Vasospasmus: Eine seltene Komplikation bei Homozystinurie

We report about a patient suffering from multiple spastic stenoses of varying degree of both iliac arteries and from occlusion of the left tibiofibular trunc. Laboratory investigations revealed increased levels of homocysteine and the diagnosis of homocystinuria was confirmed by fibroblast cell culture. The spasms responded well to vasodilative therapy with nitroglycerine, molsidomine (cGMP mediated) and prostaglandine E1 but not with nifedipine (Ca influx blocker). Our review of literature demonstrated that this arterial spastic abnormality is a very rare complication in patients suffering from homocystinuria.
