<p>The major vessels of the left lower limb were examined using gray scale and Doppler protocols. The exam was done from the groin to the dorsum of the feet.</p><p>The outlined femoral, popliteal, peroneal and both tibial arteries are normal in caliber colour flow and showed regular triphasic wave form. However, no evidence of athermanous plaque is seen.&nbsp;</p><p>There is dilatation and minimal compressibility of the left popliteal vein. Its lumen is partly filled by mixed echogenic material, filling about 80% of its lumen. The remaining corresponding veins as well as the superficial veins showed normal caliber, compressibility and wave form. The wave form of these veins were characterized by limited respiratory phasicity and positive augmentation responses.</p><p>Conclusion: Findings suggest the following:</p><p>1. Patent lower limb arteries</p><p>2. Sub-acute thrombosis of the left popliteal vein.</p>
