A seven-month-old female child presenting with a large abdominal mass was found on investigation to have a duplex right kidney with a non-functioning obstructed upper moiety and a right ureterocele. The grossly dilated and tortuous upper moiety ureter presented as a large cystic mass on ultrasound and computed tomographic scans.

A 78-year-old man presented with recurrent left hemispheric transient ischaemic attacks. Angiography-wise and intraoperatively extreme internal carotid artery (ICA) coiling was noted with critical stenosis (Figs 1 and 2A). ICA bulb was transected, plaquebearing segment resected and ICA reimplanted onto endarterecomized carotid bifurcation (Fig. 2B). At 1-year follow-up, he is symptom-free with ...

We have studied the effect of i.v. metoclopramide on renal vascular resistance in nine healthy volunteers. Peak systolic and end-diastolic frequencies were measured using duplex Doppler ultrasound of a renal interlobar artery, before and after the administration of i.v. metoclopramide 10 mg, and the resistance index derived. There was no significant change in mean arterial pressure or resistanc...

We report a patient with calf pain induced by sport and exercise, initially thought to represent compartment syndrome, in whom MRI and duplex ultrasound ultimately revealed cystic adventitial disease of the popliteal artery. Surgical de-roofing of the popliteal artery resulted in complete resolution of symptoms with return to sporting activities.

Transcranial colour-coded duplex sonography (TCCS) is a new and non-invasive ultrasound application that combines both imaging of intracranial vessels and parenchymal structures at a high spatial resolution. This manuscript reviews the clinical applications of TCCS with focus on its diagnostic abilities in acute stroke patients. Furthermore, new experimental imaging techniques are discussed.

OBJECTIVES A duplex ultrasound study was performed to investigate morphological and hemodynamic patterns of carotid stenoses treated by endarterectomy with patch closure versus stenting. MATERIALS AND METHOD Twenty-nine carotid stenoses were treated with stenting and 65 with patch closure. Duplex ultrasound parameters (luminal diameter, mm; peak systolic velocity and end-diastolic velocity, c...

BACKGROUND AND PURPOSE We hypothesized that direct cervical investigation with Power M-Mode Doppler (PMD) combined with single-gate Doppler spectral analysis (SGDSA) using a 2-MHz pulsed-wave Doppler transducer would show reasonable accuracy parameters when compared with standard color-coded carotid duplex ultrasound (CDU). METHODS We prospectively screened for cervical internal carotid arter...

BACKGROUND AND PURPOSE The aim of this study was to determine the potential value of carotid artery calcification observed on plain radiographs in patients referred for carotid angiogram in the diagnosis of carotid artery stenosis. METHODS One hundred sixty consecutive patients with suspected carotid artery stenosis underwent both plain radiographs of the carotid arteries and digital subtract...
