[Thrombosis due to venous catheters--evaluation using CT]
Insights
Computed tomography (CT) effectively diagnoses and evaluates the extent of thrombosis caused by venous catheters. This imaging technique is a viable alternative to phlebography for critically ill patients.
Area of Science:
- Radiology
- Vascular Imaging
- Medical Diagnostics
Background:
- Indwelling venous catheters for therapy and parenteral nutrition are associated with thrombosis.
- Accurate diagnosis and assessment of thrombosis extent are crucial for treatment planning.
Observation:
- Computed tomography (CT) was used to investigate thrombosis in three patients with permanent venous catheters.
- CT imaging provided a clear diagnosis and reliable evaluation of thrombosis extent in all cases.
Findings:
- CT successfully identified severe thrombosis in patients with permanent venous catheters.
- The diagnostic accuracy and extent evaluation of venous thrombosis were confirmed via CT.
Implications:
- CT requires minimal contrast medium and is well-tolerated by severely ill patients.
- CT serves as a valuable alternative to phlebography for diagnosing and assessing large vein thrombosis.
Abstract:
Venous catheters for therapy and parenteral nutrition can cause thrombosis. A diagnostic elucidation and the evaluation of the extent of the thrombosis is indispensible for therapy decision. Besides phlebography, CT is a means for this. The results of CT-investigations of three patients with severe thrombosis caused by permanent venous catheters are shown. In all cases we were able to achieve the correct diagnosis and a reliable evaluation of the extent of the thrombosis. Small amounts of contrast medium are required and the investigation is tolerated even by seriously ill patients. CT therefore is an alternative to phlebography for the diagnostics and evaluation of the extent of thrombosis of the large veins.
