OBJECT The present purpose is to define the sensitivity of the superiority of coil embolization observed in the International Subarachnoid Aneurysm Trial (ISAT) according to the rate of late rebleeding over a reasonable range, and to find the range of rebleeding rates for which it may be overturned. In the ISAT, coil embolization appears to be safer than clip ligation at 1 year, and clip occlusion has better long-term efficacy at preventing rebleeding. This leaves open the question of which is…

Clipping versus coiling for ruptured intracranial aneurysms after the international subarachnoid aneurysm trial. United Kingdom experience.
The International Subarachnoid Aneurysm Trial (ISAT) was designed as the first multi-central international prospective randomized trial aiming to compare the safety and efficacy of the 2 available
Surgical clipping as the preferred treatment for aneurysms of the middle cerebral artery
TLDR
Surgical clipping is recommended as the principal treatment strategy for MCA aneurysms not only ethically defendable in view of the surgical results but also in line with a strategy to maintain surgical experience within centralized neurovascular centers.
International Subarachnoid Trial in the Long Run: Critical Evaluation of the Long‐term Follow‐up Data From the ISAT Trial of Clipping Vs Coiling for Ruptured Intracranial Aneurysms
TLDR
This article critically evaluates the long-term ISAT data from an evidence-based perspective and places it in the context of the overall approach to treatment of ruptured intracranial aneurysms, and concludes that the evidence for the superiority in coiling in the long term should not be assumed from ISat data alone.
Aneurysmal Subarachnoid Hemorrhage: Outcome of Aneurysm Clipping Versus Coiling in Anterior Circulation Aneurysm.
TLDR
Endovascular coiling of anterior circulation aneurysms is safe and as effective and successful as aneurYSm clipping and is less invasive also.
Aneurysmal Neck Clipping as the Primary Treatment Option for Both Ruptured and Unruptured Middle Cerebral Artery Aneurysms
TLDR
Compared to endovascular treatment, surgical neck clipping for both ruptured and unruptured MCA aneurysms results in a significantly higher complete obliteration rate and less regrowth, and is recommended as the primary treatment option rather than coil embolization.
Clipping versus Coiling for Intracranial Aneurysms: Recent Trends
TLDR
There is strong evidence to indicate that Endovascular Coil embolization is associated with better outcomes compared to Neurosurgical Clipping in patients amenable to either strategy.
The Barrow Ruptured Aneurysm Trial.
TLDR
Although a policy of intent to treat favoring coil embolization resulted in fewer poor outcomes at 1 year, it remains important that high-quality surgical clipping be available as an alternative treatment modality.

TLDR
Oral nimodipine has an established role in the management of DCI, along with maintenance of euvolemia and induced hypertension, and adenosine is found to be beneficial for transient induced hypotension in 2 retrospective analyses, without increasing the risk for cardiac and neurological morbidity.

Rates of Delayed Rebleeding From Intracranial Aneurysms Are Low After Surgical and Endovascular Treatment
TLDR
Rerupture of aneurysms treated by either coil embolization or surgical clipping is rare after the first year, and late retreatment is more common after coil emblization than after clipping but complication rates are low.
Treatment of Unruptured Cerebral Aneurysms by Embolization with Guglielmi Detachable Coils: Case-fatality, Morbidity, and Effectiveness in Preventing Bleeding—A Systematic Review of the Literature
TLDR
GDC embolization of UCAs is relatively safe, and the outcome is progressively improving, according to the case-fatality and permanent morbidity rates and the postembolization bleeding rate.
Regrowth of aneurysm sacs from residual neck following aneurysm clipping.
TLDR
It is found that 1- to 2-mm residual necks seen in postoperative angiography have been thought to pose little risk, but a surprising number of cases have been presented in which this seemingly unimportant remnant of the neck dilated over a long period to become a dangerous aneurysm.

Follow-up screening after subarachnoid haemorrhage: frequency and determinants of new aneurysms and enlargement of existing aneurysms.
TLDR
The results suggest that intracranial aneurysms should not be considered as a single event in a lifetime but rather as a continuous process.

TLDR
Surgical clipping can offer better results than CE, even for more complex aneurysms of the anterior circulation, especially for those involving the middle cerebral artery cases.

TLDR
The clinical and postembolization outcomes in patients treated with the GDC system have improved in the past 5 years, and aneurysm recanalization is still a major limitation of current GDC therapy.
Incidence of Recurrent Subarachnoid Hemorrhage After Clipping for Ruptured Intracranial Aneurysms
TLDR
After SAH, the incidence of a recurrence within the first 10 years is 22 times higher than expected in populations with comparable age and sex and whether this increased risk justifies screening for recurrent aneurysms in patients with a history of SAH requires further study.
