Carotid pseudoaneurysm is a statistically low probability pathology, but when it occurs can even cause the patient's death, especially due to its complications (rupture, thrombosis and/or embolization). The main iatrogenic, percutaneous catheterization for placement of central line in neck vessels. We present through clinical case importance treatment guided by echo-Doppler.

We report on the initial results on a 5-plane CMUT array built on a single silicon substrate for operator-independent carotid artery screening. The array is used for color flow Doppler detection of peak blood velocity (PBV), which is correlated with carotid stenosis. Asymmetric acoustic lenses provide fixed angle off-axis beam steering for color flow Doppler. In the proposed system, first, five...

There is a large clinical requirement for novel vascular grafts; however, the development of novel vascular grafts has not been extremely successful to date. The most successful method for the continuous evaluation of vascular grafts in vivo remains unclear. Therefore, an optimal successive, non-invasive imaging modality is necessary for the study of vascular transplantation. In the present stu...

BACKGROUND AND PURPOSE Limited data exist on the frequency and outcome of carotid artery disease in Pakistan. Such information would help guide the usefulness of screening for the condition in this low-middle income health care setting. METHODS A prospective, descriptive study was conducted among 3 large teaching hospitals in Karachi, Pakistan. Patients referred for carotid Doppler ultrasound...

One hundred neurologically asymptomatic male subjects (aged 50-69 years), randomly selected through population registers, were screened for atherosclerotic lesions of the cervical carotid arteries, using a high resolution multi-gate pulsed Doppler system. In 93 subjects serum was assayed for total and HDL cholesterol. Besides, cuff arterial blood pressure measurements were made. Twenty-three of...

Ultrasound (US) is one of the most important diagnostic tools available for the detection and evaluation of carotid stenosis. The case of a 70-year-old woman with recurrent right-sided amaurosis fugax presented here highlights the way in which tissue Doppler imaging (TDI) and contrast-enhanced US (CEUS) may aid in the diagnosis of carotid plaque vulnerability. Furthermore, the novel inverse fly...

BACKGROUND AND PURPOSE Accurate carotid Doppler examination is an important issue in the light of large endarterectomy trials, but recommended cutoff values for detection of >70% stenosis vary widely. Standardization of diagnostic criteria should consider patient variation and instrument variability. METHODS We prospectively analyzed various Doppler parameters in 44 patients undergoing caroti...

Blood flow pattern and morphological changes within the extracranial carotid system were studied in M. fascicularis before, immediately after, and at various intervals (4 hours, 4 days, 10 days, and 4 weeks) after the introduction of systemic hypertension by surgical coarctation of the thoracic aorta. Intra-arterial hemodynamics were assessed by means of both continuous-wave Doppler signal spec...

BACKGROUND The hyperperfusion syndrome is a recognized complication of carotid endarterectomy. Reports of cerebral hyperperfusion injury following internal carotid artery (ICA) angioplasty are few, and this complication has never been reported following internal carotid stenting. CASE DESCRIPTION A 68-year-old normotensive man was referred to our hospital for assessment 5 months after experie...
