BACKGROUND: The Mediterranean dietary pattern has been associated with a decreased risk of many degenerative diseases and cognitive function in particular; however, relevant information from Mediterranean regions, where the prototype Mediterranean diet is typically adhered to, have been very limited. Additionally, predefined Mediterranean diet (MeDi) scores with use of a priori cut-offs have been used very rarely, limiting comparisons between different populations and thus external validity of the associations...

Ovarian vein thrombosis (OVT) is a rare medical disorder most often diagnosed in the peripartum period and maybe associated with other risk factors for thrombosis. Rarely, OVT is considered idiopathic. It occurs in the right ovarian vein alone in two-thirds of patients. In this report, we present a case of idiopathic and bilateral OVT in a 35-year-old woman who presented with 2-day history of left flank pain. Duplex ultrasound imaging and computed tomography confirmed the diagnosis. Oral anticoagulation achieved a favorable outcome...

BACKGROUND: Contemporary texts frequently present the venous system of the lower limb as a prime example of bilateral symmetry. However, overt bilateral asymmetry may be noted. This study was designed to examine and to quantify the level of symmetry in the lower extremity veins. METHODS: This prospective cohort study evaluated major anatomic differences between right and left lower extremity veins in adult patients. Two hundred patients presenting with signs and symptoms of chronic venous disease (CVD; class 2-6) and venous reflux on duplex ultrasound were examined...

BACKGROUND: The severity of pulmonary embolism (PE) after isolated calf deep vein thrombosis (C-DVT) is controversial, which leads to inconsistent clinical decision making when treating C-DVT. This systematic review assessed PE frequency and severity in patients with C-DVT. METHODS: Database searches were completed using MEDLINE and Scopus along with cross-referencing. Two independent reviewers used using rigorous inclusion and exclusion criteria to screen the papers...

OBJECTIVE: This prospective study was designed to determine the great saphenous vein (GSV) wall thickness in age-related and venous reflux-associated remodeling. METHODS: GSV wall thickness was measured in the thigh and calf using a duplex ultrasound 17-MHz transducer. Interobserver and intraobserver variability studies were performed. Two healthy control groups, each with 10 individuals (20 limbs), were selected on the basis of age. Group 1 had a mean age of 21 years, and group 2 had a mean age of 64 years...

235 Background: The Contemporary Oncology Team was the first practice in Greece to participate in the Quality in Oncology Practice Initiative (QOPI). As a result, several corrective measures were designed and implemented to improve the quality of the services provided to patients. METHODS: The plan-do-check-act approach was used to implement changes, primarily in the follow up form, over a period of 18 months. Several improvement opportunities were identified. 1.) A numerical scale for pain intensity quantification became a required field...

Pelvic congestion syndrome is one of the many causes of chronic pelvic pain and is often diagnosed based on exclusion of other pathologies. Over the past decades, pelvic congestion syndrome was recognized to be a more common cause of chronic pelvic pain. Multiple diagnostic modalities including pelvic duplex ultrasonography, transvaginal ultrasonography, computed tomography, and magnetic resonance were studied. In the current literature, selective ovarian venography, an invasive imaging approach, is believed to be the gold standard for diagnosing pelvic congestion syndrome...

BACKGROUND: The purpose of this study was to evaluate the risks of bleeding, deep venous thrombosis (DVT), endovenous heat induced thrombosis (EHIT) and failure of ablation on patients who undergo ablation while on oral anticoagulation. METHODS: We compared 378 (3.4%) out of 11252 patients (group A) who had undergone 724 endovenous ablation of the saphenous veins from January 1, 2011 to September 30, 2014 while on oral anticoagulation to a randomly selected 375 patients (group B) who underwent 641endovenous ablation in the same time period but were not on anticoagulation...

BACKGROUND: The impact of early physician follow-up on out-of-hospital outcomes after cerebral aneurysm treatment has not been studied previously. We investigated the association of early physician follow-up (within 30 days of discharge) with mortality and readmissions for elderly patients undergoing treatment for cerebral aneurysms. METHODS: We performed a cohort study of 100% of Medicare fee-for-service claims data for elderly patients who underwent treatment for cerebral aneurysms from 2007 to 2012...

Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms results in redirection of blood through the deployed endograft (EG). Even though EVAR is clinically effective, the absolute flow restoration is not warranted. Our purpose was to compare the physiological with the post-EVAR infrarenal flow conditions. We developed patient-specific models based on computed tomography data of five healthy volunteers and ten patients treated with the Endurant(®) stent-graft system. Wall shear stress (WSS), helicity, pressure and velocity fields were calculated using computational fluid dynamics...

True aneurysms of the tibioperoneal trunk are rare. Given the scarcity of reports, the clinical presentation and treatment is not well defined. This is a case report of a 50-year-old male patient presenting with severe lower extremity swelling and compartment syndrome with neurological compromise secondary to a tibioperoneal trunk aneurysm. He was also noted to have discrete ipsilateral popliteal and dorsalis pedis artery aneurysms. Given the location and size of the aneurysm, the severe leg swelling, and venous hypertension, aneurysmorrhaphy or aneurysm sac excision with arterial reconstruction was prohibitively dangerous...

OBJECTIVE: Perforator vein aneurysms (PVAs) of the lower extremity have not been defined or reported. This study reports the clinical presentation of patients, the PVA characteristics, and the clinical outcome of their management. METHODS: Patients with signs and symptoms of chronic venous disease who had a PVA were included. Diagnosis of a PVA was made with duplex ultrasound. Normal perforator veins have a diameter of <3 mm. A PVA was defined as a diameter dilation of >9 mm, and it was always found below the deep fascia...
