Single Branch Endovascular Aortic Repair Procedure for an Abdominal Aortic Aneurysm in a Patient With Horseshoe Kidney: A Case Report.

Introduction: Horseshoe kidney (HK) is an anatomical variant characterised by abnormalities in the position, rotation, and vascular supply of the kidney, with functioning renal masses on both sides of the vertebral column fused together at the isthmus. Due to the altered pattern of kidney vasculature, endovascular aortic repair for aortic abdominal aneurysm (AAA) in the presence of HK requires vascular anatomy specific planning.

Report: A 68 year old male, with multiple comorbidities, presented with an asymptomatic AAA and HK.

Cholesteryl hemiazelate identified in CVD patients causes in vitro and in vivo inflammation.

Oxidation of PUFAs in LDLs trapped in the arterial intima plays a critical role in atherosclerosis. Though there have been many studies on the atherogenicity of oxidized derivatives of PUFA-esters of cholesterol, the effects of cholesteryl hemiesters (ChEs), the oxidation end products of these esters, have not been studied. Through lipidomics analyses, we identified and quantified two ChE types in the plasma of CVD patients and identified four ChE types in human endarterectomy specimens.

Does autosomal dominant polycystic kidney disease increase the risk of aortic aneurysm or dissection: a point of view based on a systematic review and meta-analysis.

Autosomal Dominant Polycystic Kidney Disease (ADPKD) has several renal and extra-renal manifestations. Studies have reported a higher incidence of aortic aneurysms (AAs)/aortic dissections (ADs) in these patients, and we believe ADPKD should be considered as a risk factor for AA/AD. In order to support our opinion we conducted a systematic review and meta-analysis analyzing the risk of AA/AD in ADPKD patients.

A catastrophic seronegative anti-phospholipid syndrome: case and literature review.

Background: Antiphospholipid Syndrome (APS) is a multisystemic autoimmune disease characterized by arterial and venous thrombosis and / or obstetric morbidity in the presence of at least one circulating anti-phospholipid antibody.

The aim of this study was to report the clinical outcomes of a single-institution experience using hybrid aortic arch repair.

A single-center experience in the eversion femoral endarterectomy.

Objectives: Endarterectomy is the treatment of choice for arterial occlusive disease of the femoral bifurcation. Longitudinal arteriotomy and prosthetic patch angioplasty is the standard technique but, due to the increasing concerns with prosthetic-related infections and multidrug-resistant pathogens our group adopted an alternative approach. We present our experience with eversion femoral endarterectomy.

Surgical Treatment of Post-Carotid Endarterectomy Carotid Pseudoaneurysm.

Post-endarterectomy pseudoaneurysms (PEPA) are a rare complication of carotid endarterectomy (CEA), but are associated with high morbidity risk. Therefore, once they are diagnosed, treatment is urgent to prevent possible complications such as rupture, embolisation, thrombosis, or airway and cranial nerve compression. In this video, the surgical procedure is shown in a case of PEPA 10 years after CEA with patch angioplasty, which was successfully managed by surgical excision and interposition of great saphenous vein graft.
