ABSTRACT
Introduction:Massive intracerebral hemorrhages and large internal carotid artery infarcts may cause early death due to severe cerebral edema with elevated intracranial pressure, despite maximal medical therapy. Decompressive craniectomy may be of benefit to these patients in terms of survival and even functional outcome. The aim of our paper is to present two cases that illustrate the use of decompressive craniectomy both in ischemic and hemorrhagic stroke, followed by a discussion on the indication and right timing of the intervention, but also on the outcome of these patients. Materials and methods: We present the cases of a 38-year-old man with a right lenticular and capsular hemorrhage who underwent decompressive craniectomy in the first 24 hours from onset of symptoms and a 64-year-old patient with an ischemic stroke in the territory of the left carotid artery with a decompressive craniectomy performed at more than 72 hours from the beginning. For each of the two cases, we analyzed the following parameters: neurologic status, Glasgow Coma Scale, aspect of the cerebral computed tomography before and after surgery, in-hospital complications and modified Rankin Scale at discharge. Outcomes: While the intervention was life-saving in both cases, the procedure had different functional outcomes. Conclusion: Decompressive craniectomy may be a life-saving procedure for patients with both hemorrhagic or ischemic strokes complicated with massive edema and increased intracranial pressure. When performed in the first 48 hours, especially in patients with ischemic stroke aged less than 60, it may also improve the functional outcome compared to conservative treatment.
ABSTRACT
Giant intracranial aneurysms (ICGA) represent 3 to 5% of all intracranial aneurysms in adults. They are defined as arterial dilatations, with more than 25 mm in diameter. Despite important advances in the research of endovascular techniques of treating giant intracranial aneurysms, the management of these vascular malformations still poses great difficulties for neurologists and interventional radiologists. In particular, these challenges arise from the difficult and modified cerebral anatomy of patients with ICGA. Choosing the best treatment for patients with ICGA involves not only finding the perfect balance between the potential risks and benefits of endovascular treatment, but also taking into consideration the patient's biological condition and associated diseases. The aim of this paper is to describe the decisional algorithm of treating patients with giant intracranial aneurysms and factors which could influence the choice of endovascular technique. We report a clinical case of a 63-year-old female with cardio-vascular risk factors (atrial fibrillation, high blood pressure), diagnosed with a symptomatic giant aneurysm of the right internal carotid artery and multiple cerebral micro-bleeds. Given the very large size of the aneurysm, its characteristics as well as patient's associated comorbidities, it was decided to exclude the ICA aneurysm from circulation by occluding the parent vessel (right internal carotid artery) by using endovascular techniques. Also, a review of the literature on the currently available endovascular methods for treating patients with giant intracranial aneurysms was performed in order to see the indications and possible long-term complications of each method. In selected cases, the risks of serious complications associated with occluding a large cervical-cerebral vessel (as the internal carotid artery) are far exceeded by the risk for rupture of giant aneurysms, which is fatal in many cases. Nevertheless, it is of utmost importance to mention that, although the use of endovascular methods leads to a significant increase in life expectancy, a severe decline in quality of life might be experienced by these patients.
