A reconstruction strategy of stent-assisted coiling was planned. INCLUDE WHEN CITING Published online April 22, 2016; DOI: 10.3171/2016.1.JNS152447. Case 50. Posterior circulation DMVOs were located in the P2 segment of the PCA in 149 patients (81.0%) and in the P3 segment in 35 patients (19.0%). Follow-up angiograms showed that recanalization occurred only in 1 of 18 patients (5.6%) with a partially thrombosed aneurysm that received retreatment. Considering that immediate complete occlusion of a fetal-type aneurysm and its parent artery may cause serious ischemic complications, the aneurysm was partially occluded together with the parent artery. For fusiform/dissecting aneurysms of the proximal PCA or with a fetal-type PCA, partial coiling of the aneurysm and parent artery is an attractive alternative treatment with good clinical and anatomical outcomes. The endovascular modalities included the following: 1) selective occlusion of the aneurysm (n = 22); 2) complete occlusion of the aneurysm and the parent artery (n = 20); 3) parent artery occlusion (n = 6); 4) partial coiling of the aneurysm and the parent artery (n = 5); and 5) occlusion of the dissecting aneurysm sac (n = 2). *Two patients, including 1 patient with a saccular aneurysm and 1 patient with a dissecting aneurysm, were lost to follow-up. AJNR Am J Neuroradiol 23:1128–1136, 2002, Hamada J, Morioka M, Yano S, Todaka T, Kai Y, Kuratsu J: Clinical features of aneurysms of the posterior cerebral artery: a 15-year experience with 21 cases. Angiography performed at 16 months showed complete occlusion of the aneurysm and parent artery. Four of the 55 patients had multiple PCA aneurysms on the same side, 2 patients had 2 saccular aneurysms, and 2 patients had 2 fusiform aneurysms. The parent artery was occluded very proximal to the aneurysm. J Neurointerv Surg 6:595–599, 2014, Lv X, Li Y, Jiang C, Yang X, Wu Z: Parent vessel occlusion for P2 dissecting aneurysms of the posterior cerebral artery. Of 243 patients from all participating centers who met the inclusion criteria, 184 patients were matched. In the present study, we retrospectively reviewed our experiences with endovascular treatment in a series of 55 patients with 59 PCA aneurysms. However, due to limited experience with this technique, the overall risk of complications, including hemorrhage and infarction, is increased. In the present study, 29 (85.3%) of 34 fusiform/dissecting aneurysms were located on the P2 or distal segments. H: Follow-up angiogram obtained 16 months later showing complete occlusion of the aneurysm and parent artery. We examine what to look for and possible treatments available to regain a normal life after an attack. The most frequent location for PCA aneurysms reported elsewhere is the proximal segment, including P1 and the P1/P2 junction.13,16 Goehre et al.16 reported that the proximal PCA harbored 69% of all PCA aneurysms. 3). In our present study, 1 patient with a P1 fusiform aneurysm was treated with stent-assisted coiling. Theoretically, bypass would decrease the number of patients experiencing visual deficits. Identify all potential conflicts of interest that might be relevant to your comment. The treatment strategy depends on the type of the aneurysm (e.g., saccular, dissecting, or fusiform).17 For smaller saccular PCA aneurysms, it may be possible to perform direct clipping without great technique difficulty or significant procedure-related morbidity.22 Since PCA aneurysms are more likely to be large and fusiform, direct clipping is usually impossible. These patients received mechanical thrombectomy or standard medical treatment (with or without IVT) at 1 of 23 comprehensive stroke centers in Europe, the United States, and Asia between January 1, 2010, and June 30, 2020. Anterior and posterior circulations provide the primary blood circulation of the brain. HH = Hunt and Hess grade; NA = not available; PA = parent artery. The aneurysm was nearly completely occluded with minimal filling of the distal PCA. All Rights Reserved, Published online February 22, 2021. doi:10.1001/jamaneurol.2021.0001. Acta Neurochir (Wien) 153:2151–2158, 2011, Kocaeli H, Chaalala C, Abruzzo TA, Zuccarello M: Results of surgical management for posterior cerebral artery aneurysms: 7-year experience in the endovascular era. Further studies and larger case series are necessary to assess the efficacy and durability of this treatment. Roh et al.29 reviewed the literature and analyzed 72 patients who were treated with the endovascular approach. Twenty-two patients (96%) were independent with a GOS score of 4 to 5 at discharge; the remaining patient died 2 weeks after occlusion of the aneurysm due to severe clinical status (Hunt and Hess Grade V SAH). Clinical outcomes were excellent (Glasgow Outcome Scale 5) in 47 of 49 patients at the long-term follow-up. Follow-up angiograms showed that recanalization occurred in 2 (10%) of 20 patients. Mechanical thrombectomy or standard medical treatment with or without IVT. Methods: All consecutive PCA strokes registered in the Athens Stroke Outcome Project between 01/1998 and 12/2009 were included in the analysis. Within minutes, brain cells begin to die.A stroke is a medical emergency. The aneurysm was embolized with detachable coils (Guglielmi Detachable Coils, Stryker; Microplex, Microvention; NXT fiber coils, Covidien).24 Patients who underwent stent-assisted coiling were given antiplatelet agents (75 mg/day clopidogrel and 300 mg/day aspirin) for 3 days before the procedure. Lv et al.25 reported a series of 8 patients with P2 dissecting aneurysms treated by parent vessel occlusion. It's also referred to as brain ischemia and cerebral ischemia. The other 30 patients (94%) were independent with GOS scores of 4 to 5 at discharge (Table 5). Visual field examinations. Case 38. The entire dissected lesion was too long, and the endovascular occlusion mainly covered the proximal affected lesion. All patients who met the inclusion criteria were matched using 1:1 propensity score matching.

Long-term management of all types of stroke focuses on the management of modifiable risk factors (i.e., hypertension and atherosclerosis). Clinical end point was the improvement of National Institutes of Health Stroke Scale (NIHSS) scores at discharge from baseline. AJNR Am J Neuroradiol 27:1685–1692, 2006, Brinjikji W, Murad MH, Lanzino G, Cloft HJ, Kallmes DF: Endovascular treatment of intracranial aneurysms with flow diverters: a meta-analysis. Functional outcome was evaluated with the modified Rankin Scale (mRS) score at 90-day follow-up. A 59-year-old woman had a cerebral aneurysm that was incidentally discovered during a medical examination. First, insufficient initial packing might contribute to coil compaction and recanalization.3 When possible, we occluded the smallest length of the parent artery with coils. They also showed that significant risk increases when bypass is combined with a subsequent endovascular procedure. A 44-year-old woman was admitted to our hospital with a 1-month history of dizziness. 2). According to the National Institute of Neurological Disorders and Stroke, Wallenberg Syndrome (aka Lateral Medullary Syndrome or Posterior Inferior Cerebellar Artery Syndrome) is a neurological condition caused by a blockage of the vertebral artery (VA) or posterior inferior cerebellar artery (PICA), ultimately leading to infarction of the lateral medulla . (See Anatomy, Pathophysiology, Etiology, Treatment, and Medication.) None of the patients experienced visual deficits or any other complications. The patient suffered headache, but had no postoperative neurological deficit (Table 4). Thirty aneurysms (50.8%) were small (< 1.0 cm), 21 (35.6%) were large (≥ 1 cm and ≤ 2.5 cm), and 8 (13.6%) were giant (> 2.5 cm). These findings coincide with the results reported by Hamada et al.18 and Ferrante at al.15 They found that the P2 segment was the most common location for PCA aneurysms. 22 Since PCA aneurysms are more likely to be large and fusiform, direct clipping is usually impossible. Because posterior cortical atrophy resembles Alzheimer’s disease in some patients, it has been suggested that drugs used to temporarily alleviate brain dysfunction in Alzheimer’s disease may be helpful in posterior cortical atrophy, but this is not proven. Discover the symptoms, causes, and risk factors of ischemic stroke. J Neurosurg 48:534–559, 1978. Five moderately disabled patients (GOS Score 4) improved to good recovery (GOS Score 5), whereas 2 other patients with GOS Score 4 remained stable. Speech therapy usually is not required for patients who have had a PCA stroke. To investigate the frequency as well as the clinical and safety outcomes of mechanical thrombectomy for isolated posterior circulation DMVO stroke and to compare them with the outcomes of standard medical treatment with or without intravenous thrombolysis (IVT) in daily clinical practice. The final results included 23 complete occlusions (88%) and 3 incomplete occlusions (12%). Treatment is largely determined by the amount of time that has passed since the start of the stroke. E and F: Thirteen-month follow-up angiograms in anteroposterior (E) and oblique (F) views showing complete obliteration of the aneurysm. A CT scan showed a round high-density lesion in the left ambient cistern. Additionally, it is sometimes difficult to occlude the entire dissected lesion. One patient (Case 45), who had multiple fusiform aneurysms, was treated by occlusion of only the proximal aneurysm together with the parent artery. Between January 2007 and December 2014, 3508 aneurysms were treated at our institution. D: Left internal carotid angiogram revealing the patency of left posterior communicating artery (arrow) and retrograde filling of the aneurysm via the P1 segment. Symptoms from posterior cerebral artery (PCA) stenosis are uncommon and are usually secondary to ischemia of the distal territory of the vessel and include visual and sensory disturbances. In the remaining patient (Case 4) with a large saccular aneurysm, the coils protruded into the parent artery during embolization. to download free article PDFs, 1. Right internal carotid angiography demonstrated collateral filling of the PCA segments distal to the occlusion. Identifying mechanisms of stroke is essential so that appropriate preventive therapies may be instituted. Between January 2007 and December 2014, 55 patients with 59 PCA aneurysms were treated using the endovascular approach at the authors' institution. Get free access to newly published articles. The authors report no conflict of interest concerning the materials or methods used in this study or the findings specified in this paper. Compared with intracranial aneurysms that occur at other anatomical locations, PCA aneurysms have some unique morphological characteristics and a number of specific clinical findings.29 According to previous studies, PCA aneurysms are more likely to affect young patients.15 However, the average patient age of 47.5 years in our series was not significantly younger than the average age (range 50–60 years) of patients with aneurysms at other anatomical sites. Aneurysms of the posterior cerebral artery (PCA) are uncommon. For fusiform/dissecting aneurysms of the distal PCA, occlusion of the aneurysm together with the parent artery is safe and effective. At discharge, the mean NIHSS score decrease was −2.4 points (95% CI, −3.2 to −1.6) in the standard medical treatment cohort and −3.9 points (95% CI, −5.4 to −2.5) in the mechanical thrombectomy cohort, with a mean difference of −1.5 points (95% CI, 3.2 to −0.8; This study suggested that, although rarely performed at comprehensive stroke centers, mechanical thrombectomy for posterior circulation DMVO is a safe, and technically feasible treatment option for occlusions of the P2 or P3 segment of the PCA compared with standard medical treatment with or without IVT.
