Background Among asymptomatic patients with severe carotid artery stenosis but no recent stroke or transient cerebral ischaemia, either carotid artery stenting (CAS) or carotid endarterectomy (CEA) can restore patency and reduce long-term stroke risks. However, from recent national registry data, each option causes about 1% procedural risk of disabling stroke or death. Comparison of their long-term protective effects requires large-scale randomised evidence.Methods ACST-2 is an international multicentre randomised trial of CAS versus CEA among asymptomatic patients with severe stenosis thought to require intervention, interpreted with all other relevant trials. Patients were eligible if they had severe unilateral or bilateral carotid artery stenosis and both doctor and patient agreed that a carotid procedure should be undertaken, but they were substantially uncertain which one to choose. Patients were randomly allocated to CAS or CEA and followed up at 1 month and then annually, for a mean 5 years. Procedural events were those within 30 days of the intervention. Intention-to-treat analyses are provided. Analyses including procedural hazards use tabular methods. Analyses and meta-analyses of non-procedural strokes use Kaplan-Meier and log-rank methods. The trial is registered with the ISRCTN registry, ISRCTN21144362.

Residual vein thrombosis (RVT) indicates

No abstract

Outpatient treatment of deep vein thrombosis (DVT) has become a common practice in uncomplicated patients. Few data are still present in patients with comorbidity (such as cancer) or concomitant symptomatic pulmonary embolism. Cancer patients with DVT are often excluded from home treatment because they have a higher risk of both bleeding and recurrent DVT. We tested the feasibility and safety of the Home Treatment (HT) program for acute DVT a PE in cancer patients. Patients were treated as outpatients unless they required admission for other medical problems, were actively bleeding or had pain that requires parenteral narcotics. Outpatient treatment was with low molecular weight heparin (LMWH) followed by warfarin or with LMWH alone. An educational program for patients was implemented. Two-hundred and seven patients with cancer were evaluated, 36 (17.4%) of whom had metastatic disease. Treatment with LMWH and warfarin was prescribed to 106 (51.2%) and LMWH alone to 102 (48.8%). One hundred and twenty-seven patients (61.3%) were entirely treated at home. There were no differences between patients treated at home and hospitalized patients with regard to gender, mean age, site of cancer, presence of metastases, and treatment. After 6 months, recurrent thrombo-embolism occurred in 8.7% of patients treated at home and in 5.6% of hospitalized patients (P=0.58); major bleeding in 2.0% and 1.5%, respectively (P=0.06). Twenty-seven patients (33%) in the hospitalized, and 33 (26%) in the home-treatment group, died after a follow-up of 6 months. These results indicate that, regarding cancer patients with acute DVT and/or PE, there is no difference between hospitalised and home-treated patients in terms of major outcomes.

Brachial artery aneurysm (BAA) following long-standing arteriovenous fistula ligation after renal transplantation is uncommon. Herein, we describe the case of a 64-year-old man who developed a giant symptomatic BAA 21 years after ligation of the fistula. He was submitted to surgical excision of the aneurysm followed by interposition prosthetic graft.
