Microwave Ablation for Treatment of Vascular Malformations: Efficacy and Safety

Sponsor: Chengdu University of Traditional Chinese Medicine

Summary

This clinical trial aims to assess the safety and efficacy of microwave ablation in treating vascular malformations, including both venous malformations (VM) and arteriovenous malformations (AVM). Vascular malformations are abnormal clusters of blood vessels that can cause pain, swelling, and functional impairment, significantly affecting a patient's quality of life. Microwave ablation is a minimally invasive treatment that uses heat to shrink abnormal vessels, but its effectiveness and safety for these conditions need further investigation. The trial will enroll 150 patients (100 with venous malformations and 50 with arteriovenous malformations), all of whom will undergo a single session of microwave ablation. Ultrasound guidance will be used during the procedure to precisely target the lesions, while MRI will be used for both preoperative and postoperative evaluations to assess lesion size and track changes over time. The primary goals of the study are to determine whether microwave ablation can reduce lesion size and improve symptoms such as pain and swelling. Additionally, the study will monitor adverse events to evaluate the safety of the procedure, including any potential complications like infection, bleeding, or nerve injury. Patients will be followed for 12 months, with MRI scans taken at 1 month, 3 months, 6 months, and 12 months after the procedure to evaluate lesion shrinkage and monitor for any recurrence. Clinical symptoms will also be assessed at these time points to track improvement. This study could provide important data on the safety and efficacy of microwave ablation, potentially offering a less invasive treatment option for patients with vascular malformations.
