INTRODUCTION: Previous studies of the safety of renal autotransplantation (RAT) have been limited by a lack of evidence. Because of the influence of the opposite kidney, it is difficult to evaluate actual renal function. This study evaluated the actual results of RAT by collecting only cases involving a solitary kidney. METHODS: Between September 1, 1999, and November 30, 2015, 9 RAT procedures were performed in 9 patients with a solitary kidney. We retrospectively evaluated medical data collected prospectively...

Abdominal aortic aneurysm (AAA) is a degenerative disease of the aortic wall with potentially fatal complications. Open repair (OR) was considered the gold standard, until the emergence of endovascular aneurysm repair (EVAR), which is less invasive and equally (if not more) effective. As the popularity of endovascular procedures grows, related complications become more evident, with kidney damage being one of them. Although acute kidney injury (AKI) following EVAR is relatively common, its true incidence is still uncertain...

BACKGROUND: A decrease in serum low-density lipoprotein cholesterol (LDL-C) is well documented after acute stress. Plasma proprotein convertase subtilisin kexin 9 (PCSK9), which promotes degradation of low-density lipoprotein receptor (LDL-R) resulting in reduced plasma clearance of low-density lipoproteins (LDL) and an increase in serum LDL-C, would be predicted to decrease. Yet, a few studies have demonstrated an increase 1-8 days after acute stress. Our objective was to assess the earlier status of plasma PCSK9, within the first 24 hours of onset of stress...

Background: Although endovascular repair for abdominal aortic aneurysm has been found to be beneficial in very elderly patients, some patients have contraindications to this procedure. For nonagenarians, the results of open repair remain unclear. The purpose of this study was to compare the outcomes of open vs. endovascular repair for abdominal aortic aneurysm in nonagenarian patients. Methods and Results: Fourteen patients undergoing open surgical repair and 24 undergoing endovascular repair for abdominal aortic aneurysm were evaluated...

Herein, we report a rare case of type B aortic dissection that occurred after endovascular aortic aneurysm repair (EVAR). A 66-year-old man underwent successful EVAR for an abdominal aortic aneurysm (AAA). Computed tomography (CT) 2 years after EVAR showed a type B aortic dissection with stent-graft migration and AAA expansion. Juxtarenal aortic expansion precluded simple stent-graft placement. He underwent hepato-spleno-renal bypass followed by stent-graft placement just below the superior mesenteric artery...

A 69-year-old man with a type IA endoleak that developed approximately 21 months after endovascular abdominal aortic aneurysm repair (EVAR) of a 46 mm diameter aneurysm was referred to our department. He had impaired renal function, Parkinson's disease, and previous cerebral infarction. Computed tomography angiography showed a type IA endoleak with neck dilatation and that the aneurysm had grown to 60 mm in diameter. We decided to perform aortic banding. The type IA endoleak disappeared after banding and the patient was discharged on postoperative day 10...

OBJECTIVE: Isolated spontaneous dissection of the superior mesenteric artery (SMA) and celiac artery (CA) remains a rare condition; however, it has been increasingly noted incidentally on diagnostic imaging. The purpose of this study was to examine the natural history and outcomes of patients presenting with isolated spontaneous mesenteric artery dissection (SMAD). We hypothesized that most SMADs can be treated nonoperatively. METHODS: This was a single-center retrospective review of patients presenting with the diagnosis of SMAD between 2006 and 2016...

BACKGROUND: An abdominal aortic aneurysm (AAA) is a focal dilation of the abdominal aorta and is associated with a risk of fatal rupture. Experimental studies suggest that myo-inositol may exert beneficial effects on AAAs through favourable changes to biological pathways implicated in AAA pathology. The aim of the Inositol in the MAnaGemENt of abdominal aortic aneurysm (IMAGEN) trial is to assess if myo-inositol will reduce AAA growth. METHODS/DESIGN: IMAGEN is a multi-centre, prospective, parallel-group, randomised, double-blind, placebo-controlled trial...

In patients with abdominal aortic aneurysms (AAA) and complete iliac occlusion, endovascular aortic aneurysm repair (EVAR) using a bifurcated stent graft has clear advantages over aortouniiliac stent grafts. Bifurcated stent grafts had improved hemodynamic flow and increased primary and secondary patency rates compared with aortouniiliac stent grafts. The use of aortouniiliac stent grafts with femorofemoral crossover bypass is associated with complications including infection of the prosthesis, steal phenomenon, and the associated difficulties for further endovascular access at the site of the femoral anastomosis...

Abdominal aortic aneurysm (AAA) is an uncommon entity with high mortality. Etiologically, they are classified as inflammatory and infective (mycotic), the latter being less common. Clinical presentation, laboratory investigations, and treatment for these may considerably overlap. However, choice of management and the need for surgical intervention depends on factors such as size and progression of aneurysm, persistent symptoms, and presence or absence of distant pathology. Although computed tomography (CT) is the gold standard for AAA, in selected cases, especially in infected AAA, fluorodeoxyglucose positron emission tomography-CT can provide valuable information...

BACKGROUND: The implications of intraluminal thrombus (ILT) in abdominal aortic aneurysm (AAA) are currently unclear. Previous studies have demonstrated that ILT provides a biomechanical advantage by decreasing wall stress, whereas other studies have associated ILT with aortic wall weakening. It is further unclear why some aneurysms rupture at much smaller diameters than others. In this study, we sought to explore the association between ILT and risk of AAA rupture, particularly in small aneurysms...

BACKGROUND: Abdominal aortic aneurysm (AAA) refers to localized dilation of abdominal aorta. AAA is largely asymptomatic, but aneurysmal rupture results in a high mortality rate. AAA with a diameter greater than 55 mm carries a high risk of rupture. There are currently no known medical treatments effective in limiting the growth of small AAA. OBJECTIVE: To review the current status of and challenges faced in limiting AAA growth. METHODS: Data from human investigations and animal model studies were summarized...

Accumulating evidence suggests an important role of Phosphatidylinositol 3-kinease (PI3K) pathway in inflammatory cells infiltration. Given  the essential role of inflammatory cells infiltration during the formation and progression of abdominal aortic aneurysm (AAA), to investigate the possibility of preventing AAA formation and progression via targeting PI3K is anticipated. Here, experimental AAAs was created in rats by transient intraluminal porcine pancreatic elastase (PPE) infusion into the infrarenal aorta firstly...
