- W48484498 abstract "Lymphatic malformations (LMs) are low-flow congenital lesions that consist of cysts of varying size. Sclerotherapy with intralesional bleomycin and OK-432 has been reported to yield dramatically beneficial results for this disorder. However, inflammation-related symptoms are often seen after treatment with these sclerosing agents. On the other hand, polidocanol (POL) is reportedly associated with fewer allergic and inflammatory reactions. Up to now, however, very few reports have documented the use of POL microfoam for treatment of LMs. This study was performed to assess the efficacy and safety of POL microfoam sclerotherapy for LMs.Between 2003 and 2016, cases were identified from a prospectively compiled database on low-flow congenital vascular malformations before undertaking a retrospective electronic chart review. Patients were included if they had LMs that had been treated by POL microfoam sclerotherapy. The location, size, and type of LMs were assessed using ultrasound and magnetic resonance imaging. Twenty-gauge venous catheters were inserted into the lymphatic space under ultrasound visualization. The LMs were then fully aspirated if they were macrocystic in form. Microfoam composed of 3% POL was then injected under ultrasound guidance. Microcystic LMs were treated by direct injection with POL microfoam under ultrasound guidance. The outcome was assessed by clinical examination combined with findings of postsclerotherapy imaging using ultrasound and magnetic resonance imaging.During a 13-year period, 32 patients met the inclusion criteria. These were 11 (34%) male patients and 21 (66%) female patients with a mean age of 18 years. The LMs were localized to the head and neck (47%), the trunk (38%), and the extremities (15%). The lesions were subdivided into macrocystic (56%), mixed macrocystic and microcystic (31%), and microcystic (13%) LMs. The average lesion size was 6.6 × 4.6 × 3.0 cm. The mean number of treatment sessions was 2.8 (range, 1-15), with a mean foam volume of 4.6 (range, 1-10) mL. Excellent (47%) and moderate (41%) responses were seen in 88% of the patients. Notably, half of the patients achieved excellent or moderate resolution with a single treatment session. Intralesional hemorrhage occurred in four patients (13%) but resolved spontaneously. Only one patient with mixed macrocystic and microcystic LMs developed post-therapy infection. However, the other patients did not develop any post-therapy inflammation-related symptoms, including fever, pain, and marked swelling.Percutaneous sclerotherapy using POL microfoam appears to be safe and effective for treatment of LMs. Ultrasound-guided POL microfoam sclerotherapy should be considered for such lesions, particularly those that are exclusively macrocystic." @default.
