ISSVA Classification International Society for the Study of Vascular Anomalies VASCULAR ANOMALIES TUMORS Infantile haemangioma MALFORMATIONS Low-flow Fast-Flow Venous malformation (VM) Arterial malformation (AM) Capillary malformation (CM) Arteriovenous fistula (AVF) Lymphatic malformation (LM) Arteriovenous malformation (AVM)
Venous malformation • lesion composed of abnormal collections of veins • 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 http: //www. hopkinsmedicine. org/sebin/w/u/malformation_2. gif • mostly localized in the skin

V 9 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.
Aim of a study Analysis of the results of the treatment of venous malformations using foam sclerotherapy.
Material & Methods Retrospective analysis • 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 – 6 ml 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)

Foam sclerotherapy
Indications • Function impairment • Distortion of anatomical landmarks • Thrombosis • Pain • Cosmetic
Results 4 grade scale of clinical assessment Outcome Lesion regression Very good 80 -100% Good 60 -80% Moderate 20 -50% Without improvement <20%
Results 26% 53% 15% 6%
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.
Conclusions 1. VMs treatment is based on a proper diagnosis according to ISSVA classification, differentiating them from infantile hemangiomas. 1. Sclerotherapy with polidaconol used as foam is effective and safe managment of VMs.
