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.

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.

Stent-graft repair for blunt traumatic aortic injury: functional and survival outcomes.

Aim: Traumatic aortic injury is usually lethal, most often because of serious associated wounds. The short- and midterm outcome of endovascular exclusion was assessed as the current treatment of choice due to a lower mortality and morbidity than open surgical treatment.

Methods: We reviewed the cases of 8 patients (5 male, mean age 33 years) undergoing endovascular repair of a traumatic thoracic aortic lesion, confirmed by computed tomographic angiography, at our centre.

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.

[Contralateral occlusion: does it affect the therapeutic management of carotid stenosis?].

Introduction: Because the contralateral carotid artery occlusion has been considered a high risk factor for ipsilateral carotid endarterectomy, some authors indicate a stenting procedure in these cases.

Aim: To evaluate whether there are different preoperative factors in patients with contralateral carotid occlusion and if the latter is associated to worse perioperative outcome.

Patients And Methods: We analysed 476 carotid endarterectomies performed in 1994-2004.

[Immediate and long-term outcomes of carotid endarterectomies in eighty-year-olds].

Aims: To compare the immediate results obtained after performing a carotid endarterectomy (cEDA) in patients in their eighties with those of younger patients, and to determine survival and stroke-free times following carotid surgery in the two groups.

Patients And Methods: Retrospective data was collected regarding a series of 319 cases of cEDA (302 patients) performed between January 1998 and December 2004. Group 1: patients aged 80 or above.

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.

Surgery for aortoiliac aneurysm after kidney transplant.

Objective: Although aortoiliac aneurysm in kidney transplant patients is uncommon, aortic clamping during the surgical repair of an aneurysm could pose a risk to the grafted kidney and might also increase the risk of vascular prosthesis infection due to immunosuppression. Herein, we present our results related to the treatment of the aortoiliac aneurysm subsequent to kidney transplant.

Material And Methods: Four male kidney transplant recipients underwent surgery for aortoiliac aneurysm repair.
