Ultrasound in Medicine and Biology
Department of Physical Medicine and Rehabilitation, Presbyterian Medical Center, Soenam University College of Medicine, South Korea Objectives: Reduced physical activity and muscle atrophy is common in patients with femur fracture. The aim of this study is to assess whether immobilization after femur fracture surgery leads to atherosclerotic change in popliteal arteries. Methods: Thirty one patients who admitted for rehabilitation after surgical treatment of femur fracture (13 men and 18 women; mean age, 77611 years) were enrolled. We measured intima-media thickness (IMT) of popliteal artery in longitudinal and transverse plane bilaterally using ultrasound. And peak systolic velocity (PSV) was also evaluated by duplex-sono. Results: Interval between fracture and exam was 67660 days and 6 patients were taken total hip arthroplasty (including hemi-arthroplasty) and 25 patients were treated by internal pin fixation. Mean IMT of popliteal artery was thicker in the fracture side than in the non-fracture side (1.2160.90 mm vs 0.9360.68 mm) significantly (pp..05). However, PSV was increased significantly (102.2613.6 cm/s vs 94.664.9 cm/s) in patients with 1 month or more duration. Femur fracture and consequential immobilization affected popliteal artery IMT, and it was highly related to progression of atherosclerotic plaque formation. Conclusions: Femur fracture and consequential immobilization affected popliteal artery IMT, and it was highly related to progression of atherosclerotic plaque formation. PPT21-006 Sonographic Diagnosis of Takayasu’s Arteritis in a Pediatric Girl Wai Pong Chu, Peggy Tang, Wai Yee Lydia Chan Department of Radiology, Tseung Kwan O Hospital, Hong Kong Objectives: To illustrate the ultrasound features of Takayasu’s arteritis in a pediatric girl. Methods: Retrospective review of the ultrasound and magnetic resonance angiography (MRA) images of a 14-year-old girl enjoying good past health and presenting with recurrent syncope within three months was done. Results: Greyscale ultrasound found diffusely and circumferentially thickened walls with smooth contour and moderately increased echogenicity along bilateral common carotid arteries. Doppler ultrasound found spectral broadening and color aliasing within the lumens of bilateral common carotid arteries. The ultrasound features are highly suggestive of Takayasu’s arteritis. Magnetic resonance angiography (MRA) confirmed the ultrasound findings and showed the disease process was confined with the major branches of the aortic arch. Conclusions: Takayasu’s arteritis is a rare vasculitis. The clinical presentation of Takayasu’s arteritis can be non-specific, especially in the pediatric patients. Ultrasound examination is useful as the initiation investigation of the carotid arteries. Characteristic long, smooth, circumferential arterial wall thickening of bilateral carotid arteries can suggest the diagnosis of Takayasu’s arteritis and should prompt further investigation, especially MRA to delineate the extent of the disease.

Volume 43, Number S1, 2017 Objectives: To evaluate the correlation between different site of intracranial vertebral artery(VA) stenosis and posterior circulation ischemia (PCI) sympto. Methods: 319 cases of patients with unilateral VA stenosis of intracranial lesions confirmed by color Doppler flow imaging (CDFI), CT angiography(CTA) and(or) digital subtraction angiography (DSA):according to the relationship between lesion and posterior inferior cerebellar artery (PICA):before PICA 55 cases and after PICA 264 cases; according to whether the symptoms of PCI and magnetic resonance (MRI) results in symptoms of 132 cases and 187 cases without symptoms. CDFI analysis and record hemodynamic parameters and spectrum shape; evaluated the correlation between different site of intracranial VA stenosis and PCI symptoms. Results: 1.The comparison of the ipsilateral VA and contralateral show that the peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index(RI), VA diameter (VAD) had significant difference (p,0.05); The ipsilateral VA intervertebral segment PSV, EDV and RI was significantly related to position of PICA (P,0.05), but not VAD(p.0.05); 2.when the ipsilateral VA before PICA, intervertebral segment showed ‘‘spectrum unimodal’’ and after PICA showed ‘‘highresistance’’.3.VA intracranial stenosis and the symptoms of PCI are associated with moderately dependent (dependence coefficient 50.404, p,0.05). Conclusions: CDFI is a noninvasive assessment of VA intracranial stenosis, and the symptoms of PCI in ipsilateral VA before PICA was more serious. All of that can provide reliable basis for clinical treatment and prognosis.

Methods: A transcranial Doppler ultrasound examination. Results: According to the data of Ultra Sonic Testing (in C- and PWmodes) 109 patients (at the age from 2 to 18) it was found that discirculation in the system of vertebral veins is linked with apparent extravasal effects on bloodstream in internal jugular vein (with vessel compression on the side of vasoconstriction registration) (r5+0.67), spasms of posterior cerebral artery (r5+0.63), coiling of internal carotid and vertebral artery (r5+0.20 +0.32). In case of discirculation in the system of internal jugular vein, the changes mentioned are interrelated with extravasal compression on the level of internal jugular vein surrounding soft tissues or compression in the bone canal (r5+0.76), anterior cerebral artery spasms, hyperperfusion of vertebral and posterior cerebral artery (p,0.05). Intracranial venous discirculation depends on the straightness of vertebral artery in the bone canal (r5+0.33), discirculation intensity on the level of vertebral vein (Vmax right r5+0.73, p.0.05).Vasoconstriction in the vein of Galen is accompanied by ipsilateral hypersthenia of vertebral, internal carotid and middle cerebral artery (reflectory changes), and is also interrelated with flexures, sigmoid coiling of internal carotid artery.The link of ‘‘headache syndrome’’ with accelerated venous blood flow along the veins of Galen turned out to be quite low (r5+0,22). Conclusions: Main causes of children’s vasoconstriction are either congenital pathology of cervical spine (with arcuation and tortuosity of bone canal), or ‘‘birth injuries with pseudo-luxation of cervical vertebrae’’.
