Slow-Flow Vascular Malformations

Show Summary Details

Preview

Slow-flow vascular malformations include venous and lymphatic malformations. They can exist in any location except that lymphatic anomalies do not occur in the central nervous system. Each can cause disfigurement, discomfort and disability. Specific manifestations depend upon location and size. Anomalies of course, position, number and configuration can occur in main central veins including the vena cavae, portal, iliac, and renal veins. More typical venous malformations are globular spongy lesions. Venous lesions cause congestive pain and may present risk for thromboembolic phenomena. Those of the gastrointestinal tract can bleed. Lymphatic anomalies are prone to infection and leakage. Most are mass lesions of macro- or microcysts. Abnormalities of the central conducting lymphatic channels can cause chylothorax, chylous ascites, pulmonary dysfunction, chylous leaks through the skin and bony destruction.
