RESUMO
PURPOSE: To present a rare case of chronic total occlusion of the infrarenal aorta treated with a self-expanding endoluminal stent implanted without preliminary dilation. METHODS AND RESULTS: A 68-year-old woman presented with severe bilateral buttock and thigh claudication. Angiography revealed total occlusion of the infrarenal abdominal aorta and relatively normal iliac vessels. Via a right groin puncture and a 9-F sheath, a 14-mm x 5-cm self-expanding Wallstent was deployed in the abdominal aorta and expanded with an angioplasty balloon. Completion angiography showed successful recanalization of the aorta with satisfactory distal flow. Palpable distal pulses were restored, and the patient's symptoms were alleviated. She remained asymptomatic until her death from a major stroke 11 months after aortic stent implantation. CONCLUSIONS: Primary stenting may be considered a viable alternative to conventional surgery in selected patients with total infrarenal aortic occlusion.

We describe a 72-year-old woman with a false aneurysm of the mid-popliteal artery after a total knee replacement, presenting with a pulsatile swelling and an audible bruit in the popliteal fossa. The diagnosis was confirmed by duplex ultrasound. Surgical repair was undertaken using a saphenous vein patch to reconstruct the arterial defect. A false aneurysm of the popliteal artery following total knee replacement is an extremely rare occurrence. To our knowledge, only four other cases have been reported in the English-language literature.

Peliosis hepatis is an unusual disorder characterized by blood filled hepatic spaces. We describe the appearances of this entity on ultrasonography, computed tomography and magnetic resonance imaging. The importance of peliosis hepatis is that it may be an indicator of a treatable underlying condition.
