OCT shows ~11% vessel coverage after DCB. And yet, we think we’ve delivered therapy. Maybe it’s not the device. Maybe it’s the patient/lesion. Better imaging is necessary! #CX2026 @AlanLumsdenMD @VascularABC @DeBakeyCVedu

It was great to be part of the @JVascSurg Journal Club tonight and have our published work on UTE MRI and endovascular technical failure @HMethodistCV
Thank you @JVascSurg for highlighting our paper this evening for the JVS journal club! Great discussion and looking forward to more collaborations in the future! @mhumphriesmd @VikKashyapMD @AeroMD @VascularABC @AlanLumsdenMD @DeBakeyCVedu

Beautiful day in San Diego to kick off #SCVS2026. What does it take to go from being a vascular surgeon to being a chief? A chair? In the c-suite?

@trisharoymd A dynamic vascular scientist who is pushing the boundaries in her field with a great team! @VascularABC
🌟 AUTHOR SPOTLIGHT: Dr. Trisha Roy 🌟 Visualizing the invisible: How drugs interact with complex plaque. In a recent #EJVESForum study, @TrishaRoyMD and her team at Houston Methodist and Weill Cornell Medical College developed a groundbreaking Scanning Electron Microscopy (SEM) approach to evaluate how paclitaxel is deposited from Drug-Coated Balloons (DCBs). 🔍 MEET THE AUTHOR: Affiliations: Houston Methodist Hospital & Weill Cornell Medical College, Houston, TX, USA 🇺🇸. Expertise: A pioneer in using advanced imaging and human cadaveric models to study peripheral artery disease (PAD) and endovascular outcomes. The Vision: Moving beyond animal models to understand how vessel preparation—like cutting balloons—changes drug transfer in real human calcified lesions. 💡 WHY THIS RESEARCH MATTERS: Current DCB data often comes from healthy animal vessels, which don't mimic the "rock-hard" calcium surgeons face daily. Dr. Roy’s work uses a human cadaveric PAD model to show that vessel preparation significantly impacts how much drug actually stays on the vessel wall. 🚀 THE CLINICAL IMPACT: By using SEM to map drug distribution at a microscopic level, we can finally see why some lesions respond to DCBs while others don't. It’s about optimizing every millimeter of the artery for the best long-term patency.

When using DCBs, how much drug actually gets to the vessel wall? Plaque morphology matters and SEM can show us. Time to personalize our treatment strategies to the patients lesions and not rely on “one size fits all” for PAD! @AlanLumsdenMD @DeBakeyCVedu

Huge congrats to Eniko Pomozi for winning First Prize #AVF2026 @VenousForum! Proud of our lab @HMethodistCV where we combine MRI, histo, human thrombus to understand clot biology and treatment. Amazing work by Eniko team. Check us out at European Venous Forum in June!

should be illegal for managers to sub defenders on 59min currently holding a clean sheet ie preventing the 2 points for 60min plus the clean sheet points @ManCity 🤣 Don't they know the world revolves around my @OfficialFPL score @BBCSport says subbed at 60min #gimmedapoints 🤣

Congratulations to our post doc Eniko! Highlighted in the #VEITH bulletin. Pushing PAD beyond anatomy toward biology-guided diagnosis is exactly the paradigm shift the field needs. HiPath is a powerful vision for what’s next. @AlanLumsden @HMethodistCV @DeBakeyCVedu

Big day at HMH PVD Device Core with the TCAT team (MicroVention/@Terumo), we tested next-gen BTK devices on real CLTI pathology: donated limbs, phenotyped with MRI OCT. The future is informed design: the right device, right patient, first time, every time. @AlanLumsdenMD
