The Guglielmi Detachable Coil introduced by the Boston Scientific Corporation has been widely used for endovascular coiling of aneurysm. Recently, Sapphire platinum detachable coils (eV3, Irvine, CA) have been introduced for aneurysm coiling. Herein, we report our clinical experience with the Sapphire coil to evaluate the incidence of coil related complications and the rate of aneurysm occlusion. ⋯ The Sapphire coil could safely be used in the treatment of both ruptured and unruptured aneurysms. However, multi-diameter non-stretch resistant coils may be associated with coil stretching when used in conjunction with a stent. Further study is still required for definitive results.

Hypotension is common following carotid artery stenting (CAS), and may be mediated by vagal stimulation and/or suppression of spinal sympathetic outflow. Both mixed alpha/beta agonists (dopamine (DA)), and more selective alpha- agonists (norepinephrine (NE) and phenylephrine (PE)), have been used, but the most effective treatment of post-CAS hypotension is unknown. ⋯ Compared with DA, treatment of post-CAS hypotension with a selective alpha-agonist (NE or PE) is associated with shorter drug infusion time, shorter CCU LOS, and fewer major adverse events.

Status epilepticus (SE) is a medical emergency requiring prompt treatment to try to limit mortality and improve outcome. So far, newer antiepileptic drugs (AED) have not assumed a noticeable role in the treatment of SE. This may be in part due to the lack of IV forms for the newer AEDs. The IV form of Levetiracetam (IV-LEV) has recently become available and has a potential role in the treatment of SE. ⋯ IV-LEV may have a potential role in the treatment of non-convulsive status epileptics.

Case Reports
Aminophylline for the treatment of symptomatic bradycardia and asystole secondary to cervical spine injury.
Bradycardia is a common complication of cervical spine damage in the weeks following injury, occurring in up to 100% of patients in some studies. Cardiac arrest and asystole have been reported in as many as 15% of these patients and cardiac events are the main cause of death within the first year. We describe the case of a 25-year-old African-American male involved in a motor vehicle collision who suffered C6-C7 subluxation. ⋯ There is limited evidence for the use of methylxanthines in the treatment of bradycardia associated with spinal cord injury. In patients with recurrent asystolic events or symptomatic bradycardia the use of these agents should be considered.
