In this operative video, Dr. Cohen demonstrates the frontotemporal approach for clip ligation of a large calcified MCA aneurysm. A tandem clipping strategy is used with a straight fenestrated clip followed by a straight clip to close the distal and proximal aneurysm neck. Although ICG initially suggests no filling,... show more

Fenestrated clips are the most difficult to produce. But they are the most beautifull when they are ready. I work in a brazilian company from aneurysm clips.

Such a valuable operative case! 💛 The persistence despite calcification challenges and the ICG-vs-fluorescein discrepancy is a great teaching point

In this operative video, Dr. Cohen demonstrates a suboccipital craniotomy for proximal-to-distal PICA end-to-side anastomosis for treatment of a calcified fusiform distal PICA aneurysm. The distal temporary clip is removed, revealing backflow through the aneurysm, so a permanent curved clip is placed on the distal aneurysm segment to prevent continued filling. The remaining temporary clips are removed sequentially, with minimal bleeding at the anastomosis. Micro-Doppler and fluorescein angiography confirm good flow through the vessels, no aneurysm filling, and preserved perfusion of the fourth ventricular floor.

In this operative video, Aaron Cohen-Gadol, MD demonstrates the contralateral cross-court approach for clip ligation of a right P1 aneurysm through a left-sided pterional craniotomy. The basilar artery, its bifurcation, and the contralateral P1 segment are exposed, revealing a perforating vessel arising from the neck of the P1 aneurysm. The cross-court approach is effective in this case, as the anatomy provides favorable visualization for circumferential dissection of the neck. A temporary clip is placed on the basilar trunk to allow controlled manipulation of the neck for definitive clip application. The narrow working space medial to the carotid artery is used to inspect the perforating vessels. A long straight clip is then applied to collapse the aneurysm neck, providing adequate visualization around the blades to preserve the perforators.

“Dome protection,” or placing coils in the dome of a ruptured aneurysm, can prevent rehemorrhage but can complicate subsequent clipping. Coils ramp clips down onto the neck & constrict/block the parent artery. Here, I used posterior clinoid to anchor the clip & keep it from sliding…

In this operative video, Dr. Cohen demonstrates the supracerebellar transtentorial approach for resection of a medial tentorial meningioma. After devascularization, the tumor becomes more gelatinous and is removed with suction while posterior cerebral artery branches are protected to prevent occipital ischemia. The tumor-involved tentorium is then pulled into the resection cavity after its medial attachment is released. Smaller arachnoid bands are divided, the field is cleared, and the affected tentorial segment is removed. Final inspection shows no obvious residual tumor in the field.

In this operative video, Dr. Cohen demonstrates the telovelar approach for resection of a large hypervascular vermian hemangioblastoma. The interface between the hemangioblastoma and surrounding tissue is developed with coagulation and sharp dissection. As the dissection advances deeper, bleeding risk increases, so any capsular entry is controlled with further coagulation. The tumor is operated on from deep to superficial to protect the floor of the fourth ventricle while identifying larger anterior vessels. Only vessels clearly entering the tumor are coagulated, preserving cerebellar vessels and maintaining hemostasis near the fourth ventricular floor.

In this operative video, Dr. Cohen demonstrates staged retromastoid and pterional approaches for resection of a petroclival epidermoid tumor. Careful attention is paid to the fourth cranial nerve as it enters the tentorium near the petrous apex. Tumor along the posterior basal temporal lobe is removed through the supratrochlear working corridor. The portion anterior to the midbrain is dissected while the contralateral oculomotor nerve is identified and protected, permitting maximal safe removal of tumor extending toward the medial temporal lobe.

In this operative video, Dr. Cohen demonstrates resection of a cavernous sinus meningioma through a frontotemporal approach. The operation proceeds through the middle fossa, where the fibrous tumor is entered inferiorly and internally debulked to create working space. As the mass is reduced, the dissection follows the lateral wall of the cavernous sinus, with continued attention to the trigeminal nerve branches as they are identified and preserved. Further opening of the lateral cavernous sinus wall allows additional tumor removal until cavernous sinus venous bleeding defines the limit of safe resection.

is this the next thing after clipping? what’s the marketing tactic called on this platform? tiktok released a $NFLX competitor and they’re using ai slop to push the app this is literally INSANE, we’re living in a sci-fi age it’s no secret a lot of people prefer clips over full movies so tiktok created a platform for short dramas, basically like tiktok but just for movie clips but that’s not even the wild part most of the clips i saw isn’t from real movies, it’s ai-generated movie series, fuck creators are making these ai slop series like “fruit dramas,” and it somehow has a massive audience and tiktok is using its distribution moat to push the app so creators are making brainrot series and cross-posting on tiktok and the new app read this again: creators generating ai slop dramas, then clipping them and posting on their new app, like a clip of a clip this reminds me of the sora app that openai killed, but this might have a better future btw, 3 days ago, netflix said on their earnings call they’re about to release a tiktok-like vertical video feed for clips so yeah, this is probably the future before you even process what “clipping” is, people already invented clipping for clipping content

Here are the Ossoff "Natalie" clips back to back, for immediate context. Clip 1: He clearly wants to plant the idea that a female staffer is in an inappropriate relationship with Trump. Crowd loved it, and he soaks it in. Clip 2: Spins the innuendo as a broader critique on Trump's overall staffing approach. Psaki of course is there to provide mop up support. He and his staffers thought the smear would be a crowd-pleaser, and they were right. Just own that.

Our very own Alexander Chen created "Hello, world" a short film inspired by the technology of his childhood with Google Labs Flow. Here's a closer look at how he brought his vision to life: 1) All of the clips were generated in Flow using text-to-image prompts except he used image-to-video prompts for the close-up shots to ensure consistency and accuracy (and the images used were generated by Imagen). 2) To evoke the exact feelings of his childhood home, he used Google Street View for visual references then asked the Google Gemini to write descriptions and prompts, then uploaded those into Flow which is what produced such vivid and accurate renderings in the film. 3) Every sound used in the video is generated by Veo 3. However, to blend things together, he used a separate video editing software to extend the head and tail of each clip over the proceeding and following clip, occasionally crossfading the audio to help with transitions.

the future of POLITICS is clipping. Kevin O'Leary explained the clipping business indirectly. the people he pays most now take content, cut it into a 59-second clip, and bring in customers, because the work is measurable. swap customers for voters and that's a campaign. clipping isn't one ad buy with a ceiling. it's hundreds of creators turning one piece of content into thousands of clips that compound across every feed, and you only pay for the views that land. it's already everywhere. Netflix clips comedy specials. countries clip themselves for tourism. Zohran Mamdani streams for an hour as mayor of NYC and that hour turns into a week of clips across every platform. politics is just the next vertical, and the highest-stakes one. every future campaign will run this, local to federal. the ones that don't get outpaced by the ones that do.

This looks like Lahore: Clip 1. Protestors are angry because they were fired upon from this property and hence trying to break in. Clip 2. Protestors managed to break in the property. Clip 3. Protestors surrounded the soldiers who were firing. If anyone has information about location or more details on this then pls share. Straight fire (with live bullets) on protestors is a crime! #نکلو_خان_کی_زندگی_بچاؤ #ReleaseImranKhan

🚨 PEOPLE ARE FREAKING OUT OVER HOW EASY IT IS TO CROSS THE U.S.-CANADA BORDER A video is going viral showing someone standing in Canada, looking straight into the United States with almost no visible security. In some areas, people can literally walk across. While wooded stretches of the border have always been porous, this clip appears to show a more developed area with little to no barriers. Now Canada is responding by launching drone patrols along parts of the border in Alberta, Saskatchewan, and Manitoba targeting smuggling and illegal crossings. Is the border really this open?

Who are “THEY”? “We have to name the names” in the worst miscarriage of medical science in history. Is it the World Health Organization? Dr. David Martin says Tedros is just a puppet with a “giant stick up his ass.” “But who’s moving the stick for the puppet?” The answer is, according to Dr. David Martin: • Bill Gates • The Wellcome Trust • The Rockefeller Foundation “By 2023, which is kind of where we are right now, Gates represents 88% of the donations to the World Health Organization from donor organizations and agencies. By any definition, that’s a controlling interest.” Bill Gates is no philanthropist; he’s laundering money into the World Health Organization. And when Gates and others state that having vaccinations where they are needed could potentially lead to as much as a 20% reduction in the Earth’s population, according to Dr. Martin, “those are not allegations; those are stated objectives.” Much more was revealed in this 4-minute clip. Watch and listen to Dr. David Martin.
