- Abstract:
- Objective To explore the efficacy of interstitial Nd:YAG photocoagulation for cavernous lymphatic malformations in children.Methods A retrospective review was performed for 18 children of cavernous lymphatic malformations from January 2018 to January 2019.Magnetic resonance imaging (MRI) and ultrasonography were performed for preoperative evaluations of affected areas.Nd:YAG laser was delivered through an optical fiber.Three sessions were required at an interval of 3 months.Elastic pant or bandage was applied under pressure to suppress tumor growth over 6 months after an initial treatment.The efficacy evaluations were made and other alternative treatments applied for cases of poor efficacy.The follow-up period was 1-2 years.Results Because the improvement of the lymphatic malformation was not obvious, there were 3 children who chose surgical treatment. In 15 cases, there were obvious changes, and no further enlargement, the effective rate was 83%. 6 cases with completely uncontrolled tumors were injected poly cinnamyl alcohol once six months to once year, among which 4 cases were 2 times, 1case were 3 times, 1 case were 4 times. Among the 10 cases with lesions located in limbs or armpits, the circumference diameter of 7 cases located in limbs was reduced by 3.7 cm on average, and the chest diameter of 3 cases located in armpits was reduced by 4.03 cm on average. And the average difference between the affected limb and the healthy side before treatment was 4.7 cm.After treatment, the mean was reduced to 2.23 cm. And the average difference between the affected armpit and the healthy side before treatment was 5.2 cm.After treatment, the mean was reduced to 1.17 cm.No further increase was found. Muscle strength was normal and activity of the limbs was not significantly abnormal. Conclusion Intralesional Nd:YAG laser photocoagulation is an effective and safe treatment for cavernous lymphatic malformations.
