Vascular Lesion Embolization Imaging

Arteriovenous malformation in the foot. This is an example of an extensive form of arteriovenous malformation. In most patients, the lesions require aggressive treatment by means of surgical excision, transcatheter embolization, or both. The feeders arise from large-caliber foot arteries, and obvious arteriovenous connections (nidus) are seen. Most of these are centered in the midfoot. next info

    • Embolization may have 3 therapeutic goals:
      1. An adjunctive goal (eg, preoperative, adjunct to chemotherapy or radiation therapy)
      2. A curative goal (eg, definitive treatment such as that performed in cases of aneurysms, arteriovenous fistulae [AVFs], arteriovenous malformations [AVMs], and traumatic bleeding)
      3. A palliative goal (eg, relieving symptoms, such as those of a large AVM, which cannot be cured by using embolotherapy alone)
      Medical conditions treated by using embolotherapy can be grouped as follows:
      1. Vascular anomalies (eg, AVM, AVF, venous malformation [VM], lymphatic malformation [LM], and hemangioma)
      2. Hemorrhage (eg, pseudoaneurysms and GI tract, pelvic, posttraumatic, epistaxis, and hemoptysis bleeding)
      3. Other conditions (eg, tumors, varicoceles, and organ ablation)
