Description Aim: The main objective of this work is to verify possibility of replacing the conventional angiography with high radiation dose by using MR venography in the evaluation of patients with Klippel-Trenaunay syndrome. This work is also including the elaboration of objective evaluation criteria for determining the severity of clinical finding and objectification of angiographic findings. Methods: Patients treated over the past 15 years were examined clinically and all of them undergone classical angiography. Clinical index, raising with the severity of clinical symptoms, was so determined. Main characteristics typical for KTS, especially dysplasia of profound and superficial venous system, hypertrophy of the main drainage vein and the presence of venous malformations were monitored within the angiography. Angiografic index growes with the severity of angiographic findings. Both indexes were compared reciprocally. It was expected that high clinical index was followed by high index of angiography, lower capillary malformation and increased risk of TEN in the history. In the second part of the study we try to find out whether MR venography examination can get the same results as conventional angiography. Results: During the reporting period 45 children has been diagnosed with Klippel-Trenaunay syndrome (26 boys, 19 girls). It has been shown that increasing clinical index correlated with growing angiographic score. Link of AG score and the size of capillary malformation has also been proven. Finally, a comparision of the results achieved by MRAG score and AG score for selected 20 patients showes that both methods can get the same results. Conclusion: This study presents statistically proven correlation between the severity of clinical symptoms and angiographic findings of patients with Klippel-Trenaunay syndrome. The second part of the study demonstrates the same sensitivity MRAG tests compared with conventional angiography. In the future this fact will enable to replace conventional angiography by MR venography completely and may save the patient from the radiation burden.
