Rare Palmar Digital Vein Thromboses Require Surgical Removal
Palmar digital vein thromboses, though rare, can cause unsightly lumps on the fingers. These blood clots, typically not injury-related, have several risk factors and require surgical removal.
Palmar digital veins, also known as volar digital veins, carry deoxygenated blood away from the fingers. They drain into a venous plexus over the thenar and hypothenar eminences, or into the dorsal venous network via intercapitular veins. There are three types of thromboses in these veins: varicose-like, non-inflamed, and superficial with inflammation. Injury to the fingers is a primary cause, but other factors like varicose vein conditions, venous stasis, thrombophilia, and systemic conditions increasing blood coagulability, such as autoimmune diseases or infections, also contribute.
When a blood clot forms, it appears as a bluish lump on the finger. Surgery is the usual treatment to remove these clots, as they rarely occur naturally in these veins.
Palmar digital vein thromboses, though uncommon, can be unsightly and require surgical intervention. Understanding the causes and risk factors can help in prevention and early detection.
