BACKGROUND: Although unprovoked superficial venous thrombosis (SVT) has traditionally been considered a local, benign disorder, recent studies demonstrate that patients with SVT are at significant risk for deep venous thrombosis, pulmonary embolism, and other venous thromboembolism (VTE) events. Nevertheless, clinical management remains widely inconsistent. Moreover, patients with multiple, unprovoked SVTs of noncommunicating anatomic sites have not been previously described, and they may be at even increased risk for adverse outcomes...

Objective: The purpose of this study was to evaluate potential factors affecting patient non-compliance after endovascular aneurysm repair. Method: We performed a retrospective review of patients undergoing elective or emergency endovascular repair for thoracic, abdominal aorta, or iliac artery aneurysm at a single institution from November 2007 to March 2014. Compliance to follow-up at 1, 6, and 12 months was assessed. Factors evaluated included patient demographics, size of aneurysm, distance between the patient's residence and outpatient clinic, urgency of surgery, and time of year in which the follow-up visits were scheduled...

REVIEW
Raudel Garcia, Nicos Labropoulos
Venous diseases are highly prevalent, mostly caused by valve incompetence and/or obstruction of the vein lumen. Signs and symptoms are diverse and unspecific. Careful clinical assessment and imaging interpretation are crucial to diagnosis. Duplex ultrasound is the first choice and often the gold standard imaging technique for this purpose, providing information on the anatomy and function of the veins. This article describes the sonographic anatomic and hemodynamic criteria used for the diagnosis of venous reflux, venous obstruction, and the most frequent complications after interventions in the superficial, perforating, and deep venous systems...

BACKGROUND: Atherosclerosis usually develops at geometrically susceptible areas, despite the impact of systemic risk factors on the entire vascular system. The aim of our study was to investigate whether carotid bifurcation geometry as assessed by ultrasound is associated with early carotid atherosclerosis, regardless of the presence of known atherosclerotic risk factors. MATERIAL AND METHODS: A nonrandomized prospective study was undertaken, including subjects of both genders, aged 50-60 years, without known cardiovascular family history, and symptoms and/or signs of cardiovascular disease...

#7
Edvard Skripochnik, Nicos Labropoulos, Shang A Loh
We present the case of delayed migration of a thrombosed aortic endograft within a thrombosed aneurysm sac that expanded and ruptured. Dilation of the aortic neck likely led to endograft migration and exposure of the occluded endograft and aneurysm sac to systemic pressure. Although no endoleak was identified, a key finding on ultrasound showed mobility of the sac thrombus. This may be an indicator of flow within the sac that may predict potential for rupture. Despite thrombosis of the aortic sac and endograft, the risk of rupture still lingers, and thus continued surveillance of occluded endografts may be prudent...

Intravascular leiomyomatosis (IVL) is a benign smooth muscle tumor that evolves from the pelvic veins and can spread to the central veins and heart. Cardiac involvement is the most commonly reported presentation. Initial diagnosis is difficult, and IVL is commonly misdiagnosed as thrombus or atrial myxoma. Appropriate imaging and a high clinical suspicion are required for accurate diagnosis. We report a rare case of IVL in the external iliac vein that recurred 4 years after hysterectomy. Only four cases have been reported in the literature to involve the external iliac vein as it has no direct connection to pelvic venous drainage...

BACKGROUND: The physical properties of a venous thrombus are derived from molecular characteristics, including fibrin polymer diameter, density, branching, and cross-linking. Dense thrombi with thin, highly branched fibrin fibres and small pores in the meshwork have been observed to be more rigid, less permeable, and more resistant to lysis. The three dimensional fibrin meshwork acts as the main structure to entrap and capture erythrocytes, platelets and plasma components. Attached factors become integrated into the developing thrombus, co-localise with fibrin deposition and act in either a pro- or anticoagulant capacity...

OBJECTIVE: The objective of this study was to delineate the specific types of waveforms that exist in type II endoleaks (T2ELs) and their effect on aneurysm sac size. METHODS: Patients who underwent an endovascular aneurysm repair and were diagnosed with a T2EL were included in the study. The flow velocity characteristics of the T2ELs were evaluated in detail with duplex ultrasound. Four different flow patterns were identified: high resistance, low flow; low resistance, low flow; low resistance, high flow; and to-fro flow...

OBJECTIVE: Previous studies of men suggested that patients with varicocele may be leaner than the normal population. No such work exists in women with pelvic congestion syndrome (PCS). This study evaluated the correlation between body mass index (BMI) and PCS. METHODS: A case-control study at a single institution was performed of women who had the objective diagnosis of PCS. Data were prospectively collected for 100 consecutive patients with PCS. BMI was calculated for every patient and categorized into normal weight (BMI <25), overweight (BMI 25-29...

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...
