Insights
Complete superior vena cava occlusion from central venous catheters is rare. A novel combined angiographic/operative technique offers low-morbidity central venous access for these challenging thrombotic cases.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Critical Care Medicine
Background:
- Central venous catheterization is a common procedure.
- Thrombotic occlusion of the superior vena cava (SVC) is a rare but serious complication.
- SVC occlusion prevents conventional central venous access.
Observation:
- Three patients presented with complete SVC occlusion due to prolonged central venous catheter use.
- Conventional methods for central venous access were unsuccessful.
- Alternative surgical approaches like thoracotomy carry significant risks.
Findings:
- A unique combined angiographic and operative technique was developed.
- This technique successfully re-established central venous access.
- The novel approach demonstrated low morbidity in the treated patients.
Implications:
- This technique provides a viable solution for patients with SVC thrombosis.
- It offers a less invasive alternative to open surgery.
- Improved patient outcomes are expected in managing complex central venous occlusions.
Abstract:
Thrombotic occlusion of the entire superior central venous system is a rare complication of central venous catheterization. Three patients are presented with complete occlusion of the superior vena cava secondary to prolonged central venous catheterization. Thrombotic occlusion of the superior vena cava precludes central venous access by conventional techniques. Thoracotomy with direct catheterization of the right atrium and inferior vena cava cannulation represent alternative approaches but may be associated with significant morbidity. The present report describes a unique combined angiographic/operative technique designed to obtain central venous access with low morbidity in patients with occlusive thrombosis of the superior central venous system.
