ess the relationship between umbilical cord blood gases at birth and morphology of umbilical cord, in a prospective study of 200 consecutive term delivery, we investigated the relationship between umbilical cord morphology characteristics (umbilical crd length, number of vascular coil, coiling index) and color of amniotic fluid and umbilical vessel blood gases. statistically significant linear ...

BACKGROUND AND PURPOSE Stent-assisted coiling and balloon-assisted coiling are 2 well-established techniques for treatment of wide-neck intracranial aneurysms. A direct comparative analysis of angiographic outcomes with the 2 techniques has not been available. We compare the angiographic outcomes of wide-neck aneurysms treated with stent-assisted coiling versus balloon-assisted coiling. MATER...

BACKGROUND AND PURPOSE Some cerebral aneurysms that have been coiled reopen over time and additional treatment should be considered to reduce the risk of recurrent hemorrhage. Our purpose was to assess procedural complications and angiographic results of additional coiling in patients with previously coiled but reopened aneurysms and to evaluate protection against (re)bleeding. METHODS We com...

This paper proposes the eccentric problem in the coiling process of cold rolling mills. The wavelets multiresolution control method is designed: A wavelets multi-resolution controller is introduced in the control cycle of coiling tension control, whose purpose is to acquire the element caused by periodically change of the coiling eccentricity. Then the signal without effectiveness of the coilin...

BACKGROUND AND PURPOSE Antiplatelets are frequently used during or after endovascular coiling of aneurysm in patients with subarachnoid hemorrhage (SAH). This strategy is based on uncontrolled case series including also patients with unruptured aneurysms or other lesions. We collected data on effectiveness of antiplatelets in patients with SAH. METHODS All 43 participating centers in the Inte...

The mechanisms involved in coiling phagocytosis are not yet known, and it is not even clear whether this phenomenon is either an incidental event or a specific response. Therefore, the phagocytic uptake of Borrelia burgdorferi and other spirochetes by human monocytes in vitro was used to investigate the involvement of both sides--microbes and phagocytes--in coiling phagocytosis. As seen with el...

The microstructure, mechanical properties, and hydrogen permeation behavior of hot rolled enamel steel were investigated. Three coiling temperatures were adopted to gain different sizes of ferrite grain and TiC precipitates. The results show that a large number of interphase precipitates of nano-sized TiC can be obtained at coiling temperatures of 650 and 700 °C, while a few precipitates are fo...

BACKGROUND AND PURPOSE There is no satisfactory parameter that can predict the need for assistant devices for endovascular aneurysm coiling. Our aim was to evaluate the utility of MOA as a predictor of the need for stent-assisted coiling in ICA sidewall aneurysms. MATERIALS AND METHODS From a retrospective review of an internal data base, 55 consecutive ICA sidewall aneurysms were identified....

background: management of intracranial aneurysms has made debates about the best treatment modality in recent years. the aim of this study was to compare the interventional outcomes between two groups of patients, one treated with endovascular coiling and the other treated with surgical clipping. methods: this prospective study included 48 patients with intracranial aneurysms who underwent endo...

Internal carotid-posterior communicating artery (IC-PC) aneurysms account for more than 20% of all intracranial aneurysms. As a result of the increase in coiling, there has also been an increase in recurrent IC-PC aneurysms after coiling. We present our experience of 10 recurrent IC-PC aneurysms after coiling that were retreated using surgical or endovascular techniques in order to discuss the ...
