Acute dissection of thoracic aorta carries a risk of renal ischemia followed by the development of a kidney failure. The optimal surgical and nonsurgical management of these patients, timing of intervention, and the factors predicting renal recovery are not well delineated and remain controversial. We present a case of acute type B thoracic aortic dissection with left kidney ischemia. Evaluation of renal function was performed by the means of internationally accepted Risk, Injury, Failure, Loss of kidney function, End stage kidney disease and Acute Kidney Injury Network classifications for acute kidney injury, renal duplex sonography, and intravascular ultrasound that demonstrated left renal artery dissection with a flap completely compressing the true lumen...

Chronic venous disease is a common disorder associated with a variety of symptoms in later disease stages but also with complications such as venous leg ulcer. This, in turn, has substantial socioeconomic effects and significantly impacts patients' quality of life. While there are a number of diagnostic procedures available, color-flow duplex ultrasound has become the gold standard. As regards therapeutic options, major advances have been made in recent decades. Today, there are alternatives to saphenofemoral ligation and stripping of the great saphenous vein, including endovenous thermal ablation techniques...

BACKGROUND: Pink pulseless hand syndrome is a rare condition of vascular injury due to distal humerus fracture. It is characterized by radial and ulnar pulselessness in a complex of good hand perfusion which can remain pink and warm. The management and treatment of this condition is still very debated. METHODS: We report four cases of arm traumas which occurred in pediatric patients. In all cases, after the fixation of the fracture by the orthopedic surgeon, the clinical evaluation and duplex ultrasound demonstrated the so called "pink pulseless hand syndrome"...

INTRODUCTION: Carotid plaques with a high degree of calcification are usually considered at low embolic risk. However, since a precise evaluation of the extent of calcification is not possible preoperatively through duplex ultrasound and postoperatively by conventional histological examination due to the de-calcification process, the relationship between the amount of calcium involvement and plaque vulnerability has not been evaluated yet. This study aims to correlate the extent of carotid plaque calcification with clinical, radiological and histological complications...

Colour duplex sonography (CDS) of temporal arteries and large vessels is an emerging diagnostic tool for GCA. CDS can detect wall oedema, known as a halo, throughout the length of the vessel and shows higher sensitivity compared with biopsy. Specificity reaches 100% in case of bilateral halos. A positive compression sign has been demonstrated to be a robust marker with excellent inter-observer agreement. The assessment of other large vessels, particularly the axillary arteries, is recognized to further increase the sensitivity and to reliably represent extra-cranial involvement in other areas...

Lower extremities varicose veins are among the most frequent diseases in the general population. They can cause complaints with a deterioration of the quality of life and are associated with potentially threatening clinical conditions such as chronic venous ulceration, haemorrhage from ruptured varicose veins, and venous thromboembolism. An accurate diagnostic work-up is crucial to confirm the presence and the extension of the venous problem, in order to obtain an optimal management of the condition. In the past years, great efforts have been made to reach an international consensus on the terminology, the symptomatology, the classification, and the duplex ultrasound examination of lower extremities varicose veins...

Patients with symptomatic carotid artery disease should be managed by a multidisciplinary team including neurologists, vascular surgeons and interventionalists. Duplex ultrasound is the most widely used diagnostic modality to assess carotid disease, followed by additional imaging tests (CT- or MR-angiography) to confirm the severity of the stenosis, detect brain lesions, and assess intracranial circulation as well as the supra-aortic anatomy. Although overall randomized trial results favored (CEA) over carotid artery stenting (CAS) in symptomatic patients, this was likely related to the insufficient expertise of the endovascular specialists in several of the trials...

INTRODUCTION: The effectiveness of renal sympathetic denervation (RDN) as a treatment for therapy-resistant hypertension has been doubted as the Simplicity-HTN-3 trial was unable to show any treatment benefit over sham procedure. This might partly be explained by a high procedural variability in treatment with radiofrequency-based catheters. Recently, newer systems for RDN, like ultrasound-based devices, have been introduced into practice. To date however, data on their effectiveness for the treatment of resistant hypertension are scarce...

BACKGROUND: In patients with acute ilio-femoral deep vein thrombosis (IFDVT), catheter-directed thrombolysis (CDT) aims to prevent the post-thrombotic syndrome (PTS). Adding intravascular high-frequency, low-power ultrasound energy to CDT does not seem to improve the immediate thrombolysis results but its impact on clinical outcomes at 12 months is not known. PATIENTS/METHODS: In this randomized-controlled trial, 48 patients (mean age 50±21 years, 52% women) with acute IFDVT were randomized to conventional CDT (n=24) or ultrasound-assisted CDT (USAT; n=24)...

OBJECTIVE: Although duplex ultrasound (DUS) imaging is the current gold standard in the diagnosis of femoropopliteal deep venous thrombosis, it is not an optimal diagnostic modality to diagnose iliocaval occlusion. Screening for iliocaval occlusion thus remains a challenge for clinicians because of the lack of a reliable noninvasive technique. This challenge results in most patients undergoing computed tomography venography or magnetic resonance venography or invasive venography and intravascular ultrasound imaging...
