Results of endovascular treatment of venous anastomotic stenosis in prosthetic arteriovenous for hemodialysis PTFE grafts. Comparative analysis between patent and occluded grafts.

Objective: To analyze the results of endovascular treatment of venous anastomotic stenosis (VAS) in humero-axillary arteriovenous grafts (HAG), comparing outcomes between patent and thrombosed HAG.

Material And Methods: A retrospective cohort study was made of endovascular treated patients because of a VAS in a HAG between January 2009 and December 2019. Group A: Thrombosed HAG secondary to a VAS.

Aortic Rupture by an Acute Dissection of the Thoracoabdominal Aorta in a 12-Year-Old Boy.

Aortic dissection is exceptional in children. When they are affected, many clinical conditions as Marfan syndrome or Ehlers-Danlos syndrome are usually involved, but up to 22% have no associated background. Its high morbidity and low incidence in this age group require a high level of suspicion in children without predisposing factors when the presentation is atypical, to avoid the severe consequences of the delay of their diagnosis.

Comparison of popliteal artery aneurysm therapies.

Objective: Surgical treatment of popliteal artery aneurysms (PAAs) has advanced over time. Constant development of new endovascular techniques has converted these into the most attractive methods available today. However, results for each endovascular procedure are still limited, and available data have emerged from studies examining only a small number of cases.

Treatment with amlodipine and atorvastatin has additive effect on blood and plaque inflammation in hypertensive patients with carotid atherosclerosis.

Since previous studies have reported a beneficial effect of amlodipine and atorvastatin treatment in experimental atherosclerosis, we aimed to investigate the effect of the combination of both drugs on blood and plaque inflammation in patients with carotid stenosis. For that purpose, twenty six hypertensive patients undergoing carotid endarterectomy were randomized to receive either atorvastatin 20 mg/day alone (ATV, n=12) or in combination with amlodipine 20 mg/day (ATV+AML, n=14) before scheduled carotid endarterectomy. At the end of follow-up (4-6 weeks), there was a significant decrease in total and LDL-cholesterol levels, but not in blood pressure levels.

[Peripheral artery disease: pathophysiology, diagnosis and treatment].

Peripheral artery disease is one of the most prevalent conditions, and it frequently coexists with vascular disease in other parts of the body. Early diagnosis is important for improving the patient's quality of life and for reducing the risk of serious secondary vascular events such as acute myocardial infraction (AMI) or stroke. The best noninvasive measure for identifying the presence of occlusive arterial disease is the ankle-brachial index, which can also be used to indicate the prognosis of the affected extremity and to predict the likelihood of AMI during follow-up.

Disease progression in the contralateral carotid artery after endarterectomy.

Our objectives were to establish the incidence and progression of stenotic lesions in the contralateral carotid artery (CCA) after endarterectomy, to identify subpopulations of patients at risk of contralateral disease progression, and to evaluate the efficacy of duplex scanning surveillance at detecting these lesions. We performed a prospective study on 180 patients in whom the CCA to the operated artery was healthy or showed <70% stenosis. All patients had completed a clinical and hemodynamic follow-up program, including duplex scanning of both carotids, with sessions 3 and 6 months after surgery and then every semester until 2 years.
