Arteria tarsalis lateralis

Arteria tarsalis lateralis, also known as the lateral tarsal artery, is an important blood vessel located in the foot. In this article, we will provide a detailed overview of this artery, including its anatomy, function, and clinical significance.

Anatomy

The arteria tarsalis lateralis is a branch of the dorsalis pedis artery, which is itself a continuation of the anterior tibial artery. It arises from the dorsalis pedis artery just above the level of the ankle joint. From there, it runs laterally along the lateral side of the foot, supplying blood to various structures in this region.

Function

The main function of the arteria tarsalis lateralis is to provide oxygenated blood to the lateral aspect of the foot. It supplies blood to the lateral tarsal bones, the lateral metatarsal bones, and the surrounding soft tissues. This arterial supply is crucial for maintaining the health and function of these structures.

Clinical Significance

The arteria tarsalis lateralis can be affected by various pathological conditions, leading to potential clinical implications. Some of the notable clinical significance includes:

Foot Trauma

In cases of foot trauma, such as fractures or dislocations, the arteria tarsalis lateralis may be injured, resulting in compromised blood flow to the lateral foot. This can lead to tissue ischemia and subsequent complications if not promptly addressed.

Peripheral Arterial Disease

Peripheral arterial disease (PAD) is a condition characterized by the narrowing or blockage of arteries, usually due to atherosclerosis. The arteria tarsalis lateralis can be affected by PAD, leading to reduced blood flow to the lateral foot. This can result in symptoms such as pain, numbness, and non-healing wounds.

Surgical Interventions

During surgical procedures involving the foot and ankle, the arteria tarsalis lateralis may need to be identified and preserved to ensure adequate blood supply to the lateral structures. Surgeons must be cautious to avoid inadvertent damage to this artery during such interventions.
