Comparison between KTS and PWSa
| Feature | KTS | PWS |
|---|---|---|
| Types of vascular malformations | Slow flow; capillary, lymphatic, venous | Fast flow; capillary, arterial, venous |
| Color of capillary stain | Red to purplish | Pink and diffuse; multiple capillary stains if RASA1 |
| AV fistulas | Insignificant | Significant |
| Marginal venous anomaly | Very common | Not found |
| Lymphatic vesicles | Present | Uncommon |
| Limb affected | Upper 5%, lower 95% | Upper 23%, lower 77% |
| Prognosis | Poor quality of life due to venous insufficiency and complications of lymphatic malformation; risk of pulmonary embolism | Progressive symptoms with cutaneous ischemia and possible heart failure |
