Abstract:
Acute superior vena cava (SVC) syndrome is managed by endovascular recanalization, venoplasty with stenting, and anticoagulation. It is often associated with central venous catheters. We present a case of a 55-year-old woman with acute SVC syndrome due to port-a-cath-associated thrombosis of the SVC and the brachiocephalic and subclavian veins who was treated with catheter-based thrombectomy and local spray thrombolysis, venoplasty, and stent placement. Port-a-cath restoration was achieved in the same session by endovascular snaring and repositioning. This case demonstrates that reoperation with surgical catheter removal and reinsertion of central venous catheters with possible complications (eg, rethrombosis, bleeding) can be avoided by single-session endovascular management.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
