History
Arteriovenous malformations (AVMs) are commonly misdiagnosed in infancy and childhood as an involuting hemangioma or capillary malformation because the lesion is not yet fast-flow, warm, or pulsatile.[7] AVMs may become more clinically evident during the second or third decade of life.[13, 10] Enjolras et al observed a progression during childhood to grade II in 84% of patients.[12] Puberty (32%), pregnancy (25% adult women), or trauma (20%) can trigger expansion.[4, 12, 1, 7] These lesions grow proportionately with the child and never regress.
Physical
The head and neck is the most common location (70%) for AVMs, with a higher incidence of intracranial lesions compared to extracranial lesions. This is followed in frequency by AVMs of the extremity, trunk, and viscera.[4, 1, 7] When fully developed, AVMs deepen in color with increased erythema, and local warmth, a palpable thrill, and a bruit. Patients with facial AVMs of the skin and/or facial bones may present with facial asymmetry, gingival hypertrophy, unstable teeth, periodontal bleeding, or skin/mucosal ulcers with secondary infection. Nasal AVMs may cause epistaxis. Bony AVMs create osteolysis (3/200 in the series by Enjolras et al).[12] Lower limb skin changes resembling curious dry, brown-violaceous plaques may appear and are known histologically as pseudo-Kaposi sarcomas.[1, 7] Distal extremity AVMs may lead to ischemia of the tips of fingers or toes associated with arterial steal and venous hypertension.
Later consequences of expanding AVMs with arteriovenous shunting include ischemic changes, indolent ulceration, intractable pain, and sudden life-threatening hemorrhage or recurrent, intermittent bleeding.[7] Increased cardiac output with subsequent congestive heart failure occurs in less than 2% of cases (5/200 in the series by Enjolras et al)[4] and usually in newborns with a massive AVM or in young adults with a large rapidly worsening AVMs in the limb or trunk.[1, 7]

| Stage | Description |
| I - Quiescence | Pink-bluish stain, warmth, and arteriovenous shunting are revealed by Doppler scanning. The arteriovenous malformation mimics a capillary malformation or involuting hemangioma. |
| II - Expansion | The description is the same as stage I, plus enlargement, pulsations, thrill, and bruit and tortuous/tense veins. |
| III - Destruction | The description is the same as stage II, plus dystrophic skin changes, ulceration, bleeding, persistent pain, or tissue necrosis. Bony lytic lesions may occur. |
| IV - Decompensation | The description is the same as stage III, plus congestive cardiac failure with increased cardiac output and left ventricle hypertrophy. |
