Intentional neck-plastic incomplete clipping followed by coil embolization for broad-necked distal BA aneurysms]

OBJECTIVE: We report three patients with broad-necked distal basilar artery (BA) aneurysms treated with intentional incomplete clipping followed by endovascular occlusion using Guglielmi detachable coils. METHODS: The location of the aneurysms was BA bifurcation in one patient and BA-superior cerebellar artery (SCA) in two. One patient presented with acute subarachnoid hemorrhage and two patients had incidental aneurysms. In two patients, endovascular treatment was thought to be difficult considering the morphology of the aneurysms and surgical treatment was performed as the first choice of treatment. One patient with a BA-SCA aneurysm underwent endovascular treatment using a remodelling technique first. However, it was impossible to place the coil preserving SCA, so surgical treatment was performed. In all patients, the attempt to pursue complete clipping was considered to be accompanied with high risks of morbidity, so neck-plastic incomplete clipping was performed intentionally. One to six days after the surgery, coil embolization was performed. RESULTS: In all patients, complete occlusion of the aneurysms was achieved and all patients had excellent clinical outcomes. CONCLUSION: Intentional neck-plastic incomplete clipping followed by endovascular coiling may be a useful treatment option for patients with broad-necked distal BA aneurysms.     

Treatment of ruptured intracranial aneurysms: our approach.

OBJECTIVE: Subarachnoid hemorrhage (SAH) often results in devastating neurological deficits requiring hospitalization and loss of independence. This is often a difficult time for patients and their families who are struggling to cope with this sudden illness. Current treatment options include surgical clipping of the aneurysm or endovascular obliteration using Guglielmi detachable coils. Our purpose in writing this paper was to review the factors that determine the choice of treatment. In addition to this we wanted to study the benefits of surgical clipping for ruptured aneurysms over endovascular coiling. MATERIAL AND METHODS: We studied--retrospectively--450 cases of ruptured cerebral aneurysms admitted to our institution from 1997 to 2003. Out of these, 324 were subjected to surgical clipping and 126 to endovascular techniques. The outcome was studied using the Glasgow Outcome Score (GOS). RESULTS: Of the 324 cases of surgical clipping 222 had a good recovery, 38 had moderate disability, 15 had severe disability, 13 became vegetative and 36 patients died. In the endovascular group 34 had a good recovery, 22 had moderate disability, 18 had severe disability, 15 became vegetative and 37 patients died. Grade to Outcome was compared for both forms of treatment. In our series clipping for ruptured aneurysm was preferred to coiling in fusiform-shaped aneurysms, large or giant aneurysms, MCA aneurysms, blister aneurysms, complex configurations, partially thrombosed aneurysms and aneurysms associated with cerebral hemorrhage. Coiling was performed for basilar tip and trunk aneurysms, high anterior communicating artery aneurysms, patients in subacute stages of subarachnoid hemorrhage, and those with associated medical complications. CONCLUSION: Based on this study we were able to formulate a few definite indications for clipping, even in the times of advanced endovascular techniques. In addition we could also prove the benefits of surgical clipping over the endovascular technique in severe subarachnoid hemorrhage.     

Combined microsurgical and endovascular management of complex intracranial aneurysms

OBJECTIVE: The disciplines of microneurosurgery and cranial base surgery have reached maturity, and technical advances in the surgical management of aneurysms are limited. Although most aneurysms can be clipped microsurgically or coiled endovascularly, a subset of patients may require a combined approach. A consecutive series of patients with aneurysms in one surgeon's cerebrovascular practice was reviewed retrospectively to analyze strategies for integrating microsurgical and endovascular techniques in the management of complex aneurysms. METHODS: Between 1997 and 2001, 596 aneurysms in 491 patients were treated microsurgically by the senior author (MTL) at the University of California, San Francisco, and 77 of these patients (96 aneurysms) were managed with a multimodality approach comprising a total of eight different combinations: selective revascularization and aneurysm occlusion (n = 23), endovascular and surgical trapping (n = 1), clipping of the aneurysm after attempted or incomplete coiling (n = 22), coiling after attempted or incomplete clipping (n = 5), clipping of recurrent aneurysm after coiling (n = 6), coiling of recurrent aneurysm after clipping (n = 1), clipping and coiling of multiple remote aneurysms (n = 13), and coiling after previous surgery (n = 6). RESULTS: A total of 96 aneurysms were treated with combined therapy, of which 43% were large or giant in size and 34% had fusiform or dolichoectatic morphology. Complete angiographic obliteration was achieved in 91 aneurysms (95%). Overall, 66 patients (86%) had good outcomes (Glasgow Outcome Scale score of 4 or 5; mean follow-up, 9 mo). The treatment mortality rate was 9.1% (seven patients), and permanent treatment-associated neurological morbidity rate was 5.2% (four patients). CONCLUSION: Evolving endovascular technologies need to be integrated into the microsurgical management of aneurysms. Multimodality approaches are best used with complex aneurysms in which conventional therapy with a single modality has failed. Revascularization remains a unique surgical contribution to the overall management of aneurysms with which current endovascular techniques cannot be used. Multimodality management should be considered an elegant addition to the therapeutic armamentarium that, through simplification and increased safety, improves the treatment of complex aneurysms beyond what is achievable by performing clipping or coiling alone.     

Surgery following endovascular coiling of intracranial aneurysms

BACKGROUND: Surgery for intracranial aneurysms that have been treated by endovascular coiling is a new challenge for neurosurgeons and the need for it will undoubtedly continue to increase. The indications for, timing, and technique of surgery in our experience are described. METHODS: We have reviewed our experience with 11 patients who underwent surgery following endovascular coiling with Guglielmi detachable coils (GDCs) of an aneurysm. We analyzed the indications for surgery, surgical techniques used, and patient outcome. RESULTS: There were nine female and two male patients. The mean age was 49 years (range 13 to 67 years). The intervals between coiling and surgery were 1, 2, 3, 4, 7, 7, 10, and 14 days, 6 weeks, 2, 18, and 25 months. The indications for surgery were partial treatment (3), growth of residual neck (2), persistent mass effect of a giant aneurysm (1), mass effect from the coil ball (2), coil migration (2), and coil protrusion with embolic event (1). The coils were removed at the time of surgery from 9 of 11 aneurysms before clipping. In two cases it was possible to place a clip across the neck of the aneurysm without removing the coils, as the coils no longer occupied the neck.There were two permanent deficits directly related to the endovascular procedures. Two other patients who presented with subarachnoid hemorrhage had residual neurological deficits post surgery and one patient with a giant aneurysm had persistent visual loss. CONCLUSION: Surgery remains a viable option at any time for treating aneurysms that have been previously treated by GDC placement. The operative approach is determined by the need for coil removal and the duration since coiling.     

The impact of interventional neuroradiology on neurosurgical training

Aneurysmal subarachnoid haemorrhage carries a high mortality and morbidity. Surgical treatment (craniotomy and clipping of the aneurysm) has been, until recently, the gold standard treatment. Endovascular embolisation treatment has rapidly evolved and the evidence available suggests that the results are as good as surgery. Endovascular treatment successfully occludes the aneurysm to prevent re-haemorrhage, whilst reducing the procedural morbidity when compared to craniotomy and clipping. It is perceived to be of particular benefit for aneurysms in the posterior cerebral circulation where operative morbidity and mortality are significantly higher than for aneurysms on the anterior circle of Willis. The establishment of endovascular treatment has reduced the number of cases being treated surgically, and this has had a significant effect on surgical training. We analysed the management of all ruptured aneurysms treated in our unit over a 4-year period. During the same period, an endovascular service was established in the unit. We devised a novel system for the angiographic grading of aneurysms in order to evaluate the impact that coiling has had on surgical training. The results show that as few as four aneurysms per year would be appropriate for specialist registrars to operate upon. We propose some mechanisms for maintaining high quality surgical training.     

Oculomotor nerve palsy due to posterior communicating artery aneurysm: Clipping vs coiling

ObjectivePosterior communicating artery aneurysms (PCoAA) usually present with brain hemorrhage, but they might present with oculomotor nerve palsy (ONP) in about one out of five patients. Treatment options include endovascular coiling and surgical clipping. The present analysis aims to compare the two treatment options for ONP due to PCoAA in terms of complete recovery and related parameters.MethodsA comprehensive literature search was performed for studies published between 2000 and 2019 on ONP due to PCoAA. The included studies were divided into two categories—surgical clipping (group A) and endovascular coiling (group B). The collected data were statistically processed with SPSS version 25.ResultsThere was a significant difference between the two treatment groups regarding complete recovery of ONP (P < 0.001), suggesting superiority of the surgical clipping. The correlation analysis showed no correlations for group A. Group B had negative and positive correlations, showing that endovascular coiling results in higher rates of complete ONP recovery for elderly patients.ConclusionSurgical clipping is superior to endovascular coiling in terms of complete recovery among patients with ONP due to PCoAAs. Endovascular coiling seems to benefit older patients. While no recommendations exist for the treatment of ONP due to intracranial aneurysms, an increasing number of studies imply the superiority of operative clipping.     

Surgical strategies for aneurysms deemed unclippable and uncoilable

Although most cerebral aneurysms can nowadays be successfully treated either by standard clipping or sole coiling, a subset of aneurysms may not be amenable to standard clipping or coiling and require alternative treatment options. Surgical options, other than clipping and/or endovascular options other than sole coiling, may be the optimal treatment plan for some complex aneurysms. Surgical strategies for such complex aneurysms include parent artery occlusion, revascularization procedures and flow redirection. In this article, we review which factors are predictive of failure of conventional aneurysm treatment options; summarize key information needed to orient treatment decision; and discuss surgical options for unclippable and uncoilable aneurysms.     

Distal anterior inferior cerebellar artery aneurysms: report of three cases and literature review

Aneurysm at the distal portion of the anterior inferior cerebellar artery (AICA) is uncommon and only 55 cases have been documented in the literature. Here we report an additional three cases with review of the literature. All three patients presented with subarachnoid hemorrhage. The ruptured aneurysms were located at the meatal loop of the AICA in all three patients and one patient had another unruptured aneurysm at the lateral branch distal to the meatal loop. Two patients underwent surgical trapping of the aneurysms, and the other patient was treated with endovascular coiling because of poor clinical condition. Increase of hearing disturbance was found in two patients who underwent surgery or endovascular coiling, respectively. Clinical features and treatment of these rare lesions are discussed with reference to the 7th and 8th nerve impairments as preoperative symptoms and postoperative complications.     

Retreatment of Recurrent Internal Carotid-Posterior Communicating Artery Aneurysm after Coil Embolization

Internal carotid-posterior communicating artery (IC-PC) aneurysms account for more than 20% of all intracranial aneurysms. As a result of the increase in coiling, there has also been an increase in recurrent IC-PC aneurysms after coiling. We present our experience of 10 recurrent IC-PC aneurysms after coiling that were retreated using surgical or endovascular techniques in order to discuss the choice of treatment and the points of clipping without removal of coils. From 2007 to 2014, 10 recurrent IC-PC aneurysms after coiling were retreated. When the previous frames covered the aneurysms all around or almost around except a part of the neck, coiling was chosen. In other cases, clipping was chosen. Clipping was attempted without removal of coils when it was technically feasible. Among the 10 IC-PC aneurysms retreated, 3 were retreated with coiling and 7 were retreated with clipping. In all three cases retreated with coiling, almost complete occlusion was accomplished. In the seven cases retreated with clipping, coil extrusion was observed during surgery in six cases. In most of them, it was necessary to dissect strong adhesions around the coiled aneurysms and to utilize temporary occlusion of the internal carotid artery. In all seven cases, neck clipping was accomplished without the removal of coils. There were no neurological complications in any cases. The management of recurrent lesions of embolized IC-PC aneurysms requires appropriate choice of treatment using both coiling and clipping. Clipping, especially without the removal of coils, plays an important role in safe treatment.     

Quality of life after treatment for incidental, unruptured intracranial aneurysms

Summary Background. Discovering an intracranial aneurysm may profoundly affect the patient’s quality of life. Patients living with unruptured and untreated aneurysms often report symptoms of anxiety and depression. There are few trials studying the quality of life after treatment of unruptured intracranial aneurysms. We aimed to compare the quality of life and symptoms of anxiety or depression after endovascular coiling or open surgery clipping of unruptured intracranial aneurysms, in patients with no prior subarachnoid haemorrhage. Method. 73 living patients were included. 44 had undergone open surgery clipping and 31 had undergone endovascular coiling within the last 5.5 years. We registered a number of parameters from medical records and the patients’ current quality of life was assessed by a questionnaire. 63 of 73 (86.3%) returned our questionnaire, which included the Norwegian version of SF-36 and the Hospital Anxiety and Depression Scale (HAD). Findings. Many patients treated for unruptured intracranial aneurysms have a relatively low quality of life. The low scores indicate that the patients experience limitations in their ability to work or accomplish desired activities due to perceived physical or mental handicaps. There were no significant differences between the open surgery group and the endovascular group when comparing quality of life parameters after treatment. A subgroup analysis of patients with a favourable functional outcome also showed reduced quality of life without any differences in the two treatment groups. There were no signs of improvement in quality of life over time. Conclusion. Quality of life after treatment does not seem to be a strong argument for choosing one modality of treatment over the other in patients with unruptured intracranial aneurysms. There are no significant differences in the quality of life of patients successfully treated using endovascular technique and patients who underwent craniotomy and clipping. We speculate that the low quality of life scores are due to factors unrelated to the aneurysms. The scores possibly reflect characteristics of a patient group where incidental aneurysms are more frequently diagnosed while undergoing extensive imaging procedures due to unrelated symptoms.
