Digital Ischemia during Sclerotherapy of an Arteriovenous Malformation

Vascular malformations (VMs) are usually treated conservatively until patients become symptomatic (i.e., pain, complications secondary to venous hypertension, neuropathy, and high-output cardiac failure). They are classified by either low-flow or high-flow characteristics ([Table 1]). Minimally invasive treatment methods are utilized to manage these lesions. The authors share a case utilizing a referenced method and noting an incidental risk/complication of a high-flow VM.

Table 1 Vascular malformation classification

Low flow	High flow
Venous malformation	Arteriovenous malformations
Lymphatic malformation	Arteriovenous fistula
Mixed venolymphatic malformation
Capillary malformation
