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...
OBJECTIVE To compare duplex ultrasound and computed tomography (CT) angiography in terms of their performance in detecting endoleaks, as well as in determining the diameter of the aneurysm sac, in the postoperative follow-up of endovascular abdominal aortic aneurysm repair. MATERIALS AND METHODS This was a prospective study involving 30 patients who had undergone endovascular repair of infrar...
Duplex ultrasound is widely used to detect vascular dysfunction after kidney transplantation. We describe musical murmurs found in renal allografts. A 29-year-old man with an increase in serum creatinine 1 month after cadaveric kidney transplantation was referred for duplex ultrasound to exclude perfusion dysfunction. Renal arterial and venous circulation was normal. However, during Doppler spe...
BACKGROUND AND PURPOSE Real-time compound ultrasound imaging is a new technique for improving the image quality of B-mode scanning. We investigated the value of this method for the characterization of atherosclerotic plaques in the internal carotid artery. METHODS Thirty-two patients (22 men, 10 women; mean age, 75 years) with plaques of the internal carotid artery as identified by high-resol...
Backgrounds: There are controversies among surgeons about prophylaxis of deep vein thrombosis (DVT) in laparoscopic cholecystectomy. The aim of this study was the assessment of patients’ condition after laparoscopic cholecystectomy without any prophylactic measure. Methods: 100 cases of laparoscopic cholecystectomy without DVT prophylaxis were followed by duplex scanning in the first postopera...
INTRODUCTION Selection of the optimal anastomosis site is essential for obtaining good results from distal bypass. Herein, a unique, precise technique that uses pre-operative duplex scanning for selecting this site is presented. TECHNICAL SUMMARY Before distal bypass surgery, duplex scanning is performed to assess patency and flow. Use of the venous preset mode and controlling the slant funct...
Accurate diagnosis of deep venous thrombosis (DVT) and pulmonary embolism (PE) is required because treatment can be life-saving, while inappropriate anticoagulation exposes the mother and fetus to haemorrhage and other hazards. Clinicians must be aware of which patients are at risk because DVT is frequently asymptomatic. Clinical diagnosis is unreliable for DVT and PE so objective tests are req...
Introduction Hypertension affects up to 65 million adults in the United States. A small subset of these patients have renovascular hypertension due to obstruction of the renal arteries. Fortunately, this type of hypertension can be corrected with treatment of the offending renal artery stenosis. Many hypertensive patients are referred for duplex ultrasound to screen for the presence of renal ar...
OBJECTIVE We present a case of recurrent bilateral lower extremity venous stasis ulcers in association with a superficial venous aneurysm at the right saphenofemoral junction that was misdiagnosed on preoperative duplex scanning. METHODS A 53-year-old female presented to our clinic with 6-year history of bilateral lower extremity venous stasis ulcers. Her past medical history was significant ...
