Insights
A man with a swollen leg had a tortuous left common iliac artery compressing his left common iliac vein, causing complete vein occlusion. This case highlights a rare cause of deep vein thrombosis.
Area of Science:
- Vascular Surgery
- Radiology
- Internal Medicine
Background:
- Deep vein thrombosis (DVT) can arise from various causes, including external compression.
- Iliac vein compression is a recognized but less common etiology of DVT.
Observation:
- A 48-year-old male presented with acute left leg swelling.
- Imaging revealed a tortuous left common iliac artery and a collapsed left common iliac vein.
- Venography confirmed complete left common iliac vein occlusion.
Findings:
- Abdominal computed tomography and aortography identified the tortuous left common iliac artery as the cause of extrinsic compression.
- The arterial tortuosity was compressing the ipsilateral common iliac vein, leading to venous stasis and thrombosis.
Implications:
- This case underscores the importance of considering arterial abnormalities as a cause of iliac vein compression syndrome.
- Accurate diagnosis through advanced imaging is crucial for appropriate management of DVT.
- Understanding rare vascular anatomical variations is key in diagnosing and treating venous thromboembolic disease.
Abstract:
A 48-year-old man admitted with the complaint of a swollen left leg. Abdominal computed tomography demonstrated a tortuous left common iliac artery and a collapsed left common iliac vein. Contrast left iliac venogram revealed complete occlusion of the left common iliac vein. Abdominal aortography showed a tortuous left common iliac artery, which was thought to be compressing the left common iliac vein.
