Introduction The role of carotid shunting in carotid endarterectomy is controversial. Many studies have concluded that patch angioplasty is preferable to primary closure, while others found that it had no value. The aim of this study was to report the results of our first series of patients undergoing carotid endarterectomy with a non-shunting technique and primary closure of the arteriotomy. Methods From October 2014 to October 2017, 63 patients with unilateral or bilateral carotid artery stenosis underwent carotid endarterectomy...

A 74-year old man presented recurrent angina pectoris due to in-stent restenosis (ISR) with severely calcified neointima. In-stent neoatherosclerosis (NA) is associated with late stent failure, and NA with calcified neointima occurs in some cases. Because the presence of neointimal calcification could lead to underexpansion of newly implanted stent for ISR, a scoring balloon was selected for predilatation to obtain maximum extrusion of the neointimal plaque and subsequently, an everolimus-eluting stent was implanted...

BACKGROUND: Diabetic foot ulcer (DFU) is a severe complication of diabetes, preceding most diabetes-related amputations. DFUs require over US$9 billion for yearly treatment and are now a global public health issue. DFU occurs in the setting of ischemia, infection, neuropathy, and metabolic disorders that result in poor wound healing and poor treatment options. Recently, stem cell therapy has emerged as a new interventional strategy to treat DFU and appears to be safe and effective in both preclinical and clinical trials...

We analyze the changes in upper and lower limb pulse transit times (PTT) caused by peripheral artery disease (PAD) and its treatment with percutaneous transluminal angioplasty (PTA) of the superficial femoral artery. PTTs were extracted from the photoplethysmograms (PPG) recorded from an index finger and 2nd toes. PTTs were defined between the R-peaks of the ECG and different reference points of the (PPG): foot and peak points, maxima of 1st and 2nd derivative, and by means of intersecting tangents method. Also the PTTs between the toe and finger pulses were analyzed...

INTRODUCTION: Atherosclerotic intracranial artery stenosis (ICAS) is one of most common causes of stroke, which is the second-leading cause of death worldwide. Medical, surgical and endovascular therapy are three major treatments for ICAS. Currently, medical therapy is considered as the standard of care for most patients with ICAS, while extracranial to intracranial bypass is only used in rare situations. Balloon angioplasty alone, balloon-mounted stent and self-expanding stent, collectively called endovascular treatment, have shown promising potentials in treating specific subgroups of patients with symptomatic ICAS; however, their comparative safety and efficacy is still unclear...

Robotic-assisted coronary angioplasty has been utilized to decrease radiation exposure to cardiologists, and to diminish risk of orthopedic and ergonomic injuries caused by wearing heavy lead during long procedures. The efficacy and safety of robotic-assisted percutaneous coronary intervention for relatively low-risk lesions was demonstrated in the PRECISE study. Successful percutaneous coronary interventions using robotic system for treatment of complex high-risk lesions have been reported in few case series so far...

Introduction: Inferior vena cava agenesis (IVCA) is one of the many anomalies of this vessel. It is one of the most uncommon anomalies, with an estimated prevalence of 0.0005-1% in the general population. Around 5% of the patients younger than 30 years with a diagnosis of deep vein thrombosis (DVT) have a total or segmental IVCA. Report: Here two unique cases of young and previously healthy male patients are reported: one with bilateral lower extremity DVT, the second with lower extremity DVT and pulmonary embolism...

Spontaneous coronary artery dissection (SCAD) is a common cause of acute coronary syndrome particularly in younger women. Good outcomes with conservative management are generally expected. However, there is uncertainty of how to manage symptomatic or unstable patients. Percutaneous angioplasty may propagate the subintimal hematoma compromising coronary blood flow. Cutting balloon angioplasty can relieve the compressive effects of a propagated subintimal hematoma in SCAD.

BACKGROUND: Diagnostic and Interventional Nephrology has been a rising field in recent years worldwide. Catheter insertion, renal biopsy, renal ultrasound, and peritoneal dialysis catheter or permanent dialysis catheter insertion are vital to our specialty. At present, many of these procedures are delegated to other specialties, generating long waiting lists and limiting diagnosis and treatment. METHODS: An online survey was emailed to all Nephrology departments in Spain...

Balloon angioplasty can cause shear stress and tear of the vascular endothelium during mechanical dilatation, leading to increased inflammation and coagulation reactions of the vascular endothelium. Herein, a worst case of active rheumatoid vasculitis is described, where due to progressing ischemic necrosis of the leg, endovascular intervention was unavoidably performed in the presence of active rheumatoid vasculitis. After percutaneous balloon angioplasty, the patient developed recurrent thrombotic occlusion of the leg arteries, and finally, limb amputation resulted in despite vigorous treatment including medication, immunosuppression, catheter-directed thrombolysis, and post-thrombolysis anticoagulation...

The objective of this case report is to alert the cardiologists and radiologists about the possibility of an extremely rare trifurcation of the right coronary artery. During dissection classes, an early trifurcation of the right coronary artery (RCA) was observed in an adult male cadaver aged approximately 65 years. The RCA had a normal origin from the anterior aortic sinus. After a course of just 2 mm, it trifurcated into a conus artery, a huge right ventricular branch and then a main continuation of the RCA...
