To investigate the relation of pressure and vascular wall thickening in hypertension, we coarcted the abdominal aorta upstream to the renal arteries in 14 rats. Sham-coarcted (n = 16) and two-kidney, one-clip (Goldblatt) hypertensive rats (n = 13) served as controls. Tail, femoral, and carotid arterial pressures rose (p less than 0.01) in the two-kidney, one-clip hypertensives; only carotid pre...

left flank pain. She had been taking angiotensin receptor blockers and beta blockers for the past six years. Her blood pressure was 140/90 mmHg, pulse rate 76/min, hemoglobin 12.3 g/dL (reference range, 12-18 g/dL), and creatinine level 0.5 mg/dL (reference range, 0.5-1.3 mg/dL). Urinalysis revealed microscopic hematuria and no proteinuria. A palpable abdominal mass was detected and pulsation c...

In anesthetized dogs the peripheral ends of the cut sympathetic chains (LGi-LG2 level) were stimulated while blood pressure was held constant artificially, and the diameter of the abdominal aorta was monitored. Bilateral stimulation induced a reduction in diameter that was directly related to the stimulation frequency. Maximal diameter reduction of the aorta above the iliac bifurcation averaged...

PURPOSE To investigate the relationship between the vascular diameter and the extent and histologic characteristics of atherosclerosis in the thoracic and abdominal aortas of patients who died of atherosclerotic disease. METHOD We measured the vascular diameter and evaluated the percentage atrophy of the medial layer of the thoracic and abdominal aortas of 19 patients who died due to atherosc...

Introduction renal arteries. The proximal neck of the aneurysm was 24 mm long and 23 mm wide, without thrombus or Endoluminal repair of infrarenal aneurysms of the calcifications, and consequently fit for endovascular abdominal aorta is still controversial. Much unfixation (Fig. 2). Preoperative kidney function was certainty continues to exist about its proper application normal (urea: 5.5 mmol...

BACKGROUND We designed this study to expand the usage of ultrasound to detect early occurrence of hypovolemia. We explore the potential use of inferior vena cava (IVC) and abdominal aorta (AA) diameter index (IVC:AA) measured ultrasonographically to detect class 1 hypovolemic shock with blood loss less than 15%.ᅟ METHODS The aim of this study was to determine the changes in the diameter of in...

AIMS Thoracic aortic aneurysm (TAA) is potentially life-threatening and requires close follow-up to prevent aortic dissection. Aortic stiffness and size are considered to be coupled. Regional aortic stiffness in patients with TAA is unknown. We aimed to evaluate coupling between regional pulse wave velocity (PWV), a marker of vascular stiffness, and aortic diameter in TAA patients. METHODS In...

Umbilical artery catheters have been associated with thrombotic complications, such as partial or complete occlusion in the aorta, the renal arteries, and other blood vessels. There have been few reports of the long-term consequences of either symptomatic or asymptomatic thrombi. We report a patient, now 22 years of age, born with a normal aorta, who developed hypertension at the age of 2 month...

uring the dissection of a 38-year-old female cadaver, an ovarian artery originating from an accessory renal artery is exposed on the right side (Figure 1). The proximal one of the 2 arteries supplying the kidney was emerging from the abdominal aorta at L2 vertebra level and 12.6mm below the celiac trunk. The diameter of this artery was 5.5mm and was passing behind the inferior vena cava. Then, ...

Introduction The abdominal aorta begins at 12th thoracic vertebra, and it descends anterior to the lumbar vertebrae, and bifurcates at the 4th lumbal vertebral body. It supplies all the abdominal organs, abdominal walls, gonads, and lower extremity [1]. In the usual vasculature, celiac trunk is divided into three branches: common hepatic artery (CHA), splenic artery (SA), and left gastric arter...
