Application of multislice spiral CT and 3D reconstruction in diagnosis and treatment of vascular malformations in head and neck

Objective To explore the application of MS-CT and 3D reconstuction in diagnosis and treatment of vascular malformations in head and neck. Methods 20 cases with vascular malformations in head and neck underwent MS-CT and 3-D reconstruction. Then the treatment was determined based on the results of MSCT scanning. The postoperative results were evaluated. Results The images of MS-CT showed the edge of vascular malformations partially or completely in 16 cases of venous malformations. The lesion's anatomic site and 3-D position was obtained. The 3-D images also showed the overexpanded supply arteries in 4 case of arteriovenous malformations. 2 case of venous malformations in lip underwent resection and healed completely. 12 cases of venous malformations in buccal and floor of mouth were treated with compartmentalized sclerotherpy with partial lesion involution. 2 case of venous malformations in mouth floor were treated with operation followed by sclerotherpy with partial lesion involution. 4 cases of arteriovenous malformations were treated with Superselective Artery Embolization with partial lesion involution. Conclusion MS-CT and 3D reconstruction can play an important role in diagnosis and treatment of vascular malformations in head and neck.
