Venous Aneurysms – An Uncommon but Potentially Life-Threatening Disease: A Case Report

Computed Tomography Angiography (CTA) of the abdomen revealed dilatation of the vena cava and endoluminal thrombus.

Partial thrombosis of the vena cava in Magnetic Resonance Imaging (MRI).

Magnetic Resonance Venography (MRV): two vein aneurysms of the right sapheno-popliteal junction with endoluminal thrombus and maximum diameter 3.5–4.0cm.

Magnetic Resonance Venography (MRV): two vein aneurysms of the left popliteal vein with endoluminal thrombus and maximum diameter 1.5–2.0cm.

Complete ligation of the venous aneurysm.

Venous aneurysm of the right popliteal vein.

Aneurysmatectomy of the popliteal aneurysm, resection of the small saphenous vein (SSV) with preservation of the lateral branch of the popliteal vein.

Histopathologic examination: attenuation of the venous wall and replacement of its structures with fibrous connective tissue. (Trichrome Masson Stain).
