OBJECTIVES: The aim is to examine trends in procedural indication, arterial beds treated, and device usage in peripheral arterial interventions (PVIs). BACKGROUND: There is little data on indication, vascular beds treated and devices utilized for peripheral arterial interventions. METHODS: We used data from 43 hospitals participating in the BMC2 VIC registry. PVIs were separated by year and divided by arterial segment. Lower extremity PVIs were subclassified as having been performed for claudication or critical limb ischemia (CLI)...

Background Phenylhydrazine (PHE) in experimental animal models has been widely reported to cause haemolytic anaemia, via the induction of oxidative stress and thus causing deleterious cardiovascular complications. Hence, this study was designed to evaluate the possible modulatory role of melatonin (MLT) or vitamin C when co-administered with PHE. Methods Anaemia was established with PHE administration. MLT or vitamin C was co-administered with PHE. Haematological parameters, markers of oxidative stress, enzymic and non-enzymic antioxidants, blood pressure and electrocardiograms were assessed...

BACKGROUND: Ultrasound screening shows a clinical benefit in reducing abdominal aortic aneurysm (AAA)-related mortality. However, its cost-effectiveness remains unclear. Understanding the relationship between risk factors and AAA is important to maximize the benefit of AAA screening. However, risk factors for AAA have not been reported in Korea. The purpose of this study was to determine the prevalence of and risk factors for AAA among the Korean population. METHODS: The study population consisted of patients >50 years of age who consented for AAA screening...

OBJECTIVE: High paraaortic lymph nodes superior to the renal vein are often involved by metastasis from advanced ovarian cancer, but are difficult to dissect. We developed a novel surgical technique for removing these nodes. METHODS: The ascending colon is displaced from the right paracolic gutter. A retroperitoneal incision is made cranially from the ileocecal region along Monk's white line (fusion fascia) dorsal to the ascending colon. Incising the fusion fascia toward the root of the right renal vein from inside Gerota's fascia allows separation of the right kidney and mobilization of the ascending colon, partly exposing the inferior vena cava...

OBJECTIVE: The effect of gender on outcomes after lower extremity revascularization is controversial. The aim of our systemic review and meta-analysis was to evaluate the gender-related outcomes after peripheral vascular interventions. METHODS: We systematically searched MEDLINE, Embase, Cochrane Database, and Scopus to identify studies comparing outcomes after revascularization according to gender. A random-effects model was used to pool outcomes. Time-to-event data were reported using hazard ratios (HRs) and dichotomous data were presented using odds ratios (ORs)...

Liddle's syndrome, an autosomal dominant form of monogenic hypertension, is characterized by salt-sensitive hypertension with early penetrance, hypokalemia, metabolic alkalosis, suppression of plasma rennin activity and aldosterone secretion, and a clear-cut response to epithelial sodium channel blockers but not spironolactone therapy. Here, we describe the case of a 16-year-old boy patient with resistant hypertension (maintain 170-180/100-110 mm Hg after administration four kinds of antiypertensive drugs) and severe hypokalemia...

Glucagon-like peptide-1 (GLP-1, GLP-17-36amide) and its sister peptide glucagon-like peptide 2 (GLP-2) influence numerous intestinal functions and GLP-2 greatly increases intestinal blood flow. We hypothesized that GLP-1 also stimulates intestinal blood flow and that this would impact on the overall digestive and cardiovascular effects of the hormone. To investigate the influence of GLP-1 receptor agonism on mesenteric and renal blood flow and cardiovascular parameters, we carried out a double-blinded randomized clinical trial...

INTRODUCTION: Chronic aortic occlusion usually occurs from the infrarenal branch to the terminal aorta. We report the case of a patient with an occlusion that began at the suprarenal artery, and there was also occlusion of the superior mesenteric artery and extreme stenosis of the celiac artery. Antegrade bypass from the ascending aorta to the common hepatic artery was performed. PRESENTATION OF CASE: A 59-year-old patient presented to our hospital with uremia due to acute anuric renal failure and anorexia...

BACKGROUND: In aging populations with an ever-growing burden of risk factors such as obesity, diabetes, and hypertension, chronic kidney disease (CKD) is on the rise. However, little is known about its exact prevalence among elderly adults, and often albuminuria is not included in the definition of CKD. Moreover, novel equations for the estimated glomerular filtration rate (eGFR) have recently emerged, which have not been applied comprehensively to older adults. Data on CKD awareness among the elderly are sparse...

Sex differences have been identified in various biological processes, including hypertension. The mineralocorticoid signaling pathway is an important contributor to early arterial hypertension, however its sex-specific expression has been scarcely studied, particularly with respect to the kidney. Basal systolic blood pressure (SBP) and heart rate (HR) were measured in adult male and female mice. Renal gene expression studies of major players of mineralocorticoid signaling were performed at different developmental stages in male and female mice using reverse transcription quantitative PCR (RT-qPCR), and were compared to those of the same genes in the lung, another mineralocorticoid epithelial target tissue that regulates ion exchange and electrolyte balance...

In renal transplant, multiple renal arteries in a donor require meticulous vascular reconstruction for successful allograft function in the recipient. Presence of more than 4 renal arteries is usually considered to be a relative contraindication for proceeding with renal donation. We report a living-donor renal transplant procedure where preoperative radiologic imaging of the donor showed 3 left renal arteries. Two additional arteries were identified intraoperatively. All 5 arteries were reconstructed during the back-table procedure, and the allograft was implanted in the recipient...

INTRODUCTION: Kidney transplantation (KT) is the preferred treatment for patients with end-stage renal disease (ESRD). To reduce the morbidity of the open surgery, a robotic-assisted approach has been recently introduced. Our aim is to evaluate surgical and functional results on 17 cases of robotic-assisted kidney transplantation (RAKT) performed at the same institution. MATERIALS AND METHODS: From July 2015 to June 2016, we performed 17 cases of RAKT from living donors in pre-emptive patients, who underwent laparoscopic nephrectomy...

Crossed renal ectopia is a rare congenital anomaly, where one of the kidneys crosses the midline and lies opposite to the site of its normal ureteral insertion. Ninety percent of crossed ectopic kidneys are fused to their ipsilateral uncrossed kidney. Crossed renal ectopia without fusion is rare. We present the case of a 53-year-old male with an unusual incidental finding of crossed nonfused renal ectopia, with the left ectopic kidney lying anterior to the right kidney without fusion. The ectopic kidney had dual arterial supply: one from the aorta and another from the right renal artery...

Polyarteritis nodosa (PAN) is a necrotising vasculitis that involves medium and small vessels. PAN generally presents with constitutional, cutaneous, neurological, renal and gastrointestinal manifestations. However, PAN initially involving a single organ/system is uncommon. Here, we present a 42-year-old man who was hospitalised because of severe right upper quadrant abdominal pain that started 2 months before. Physical examination was remarkable for right upper quadrant abdominal tenderness. Abdominopelvic CT showed lymphadenopathy but no hepatic, gallbladder, pancreatic, intestinal or renal abnormalities...

Damage to endothelial cells contributes to acute kidney injury (AKI) by leading to impaired perfusion. Endothelial colony-forming cells (ECFCs) are endothelial precursor cells with high proliferative capacity, pro-angiogenic activity, and in vivo vessel forming potential. We hypothesized that ECFCs may ameliorate the degree of AKI and/or promote repair of the renal vasculature following ischemia/reperfusion (I/R). Rat pulmonary microvascular ECs (PMVEC) with high proliferative potential were compared with pulmonary artery ECs (PAEC) with low proliferative potential in rats subjected to renal I/R...
