In patients with chest pain, exercise stress test has a moderate accuracy for coronary artery disease (CAD). Adding a reliable cardiac biomarker to the exercise test could potentially improve the precision of the test. We investigated circulating NT-proBNP levels before and during exercise stress test in patients with and without angiographically verified CAD. Read More

Myocardial infarction (MI) is a prevalent cardiovascular disease defined by myocardial ischemia and hypoxic damage caused by plaque rupture, thrombosis, lumen stenosis, or blockage in the coronary artery. However, the development of emergency percutaneous coronary interventional therapy has enabled the rapid restoration of blood perfusion to ischemic myocardium and the rescue of dying myocardium cells. Some dying myocardium cells have caused irreversible damage and impaired cardiac function recovery in recent years. Read More

Renal allograft thrombosis is not a rare complication of kidney transplant and usually occurs in the early period after transplant, but it can also occur later after transplant. Several factors are associated with this infamous complication. The cause of venous anastomosis thrombosis is most often inflection or twisting of the renal vein, anastomosis stenosis, hypotension, hypercoagulation, or acute rejection of the graft. Read More

Background: Three-dimensional (3D) printing of mesenteric artery (MA) anatomy preprocedurally for endovascular interventions can allow strategic preprocedure planning and improve procedure-related clinical outcomes.

Methods: Three patients with computed tomography angiography (CTA) of the abdomen and pelvis who subsequently underwent MA interventions were 3D printed retrospectively, and 2 patients with symptoms and severe MA stenosis on CTA, who had not undergone intervention, were 3D printed for procedure-related planning and anatomy-specific implications. The 3D-printed models (3D-PMs) were painted with acrylic paint to highlight anatomy. Read More

Renal cell carcinoma (RCC) with inferior vena cava (IVC) and right atrium (RA) tumor thrombus (TT) is a rare occurrence and its resection is surgical challenge. Management becomes even more difficult when the TT causes hepatic vein obstruction and leads to Budd-Chiari syndrome. We report a case of 68-year-old male with right RCC with IVC and RA TT with associated Budd-Chiari syndrome. Read More

Background: IgG4-related disease (IgG4-RD) is an autoimmune condition affecting almost every organ system, with an early inflammatory phase and later fibrotic consequences. Vascular manifestations, particularly, large-vessel involvement in IgG4-RD, are well described.

Background And Objective: Renal artery stenosis (RAS) is associated with an increased risk of renal function deterioration (RFD). Our previous study showed that renal cortical blood perfusion assessed by contrast-enhanced ultrasound (CEUS) was an important related factor for RFD in RAS patients. Based on several conventional related factors confirmed by previous studies, we aimed to establish and verify a CEUS+ scoring system to evaluate the risk of RFD at 1 year of follow-up in RAS patients.

Introduction Superior mesenteric artery syndrome (SMAS), also called mesenteric duodenal compression syndrome, Wilkie's syndrome, chronic duodenal ileus or cast syndrome, is a rare clinical condition defined as a compression of the third portion of the duodenum in between the SMA and abdominal aorta (AA), due to narrowing of the space between them. SMAS is primarily attributed to loss of the intervening mesenteric fat pad, leading to partial or complete duodenal obstruction. Its manifestations are complex and non-specific, including postprandial epigastric pain, nausea, vomiting, early satiety, weight loss and anorexia. Read More

Fibromuscular dysplasia (FMD) is a potentially treatable cause of renovascular hypertension and it typically affects young females. FMD usually involves distal two-thirds of the renal artery and percutaneous transluminal renal angioplasty (PTRA) is the treatment of choice for FMD with resistant hypertension. PTRA is a safe procedure with minimal complications. Read More

Background: The objective is to investigate whether calculating the PPI (Pulse Pressure Index) and the RRI (Renal Resistive Index) using routinely collected Duplex ultrasound waveforms data obtained from the aorta and renal artery correlates and predicts renal function, and determine whether RRI is affected by the presence of a renal artery stenosis.

Methods: The records of 965 patients were evaluated. The RRI or pulsatility index of the aorta, renal artery, hilum, cortex, and medulla were measured with concurrent glomerular filtration rate GFR, Cr, PPI, and HR measurements, among which 75 patients had a 24-hour urine measured for CrCl, and 32 patients had aortic pulse pressure index (API) calculated from the central aortic pressure measured with applanation tonometry.

Purpose: To evaluate the remodeling of visceral arteries post-endovascular repair (TEVAR) of type B aortic dissection and to investigate interval change in renal volume and estimated glomerular filtration rate (eGFR) vis-a-vis baseline visceral artery morphology.

Materials And Methods: All patients of type B aortic dissection who underwent TEVAR with a baseline and follow-up CT during the study period were included. Baseline morphology of visceral arteries (celiac, superior, and inferior mesenteric artery and bilateral renal artery) were classified into 7 patterns depending upon the origin of the artery (from true/false lumen) and the extension of dissection flap, while occluded vessels were categorized as pattern 8.

Patients with type 2 diabetes mellitus (T2DM) constitute a large proportion of patients with atherosclerotic renal artery stenosis (ARAS). However, the mechanism of impaired renal function and hypertension in this subset of patients is multifactorial. We aimed to investigate whether, in diabetic patients, renal function (RF), systolic (SBP) and diastolic blood pressure (DBP) values following stent-supported angioplasty (PTA) for ARAS have an impact on cardiovascular and renal outcomes.

Background: Renal artery stenosis (RAS) is an important cause of chronic kidney disease and secondary hypertension. In animal models, renal ischemia leads to downregulation of growth-factor expression and loss of intrarenal microcirculation. However, little is known about the sequelae of large vessel occlusive disease on the microcirculation within human kidneys. Read More

Background: Arteriovenous fistula (AVF) is the preferred vascular access (VA) for hemodialysis, but it is still affected by high non-maturation and early failure rates due to stenosis development. Increasing evidence suggests that the presence of turbulent-like flow may play a key role, therefore, to stabilize the flow in the venous segment, an external support device (VasQ) has been designed. The aim of this study was to provide preliminary evidence of VasQ impact on AVF hemodynamics as compared to AVFs created with conventional surgery. Read More

The etiology of large artery aneurysms has long been established as secondary to atherosclerotic disease and degenerative changes in the vessel walls. Less common, are aneurysms of the visceral arteries; the splanchnic and renal arteries. Rarer yet, are inferior mesenteric artery aneurysms, accounting for approximately 1% of visceral artery aneurysms. Read More

Autologous arteriovenous fistula (AVF) is the primary and best option to obtain vascular access for hemodialysis treatment; other options are arteriovenous graft (AVG) and central venous catheterization (CVC). The implementation of radio-cephalic autologous arteriovenous fistula (RC-AVF) in the forearm was preferred among patients with superior vascular conditions. However, there is a high rate of early fistula failure. Read More

Introduction: and importance: Transplant renal artery stenosis (TRAS) is a well-recognized vascular complication after kidney transplant that can lead to graft loss, when it is diagnosed early and treated appropriately it may prevent kidney damage and related systemic squeals.

Case Presentation: This case-series represents our center experience in managing TRAS using percutaneous transluminal angioplasty [either balloon angioplasty (PTA) or stent placement (PTAS)] in 11 patients.

Clinical Discussion: All treated patients experienced immediate total recovery of renal function and normalization of arterial blood pressure without any drug or reducing the number of drugs used; no complications related to the intervention were reported. Read More
