Hypertestosteronism as part of hyperandrogenic states in women is generally defined as abundance of male hormones (in this case abundance of testosterone). Spectrum of clinical symptoms include menstrual disorders, amenorrhoea, different range of hirsutism and virilization. Statistically, most androgen secreting tumors are ovarian aetiology (testosterone secreting tumors located in suprarenal gland are very rare). This rare tumor may produce excess amounts of testosterone, as well as its precursor androstenedione...

Introduction: Iodinated contrast media completion angiography (ICM-A) may underestimate the presence of type II endoleak (ELII) after endovascular aortic repair (EVAR), particularly if they are at low flow. Contrast-enhanced ultrasound (CEUS) has been proposed as the gold standard in ELII detection during EVAR follow-up. Intraprocedural carbon dioxide (CO2 ) angiography has been shown to be useful in this setting; however no comparative studies including these three techniques are currently available...

Aging leads to central artery stiffening and associated hemodynamic sequelae. Because healthy arteries exhibit differential geometry, composition, and mechanical behaviors along the central vasculature, we sought to determine whether wall structure and mechanical function differ across five vascular regions-the ascending and descending thoracic aorta, suprarenal and infrarenal abdominal aorta, and common carotid artery-in 20 versus 100-week-old male wild-type mice. Notwithstanding generally consistent changes across these regions, including a marked thickening of the arterial wall, diminished in vivo axial stretch, and loss of elastic energy storage capacity, the degree of changes tended to be slightly greater in abdominal than in thoracic or carotid vessels...

Osteoprotegerin (OPG), additionally termed tumor necrosis factor receptor superfamily member 11B, is produced by vascular smooth muscle cells (VSMCs) and endothelial cells in the vasculature, and its release may be modulated by pro‑inflammatory cytokines, including interleukin‑1β and tumor necrosis factor‑α. The present study investigated the effects of treatment with low‑dose human recombinant OPG on abdominal aortic aneurysm (AAA) development in mice. Mice were treated with 1 µg human recombinant OPG four times (or vehicle) for 2 weeks prior to inducing AAA...

When the Budd-Chiari syndrome (BCS) lesion extends to the inferior vena cava (IVC) or the orifices of the hepatic vein, the thickened IVC and/or hepatic vein wall must be removed and IVC reconstruction is required in living-donor liver transplantation (LDLT). In various reports about IVC resection in LDLT for BCS, there are none about left lobe liver transplantation with reconstruction of the retrohepatic IVC (rhIVC). To overcome removal and reconstruction of the rhIVC in LDLT for BCS, we introduced a composite IVC graft that is applicable to both right and left lobe partial liver grafts for LDLT for BCS...

Perivascular adipose tissue (PAT) is associated with vascular homeostasis; however, its causal effect on atherosclerosis currently remains undefined. Here, we investigated the effect of experimental PAT transplantation on atherosclerosis. The thoracic periaortic adipose tissue (tPAT) was dissected from 16-week-old wild-type mice and transplanted over the infrarenal aorta of 20-week-old apoE deficient (apoE-/- ) mice fed high-cholesterol diet for 3 months. Oil-red O staining after 4 weeks showed a significant 20% decrease in the atherosclerotic lesion of suprarenal aorta compared with that of sham control mice, while that of infrarenal aorta showed no difference between the two groups...

OBJECTIVES: Previous studies have reported increased perioperative mortality of nonruptured symptomatic abdominal aortic aneurysms (Sx-AAA) compared with asymptomatic elective AAA (E-AAA) repairs, but no long-term-outcomes have been reported. We sought to compare long-term outcomes of Sx-AAA and E-AAA after repair at a single academic institution. METHODS: Patients receiving AAA repair for Sx-AAA and E-AAA from 1995 through 2015 were included. Ruptured AAA and suprarenal or thoracoabdominal AAA were excluded...

OBJECTIVE/BACKGROUND: Abdominal aortic aneurysm (AAA) is an individual and socioeconomic burden in today's ageing society. Treatment relies on surgical exclusion of the dilated aorta by open or endovascular repair. For research purposes, animal models are necessary and the elastase induced aneurysm model closely mimics end stage human aneurysm disease. To improve the translational value of this model, four modifications to the classic elastase perfusion procedure (PPE) in relation to human aneurysm morphology were conducted...

Primary simultaneous multiple organs teratomas are extremely rare. They usually arise in the gonads, and only 1-3 % of them arise in the mediastinum. We present a case of simultaneous multiple organs immature teratomas who was admitted to Razi hospital because of cough, dyspnea, and left-side supraclavicular mass. Computed tomography (CT) showed a big mass with multiple high densities, nodular, semi-solid, heterogenic structures on the left side of the neck, left-side anterior mediastinum, right-side middle mediastinum and right-side suprarenal region...

BACKGROUND: Risk factors for postoperative cognitive decline after noncardiac surgery are multifactorial and poorly understood. Evidence suggests that perioperative microembolic damage to the brain on movement of wires and catheters during endovascular aortic procedures may play an important role. Endovascular aortic aneurysm repair requires invasive manipulation of wires and cannulas within the aorta, but research into cerebral emboli during aortic aneurysm repair and cognitive or neurologic injury is scarce and limited to thoracic aneurysms...

Knowledge of the morphological variations within the abdominal cavity is significant for all medical practitioners planning surgery. This report presents the rare origin of a common trunk for the right inferior phrenic artery, and superior and inferior suprarenal artery from the right renal artery. An accessory hepatic artery was found, which served as a branch of the right inferior phrenic artery. The diameter of the common trunk was 3.95 mm, and the diameters of the inferior and superior suprarenal arteries were 1...

INTRODUCTION: Historically, the open approach to the abdominal aorta has been transperitoneal (TP). In comparison, a retroperitoneal (RP) incision exposes the lateral wall of the suprarenal aorta for clamp application and midline structures such as the duodenum and pancreas are not encountered. Proximal clamp position for open repair of juxtarenal abdominal aortic aneurysm (JR-AAA) is suprarenal, supra-superior mesenteric, or supraceliac. While RP and TP approaches have previously been compared for physiological reasons, there are currently no randomized controlled trials comparing these methods from an anatomical perspective...
