BACKGROUND Vasoconstrictor responses to serotonin are augmented in monkeys with diet-induced atherosclerosis and improve after 18 months of normal diet. We tested the hypothesis that functional improvement may occur early during regression, before evidence of structural improvement. METHODS AND RESULTS Responses of the iliac artery to serotonin were measured by quantitative angiography and a ...

INTRODUCTION Endovascular aortic repair (EVAR) has gained prominence as a means of treating aortic disease, with lower perioperative morbidity and mortality compared to open surgery. This article aimed to describe the experience of two tertiary hospitals in a Southeast Asian population. METHODS A retrospective review of 100 consecutive patients undergoing EVAR in two hospitals in Singapore wa...

BACKGROUND The contemporary obstetrician is increasingly put to the test by rising numbers of pregnancies with morbidly adherent placenta. This study illustrates our experience with prophylactic bilateral internal iliac artery occlusion as part of its management. METHODS Between January 2011 to January 2014, 13 consecutive patients received the intervention prior to scheduled caesarean delive...

A 77-year-old Caucasian male with a history of hypertension presented with sudden onset of lower back pain, nausea, and vomiting. Initial vital signs included a pulse rate of 104 beats/minute, a blood pressure of 117/72 mm Hg, and pulse oximetry of 95% on room air. Abdominal examination revealed a midline pulsatile mass and bruit. The patient had bilateral lower extremity edema, which was worse...

The contribution of the alpha-1B adrenergic receptor (AR) to vascular smooth muscle contraction has been assessed using a combination of immunological, molecular biological and pharmacological approaches. A subtype-selective antibody detected alpha-1B immunoreactivity in the medial layer of the aorta, caudal, femoral, iliac, mesenteric resistance, renal and superior mesenteric arteries. Recepto...

OBJECTIVE We prospectively compared patients' tolerance for and the usefulness of carbon dioxide (CO2) with iodinated contrast material in the study of lower limb arteries in 30 patients. SUBJECTS AND METHODS We systematically performed digital subtraction angiography with electronic injection of CO2 (injection average, 330 ml) and digital subtraction angiography with iodinated contrast mater...

BACKGROUND We investigated the relationship between the mode and duration of iliac artery anastomosis and acute femoral neuropathy (AFN). METHODS A retrospective analysis was performed for 83 AFN cases from 6 transplantation centers in China. The incidence and nature of dysfunction of AFN were classified based upon the duration of iliac arterial anastomosis. No prisoners were used, and no org...

Cases of vascular anomalies of the iliac and femoral vessels are rare. We report a complete absence of the right common iliac artery in a 21-year-old woman, incidentally discovered by CT during the work-up for acute abdominal pain. A network of prominent collateral arteries reconstituted the distal portion of the right external iliac artery and the common femoral artery, forming the arterial su...
