Síndrome de vena cava superior por trombosis de catéter venoso central

Abstract

Superior vena cava syndrome is a rare entity. The neoplastic etiology is the most relevant, as well as that related to invasive procedures with central venous catheter. A 32-year-old man consults the Emergency Department for sudden facial cyanosis, facial tightness, dry cough, odynophagia, dysphonia and vertigo without dyspnea. He presents colon neoplasia since 2019, with colostomy and left subclavian Port-catheter. At examination, facial and upper extremity edema, central cyanosis, multiple petechiae and nail bleeding on the hands. The angiotomography shows filling defect fort recent thrombosis in left internal jugular and brachiocephalic vein, right brachiocephalic vein, arch of the azygos vein and superior vena cava in its entire lumen. The surgical mechanical thromboaspiration allowed resection of the thrombus and restitution of circulation, with relative safety and low mortality.
