Background: There has been a large discussion in literature regarding the proper management of asymptomatic patients with significant carotid artery stenosis. This study aims to identify potential risk factors associated with high-risk carotid plaques.
Methods: This is a retrospective study based on a prospective database.
Objectives: to evaluate direct oral anticoagulants (DOACs) in patients with hereditary thrombophilia and deep venous thrombosis (DVT).
Methods: This is a retrospective observational study.
Results: In total, 45 patients were treated between 01/2012 and 12/2022 (mean follow-up: 1.

Carotid atherosclerotic plaque growth leads to the progressive luminal stenosis of the vessel, which may erode or rupture causing thromboembolism and cerebral infarction, manifested as stroke. Carotid atherosclerosis is considered the major cause of ischemic stroke in Europe and thus new imaging-based computational tools that can improve risk stratification and management of carotid artery disease patients are needed. In this work, we present a new computational approach for modeling atherosclerotic plaque progression in real patient-carotid lesions, with moderate to severe degree of stenosis (>50%).

We sought to determine whether the presence of PD in patients with severe carotid disease was associated with morphological features consistent with carotid plaque instability.
Methods: A total of 52 dentate patients hospitalized for carotid endarterectomy (CEA) had standardized assessments of their periodontal status, including measurements of probing pocket depth (PPD), clinical attachment level (CAL) and bleeding on probing (BoP).
Valid characterization of carotid atherosclerosis (CA) is a crucial public health issue, which would limit the major risk held by CA for both patient safety and state economies. CA is typically diagnosed and assessed using duplex ultrasonography (US). Elastrography Imaging (EI) is a promising US technique for quantifying tissue elasticity (ES).

The committees created working groups on color Doppler ultrasound (US), magnetic resonance (MR) imaging, catheter venography (CV), and intravascular US. Each group organized a workshop focused on its assigned imaging modality.

Background: Studies of human carotid artery samples showed increased heat production. MR allows in vivo noninvasive measurement of internal temperature of tissues.
We assessed the association between the haptoglobin (Hp) genotype and 2 common indicators of atherosclerotic plaque instability: macrophage infiltration and the smooth muscle cell (SMC) content. A total of 70 consecutive patients who underwent carotid endarterectomy were included in the study. For immunohistochemical study the anti-CD68 and anti-a-actin antibodies were used on adjacent serial sections; 36 plaques from patients with the Hp 1-1 or 2-1 genotype and 34 plaques from patients with the Hp 2-2 genotype were analyzed.

In the present study the value of this method for the characterization of atherosclerotic plaques in the internal carotid artery was investigated.
Methods: Two hundred and twenty two patients (161 men, 61 women; mean age 73 years) referred for carotid ultrasound evaluation were included in the study.
Objective: Evaluate the performance and safety of the FiberNet Embolic Protection System during carotid artery intervention.
Background: Carotid Angioplasty and Stenting (CAS) can be proposed to treat the majority of carotid stenoses. Brain embolization takes place and routine use of Embolic Protection Devices (EPD) is warranted.
Spontaneous internal carotid recanalization has been infrequently observed, and when it has been reported, it has most commonly occurred early after a stroke. We report a case of a patient with late spontaneous recanalization of the internal carotid artery (ICA) that occurred within 6 months to 1 year after the initial diagnosis of occlusion during the course of a stroke. This event allowed the patient to undergo a successful surgical intervention.

Acquired systemic arteriovenous (A-V) fistulas following spinal surgery (laminectomy) are a less recognized cause of secondary pulmonary hypertension. We describe a patient who presented with symptoms and clinical evidence of pulmonary hypertension and underwent endovascular correction of an acquired A-V fistula, which led to improvement according to clinical and noninvasive hemodynamic criteria.

Objectives: To study the development and progression in time of deep venous valve incompetence with Duplex ultrasonography in combination with distal cuff deflation in patients with a history of deep venous thrombosis (DVT) and to evaluate symptoms of chronic venous insufficiency (CVI).
Design: Prospective cohort study.
Materials And Methods: In a long term follow-up study the deep venous system of 24 patients (7 men, 17 women, mean age 51 years) of an initial group of 27 with phlebographically documented deep venous thrombosis were examined with Duplex scanning at two intervals (mean 34 and 86 months) after DVT.
During a 5 year period we have identified leiomyomas of the small intestine in six patients using enteroclysis. Gastrointestinal bleeding were the presenting symptoms in five and partial small bowel obstruction in one. The time interval between the onset of symptoms and radiological diagnosis ranged between 3 months and 5 years.
