Severe skin reactions from interventional fluoroscopy: case report and review of the literature.

Some patients with certain preexisting health conditions may be at elevated risk for unusually intense radiation-induced skin reactions and late tissue damage from high-dose interventional procedures. The authors present a case report of a patient with mixed connective tissue disease and non-insulin-dependent diabetes mellitus who developed an unusual complication after placement of a transjugular intrahepatic portosystemic shunt. On the basis of a review of the literature, the following experiences may help identify patients at increased risk: previous high-dose procedures, connective tissue disease, diabetes mellitus, and homozygosity for ataxia telangiectasia.
