Thanks for your info. Do you know about any clinics in Germany using IVUS ?

Chronic cerebrospinal venous insufficiency (CCSVI) is a cerebrospinal venous disease that recently has been considered related to multiple sclerosis. Diagnosis may be performed by Doppler ultrasonography and angiography. One limit of angiography is the lack of visualization of venous wall aspects. We investigated in our study the usefulness of IVUS to detect CCSVI anomalies.
Material and Methods:
From September 2010 and January 2011, 13 patients with multiple sclerosis and CCSVI, evaluated by Doppler US, were enrolled in this study. Venography was performed through a left transfemoral retrograde access with 5 Fr introducer sheet. Venography and IVUS control was performed at ileo-lumbar level, bilateral jugulars and azygos vein.
All patients showed a stenosis of at least one vein. In all cases IVUS confirmed flebographic control. IVUS allowed to evaluate anomalous valve movement that was not evident at flebographic control in 5 patients (38%). 4 patients (31%) had an anomalous membrane of azygos vein. Moreover, a double lumen aspect was present in some cases.
IVUS is a useful device to detect venous anomalies in CCSVI. Particularly it allows a complete evaluation of valve movement that could not be performed with flebographic control. Moreover, it is fundamental to evaluate the Azygos vein structure that could not be showed clearly with US Doppler.
In this small study of 13 patients, IVUS was used to find stenoses that would not have been otherwise found in 38% of them.
