BACKGROUND The aim of this study is to describe point-of-care ultrasound and Color flow Duplex Doppler characteristics of penetrating and blunt trauma-related vascular injuries of the limbs and neck. METHODS Penetrating and blunt trauma-related vascular injuries such as vein disruption, intimal flap, deep vein thrombosis, arterial dissection, pseudoaneurysm, and arteriovenous fistulae are dis...

Aneurism of the vein of Galen is a complex arteriovenous malformation which is of multiply communications between of the vein of Galen and the cerebral arteries. It represents less than 1% of the cerebral arteriovenous malformations. Few cases using three-dimensional (3D) power and color Doppler ultrasound have been reported in the literature. We present a case of an aneurysm of the vein of Gal...

PURPOSE To determine whether color Doppler sonography can be a sensitive alternative to screening arteriography for identifying arterial injury in patients with penetrating traumatic neck injuries. METHODS Fifty-two patients admitted to our trauma center with penetrating neck injuries (gunshot wounds and lacerations) were examined prospectively with color Doppler sonography, and findings were...

Renal arteriovenous fistula (AVF) is an uncommon clinical entity, which can be congenital, acquired, or idiopathic. Diagnosis is aided by radiological studies, with digital subtraction angiography as a gold standard. However, Doppler ultrasound with color Doppler interrogation and computed tomography (CT) angiography are alternative imaging techniques that are noninvasive and can be used for pa...

Background and aims. Although salivary gland tumors are not very common, early diagnosis and treatment is crucial because of their proximity to vital organs, and therefore, determining the efficacy of new imaging procedures becomes important. This study aimed to evaluate the efficacy of magnetic resonance imaging (MRI) and color doppler ultrasonography parameters in the diagnosis and differenti...

BACKGROUND The purpose of this study was to evaluate the correlation among intratumoral blood flow as assessed by color Doppler ultrasonography, clinicopathological findings and the Nottingham Prognostic Index (NPI). METHODS Twenty-seven patients with breast cancer were examined. All patients received surgical treatment. Color Doppler ultrasonography was performed prior to surgery to detect a...

OBJECTIVE The purpose of this study was to describe and evaluate the sonographic and color Doppler features of tumorlike biliary and venous changes in patients with cavernous transformation of the portal vein (CTPV). METHODS The sonographic studies of 24 patients with CTPV were reviewed. Sonographic evaluation of the biliary system included measurement of intrahepatic and extrahepatic biliary...

OBJECTIVE This study aimed to investigate the influence of injection rates of calibrating standard solution on monitoring pulse indicator continuous cardiac output (PICCO, made in Germany), and thereby to provide significant references for clinical practice. METHODS A total of 108 critical patients in stroke intensive care unit were identified. All these participants received transesophageal ...

BACKGROUND Abernethy malformation is a rare congenital vascular abnormality in which the portal vein bypasses the liver and drains directly into the inferior vena cava. Diagnosis is complex and requires good quality imaging methods to identify details in systemic and portal circulation in order to establish diagnostic confirmation and treatment strategy. In this study we highlight the significa...

We performed color Doppler flow mapping in 15 patients, 1 week to 17 years old (mean 42 months), with coarctation of the aorta that was confirmed subsequently by angiography and/or surgery. Twelve patients had native coarctation and three had mild recoarctation after surgical repair. Color Doppler flow maps were analyzed with a digital analysis package and a Sony computer system. The diameter i...
