Successful endovascular embolization of an intralobar pulmonary sequestration.

Pulmonary sequestration is a congenital malformation characterized by dysplastic pulmonary tissue which receives blood supply by arterial systemic system, not in communication with tracheobronchial tree. Although it could be asymptomatic, it can also cause recurrent infections and hemoptysis, rarely massive and fatal. The conventional treatment consists in surgical resection of the pulmonary sequestration, but in the last few years endovascular embolization has been proposed as a valid therapeutic alternative.

Sclerotherapy of peripheral low-flow vascular malformations: technical aspects and mid-term clinical outcome.

Purpose: The therapeutical management of low-flow vascular malformations (LFVMs) is challenging because of high recurrence rate; multiple strategies have been proposed. This paper aims to report a single-center experience of direct puncture sclerotherapy of peripheral LFVMs, focusing on technical aspects and clinical outcome in mid-term follow-up.

Materials And Methods: 16 patients have been treated for peripheral LFVMs (mean age 36.

Improvement in accuracy of diagnosis of carotid artery stenosis with duplex ultrasound scanning with combined use of linear array 7.5 MHz and convex array 3.5 MHz probes: validation versus 489 arteriographic procedures.

Objective: Validity of a method to improve the accuracy of carotid artery duplex scanning was tested in comparison with arteriography.

Study Design: In 489 patients who had not previously undergone arteriography, 978 carotid arteries were examined with duplex ultrasound scanning. In method A, a linear array 7.
