A 17-year-old girl developed acute colicky periumbilical pain with haematuria. On examination a tightly elastic space-occupying lesion about 10 cm in diameter was palpable around the umbilicus. Erythrocyte sedimentation rate (ESR) was raised to 113 mm in the first hour. There was a microcytic anaemia (8.7 g/dl) and a positive Coombs test. Ultrasonography(More)
PURPOSE To prospectively assess the diagnostic accuracy of nonenhanced three-dimensional (3D) steady-state free precession (SSFP) magnetic resonance (MR) angiography for detection of renal artery stenosis (RAS), with breath-hold contrast material-enhanced MR angiography performed as the reference standard. MATERIALS AND METHODS The study was local ethics(More)
PURPOSE To report the results of preprocedural embolization of collateral branches arising from abdominal aortic aneurysms (AAA) scheduled for endovascular repair. METHODS Twenty-three consecutive AAA patients (all men; mean age 73 years, range 56-82) had coil embolization of patent lumbar and inferior mesenteric arteries (IMA) in a staged procedure prior(More)
PURPOSE To explore the use of telementoring for distant teaching and training in endovascular aortic aneurysm repair (EVAR). METHODS According to a prospectively designed study protocol, 48 patients underwent EVAR: the first 12 patients (group A) were treated at a secondary care center by an experienced interventionist, who was training the local team; a(More)
This study compares MRI and MDCT for endoleak detection after endovascular repair of abdominal aortic aneurysms (EVAR). Forty-three patients with previous EVAR underwent both MRI (2D T1-FFE unenhanced and contrast-enhanced; 3D triphasic contrast-enhanced) and 16-slice MDCT (unenhanced and biphasic contrast-enhanced) within 1 week of each other for endoleak(More)
Spontaneous dissection of the superior mesenteric artery (SMA) is rare and has been reported only sporadically. Therapeutic options are either a surgical approach, which is the more frequently adopted, or a simple observation. We report a case of spontaneous dissection of the SMA with a review of the literature and present a new therapeutic approach.
BACKGROUND Percutaneous transluminal angioplasty (PTA) of severely stenotic peripheral vascular lesions is hampered by a higher restenosis rate. The effects of PTA on vascular wall as well as the effects of the antirestenotic properties of endovascular brachytherapy (EVBT) remain unclear. MRI allows in vivo noninvasive assessment of the vascular effects of(More)
BACKGROUND For the detection of atherosclerotic lesions of the extracranial cerebral arteries, duplex ultrasonography (US) is an established operator-dependent method, whereas arteriography is associated with the not-insignificant risk of embolic complications. Spiral CT is a promising novel diagnostic tool that allows noninvasive, operator-independent(More)
