What should neurointerventionalists know about cost-effectiveness research, and why should they care?
Health economic research, and particularly cost-effectiveness studies, are gaining increasing importance in medicine, and neurointervention is no exception. In light of rapidly increasing healthcare expenditure in almost every country, cost-effectiveness evaluations have become an important factor for policy decisions on healthcare use and adoption/reimbursement of new treatments. Specifically, politicians, policy makers, and third-party payers have to balance expenditure for neurointerventional treatments with expenditure in other sectors of healthcare, such as cancer treatments or preventive medicine. For a treatment to ...

Neuroendovascular robotics: wave of the future or failed promise?
In 2019, Siemens Healthineers (Erlangen, Germany) purchased Corindus Vascular Robotics, Inc (Waltham, Massachusetts, USA) for a staggering $1.1 billion. At the heart of this purchase was the CorPath GRX system which robotically assisted cardiac and neurointerventional therapy. It appeared the forefront of neuroendovascular robotics was coming into focus. However, in 2023, Siemens announced plans to scupper this newly acquired system at an estimated loss of $362 million as the "use of Corindus robots for cardiology operations did not fulfill our expectations". Robotic vascular intervention within the company transitioned to...

Correspondence on "ChatGPT in nuclear medicine education" by Currie and Barry
This study looks at how the GPT 3.5-powered ChatGPT chatbot affects academic integrity in nuclear medicine training facilities. Examinations and written assignments were tested using ChatGPT and the replies were compared with student cohorts for resemblance and performance. ChatGPT scored poorly in calculation-style assessments and failed in written tasks, with worse performance in higher-level courses, according to the study. While ChatGPT poses a...

Bailout endovascular techniques applied in a complicated basilar thrombectomy case
Patients with stroke symptoms due to acute basilar artery occlusion can benefit from endovascular thrombectomy.1 2 Several papers have reported unwanted events during thrombectomy procedures such as breakage, fragmentation, or even intravascular migration of the devices or catheter pieces. These papers also presented methods or techniques to retrieve defective devices such as a snare, retrievable stents, or balloons.3–6 Video 1 presents a case of basilar thrombectomy that was complicated with fragmentation and then distal migration of a Marksman microcatheter tip into the left posterior cerebral artery. The video s...

The reversed umbrella: displacement of a Contour device into an MCA aneurysm 18 months after treatment
We describe a first case of Contour device displacement 18 months after initial treatment. A patient with a 10 mm unruptured right middle cerebral artery bifurcation aneurysm was treated with a 9 mm Contour. The device was correctly positioned at the neck during treatment and at the 6 month angiography follow-up. At 18 months follow-up we noticed a full displacement of the device into the aneurysm dome. The Contour had a reversed shape and the aneurysm was still fully opacified. No neurological event occurred during the whole follow-up. Contour may be a promising tool but needs to be assessed over a long-term period. (Sour...

National Institutes of Health grant funding for cerebrovascular diseases
Conclusion Cerebrovascular disease receives roughly US$700 million in NIH funding. Ischemic stroke accounts for the majority of NIH-funded cerebrovascular projects, and R01 grants are the most common funding mechanism. Notably, NHLBI provides a large proportion of funding, in addition to NINDS. (Source: Journal of NeuroInterventional Surgery)

Endovascular intervention for the treatment of epistaxis: cone beam CT review of anatomy, collateral, and treatment implications/efficacy
We present a review of epistaxis treatment, a detailed description of anatomic and physiologic considerations informed by cone beam CT imaging, and a proposed protocol for sphenopalatine embolization for which there is currently no standard. (Source: Journal of NeuroInterventional Surgery)

Anticoagulation helps shrink giant venous lakes and arteriovenous fistulas in dural sinus malformation
Conclusions Anticoagulants may help to potentiate transarterial embolization in DSMs in babies by decreasing venous dilatation and reducing the remaining arteriovenous shunt, particularly the pial feeders. We did not observe recurrence of arteriovenous shunts after treatment, especially during anticoagulation treatment. Further studies are needed to support our findings.

Effects of intravenous thrombolysis on stent retriever and aspiration thrombectomy outcomes: a systematic review and meta-analysis of the randomized controlled trials
Conclusions Our findings suggest that SR and ASP thrombectomy have comparable safety and efficacy profiles, regardless of prior IVT administration. Additionally, our results indicate that the addition of IVT may improve certain efficacy outcomes based on the employed first-line MT technique. (Source: Journal of NeuroInterventional Surgery)

Optimized density and locations of stroke centers for improved cost effectiveness of mechanical thrombectomy in patients with acute ischemic stroke
Conclusion The combination of optimization modeling and cost effectiveness analysis provides a powerful tool for configuring the extent and locations of CSCs (and TSCs).
