Complications of Untreated Varicose Veins #3: Bleeding or Hemorrhage Caused by Vein Rupture
Untreated varicose veins are at a higher than usual risk of bleeding or spontaneous rupture. Over time, varicose veins become larger, and the vein wall becomes weak and stretched out. These veins, which are already weak are also under high pressure (because of venous reflux, or the ‘backflow’ and pooling of blood in these veins). As a result, the high pressure can cause the veins to spontaneous burst and bleed heavily. Because they are under high pressure, they bleed like an arterial bleed and patients describe the bleeding as ‘blood shooting across the room.’ The varicose veins that are susceptible are veins closest to the surface of the skin
Most patients describe that it occurs during or after a warm shower (warm water causes veins to relax and dilate, allowing more blood to pool within the veins) or during sleep. It is painless and patients report that they notice it because they feel something wet in bed. Patients who are on blood thinners can lose large amounts of blood, especially if it occurs while they are sleeping. Some people have required blood transfusions. The small blue spider veins around the ankle are equally at risk of rupture as are the larger bulging veins.
If someone you know has experienced bleeding from their varicose veins, they should be seen by a doctor. Treatment will prevent the veins from bursting again. This is a common condition that we see at La Jolla Vein Care.
