Preliminary experience with the Xtrak debulking device in the treatment of peripheral occlusions.

Purpose: To report our initial experience with a new rotary debulking device designed for treating long, diffusely diseased arterial segments.

Methods: Ten symptomatic patients (8 men; mean age 63 years, range 34-76) with occluded superficial femoral (n = 6) or popliteal (n = 4) arteries were enrolled into a study to evaluate the debulking capabilities of a rotational atherectomy device. Occlusion length ranged from 4.

Huge renal arteriovenous malformation mimicking simple parapelvic cyst.

The presenting symptoms of renal arteriovenous malformations are usually gross hematuria and hypertension. Herein we present an unusual case of huge renal arteriovenous malformation without these signs, but with ultrasound picture mimicking simple parapelvic cyst. Other imaging test, including Duplex ultrasound, computerized tomography and aortography, demonstrated that vascular lesion.

Acute upper-airway obstruction in a patient with achalasia.

The most common presenting symptoms of achalasia are dysphagia, recurrent regurgitation, and gradual weight loss. Surprisingly, many achalasia patients tolerate considerable esophageal distention without complaint. In very few cases is respiratory distress the only presenting symptom of achalasia.

Chilaiditi's syndrome in an infant: bowel loops mimicking mass lesions on sonography.

We report the case of a 6-month-old boy with Chilaiditi's syndrome presenting with tender hepatomegaly and abdominal pain. On sonography the interposed bowel loops mimicked a posterior hepatic or retroperitoneal mass. Although the majority of these cases may be radiological curiosities, patients can present with a variety of abdominal signs and symptoms.
