Uncovering the Hidden Threat: A Case Study on Superior Vena Cava Thrombosis

Superior vena cava (SVC) thrombus is a rare but potentially life-threatening condition where a blood clot forms in the superior vena cava, the vein carrying blood from the head, neck, and upper extremities to the heart. The incidence of SVC thrombosis is higher in patients with certain underlying me...

description Superior vena cava (SVC) thrombus is a rare but potentially life-threatening condition where a blood clot forms in the superior vena cava, the vein carrying blood from the head, neck, and upper extremities to the heart. The incidence of SVC thrombosis is higher in patients with certain underlying medical conditions, such as malignancy, heart failure, and chronic obstructive pulmonary disease. In this case study, a 36-year-old African American female with a history of essential hypertension, type 2 diabetes, end-stage renal disease, anemia of chronic disease, obstructive sleep apnea, obesity, and preeclampsia presented with sudden onset of confusion six days postpartum. The patient was admitted for further evaluation and treatment. Imaging tests showed an acute infarct in the left parietal lobe with no intracranial hemorrhage and an echo density/mass in the SVC consistent with a thrombus. Risk factors for SVC thrombus included pregnancy, a hypercoagulable state, and issues with catheter placement. The increasing use of intravascular devices such as indwelling catheters and pacemaker wires has been implicated in the rising incidence of SVC thrombus. Complete occlusion of the SVC is usually symptomatic and presents with a clinical picture similar to SVC syndrome. The importance of early detection and intervention was highlighted in this case, as the patient was initially asymptomatic after the onset of neurological symptoms. Treatment involved discontinuing heparin and starting the patient on Apixaban without a loading dose. This case study emphasizes the potential risk factors and complications associated with SVC thrombus and highlights the importance of early detection and intervention.
