Embolization of Vascular Malformations in Head and Neck Regions

Abstract

<jats:p> The purpose of this study is to determine the effectiveness of embolization of each type of vascular malformation. </jats:p><jats:p> Thirty three patients with a diagnosis of vascular malformations in head and neck regions who were treated by embolization at Siriraj Hospital, Thailand, between 1997–2002 were reviewed retrospectively. There were 19 arterio venous malformations (AVMs), two arteriolar-capillary types, ten venous malformations, one veno-lymphatic malformation and one mixed capillary and venous types. The goal of treatment is to restore function and to prevent bleeding complications with particularly good cosmetic results. The technique and therapeutic agents depended on the types and flow characteristics of each malformation. Transarterial embolization with N-butyl cyanoacrylate were used in AVMs, unless no arterial route approach, then direct puncture was tried. This was carried out in five patients with AVMs. Polyvinyl alcohol was used in two capillary lesions. All venous malformations were treated by absolute alcohol injection, percutaneously. All had good outcome without serious complications. Two patients had further plastic surgery, one was AVM of eyelid and the other was facial venolymphatic malformation. Embolization is considered to be the primary treatment by eradication of those abnormal vessels directly at the target, whereas delayed plastic surgery may be needed later. </jats:p>

Interventional embolization combined with surgical resection for treatment of extracranial AVM of the head and neck: A monocentric retrospective analysis

“…Our results appear compatible with other publications. In studies where endovascular therapy was the sole treatment modality, or where endovascular therapy was combined with surgery, rates for "success" or "improved condition" ranged between 44% and 100% [10,11,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. We believe that the heterogeneity of reporting standards used by the studies outlined in…”

Multidisciplinary Approach to Treatment of High Flow Head and Neck Arteriovenous Malformations: Single Centre Experience in 7 Complex Cases

“…Usually, they are cosmetic problems, pain, bleeding, or ulceration. Selective angiography is better suited to characterize the nidus, flow pattern, and micro-or macroarteriovenous fistula before interventional therapy (5). Treatment of arteriovenous anomalies is generally known to be potentially dangerous, and sometimes the results are disappointing (4).…”

Endodontic implications of a patient with arteriovenous malformation: a case report and literature review

“…This focal swelling is frequently seen after angioembolization in AVMs, which gradually subsides in 1–2 weeks (Churojana et al . 2004, Wang et al . 2017).…”

“…This was attributed as a complication of angioembolization for which the patient was given antibiotics and kept under observation for the swelling to subside. This focal swelling is frequently seen after angioembolization in AVMs, which gradually subsides in 1-2 weeks (Churojana et al 2004, Wang et al 2017. Completion of root canal treatment was also delayed due to inaccessibility of tooth 15 and was resumed after sufficient mouth opening was restored.…”
