Endoprosthesis placement

A hematoma was reported in one patient who underwent placement of a total endoprosthesis in the right knee. After three bolus infusions of rAHF-PFM, the adverse event resolved completely. The global assessment of efficacy was good at time of discharge, and no further adverse events were reported in this patient. 

Fig. 5.4a-c. A 74-year-old patient with mediastinal spread from bronchogenic carcinoma. The patient complains of superior vena cava obstruction symptoms, a Phlebography of the left upper limb shows narrowing at the confluence of the left innominate vein and the superior vena cava (arrowhead). Moderate reflux of contrast in mediastinal veins, b Phlebography of the right upper limb shows external compression of the superior vena cava by mediastinal tumor below the confluence of the innominate veins (arrow), c Cavography after placement of a Wallstent endoprosthesis (12 mm, 5 cm) demonstrates normal expansion of the superior vena cave at the site of tumor compression... 

Fig. 5.12a, b. A 71-year-old male patient with bronchogenic carcinoma invading the mediastinum and brain metastasis. Superior vena cava obstruction syndrome was treated by placement of a Wallstent endoprosthesis in the superior vena cava. At 3 weeks after endoluminal treatment, obstruction symptoms recurred, a Phlebography obtained by a femoral approach and catheterization of the stent lumen showed stent obstruction, and extensive filling of mediastinal veins, b After balloon dilatation at the junction of the stent with the internal jugular vein, a residual stenosis (arrow), due to insufficient stent covering of mediastinal tumor extent was evident...
