Tsunehiro Shintani, Kouji Atsuta, Takaaki Saito
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...

Umbilical artery catheterisation is frequently performed in preterm or critically ill newborn infants for invasive monitoring of blood pressure and blood sampling for laboratory tests. It is associated with well-known complications like catheter-related infections, thromboembolic events and aneurysmal formation of the aorta. In this report, we present another major complication of umbilical artery catheterisation: umbilical artery perforation. This complication occurred in a prematurely born infant and resulted in severe haemorrhagic shock, subsequent renal failure and severe periventricular leukomalacia...

OBJECTIVE: The purpose of this study is to assess differences in patient distress, risk perception, and treatment preferences for incidental renal findings with descriptive versus combined descriptive and numeric graphical risk information. MATERIALS AND METHODS: A randomized survey study was conducted for adult patients about to undergo outpatient imaging studies at a large urban academic institution. Two survey arms contained either descriptive or a combination of descriptive and numeric graphical risk information about three hypothetical incidental renal findings at CT: 2-cm (low risk) and 5-cm (high risk) renal tumors and a 2-cm (low risk) renal artery aneurysm...

Congenital renal artery aneurysm is uncommon. Moreover, renal artery aneurysm concomitant with a congenital renal arteriovenous fistula is extremely rare. Transarterial embolization is the first-line treatment for these conditions. We report a case of a patient with congenital renal artery aneurysm concomitant with a congenital renal arteriovenous fistula of the upper polar left renal artery which was successfully treated by transarterial embolization with coil, glue, and Amplatzer vascular plug.

Background: Polyarteritis nodosa (PAN) is a medium vessel vasculitis which causes significant morbidity and mortality. Usually, it presents with constitutional symptoms with angiographic evidence of aneurysms or segmental stenosis of arteries of mesenteric or renal vasculature. It is exceedingly uncommon for PAN to present with symptomatic progressive intermittent claudication. Case Presentation: We describe a 60-year-old male who presented with rapidly progressive intermittent claudication of his right leg...

Contrast-induced encephalopathy is a very rare complication associated with endovascular treatment of intracranial aneurysms. Patients with renal dysfunction may be prone to developing contrast medium neurotoxicity as a result of delayed elimination of the contrast medium in renal metabolism. This article focuses on our experience with contrast-induced encephalopathy in patients with end-stage renal disease requiring hemodialysis. The authors retrospectively reviewed five patients diagnosed with contrast-induced encephalopathy who underwent aneurysm coil embolization at their institution from January 2006 to December 2015...

Renovascular hypertension (RVH) has deleterious effects on both the kidney and the heart. TGF-β signaling through Smad3 directs tissue fibrosis in chronic injury models. In the 2-kidney 1-clip (2K1C) model of RVH, employing mice on the 129 genetic background, Smad3 deficiency (KO) protects the stenotic kidney (STK) from development of interstitial fibrosis. However, these mice have an increased incidence of sudden cardiac death following 2K1C surgery. The purpose of this study was to characterize the cardiovascular phenotype of these mice...

BACKGROUND: In the era of rising endovascular treatment of thoracoabdominal aortic aneurysms (TAAAs), the analysis of visceral vessel (VV) patency after open surgical repair is crucial to provide a future benchmark between these different approaches. This study reports the late outcomes of a single-center experience with open TAAA repair, focusing on the results of different techniques adopted for renal and splanchnic revascularization. METHODS: Data were analyzed for 382 consecutive open TAAA repairs performed between January 2009 and July 2015 (284 men; mean age, 66 ± 10 years)...

BACKGROUND: Renal artery aneurysm (RAA) is rare and its incidence in the general population remains elusive. There have been few reports on the repair of multiple aneurysms conducted with the Da Vinci robot-assisted surgical platform (Intuitive Surgical Inc., Sunnyvale, CA, USA), especially for those located in renal artery primary bifurcations. CASE PRESENTATION: We report our experience in the surgical management of two expanding right-sided RAAs in a 64-year-old man using a robot-assisted laparoscopic approach...

Abdominal aortic aneurysm (AAA) with associated horseshoe kidney (HSK) poses a technical challenge when performing conventional open surgical repair because of possible complications including renal infarction, neuralgia, and collecting system disruption. Endovascular aortic repair (EVAR) is considered the first-line treatment for this pathology, allowing for aneurysm repair without isthmus bisection. However, whether to sacrifice commonly presenting aberrant renal arteries during EVAR is a point of controversy...

Saphenous vein graft (SVG) aneurysms (SVGA) after renal transplantation represents a rare vascular complication with subsequent challenging multidisciplinary treatment. We present a case of a 30-year-old female who received a live donor kidney transplantation for end-stage renal disease that was caused due to the hemolytic uremic syndrome. Postoperatively, an insufficient graft perfusion due to an arterial kinking was noted and repaired using an autologous SVG interposition. Ten years later, a 3-cm aneurysm of the SVG at the anastomotic site with the common iliac artery was discovered...

The presence of diabetes mellitus is rarely addressed in acute lower limb ischaemia (ALLI). The aim of this study was to evaluate the outcome of local intra-arterial thrombolysis for ALLI in patients with diabetes mellitus (DM). Outcome of all thrombolytic events performed in an endovascular first-strategy centre during a 13-year period between 2001 and 2013 in patients with ALLI were followed to January 2017. A propensity score adjusted analysis was performed to evaluate results in patients with (n = 83) versus without (n = 316) DM...

Renal artery aneurysm has an incidence of lower than one in 1000 of the general population. The risk of aneurysm rupture increases during pregnancy due to hormonal and hemodynamic changes. Therefore, these patients often refer to physicians with abdominal pain that is followed by shock. We report the case of a 41-year-old multiparous woman who was referred with symptoms of epigastric pain and hemorrhagic shock, a week after her vaginal delivery. She was diagnosed with renal artery aneurysm in ultrasonography...

Intracranial aneurysms (IAs) that undergo rupture causing subarachnoid hemorrhage (SAH), are common in young patients with coarctation of the aorta (CoA), but rarer in middle-aged and elderly patients. The pathogenesis of IAs associated with CoA remains unclear. We report the case of a 50-year-old woman who presented with SAH. On evaluation, six IAs were distributed among the anterior communicating artery (ACoA) (ruptured), distal segments of both anterior cerebral arteries (ACA), the left internal carotid artery (ICA), the bifurcation of the left middle cerebral artery (MCA)/MCA early branch, and the inferior trunk of the left MCA...
