Bilateral Traumatic Internal Carotid Artery Dissection after CrossFit Training.

Bilateral traumatic internal carotid artery (ICA) dissection after CrossFit training is an extremely rare and life-threatening condition associated with high risk of cerebral ischemia. Several imaging modalities are involved in its clinical evaluation and clinical decision-making. Anticoagulation and antiplatelet management, endovascular therapy, and open surgical intervention are the available options for ICA dissection treatment.

Correlation between venous pressure gradients and intravascular ultrasound in the diagnosis of iliac vein compression syndrome.

Objective: The objective of this study was to evaluate the correlation between venous pressure gradients (VPGs) and intravascular ultrasound (IVUS) for the diagnosis of caval-iliac venous obstructions in patients with advanced chronic venous insufficiency.

Methods: Fifty patients with advanced chronic venous insufficiency symptoms (Clinical, Etiology, Anatomy, and Pathophysiology class 3 to 6) were prospectively submitted to multiplanar venography (MV) with intravenous pressure measurements and IVUS. The patients' lower limbs were divided accordingly: group I, limbs with <50% obstruction on IVUS (n = 49); and group II, limbs with ≥50% obstruction on IVUS (n = 51).

Prospective, double-blind, randomized controlled trial comparing electrocoagulation and radiofrequency in the treatment of patients with great saphenous vein insufficiency and lower limb varicose veins.

Objective: Thermoablation has been replacing conventional surgery in the surgical treatment of great saphenous vein (GSV) reflux in patients with lower limb varicose veins; however, thermoablation is expensive. Intravenous electrocoagulation (EC) may, selectively and safely, cause necrosis of the GSV wall, but the clinical results have never been studied. The objective of this study was to compare EC and radiofrequency ablation (RFA) in the treatment of GSV insufficiency, considering efficacy, complications, and effect on quality of life.

Aortocaval fistulae are rare entities with a variety of etiologies and are very often associated with significant morbidity and mortality. It is believed that increased tension in the walls of large aneurysms can cause an inflammatory reaction resulting in adhesion to the adjacent vein and culminating in erosion of the adherent layers and fistula formation. Conventional surgical treatment has high mortality rates.

Hydrocortisone supresses inflammatory activity of metalloproteinase-8 in carotid plaque.

Objective: Matrix metalloproteinases are inflammatory biomarkers involved in carotid plaque instability. Our objective was to analyze the inflammatory activity of plasma and carotid plaque MMP-8 and MMP-9 after intravenous administration of hydrocortisone.

Methods: The study included 22 patients with stenosis ≥ 70% in the carotid artery (11 symptomatic and 11 asymptomatic) who underwent carotid endarterectomy.

Analysis of the acute systemic and tissue inflammatory response following carotid endarterectomy.

Background: We aimed to investigate the acute systemic and tissue inflammatory response associated with carotid endarterectomy (CEA) and analyze the association between serum and tissue biomarkers and histological features of carotid plaques between symptomatic and asymptomatic patients.

Methods: We studied 11 patients (6 symptomatic and 5 asymptomatic) with ≥70% internal carotid stenosis treated with CEA. Serum expression of interleukin (IL) 1β, IL-4, IL-6, IL-8, IL-10, metalloproteinase (MMP) 8, MMP-9, tumor necrosis factor-α (TNF-α), high-sensitive C-reactive protein (hs-CRP), and vascular endothelial growth factor (VEGF) were measured in the preoperative period and 1, 6 and 24 hours after CEA.

Experimental determination of the best time and duration for endovenous great saphenous vein electrocoagulation.

Objective: Endovenous electrocoagulation provokes immediate selective venous wall necrosis. In this study, we aim to determine the best power and time of electrocoagulation necessary to cause intima and media but not adventitia layer damage in great saphenous vein (GSV) insufficiency treatment.

Methods: We studied 100 varicose GSV fragments submitted to endovenous electrocoagulation.

Peripheral arterial occlusive disease and ankle-brachial index in patients who had coronary angiography.

Objective: To evaluate the prevalence of peripheral arterial disease (PAD) in patients with coronary arterial disease. To evaluate the relation between ankle-brachial index (ABI) and coronary arterial disease, and its correlation with cardiovascular risk factors.

Method: ABI investigated with Doppler ultrasonic device.
