Edema Fluid Can Be Successfully Evacuated from the Lymphedematous Limbs by Implantation of Silicone Tubings Bypassing the Site of Flow Obstruction Long-Term Observations.

Background: Lymphedema of limbs is caused by partial or total obstruction of lymphatic collectors. In advanced cases all main lymphatics are obstructed and tissue fluid accumulates in the interstitial spaces. The microsurgical lympho-venous shunts cannot be performed. We propose in such cases drainage of fluid accumulations by creating artificial flow pathways to the nonobstructed regions by implantation of silicone tubes. Aim: To present the 3 to over 6 year follow-up results of therapy by subcutaneous implantation of silicone tubes. Methods: In 150 patients with obstructive limb lymphedema after pelvic or axillary lymphadenectomy and irradiation in uterine or breast cancer or following soft tissue inflammation silicone tubes were implanted subcutaneously. Results: There was (1) immediate decrease of limb circumference within days after implantation; (2) in lower limbs in a 3-year follow-up a decrease in mid-calf circumference by a mean -8.7% (p < 0.05) with range of -3.2% to -31.0% corresponding to 90-900 mL volume and in the mid-thigh a mean -1.8% (p < 0.05) with range of -9.3% to +3% equal to 0-900 mL. In the upper limb in the 2-year follow-up the decrease in the mid-forearm was -8.5% (p < 0.01) with a range of -3.0% to -22.0% and in the mid-arm a mean -12% (p < 0.05) with a range of -7% to -22%. That corresponded to 180-700 mL volume for the limb; (3) decreased tissue stiffness; (4) maintenance of tubes patency on control lymphoscintigraphy, contrast opacification, and ultrasonography; and (5) lack of reaction to foreign body and effective control of inflammation at the site of implantation using low doses of benzathine penicillin. Conclusions: The technical simplicity of the surgical procedure, fast decrease of limb edema, and lack of tissue reaction to the implant make the method worth applying in advanced stages of lymphedema.

Consensus on Management of Deep Vein Thrombosis with Emphasis on NOACs (Non-Vitamin K Antagonist Oral Anticoagulants): Recommendations from Inter-Disciplinary Group of Indian Experts.

It is estimated that around 2.5 lac patients are identified as having an acute venous thrombo-embolic event in India annually. This includes patients with deep vein thrombosis and pulmonary embolism, and is estimated to result in more than 3.7 lacs deaths each year in European countries. The 'Consensus on Management of Deep Vein Thrombosis with Emphasis on NOACs (Non-Vitamin K Antagonist Oral Anticoagulants): Recommendations from Inter-Disciplinary Group of Indian Experts' position paper was developed to assist clinicians and institutions with an evidence-based approach to the diagnosis and treatment of acute deep vein thrombosis patients. Key to the evaluation of patients with suspected deep vein thrombosis is the use of the clinician's clinical evaluation with the help of pre-test probability tools as well as judicious use of objective diagnostic tests. Our hope is that we have supplemented clinicians' clinical acumen, and assisted them and their health systems in developing best practice approaches to this ever-interesting population of patients. The Deep Vein Thrombosis Consensus Working Group welcomes your inputs on how improvements might be made on this paper in the future.
