conclusion for more precise prediction of successful aavf maturation after spta, short-term follow-up doppler ultrasonography (< 2 weeks) was useful. if the asr was < 0.7 or if residual stenosis was ≥ 30%, immediate repeat spta is recommended. results the technical and clinical success rates were both 94.9% (56/59); the mean asr was 0.84. an asr of ≥ 0.7 and no significant residual stenosis (< ...

background: stroke is a multifactorial disorder, the most common cause being arterial occlusion. transcranial doppler ultrasonography (tcd) is a common non-invasive method available for assessment the arterial blood flow of the brain. objective: assessment the hemodynamic parameters of cerebral arteries, using tcd device in patients suffering ischemic stroke. materials and methods: this descrip...

A 65-year-old woman with no medical history of interest was attended in our outpatient Gastrointestinal Clinic because of a persistent pain in the right upper quadrant of the abdomen for several days. Physical examination was normal. Hemogram, coagulation tests and blood biochemistry –including transaminases and alkaline phosphatase– did not show meaningful alterations. An abdominal ultrasound ...

Transcranial Doppler ultrasonography has been used to detect microemboli in the middle cerebral artery during orthopedic surgery. We conducted a comprehensive systematic literature review of transcranial Doppler ultrasonography in orthopedic surgery to evaluate its status in this setting. Fourteen studies were selected for qualitative analysis. The highest number of patients studied was 45; emb...

In this article, functional structures on the ovaries of bitches before and after ovulation are evaluated with Doppler ultrasonography information concerning interpretations findings transferred. effect is first step imaging. This shift in frequency transmitted ultrasound. Spectral and/or color easiest most important diagnostic technique assessing ovarian hemodynamic. The angle used by instrume...

Differential diagnosis of acute scrotum especially with acute epididymis and testicular torsion should be made promptly, as testicular torsion is a true surgical emergency of the highest order. In this manuscript, two demonstrative cases introducing with acute scrotum and diagnosed with scintigraphy and color Doppler ultrasonography were presented to recall the knowledge.

Carotid duplex ultrasonography is a noninvasive technique for hemodynamically significant stenosis detection and cardiovascular risk estimation. Anatomic information of carotid arteries is provided by B-mode scanning. Hemodynamic features are displayed color-flow and pulsed Doppler imaging. Examination technique, normal carotid anatomy and flow pattern, and potential limitations are presented.

OBJECTIVES Arteriogenic erectile dysfunction (ED) is a target organ disease of atherosclerosis, and therefore might be a predictor of systemic atherosclerosis. Being systemic, it might be possible to evaluate the extent of atherosclerosis from retinal vascular findings. We investigated the possible correlation between penile cavernosal artery blood flow and retinal vascular findings in patients...

Paragangliomas rarely originate from the pancreas and they are characterized on imaging studies as well-marginated, hypervascular masses with cystic areas. We herein report on a case report of pancreatic paraganglioma in a 57-year-old woman, which was confirmed on pathology. Color Doppler ultrasonography and dynamic CT demonstrated a well-demarcated, extremely hypervascular mass with prominent ...
