Complications of endovascular therapy for acute ischemic stroke and proposed management approach.
Over the past decade, endovascular therapy has emerged as a promising therapeutic approach for select patients with acute ischemic stroke. However, the morbidity, mortality, and complication rates in intra-arterial recanalization trials are higher than in the National Institute of Neurological Disorders and Stroke trial of IV tissue plasminogen activator. This review discusses common complications associated with endovascular therapy for acute ischemic stroke, avoidance of complications, and management of some of the common complications.

The initial treatment of patients with acute ischemic stroke (AIS) focuses on rapid recanalization, which often includes the use of endovascular therapies. Endovascular treatment depends upon micronavigation of catheters and devices into the cerebral vasculature, which is easier and safer with a motionless patient. Unfortunately, many stroke patients are unable to communicate and sufficiently cooperate with the procedure. ⋯ Currently, the choice between GA and conscious sedation should be tailored to the individual patient, on the basis of neurologic deficits, airway and hemodynamic status, and treatment plan. The use of institutional treatment protocols may best support efficient and effective care for AIS patients undergoing endovascular therapy. Important components of such protocols would include parameters to choose anesthetic modality, timeliness of induction, blood pressure goals, minimization of neuromuscular blockade, and planned extubation at the end of the procedure.

Endovascular therapy in the acute management of ischemic stroke has become more common with technologic advances, such as easier navigation into the intracranial circulation and improved treatment efficacy with the advent of revascularization devices. This select review outlines milestones in the application of endovascular therapy in acute ischemic stroke (AIS) and offers some insight into important factors influencing the future directions of endovascular AIS treatment. In particular, we discuss the evolution of endovascular devices for AIS and how ingenuity continues to offer novel treatments. With these advances, the future of endovascular AIS treatment is promising.

A large number of patients presenting with acute ischemic stroke have large artery intracranial occlusions, and timely recanalization of these occlusions often leads to improved neurologic outcome. Starting with the widespread use of IV tissue plasminogen activator, a wide variety of pharmacologic and mechanical methods have been introduced to improve vessel recanalization and clinical outcome of patients with acute ischemic stroke, which include endovascular therapies such as intra-arterial thrombolytics and mechanical thrombectomy devices. One of the potential therapies is angioplasty and stenting, and this has been evaluated in multiple case reports and small series published by various centers regarding its use in this setting. In this article, we review the current literature on stenting with and without angioplasty, used alone or as a part of multimodal therapy for recanalization for acute cerebrovascular occlusions.

Childhood periodic syndromes are thought to be early life expressions of the genetic tendency for migraine. The objective of this study was to determine whether maternal migraine is associated with an increased risk of infant colic, because this may indicate that colic is a childhood periodic syndrome. ⋯ Maternal migraine is associated with increased risk of infant colic. Because migraine has a strong genetic underpinning, this association suggests that colic may be an early life manifestation of migraine.
