Percutaneous cryoablation of symptomatic venous malformations as a second-line therapeutic option: a five-year single institution experience

To report the mid-term outcomes of percutaneous cryoablation (PCA) performed as second-line therapeutic option of venous malformations (VM).
Material and methods
From 2011 to 2015, PCA was offered in 24 patients (mean age: 31 years, range: 12–64) as second-line treatment for recurrence of symptoms after sclerotherapy and when resection was not possible (due to lesion location or previous failure) or refused by the patient. Adverse effects were recorded, disease-free survival (DFS) and local tissue control (LTC) rates were calculated based on symptoms and volume evolution.
Mean follow-up was 18.7 months (6–48). Nine (37.5%, 9/24) adverse effects occurred and three (12.5%, 3/24) were severe. Mean pain assessed by visual analog scale (VAS) was 41.7 mm (0–80) before treatment and 20.3 mm (0–80) (p=0.01) after. Mean volume decreased significantly after treatment from 22.4 cm3 (0.9-146) to 8.35 cm3 (0–81.3) (p<0.001). Pain recurred in nine patients and size of one lesion increased. The DFS and LTC rates were 54% [95%CI: 22.94-77.27] and 93.33% [61.26-99.03] at 24 months, respectively. Only VM volume >10 cm3 was associated with a higher risk of local recurrence (p=0.05).
PCA as second-line treatment appears to be safe and effective for local control of VM according to mid-term results.
• Percutaneous cryoablation of venous malformations appeared well tolerated.
• Size of venous malformations decreased significantly after percutaneous cryoablation (p<0.001).
• Pain decreased significantly after percutaneous cryoablation of venous malformations (p=0.01).
