Purpose—To assess the impact of a structured duplex ultrasound hemodialysis access surveillance program on the frequency of diagnostic fistulograms and endovascular interventions.Methods—A structured ultrasound hemodialysis access surveillance program was implemented at our institution on March...
Introduction—High resistive internal carotid artery (ICA) waveforms (high peak systolic velocity >250 cm/sec with low end-diastolic velocity (EDV) <125 cm/sec, having an external carotid artery waveform appearance) are uncommon and present a diagnostic challenge for intervention. Most ICA...
Objective—Current imaging techniques are limited in their ability to quantify thrombus burden, progression, or resolution in patients with acute deep-vein thrombosis (DVT). These assessments are critical measures of therapeutic success when thrombolytic or thrombectomy treatment protocols are...
Objective—To describe a case of axillary artery embolus detected by emergency physician- performed bedside ultrasound.Case Report—A patient presented with a possible stroke but was diagnosed correctly with acute axillary artery embolus. The axillary artery embolus was detected by the emergency...
Introduction—Although popliteal vein aneurysms are the most common of all venous aneurysms, they are exceedingly rare. In fact, there have only been approximately 150 reported cases to present. We present a case of a popliteal vein aneurysm found in a patient with right lower-extremity...
Venous duplex scanning can be divided into two different subcategories: (1) scanning to diagnose thrombus and (2) scanning to diagnose incompetence. Venous incompetence testing is used to assess the physiology of the superficial and deep venous systems, making it a much more complex and...
