In the endovascular management of intracranial aneurysms, the large use of the remodeling technique combined with stenting in selected cases enables a low rate of treatment failures without increasing the rate of complications.
ResultsThe research work was accomplished on the basis classification algorithms including training and test datsets along with well obtained characterized data. The classification process categorized the Alzheimer's disease in dataset and provides a better results. The feature relevance analysis displays the different important characteristics which are intended for better classification system. The random tree forms the classification rule to attain a zero error value.
ConclusionsThe experiment is projected to prove the efficiency of the presentation of numerous classifiers to the Alzheimer's disease and dataset used in it. This help the patient to treat at the right time.
Because neurointerventional surgery is a minimally invasive technique does not mean that it is qualified for complication-free procedures. Rather working about 2 m away from the three-dimensional (3D) target lesion and looking at two-dimensional (2D) images makes it one of the most complication-prone subspecialties. Advancement in hardwares, techniques, and technologies with continuous ability to learn and modify accordingly can only keep the complication rate low as compared with traditional vascular neurosurgery.
Flow diverter stents (FDS) are new neuroendovascular tools able to achieve the complete and curative treatment of aneurysm by reconstruction of the parent arteries from which the aneurysm arises. We present our initial experience with flow diverter embolization devices and follow-up results.Patients with large, giant and wide necked aneurysms, saccular, fusiform and recurrent aneurysms were selected for the treatment. All patients were pretreated with dual antiplatelet agents at least for 7 days before procedure and continued taking both agents for 3 months after treatment. A MRI was done after 3 months of treatment and digital subtraction angiogram was performed at 4 months of treatment. After 1 year both MRI and digital subtraction angiogram was performed.11 patients (age range 37 year to 79 year, mean 51.1) with 11 intracranial aneurysms were treated with 15 flow diverter stents. 9 aneurysm were located on the anterior circulation and 2 on posterior circulation. 8 aneurysms were large (10-25 mm), 2 were small (<10 mm) and 1 was giant (>25 mm) with mean largest diameter of 13.22 mm. 9 were saccular aneurysm and 2 were fusiform, out of these 3 were remnant of the previously treated aneurysm. Treatment was achieved with 10 Silk stents in 7 patients and 5 Pipeline embolization devices in 4 patients. The mean time between treatment and follow up was 9.6 months (range 4-12 months). One mortality was noted due to rebleed after 3 weeks of treatment. Complete angiographic occlusion was achieved in 9 (90%) patients after 4 months and 1 (10%) patient had near complete occlusion at 12 months. All the patients were stable clinically during follow up period.Endovascular treatment with FDS is safe, easy, and permanent treatment for the selected group of aneurysms. The complete occlusion rate in follow-up study approaches 100% with no angiographic recurrence in this study.
Endovascular therapy as any other specialty has continuously been developed since 1904, but acceptability among neurosurgeons remains low despite being other subspecialties and techniques, like endoscope and for that matter microscope also, being adopted very rapidly. From injecting particles for vascular lesions to balloons for fistulas and arteriovenous malformations and embolizing agents to detachable coils for aneurysm coiling, it has come a long way. Old generations of neurosurgeons used to perform carotid puncture for diagnosing mass lesions, but once CT/MRI came in to the picture, this procedure was stopped and handed over to radiologists. A debate continues among neurosurgeons about the feasibility of aneurysm coiling since international subarachnoid aneurysm trial (ISAT) and doubts about the long-term efficacy of this novel treatment cost a subspecialty. With the recent addition of endovascular treatment of stroke and long-term efficacy of endovascular treatment of aneurysm, there is a lot of debate among clinicians and nonclinicians about who will be the true heir of this sub specialty.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
