Technique, Efficiency and Safety of Different Nerve Blocks for Analgesia in Laser Ablation and Sclerotherapy for Lower Limb Superficial Venous Insufficiency - A Multicentre Experience.

INTRODUCTION: Laser ablation and sclerotherapy, as minimally invasive alternatives to surgery for varicose veins, have good efficacy, safety and cosmetic result. Some form of anaesthesia is generally used for pain control. AIM: To describe the technique and evaluate the efficacy and safety of femoral, saphenous and sciatic nerve blocks in isolation or in combination for analgesia during laser ablation and sclerotherapy for lower limb varicose veins. MATERIALS AND METHODS: In this prospective observational study, over a period of 33 months, in 856 limbs of 681 patients with varicose veins, ultrasound guided femoral, saphenous and sciatic nerve blocks for analgesia were performed in 769, 808 and 52 instances respectively; following which, endovenous laser ablation, sclerotherapy or combination of both were carried out using standard practice. After completion of the procedure, Visual Analogue Pain Scale (VAS) was used for pain assessment, and muscle weakness was assessed clinically. RESULTS: Nerve blocks could be successfully performed in all patients. Observed pain scores were 0 or 1 in 591 (69%), 2 or 3 in 214 (25%) and 4 in 51 (9%) legs with no score more than 4. Higher grades of pain were noted in femoral blocks during early stages of our learning curve. Mild to moderate muscle weakness was observed in 163 (2%) and 7 (13%) patients who underwent femoral and sciatic block respectively, which persisted for an average of two and a half hours and none beyond four and a half hours; saphenous nerve being a pure sensory nerve, did not cause motor weakness. CONCLUSION: For analgesia during laser ablation and/or sclerotherapy of varicose veins, ultrasound guided nerve blocks can be easily and quickly performed. They provide excellent pain relief and comfort to the patient and to the operator; and they do not cause any additional complication.

A rare case of male primary breast lymphoma.

Primary lymphoma of the breast is a rare occurrence because of the paucity of lymphoid tissue in the breast and is an even rarer entity in the male breast. Imaging, along with tissue diagnosis goes a long way in diagnosing breast lymphoma which has a significantly different management scheme than other breast neoplasms with respect to radio-chemotherapy rather than surgical resection. We present a case of primary male breast lymphoma which was evaluated with magnetic resonance imaging as well as other conventional imaging modalities and was treated by chemotherapy with a 7-month follow-up.
