Vena basalis

Vena Basalis is a vein that is part of the human circulatory system. It is also known as the basilic vein, and it is a large, superficial vein of the upper limb that helps drain parts of the hand and forearm.

Anatomy

The vena basalis originates from the dorsal venous network of the hand. It travels up the back of the hand, crosses the forearm, and runs up the medial side of the upper arm. It then joins the vena mediana cubiti to form the axillary vein.

The vena basalis is important in the procedure of venipuncture, a common method for blood sampling. It is also often used for the insertion of a peripherally inserted central catheter (PICC) due to its large diameter and superficial location.

Clinical Significance

Due to its superficial location, the vena basalis is often used for intravenous therapy and blood draws. However, this can also make it susceptible to phlebitis, an inflammation of the vein.

In addition, the vena basalis can be affected by deep vein thrombosis (DVT), a blood clot that forms in a vein deep in the body. This is a serious condition because the blood clot can break loose and travel through the bloodstream to the lungs, causing a pulmonary embolism.
