Highlights ■ The calcium score can be calculated using computed tomography angiography. ■ The aortic calcium score was associated with amputation and subsequent revascularization within 30 days. ■ The calcium score in below-the-knee arteries was higher in the patients who underwent subsequent revascularization and amputation at 12 months. ABSTRACT Objective: To evaluate the association between lower limb artery calcium scores in preoperative computed tomography angiography and outcomes of patients with critical limb ischemia who underwent revascularization procedures in the aortoiliac […]

Highlights ■ The learning curves for robotic peripheral arterial interventions were short, with optimal procedure and fluoroscopy times and radiation emission achieved after the 3rd procedure. ■ There were no differences in learning curves in relation to previous experience or main focus of work. ABSTRACT Objective: This study tests a suitable model for training robot-assisted peripheral vascular interventions and examines the learning curves of endovascular surgeons with different levels of previous experience and main focus of work, analyzing procedure time, […]

ABSTRACT A 42-year-old female patient with a surgical history of iliac venous angioplasty with stenting developed dyspnea on exertion 9 months later. Chest computed tomography angiography revealed a fractured vascular stent in the right cardiac chamber. Doppler echocardiography confirmed that the stent was anchored by the tricuspid valve, causing mild obstruction of the right ventricular filling. The patient underwent robot-assisted cardiac surgery with stent removal, annuloplasty under general anesthesia, and cardiopulmonary bypass via an axillary incision. No sternotomy, cardioplegia, or […]

ABSTRACT Spontaneous renal artery dissection is an unusual and idiopathic condition in most cases. In young, mildly symptomatic patients, diagnosis may be difficult, frequently culminating in delay in treatment. This report presents the case of a 40-year-old male patient, with severe hypertension of sudden onset, and difficult management of oral medication. In etiological investigation, Echo-Doppler of renal arteries showed signs of hemodynamically relevant right renal artery stenosis. Arteriography showed presence of double-lumen and thrombus in the vessel lumen, indicating dissection. […]

ABSTRACT Sophisticated imaging systems have helped to redefine the clinical presentation of acute macular neuroretinopathy and have markedly enhanced diagnostic sensitivity. The proposed mechanism of paracentral acute middle maculopathy is related to ischemia at the level of the superficial and deep retinal capillary plexi. This is a case report of a patient who developed an acute macular neuroretinopathy after an uneventful angioplasty with stents in the coronary artery.

ABSTRACT Objective To analyze the results of ten angioplasties of TASC C and D femoropopliteal lesions using CO2 as primary contrast in patients with no formal contraindication to iodine, aiming to decrease allergic reactions and potential nephrotoxicity in high-risk patients. Methods We describe the results of ten angioplasties of TASC C and D femoropopliteal lesions using CO2 as primary contrast in patients with high risk for open revascularization and no formal contraindication to iodine. We analyzed feasibility of the procedures, […]
