Klippel-Trenaunay Syndrome: Case series from a university hospital of Nepal.

Klippel Trenaunay Syndrome (KTS) is a rare congenital malformation with capillary and venous malformations and soft tissue/bony overgrowth with or without lymphatic malformation. Cutaneous vascular stain, varicosities and tissue hypertrophy represent its main clinical features. Besides, the patient can develop thromboembolic pathologies, recurrent bouts of infection, stasis eczema, limb length discrepancy and intolerable pain typical of intraosseous involvement. Here, we report a case series of seven patients aged 10-45 who presented to our centre with clinical features suggestive of KTS. Out of them, six patients had involvement of unilateral lower limb, while only one had involvement of bilateral lower limb. They all had typical cutaneous vascular stains and underlying venous malformation, while one patient had developed complications with multiple ulcer formation. An interdisciplinary team of vascular surgeons, dermatologists, interventional radiologists, orthopaedics, and physiotherapists managed the cases. We performed an individualized treatment as per the patient's presentation, which included a combination of supportive, medical, interventional radiologic, and surgical interventions. The follow-up outcomes of all the patients revealed significant resolution of symptoms. Patients with KTS can have diverse presentations. Therefore, clinicians should ensure an individualized treatment with the involvement of a multidisciplinary team for proper management and prevention of complications.
