Furthermore, we review the literature to increase awareness of this complication, its pathophysiology and therapeutic options. \u0000Results: Only rare cases of local perianeurysmal inflammation have been reported in literature. Clinical symptoms are heterogenous, up to focal seizures or symptoms of acute hydrozephalus. Pathophysiological, thrombembolism, local inflammatory and mass are possible aetiological factors. However, overall long-term prognosis is good. \u0000Conclusion: Neurovascular compression syndrome after intracraniel aneurysm coiling is a rare and possibly delayed complication.

Although the intermittent hypoxia has been suggested as a main cause of endothelial dysfunction in these subjects, the precise mechanism of this event is still unclear. The aim of this study was to demonstrate the correlation between the level of hypoxia during sleep with arterial blood pressure and plasma concentration of nitrite. Methods: Non-smoker subjects were included in a cross-sectional study. They underwent systolic and diastolic blood pressure (SBP and DBP) measured at bed before sleep and on walking up, overnight polysomnography (PSG), and measurement of nitrite in plasma from peripheral blood at walking up. Results: Sixty-five subjects with mean age of 58 ± 12 years were included in this study. The male-female ratio was 0.9 and BMI was 23.3 ± 3.4 kg/m2. The mean of systolic BP and diastolic BP post-PSG of subjects with SpO2<93% was significantly higher than subjects with SpO2 ≥ 93% (P<0.05 and P<0.01; respectively). The mean SpO2 and nadir SpO2 of subjects with SpO2<93% were significantly lower than subjects with SpO2 ≥ 93% (90 ± 4% vs. 94 ± 2% and 73 ± 9% vs. 88 ± 8%; P<0.05 and P<0.01; respectively). The level of apnea-hypopnea index in subjects with SpO2<93% was significantly higher than that in subjects with SpO2 ≥ 93% (P<0.01). The concentration of NO2- in peripheral blood of subjects with SpO2<93% was significantly lower than that in subjects with SpO2 ≥ 93% (P<0.01). There were the significant correlations between nadir SpO2 and NO2- with SBP and DBP on walking up. Conclusion: Endothelial dysfunction is a crucial event in subjects with OSA, especially for whom with obstructive sleep apnea. This event might be linked to the diurnal increase of peripheral blood pressure. The concentration of NO2- in plasma measuring on walking up might be a relevant marker of endothelial dysfunction during sleep.","PeriodicalId":17397,"journal":{"name":"Journal of Vascular Medicine & Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81684835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is to determine the effectiveness of embolization of each type of vascular malformation. Methods: A retrospective review was performed between January 2009 to June 2015 on 36 patients who were diagnosed vascular malformations in the head and neck regions and were referred to our department for transarterial or percutaneous embolization before the surgical approach. Results: All 26 AVM were embolized with a transarterial approach: 18 with Onyx, 8 with a combination of PVA and coils. All patients with an AVM had a single endovascular approach. All 10 venous-lymphatic malformations were treated with a percutaneous sclerotherapy with ethanol injection. Complete healing was obtained in 30 patients (83%). In 6 (17%) there was a recurrence with necessity of a retreatment, 4 at 6 months, 2 at 12 months. Conclusion: Transarterial embolization and percutaneous scleroterapy is a safe treatment for artero-venous malformations before the surgical treatment. A multidisciplinary approach is fundamental to reduce the bleeding risks, the time of the surgical intervention and favouring a lesser demolitive approach particularly in large vascular malformations. Surgical complications occurred in 6 patients (17%); all of them developed infections of the surgical wounds; 3 of these developed necrosis of the skin flap used for the reconstruction with subsequent dehiscence. No other complications including sepsis, hemorrhages, cranial nerve palsies or neuropathies occurred.","PeriodicalId":17397,"journal":{"name":"Journal of Vascular Medicine & Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81141741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
