Case Basis

We present three cases of cerebral aneurysms (1 unruptured; 2 ruptured) treated with endovascular techniques in pregnancies. The first ruptured case is a 28-year-old female on 20th gestational week. After the endovascular coiling, the patient suffered persistent hemiparesis and delivered a healthy baby by cesarean section. The second ruptured case is a 25-year-old female on 36th week of pregnancy. She died of aneurysm re-rupture after delivery of a healthy baby by cesarean section. The third unruptured case is a 31-year-old woman on the 26th gestational week of pregnancy who died of a giant basilar tip aneurysm after stent-assisted coiling. Ruptured aneurysm obliteration should be prioritized followed by vaginal delivery or cesarean section. The decision regarding the treatment of unruptured aneurysms should be carefully considered on a case-by-case basis. Stent-assisted coiling may be applicable to aneurysm during pregnancy.

Procedural Outcomes

A good working view is critical for safe and successful endovascular treatment of cerebral aneurysms. In a few cases, endovascular treatment of cerebral aneurysms may be challenging due to difficulty in obtaining a proper working view. In this report of 6 cases, we described the advantage of using a distal intracranial catheter (DIC) to achieve better visualization of cerebral aneurysms hidden by a parent artery or its branches. Between September 2017 and January 2021, we treated 390 aneurysms with endovascular techniques. In 6 cases in which it was difficult to obtain a proper working view, the DIC was placed distally close to the aneurysm in order to remove the parent artery projection from the working view and obtain better visualization of the aneurysm. Clinical and procedural outcomes and complications were evaluated. The position of the DIC was above the internal carotid artery siphon in the 6 cases. All aneurysms were successfully embolized. Raymond–Roy class 1 occlusion was achieved in all 4 unruptured aneurysms, while the result was class 2 in the 2 ruptured aneurysms. Placement of the DIC was atraumatic without dissections or significant catheter-induced vasospasm in all patients. Transient dysphasia was seen in 2 cases and transient aphasia in 1. Using this technique, we have found it possible to better visualize the aneurysm sac or neck and thereby treat cases we otherwise would have considered untreatable.

The Ideal

Abstract The ideal treatment for intracranial aneurysms has been highly controversial in the last few decades. It is particularly difficult to decide between clipping vs. coiling when it comes to an aneurysm that has already been treated. The authors performed a review of the literature published in the last ten years amongst the main neurosurgical publications and make recommendations based on this evidence and the surgical experience of the eldest author of this paper (ES). A series of cases of recurrent, incompletely coiled aneurysms treated with surgery is presented. Conclusions: aneurysms with a convenient configuration and location for either clipping or coiling might be better managed by surgical clipping in young patients considering that this treatment achieves higher rates of occlusion with a lower incidence of rebleeding. In elderly patients, each case must be discussed.

BackgroundIntegration of data from clinical trials and advancements in technology predict a change in selection for treatment of patients with cerebral aneurysm.ObjectiveTo describe patterns of use and in-hospital mortality associated with surgical and endovascular treatments of cerebral aneurysms over the past decade.Materials and methodsThe data are 34 899 hospital discharges with a diagnosis of ruptured or unruptured cerebral aneurysm from 1998 to 2007 identified from the Nationwide Inpatient Sample (NIS). The rates of endovascular coiling and surgical clipping and in-hospital mortality among patients with an aneurysm are examined over a decade by hospital and patient demographic characteristics.ResultsFrom 1998 to 2007, 20 134 discharges with a ruptured aneurysm and 14 765 discharges with an unruptured aneurysm were identified. Over this decade, the number of patients discharged with a ruptured aneurysm was stable while the number discharged with an unruptured aneurysm increased significantly. The use of endovascular coiling increased at least twofold for both groups of patient (p<0.001) with the majority of unruptured aneurysms treated with coiling by 2007. Although whites were more likely than non-whites to undergo coiling versus clipping for a ruptured aneurysm (OR=1.30; 95% CI 1.13 to 1.48) and men with unruptured aneurysms were more likely than women to undergo coiling (OR=1.26; 95% CI 1.13 to 1.40), by 2007 differences in treatment selection by gender and racial subgroups were decreased or statistically non-significant. Over time the use of coiling spread from primarily large, teaching hospitals to smaller, non-teaching hospitals.ConclusionsThe majority of unruptured aneurysms in the USA are now treated with endovascular coiling. Although surgical clipping is used for treatment of most ruptured aneurysms, its use is decreasing over time. Dissemination of endovascular procedures appears widespread across patient and hospital subgroups.

Unruptured Cerebral Aneurysms

Object Considerable evolution has occurred in treatment options for cerebral aneurysms. Development of endovascular techniques has produced a significant change in the treatment of ruptured and unruptured intracranial aneurysms. Adoption of endovascular techniques and increasing numbers of patients undergoing endovascular treatment may affect health care expenditures. Geographic assessment of growth in endovascular procedures has not been assessed. Methods The National Inpatient Sample (NIS) was queried for ICD-9 codes for clipping and coiling of ruptured and unruptured cerebral aneurysms from 2002 to 2008. Patients with ruptured and unruptured cerebral aneurysms were compared according to in-hospital deaths, hospital length of stay, total hospital cost, and selected procedure. Hospital costs were adjusted to bring all costs to 2008 equivalents. Regional variation over the course of the study was explored. Results The NIS recorded 12,588 ruptured cerebral aneurysm cases (7318 clipped and 5270 coiled aneurysms) compared with 11,606 unruptured aneurysm cases (5216 clipped and 6390 coiled aneurysms), representing approximately 121,000 aneurysms treated in the study period. Linear regression analysis found that the number of patients treated endovascularly increased over time, with the total number of endovascular patients increasing from 17.28% to 57.59% for ruptured aneurysms and from 29.70% to 62.73% for unruptured aneurysms (p < 0.00001). Patient age, elective status, and comorbidities increased the likelihood of endovascular treatment (p < 0.00001, p < 0.00004, and p < 0.02, respectively). In patients presenting with subarachnoid hemorrhage (SAH), endovascular treatments were more commonly chosen in urban and academic medical centers (p = 0.009 and p = 0.05, respectively). In-hospital deaths decreased over the study period in patients with both ruptured and unruptured aneurysms (p < 0.00001); presentation with SAH remained the single greatest predictor of death (OR 38.09, p < 0.00001). Geographic analysis showed growth in endovascular techniques concentrated in eastern and western coastal states, with substantial variation in adoption of endovascular techniques (range of percentage of endovascular patients [2008] 0%–92%). There were higher costs in patients treated endovascularly, but these differences were likely secondary to presenting diagnosis and site-of-service variations. Conclusions The NIS database reveals a significant increase in the use of endovascular techniques, with the majority of both ruptured and unruptured aneurysms treated endovascularly by 2008. Differences in hospital costs between open and endovascular techniques are likely secondary to patient and site-of-service factors. Presentation with SAH was the primary factor affecting hospital cost and a greater percentage of endovascular procedures completed at urban academic medical centers. There is substantial regional variation in the adoption of endovascular techniques.

Treatment of very small ruptured cerebral aneurysms (< 2 mm) continues to present a challenge. These lesions are difficult to treat both with neurosurgical and endovascular techniques. A neurosurgical approach is still the treatment of choice for these lesions at many centers because of high rupture rates related to endovascular treatment; however, there are clinical circumstances in which the neurosurgical option cannot be offered. In their review of the literature, the authors did not find any series reporting endovascular treatment of these very small aneurysms. In the present study, the authors report their experience with the endovascular treatment of a series of 4 ruptured aneurysms smaller than 2 mm from neck to dome. They describe their technique of using a remodelling balloon to stabilize the tip of the microcatheter in the neck of the aneurysm without entering it at any time, and of inserting the coil from outside the sac to minimize the risk of intraoperative rupture, which is very high when conventional endovascular embolization is performed.

Basilar Tip Aneurysm

Basilar tip aneurysms are the commonest aneurysms of the posterior circulation and constitute around 5-8% of all cerebral aneurysms. Ruptured basilar tip aneurysms may present with signs and symptoms of subarachnoid hemorrhage (SAH) with sudden, extremely severe headache, nausea and vomiting, stiff neck, blurred or double vision, sensitivity to light, seizure, drooping eyelid and loss of consciousness. At times, the hemorrhage could be fatal, reaching mortality beyond 20%. Basilar tip aneurysms have complex anatomy and have always been considered difficult to treat. Two well-known options to treat basilar tip aneurysms include the microsurgical approach and the endovascular approach. Endovascular treatment is now a cost-effective, preferred and logical rationale for the management of intracranial aneurysms. This case reports the first ever coiling procedure that was performed at Ziauddin Hospital (North Campus) for a basilar tip aneurysm and the other major challenge faced at our center was that the neck was wide, hence requiring a supporting balloon.

Abstract THE MANAGEMENT OF unruptured cerebral aneurysms remains one of the most controversial topics in neurosurgery. To this end, we discuss the diagnosis and estimated prevalence of these lesions as well as review the literature regarding the rate of rupture for cerebral aneurysms and risks of operative intervention. Our interpretation of the literature concludes that aneurysms are present in approximately 1% of the adult population, varying between less than 1% in young adults to 4% in the elderly. The yearly risk of subarachnoid hemorrhage for an unruptured intracranial aneurysm is approximately 1% for lesions 7 to 10 mm in diameter. Based on these assumptions, we recommend that 1) with rare exceptions, all symptomatic unruptured aneurysms should be treated; 2) small, incidental aneurysms less than 5 mm in diameter should be managed conservatively in virtually all cases; 3) aneurysms larger than 5 mm in patients younger than 60 years of age should be seriously considered for treatment; 4) large, incidental aneurysms larger than 10 mm should be treated in nearly all patients younger than 70 years of age; and 5) microsurgical clipping rather than endovascular coiling should be the first treatment choice in low-risk cases. Critical to our guidelines is collaboration by a highly experienced cerebrovascular team of microneurosurgeons and endovascular neurosurgeons working at a tertiary medical center with a high case volume and using a decision-making paradigm designed to offer only low-risk treatments. In certain patients for whom both treatment and natural history carry high risks, such as those with giant aneurysms, nonoperative management is typically elected.

Development And Evolution

Subarachnoid hemorrhage (SAH) is usually caused by the rupture of an intracranial aneurysm. Craniotomy and surgical management has been the traditional treatment for decades until the development and evolution of endovascular techniques. Operative clipping of cerebral aneurysms is performed less frequently, but the procedure is still required for aneurysms that are not amenable to endovascular coiling. Some centers do not have the skilled personnel to perform endovascular techniques, and craniotomy is therefore necessary to treat the aneurysm and prevent the problem of rebleeding and avoid vasospasm. This discussion will address specifically the perioperative management of surgical clipping for intracranial aneurysms.

Abstract Ruptured cerebral aneurysm is a grave disease, with a high morbidity and mortality, mandating securing the aneurysm to eliminate fatal rebleeding.1 Multiple aneurysms are frequent and may occur in approximately 20% of the cases with female prominence.2 The risk of subarachnoid hemorrhage in unruptured aneurysms is higher in patients who had prior ruptured aneurysms.3 Hence, there is an indication of treating all concomitant aneurysms when one is ruptured. We present the case of clipping of 3 aneurysms via a cranioobritozygomatic (COZ) approach including a middle cerebral artery, anterior choroidal artery, and superior cerebellar artery in a patient presenting with subarachnoid hemorrhage and multiple aneurysms with suboptimal morphology for endovascular coiling. We highlight the advantages of the COZ in the clipping of complex posterior circulation aneurysms and the advantage of mobilization of neural structures to gain wider exposure.4-6 The temporal fossa space provided by zygomatic osteotomy allows the outward mobilization of the temporal lobe after freeing it by splitting the Sylvian fissure. The falciform ligament is opened overlying the optic nerve, allowing for safe dissection within the opticocarotid window. The oculomotor nerve is detethered from the dura surrounding its entry into the cavernous sinus. These maneuvers allow for mobilization of the critical neurovascular structures, which widens the operative corridor without undue traction or retraction. The COZ with clinoidectomy shortens and widens the operative field, allows for enhanced maneuverability, improved visualization, and exposure of the clinoidal carotid, and facilitates the release and mobilization of the optic and third nerve. The patient consented to surgery.  Image at 1:40 reprinted with permission from Al-Mefty O, Operative Atlas of Meningiomas. Vol 1, © LWW, 1998.
