linfovenosa

Linfovenosa is a term used to describe aspects of the interaction between the lymphatic and venous systems. In anatomy, it refers to lymphovenous junctions where lymphatic fluid drains into the venous circulation, typically at the point where the thoracic duct and the right lymphatic duct empty into subclavian veins.

In clinical and surgical contexts, linfovenosa often denotes lymphovenous shunts or anastomoses. These are microsurgical connections created to divert lymph fluid into the venous system, bypassing obstructed or damaged lymphatic pathways. The goal of such procedures is to reduce lymph buildup and edema, particularly in cases of lymphedema affecting the limbs.

Lymphaticovenous anastomosis (LVA) is a common lymphovenous procedure. It involves connecting small lymphatic vessels to nearby veins using supermicrovascular techniques. Planning and execution typically rely on imaging and intraoperative visualization to identify functional lymphatics and appropriate venous targets. Fluorescent imaging, such as indocyanine green, is often used to map lymphatic channels during the procedure. Outcomes vary and depend on disease stage, tissue quality, and patient-specific factors; some patients experience significant symptom relief, while others have more limited improvements.

Complications are generally related to the microsurgical nature of the procedure and may include infection, vessel thrombosis, or insufficient drainage. Linfovenosa remains a specialized area within vascular and lymphatic surgery, with ongoing research aimed at refining techniques and expanding indications.
