Percutaneous ethanol sclerotherapy for auricular arteriovenous malformation: Our experience with 11 patients

Surgical management of auricular arteriovenous malformations: A literature review

Auricular arteriovenous malformations (AVMs) can cause a variety of symptoms that seriously impact the patient's appearance, life, and mental well‐being. Surgery is the primary management method for auricular AVMs, but there is no consensus on how to surgically manage auricular AVMs. In this article, we document a comprehensive review of the characteristics, classification, and surgical interventions to treat auricular AVMs.

The Efficiency and Safety of Ethanol Sclerotherapy for Labial Arteriovenous Malformations

BACKGROUND

AND PURPOSE: Labial arteriovenous malformations, usually with accompanying cosmetic defects, pain, and bleeding, are aggressive with characteristics of high risk of recurrence and absence of effective treatment. This study presents a technique of sclerotherapy for labial arteriovenous malformations.

METHODS

Patients with labial arteriovenous malformations were treated with percutaneous ethanol sclerotherapy with or without polyvinyl alcohol particle embolization. The efficiency, complications, and recurrence rate were analyzed with imaging and clinical follow-up data.

RESULTS

Of the 15 patients, all patients received one or more treatment sessions, from which eight realized a cure (53.3%) and five had remission (33.3%). Two patients who did not achieve an effective result await further treatment. Four (26.7%) patients treated with ethanol sclerotherapy combined with polyvinyl alcohol particle embolization developed recurrence. No recurrence occurred in patients treated with only sclerotherapy (mean ± SD follow-up 17.2 ± 8.1 months). Thirteen patients developed transient complications: swelling, mild bleeding, and blistering. One patient had a postoperative scar of about 0.5 cm.

CONCLUSIONS

Ethanol sclerotherapy appears effective as a treatment for labial arteriovenous malformations. Careful application of the treatment can reduce the occurrence of complications.
