BACKGROUND: The standard of care for treatment of lymphedema is manual lymphatic drainage and compression therapy, which is time intensive and requires a life-long commitment. Autologous lymph node transfer is a microsurgical treatment in which a vascularized lymph node flap is harvested with its blood supply and transferred to the lymphedematous region to assist with lymph fluid clearance. An ideal donor lymph node site minimizes the risk of iatrogenic lymphedema and other donor site morbidity...

Non-atherosclerotic myocardial infarction (MI) is an important but often misdiagnosed cause of acute MI. Furthermore, non-atherosclerotic MI with concomitant acute stroke and pulmonary embolism due to in-transit thrombus across a patent foramen ovale (PFO) is a rare but potentially fatal combination (1-3). Early detection of this clinical entity can facilitate delivery of targeted therapies and avoid poor outcome (1, 2). Here, we describe a 68-year-old female with hypertension, tobacco abuse, and chronic obstructive pulmonary disease presenting with facial droop, right arm weakness and aphasia...

BACKGROUND: Optimal antithrombotic therapy after lower limb infra-inguinal revascularization remains a controversial topic. The use of anticoagulants, alone or in combination with antiplatelet drugs, can potentially improve patency rate and limb salvage, particularly in patients with risk factors for early thrombosis. Bleeding is the main complication of long term anticoagulant use. New oral anticoagulants can represent an attractive alternative to the standard vitamin K-antagonists. OBJECTIVE: evaluate the effectovemess (bypass occlusion and major amputation) and safety (major bleeding and all-cause mortality) of rivaroxaban compared to acenocoumarol after infra-inguinal lower limb surgical revascularization...

Peripheral arterial occlusive disease is a chronic pathology affecting at least 8-12 million people in the USA, typically treated with a vein graft bypass or through the deployment of a stent in order to restore the physiological circulation. Failure of peripheral endovascular interventions occurs at the intersection of vascular biology, biomechanics, and clinical decision making. It is our hypothesis that the majority of endovascular treatment approaches share the same driving mechanisms and that a deep understanding of the adaptation process is pivotal in order to improve the current outcome of the procedure...

Fetal intra-abdominal umbilical vein varix (FIUVV) is a rare pathology and suggests an enlargement of the umbilical vein. Prenatal diagnosis is done through meticulous ultrasound imaging. Management variables are the diameter of varix, presence or absence of turbulent flow, and fetal anomalies. Color and power Doppler ultrasound helps in diagnosis and follow-up and has a critical role in decision-making for intervention. Clinical guidelines for management are not clear. The adverse fetal outcome is usually associated with multiple malformations, turbulent flow, and thrombotic varix...

Optical coherence angiography (OCTA) is a noninvasive technique that has been introduced in recent years to detect ophthalmological pathology. The growing usage of OCTA to detect retinal abnormalities can be attributed to its advantages over the reference-standard fluorescein angiography (FA), although both of these techniques can be used in association. OCTA's advantages include its dye independency, its ability to produce depth-resolved images of retinal and choroidal vessels that yield images of different vascular layers of the retina, and the better delineation of the foveal avascular zone...

BACKGROUND: The duodenum and the left renal vein occupy the vascular angle made by the superior mesenteric artery and the aorta. When the angle becomes too acute, compression of either structure can occur. Each type of compression is associated with specific clinical symptoms that constitute a rare disorder. If clinical symptoms are mild, conservative treatment is implemented. However, surgery is often the only solution that can improve quality of life and/or avoid life-threatening complications...

Baicalin is one of the main active ingredients of choleretic traditional Chinese medicine drug Radix Scutellariae. The aim of this study was to explore the pharmacokinetic characteristics of baicalin in rats with 17α-ethynylestradiol (EE)-induced intrahepatic cholestasis (IC) based on its choleretic effects. Firstly, rats were subcutaneously injected with EE solution (5 mg/kg, 0.25 mL/100 g) for 5 consecutive days to construct an IC model. Then the bile excretion rate, serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and total bile acid (TBA) and pathological changes of the liver were detected...

We report a case of left renal angiomyolipoma extending into the renal vein. A 67-year-old woman showed a left renal tumor which was 6 cm in diameter and had density equal to fat tissue in computed tomography. We suspected liposarcoma and performed radical nephrectomy and resection of thrombus. The pathological diagnosis was angiomyolipoma with no malignancy. To our knowledge, renal angiomyolipoma with tumor thrombus has been reported in 62 cases, and pulmonary embolism developed in 9 of these cases. We conclude that surgical treatment is effective in treating angiomyolipoma with tumor thrombus...

The vessels supplying the lungs include the pulmonary arteries, pulmonary veins, and bronchial arteries. The segmental and sub segmental pulmonary arteries parallel the bronchi and are named according to the bronchopulmonary segments they supply. There are however considerable anatomic variations, particularly in the upper lobes with variations in number or presence of accessory arteries from adjacent segments. The subsegmental pulmonary vein branches, run within interlobular septa and do not parallel the segmental or sub segmental pulmonary artery branches and bronchi...

Chronic venous insufficiency (CVI) is a multifactorial disease, commonly caused by valvular incompetence (clinically diagnosed by venous reflux) and venous hypertension. The incidence of these factors clearly increases with patient age, and aging is one of the risk factors involved. The activity of the PI3K/Akt/mTOR pathway is considered fundamental in vascular pathologies, and understanding its involvement would help in the development of possible therapeutic targets. This is an observational, analytical, and prospective cohort study that reviewed 110 patients with CVI scheduled to undergo stratified saphenectomy...
