Rationale

The Malik 2023 systematic review provides evidence that the Schobinger stage is a prognostic indicator for treatment outcomes, specifically noting that higher stages (III and IV) correlate with increased recurrence and complication rates in head and neck AVMs. This adds clinical depth to the classification section by linking staging to procedural prognosis.

The Schobinger staging system for AVMsarteriovenous malformations (AVMs) classifies disease progression into four stages based on clinical presentation:\n\n*presentation:

* **Stage I (Quiescent):** warmth and cutaneous blush or pink-blue discoloration.\n*discoloration.
* **Stage II (Expansion):** enlargement with pulsation, bruit, and thrill.\n*thrill.
* **Stage III (Destruction):** pain, ulceration or bleeding, infection, and tissue ischemia.\n*ischemia.
* **Stage IV (Decompensation):** high-output cardiac failure. [@kohout1998]\n\nTreatment[@kohout1998]

Treatment urgency increasesand complexity increase with advancing stage. Higher Schobinger stages (III and IV) are associated with significantly higher rates of recurrence and complications following interventions such as embolization [@malik2023]. Stage IV disease often requires aggressive flow reduction prior to any resection to stabilize cardiac function. [@kohout1998]
