Insights
A rare case of upper limb venous obstruction caused by subclavian vein valve hypertrophy was diagnosed using advanced imaging. Endovascular stenting successfully treated the condition, preserving venous circulation and highlighting effective management for rare venous diseases.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Interventional Radiology
Background:
- Upper limb venous outflow obstruction is uncommon.
- Primary subclavian vein valve hypertrophy is a rare cause of such obstruction.
- Accurate diagnosis can be challenging, leading to initial misdiagnosis.
Purpose of the Study:
- To report a rare case of upper limb venous outflow obstruction.
- To illustrate the diagnostic utility of advanced imaging techniques.
- To demonstrate the efficacy of endovascular treatment for this rare condition.
Main Methods:
- Case presentation of a 26-year-old male with suspected venous obstruction.
- Advanced Doppler ultrasound and Computed Tomography Venography (CTV) for diagnosis.
- Endovascular treatment utilizing Wallstent stents.
Main Results:
- Successful identification of subclavian vein valve hypertrophy as the cause of obstruction.
- Effective resolution of venous obstruction following endovascular stenting.
- Preservation of collateral venous circulation post-treatment.
Conclusions:
- Combined color Doppler ultrasonography is crucial for diagnosing unusual venous obstructions.
- Endovascular treatment offers a viable therapeutic option for rare venous conditions.
- Prompt and accurate diagnosis is essential for effective management of venous outflow obstruction.
Abstract:
This case report detailed a rare case of upper limb venous outflow obstruction due to primary subclavian vein valve hypertrophy in a 26-year-old male. Misdiagnosed initially, the condition was identified through advanced Doppler ultrasound and Computed Tomography Venography (CTV) Endovascular treatment using Wallstent stents effectively resolved the obstruction, preserving collateral venous circulations. This case highlights the importance of combined colour Doppler ultrasonography for diagnosing unusual venous obstructions and demonstrates the potential of endovascular treatments in managing rare venous conditions.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
