CT diagnosis of catheter-induced septic thrombus of vena cava
Insights
Septic thrombosis of the vena cava, a rare complication of central venous catheterization, can involve gas-containing thrombi. Computed tomography is crucial for diagnosing these inflammatory conditions.
Area of Science:
- Vascular Surgery
- Radiology
- Infectious Diseases
Background:
- Central venous catheterization is a common medical procedure.
- Septic thrombosis of the vena cava is a serious complication.
- Early diagnosis is critical for patient outcomes.
Observation:
- Two cases of septic thrombosis of the vena cava were reported.
- Central venous catheters were implicated as the cause.
- Computed tomography (CT) was used for imaging.
Findings:
- CT revealed thrombi with gas bubbles in the venae cavae.
- Cases involved the superior vena cava and left inferior vena cava.
- Inflammatory changes were noted in surrounding tissues (mediastinum/retroperitoneum).
Implications:
- Highlights the importance of recognizing CT findings of gas in vena caval thrombi.
- Underscores the risk of septic thrombosis associated with central venous catheters.
- Emphasizes the need for prompt diagnosis and management of this condition.
Abstract:
Two cases of septic thrombosis of the vena cava induced by central venous catheterization are reported. Computed tomography showed thrombi containing gas bubbles in the venae cavae; one involving the superior vena cava and the other the left-sided inferior vena cava. Computed tomography also demonstrated surrounding inflammatory infiltrations in the upper mediastinum or retroperitoneum.
