#1
Tracy Hagerty, Patrick Geraghty, Alan C Braverman
OBJECTIVE: Marfan syndrome (MFS) leads to aortic root aneurysm, while descending thoracic aortic aneurysm (TAA) occurs less commonly. Abdominal aortic aneurysm (AAA) is rarely reported in MFS. Risk factors for AAA are poorly understood and there are no guidelines for AAA screening in MFS. We sought to characterize AAA among Marfan patients in our center. METHODS: The records of 12 adults with MFS and AAA disease were reviewed. Clinical features, imaging, operative reports, and outcomes were analyzed...

PURPOSE: To report a hybrid technique for the treatment of a suprarenal aortic aneurysm (SAA) in a patient with iliac occlusive disease. Initially an infrarenal aorto-bifemoral surgical graft was implanted, followed by deployment of a fenestrated bifurcated stent-graft at the suprarenal part of the aorta. CASE REPORT: A 69-year old man presented with a 51-mm saccular SAA and iliac occlusive disease with intermittent claudication. Both common iliac arteries had been previously treated with kissing stents...

BACKGROUND: These last years, considerable attention has been given to renal issues following endovascular aortic repair (EVAR) but acute kidney injury (AKI) also remains one of the most frequent complications following open repair (OR). OBJECTIVES: Since AKI definition has evolved, our aim was to review the aetiology, incidence, classifications and consequences of AKI after OR for intact abdominal aortic aneurysm (AAA). METHODS: A review of the English language literature published between 2004 and 2016 was conducted according to the PRISMA criteria...

BACKGROUND: Ovation Aortic Stent-Graft System is a new device for the endovascular treatment of Abdominal Aortic Aneurysms achieving fixation via a 35-mm long, rigid ancored suprarenal stent and sealing stent at the infrarenal level by a means of a polymer-filling pair of inflatable O-rings which cause narrowing of flow lumen and regional stenosis. Thus, concerns have been raised regarding hemodynamic consequences associated with this new desing . Our preliminary report showed no significant increase of aortic pulse wave velocity (aPWV) immediately after implantation of the Ovation in 3 patients...

Acute kidney injury (AKI) remains an independent risk factor for mortality and morbidity after vascular surgery (affecting the renal arteries) or aortic surgery (requiring suprarenal aortic clamping). These types of vascular surgery produce renal ischemia/reperfusion (I/R) injury, a common cause of AKI. The present studies aimed at monitoring the course of renal I/R injury at the cellular level and investigating the efficacy of long-term preoperative and single-shot intraoperative administration of sodium pentosan polysulfate (PPS) to protect renal tissue from acute I/R injury both in native and diabetic kidneys in rats...

OBJECTIVE: Managing symptomatic chronic type B aortic dissection (SCTBAD) by the Streamliner Multilayer Flow Modulator (SMFM) stent (Cardiatis, Isnes, Belgium) is akin to provisional structural support to induce complete attachment of the dissection flap, but with the ability of aortic remolding. This study investigated the SMFM's capability to enact healing of SCTBAD. METHODS: Clinical data for 12 cases comprising preoperative and postoperative treatment of SCTBAD were obtained from a multicenter database hosted by the Multilayer Flow Modulator Global Registry, Ireland...

OBJECTIVE: Assessment of a simple layer peritoneal tube used as an autogenous inferior vena cava replacement. BACKGROUND: Extensive en-bloc multivisceral resection including major vessels is effective in selected abdominal malignancies, but the need for vascular reconstruction represents a surgical challenge. We describe the use of autologous peritoneum for caval replacement. METHODS: Autogenous parietal peritoneum without fascial backing was harvested and tubularized to replace the inferior vena cava (IVC) in four patients with complex abdominal tumors...

INTRODUCTION: During adrenal venous sampling (AVS) procedure, radiologists administer a contrast agent via the catheter to visualize the proper catheter position. MATERIALS AND METHODS: A patient with primary aldosteronism diagnostic-hypothesis was admitted for AVS. A venogram was performed to
confirm the catheter's position with 2mL of Iopamidol 300 mg/mL. Samples were collected with syringe connected to a hydrophilic coated catheter by low-pressure aspiration from each of the four collection sites: inferior vena cava in the suprarenal portion, inferior vena cava in the infrarenal portion, left adrenal vein, and right adrenal vein; then immediately transferred from syringe to tubes with gel separator...

A man aged 33 years presented with a 3-day history of left-sided testicular discomfort. Clinical examination revealed a large left-sided varicocele. He was referred for a testicular ultrasound, which demonstrated a moderate left-sided varicocele and an associated large suprarenal mass. An urgent (CT) scan was arranged which confirmed this, with associated compression of adjacent structures, including the left kidney and left renal vessels. The patient was admitted 1 week following the CT scan with features of sepsis...

BACKGROUND: Abdominal aortic aneurysm (AAA) affects more than 5% of the population in developed countries. To study the formation and progression of AAA, we developed a non-invasive method to analyse regional aortic stiffness to monitor the formation and progression of AAA. METHODS: Saline or Angiotensin II (AngII) was subcutaneously infused in apolipoprotein E knockout (ApoE(-/-)) mice for 28 days; a high-resolution imaging system was used to identify changes in arterial stiffness measured by pulse-wave velocity (PWV) and aortic lumen diameter in the suprarenal aorta...

Angiogenesis and inflammation are implicated in aortic aneurysm and atherosclerosis and regulated by angiopoietin-2 (Angpt2). The effect of Angpt2 administration on experimental aortic aneurysm and atherosclerosis was examined. Six-month-old male apolipoprotein E deficient (ApoE(-/-)) mice were infused with angiotensin II (AngII) and administered subcutaneous human Fc-protein (control) or recombinant Angpt2 (rAngpt2) over 14 days. Administration of rAngpt2 significantly inhibited AngII-induced aortic dilatation and rupture of the suprarenal aorta (SRA), and development of atherosclerosis within the aortic arch...

Pheochromocytoma, a neuroendocrine tumor of the adrenal medulla, arising from chromaffin cells, usually presents with the clinical triad of paroxysmal headache, profuse sweating and palpitations, associated with labile hypertension. Here, we present the case of an adult male with an unusual manifestation of pheochromocytoma in the form of acute pain abdomen with nausea and abdominal guarding, mimicking acute peritonitis. He had fluctuating blood pressure recordings. On subsequent investigation, a mass lesion in the left suprarenal area on an abdominal CT scan and a 24-hour urinary metanephrine assay confirmed the diagnosis of pheochromocytoma...

We describe a case of metastatic clear cell renal cell carcinoma with intensely tracer concentrating lesions in left suprarenal region, mediastinal lymph nodes, lytic bone lesions, thyroid nodules, and mild abnormal tracer-avid lung nodules in Ga-prostate-specific membrane antigen (PSMA) PET/CT. On the other hand F-FDG PET/CT showed mild to no significant abnormal uptake in these lesions. Complimentary uptake pattern was observed in Ga-PSMA and F-FDG PET images in thyroid lesions and D5 vertebral lesion. This case highlights the possibilities of imaging clear cell renal cell carcinoma with Ga-PSMA and opens the possibility of treatment with Lu-PSMA...

OBJECTIVE: Endovascular aneurysm repair (EVAR) is widely used with excellent results, but its infectious complications can be devastating. In this paper, we report a multicenter experience with infected EVAR, symptoms, and options for explantation and their outcome. METHODS: We have reviewed all consecutive endograft explants for infection at 11 French university centers following EVAR, defined as index EVAR, from 1998 to 2015. Diagnosis of infected aortic endograft was made on the basis of clinical findings, cultures, imaging studies, and intraoperative findings...

RATIONALE: Uncontrolled growth of abdominal aortic aneurysms (AAAs) is a life-threatening vascular disease without an effective pharmaceutical treatment. AAA incidence dramatically increases with advancing age in men. However, the molecular mechanisms by which aging predisposes individuals to AAAs remain unknown. OBJECTIVE: In this study, we investigated the role of Sirtuin 1 (SIRT1), a class Ⅲ histone deacetylase, in AAA formation and the underlying mechanisms linking vascular senescence and inflammation...

Importance: Epidural analgesia (EA) is used as an adjunct procedure for postoperative pain control during elective abdominal aortic aneurysm (AAA) surgery. In addition to analgesia, modulatory effects of EA on spinal sympathetic outflow result in improved organ perfusion with reduced complications. Reductions in postoperative complications lead to shorter convalescence and possibly improved 30-day survival. However, the effect of EA on long-term survival when used as an adjunct to general anesthesia (GA) during elective AAA surgery is unknown...

Neuroendocrine chromaffin cells of the adrenal medulla in rat receive excitatory synaptic input through anterior and posterior divisions of the sympathetic splanchnic nerve. Upon synaptic stimulation, the adrenal medulla releases the catecholamines, epinephrine, and norepinephrine into the suprarenal vein for circulation throughout the body. Under sympathetic tone, catecholamine release is modest. However, upon activation of the sympathoadrenal stress reflex, and increased splanchnic firing, adrenal catecholamine output increases dramatically...

OBJECTIVE: The influence of endovascular aneurysm repair (EVAR) on renal function is of high concern. The question whether stent graft fixation type plays a significant role in renal outcome after EVAR is still debated. However, other factors, such as repeated contrast medium exposure, should also be considered. METHODS: We performed a two-center, stratified-cohort case control study to evaluate the influence of last-generation abdominal endografts with suprarenal (SR) vs infrarenal (IR) fixation on renal function...
