An “old” meta-analysis: coiling versus microsurgical clipping in the treatment of unruptured MCA aneurysms

Key point: To compare endovascular coiling with microsurgical clipping among adults with unruptured middle cerebral artery aneurysms (MCAA) by conducting a meta-analysis. The widespread use of neurovascular imaging has increased the amount of intracranial aneurysms eccidentally detected. Although the lifetime risk of aneurysmal rupture in many cases is relatively small (approximately 1% per year), rupture Read more about An “old” meta-analysis: coiling versus microsurgical clipping in the treatment of unruptured MCA aneurysms[…]

Sex, Smoking, and Risk for Subarachnoid Hemorrhage

Key points: According to prospective cohort studies, smoking is the most important risk factor for unruptured intracranial aneurysms, correlating with their appearance, growth and rupture. In addition, earlier studies report that women are at higher risk for SAH with adjusted hazard ratios (HRs) from 1.4 to 1.9 compared with men. In this paper, published August, 2016, Read more about Sex, Smoking, and Risk for Subarachnoid Hemorrhage[…]

A raised bar for aneurysm surgery in the endovascular era

Key points: Despite microsurgical treatment of cerebral aneurysms has a documented history, the impressive progression of endovascular technology, techniques and skills, and the results of the International Subarachnoid Aneurysm Trial (ISAT) and the Barrow Ruptured Aneurysm Trial (BRAT) has altered the paradigm for treating intracranial aneurysms. These neurointerventional option have raised the bar for aneurysm surgery, in an era when most Read more about A raised bar for aneurysm surgery in the endovascular era[…]

Optimal first coil selection to avoid aneurysmal recanalization in endovascular intracranial aneurysmal coiling

Key points: Coiling, simple or balloon-/stent-assisted, is an endosaccular technique of treatment and a long-term follow-up is mandatory: the problem of aneurysmal recanalization remains and according to a systematic review, recanalization occurs in 20.8% of patients. The volume embolization ratio (VER) has recently been reported to be associated with aneurysmal recanalization. It is a general Read more about Optimal first coil selection to avoid aneurysmal recanalization in endovascular intracranial aneurysmal coiling[…]

Multiple FD stents for treatment of large and giant aneurysms: is it really useful? Quantitative flow measurement after placing a flow diverter for a distal internal carotid artery aneurysm

Chen CW1, Wong HF2, Ye YL1, Chen YL3, Chen WL4, Ou CH5, Tsai YH1. Key points: As everyone knows the flow diverter stent (FDS) disrupts blood flow into the aneurysm sac, maintaining normal blood flow through the parent vessel; sometimes, there is a neointimal proliferation across the device strut, that contributes to the aneurysm closure.

Headache and Treatment of Unruptured Intracranial Aneurysms

Arena JE1, Hawkes MA2, Farez MF1, Pertierra L1, Kohler AA1, Marrodán M1, Benito D3, Goicochea MT1, Miranda JC3, Ameriso SF4.   Key points: Despite several studies have mentioned the presence of headache (cluster headache, hemicrania continua, and migraine) in subjects with UIAs, in 18%-34% of cases, in general practice chronic primary headache is not usually Read more about Headache and Treatment of Unruptured Intracranial Aneurysms[…]

Safety results from the treatment of 109 cerebral aneurysms using the Woven EndoBridge technique: preliminary results in the United Kingdom.

Lawson A1, Molyneux A2, Sellar R3, Lamin S4, Thomas A4, Gholkar A5, Patankar T1. Pubmed   OBJECTIVE: The Woven Endobridge (WEB) device has been in clinical use for the treatment of brain aneurysms for the past 4 years. Observational studies to assess clinical outcome and related complications have been published. Clear evidence is required to Read more about Safety results from the treatment of 109 cerebral aneurysms using the Woven EndoBridge technique: preliminary results in the United Kingdom.[…]

Endovascular flow diversion for treatment of anterior communicating artery region cerebral aneurysms: a single-center cohort of 50 cases

Colby GP1, Bender MT1, Lin LM2, Beaty N1, Huang J1, Tamargo R1, Coon A1. Pubmed BACKGROUND: Flow diversion represents a novel but definitive treatment for recurrent and difficult-to-coil aneurysms of the anteriorcommunicating artery (ACoA) region, of which reports are limited. OBJECTIVE: To determine the effectiveness of the Pipeline embolization device (PED) in treating aneurysms in the Read more about Endovascular flow diversion for treatment of anterior communicating artery region cerebral aneurysms: a single-center cohort of 50 cases[…]

Academic impact and rankings of neuroendovascular fellowship programs across the United States.

Sonig A1,2, Shallwani H1,2, Levy BR2, Shakir HJ1,2, Siddiqui AH1,3,4,2,5. Pubmed OBJECTIVE Publication has become a major criterion of success in the competitive academic environment of neurosurgery. This is the first study that has used departmental h index-and e index-based matrices to assess the academic output of neuroendovascular, neurointerventional, and interventional radiology fellowship programs across Read more about Academic impact and rankings of neuroendovascular fellowship programs across the United States.[…]
