Michał Kowalczyk Tutor: Assoc. Prof. Przemysław Przewratil MD, PhD Foam sclerotherapy in treatment of venous malformations in children. Department of Pediatric Surgery and Oncology Laboratory for Vascular Anomalies Medical University of Lodz

2 Venous malformation (VM)
ISSVA Classification International Society for the Study of Vascular Anomalies V A S C U L A R A N O M A L I E S TUMORS MALFORMATIONS Infantile haemangioma Low-flow Fast-Flow Venous malformation (VM) Arterial malformation (AM) Capillary malformation (CM) Arteriovenous fistula (AVF) Lymphatic malformation (LM) Arteriovenous malformation (AVM)

3 Venous malformation lesion composed of abnormal collections of veins
mostly localized in the skin can affect any other tissue or organ cutaneous and subcutaneous tissue muscles joints intestines most frequent low-flow vascular malformations may cause cosmetic or functional defects as well as physical disability

4 Venous malformations

5 Dubois and Puig Classification
Orthop Clin N Am 2006, 37,

6 Foam sclerotherapy A percutaneous injection of a sclerosing substance directly into a lesion. Prior to injection the sclerosing agent is mixed with air to make a foam. Sclerosant agent causes obliteration of the vessel, what effects in sealing off the blood flow. It may be administered as an only procedure or in combination with surgical resection. Multiple sessions are often required to achieve visual improvement or permanent results.

7 Aim of a study Analysis of the results of the treatment of venous malformations using foam sclerotherapy.

8 Material & Methods Retrospective analysis Foam sclerotherapy
34 patients treated between June 2006 and December 2011 20 female (59%), 14 male (41%) Age range: 1-15 (average 7 years) Foam sclerotherapy Polidocanol (Aethoxysclerol) 1% / 3% | 1 – 6ml Assessment by US, MRI Phlebography Performed prior to the sclerotherapy in 19 patients (56%) Surgical resection Preceded by sclerotherapy - 6 patients (18%) Duration of hospital stay – ranged from 1 to 5 days (average 2,5)

12 Phlebography Approach to the VM



15 Foam sclerotherapy

16 Indications Function impairment Distortion of anatomical landmarks
Thrombosis Pain Cosmetic

17 Results Outcome Lesion regression 4 grade scale of clinical assessment
Very good 80-100% Good 60-80% Moderate 20-50% Without improvement <20%

18 Results 26% % 15% %

19 Results Temporary side effects were observed in 2 (6%) patients.
Vasculitis – 1 case Skin necrosis – 1 case Initial phlebography increased significantly the effectiveness and safety of each sclerotherapy. In 6 patients (18%) sclerotherapy preceded the surgical resection improving their performance. Adopted method was rated by parents and patients as effective and hardly invasive.

20 Conclusions VMs treatment is based on a proper diagnosis according to ISSVA classification, differentiating them from infantile hemangiomas. Sclerotherapy with polidaconol used as foam is effective and safe managment of VMs.
