptom-free over a 3-year follow-up period (Figure 1).

case_images: A 30-year-old female presented with a painful lump on the dorsum of her right foot which had been present for several years. In the past several months, it had become increasingly painful, and now, she walked with a slight limp. (A) Selective right foot angiogram showing shunting and rapid egress of contrast from the arteriovenous malformation through the anterior tibial artery and posterior tibial artery. (B, C) Superselective angiogram with microcatheter. (D) Superselective angiogram with microcatheter showing residual flow from posterior tibial artery. (E) Postembolization digital subtraction angiogram shows complete occlusion of the AVM with normal perfusion of the foot. (F) Therapeutic embolization, static fluoroscopic image shows squid filling the lesion.

case_images: A 45-year-old female with insignificant medical history presented with progressively increasing swelling involving, upper lip, left cheek, and left side of the mandible. (A) Preembolization photograph showing extensive growth involving left lower half of face and lips. (B) Computed tomographic angiographic reformat of the left mandible area showing enlarged vascular channels. (C) Selective left external carotid artery angiogram, lateral projection, showing AVM feeding by linguofacial trunk and internal maxillary artery. (D) Postembolization, left external carotid artery angiogram showing significant reduction in the flow of nidus. (E) Superselective angiogram with microcatheter during embolization showing squid cast.
