That’s a wrap for the inaugural @clotsheadtotoe ! It was amazing to participate & witness multidisciplinary conversations around thrombus management #headtotoe! What a stellar faculty at the one & only conference focused solely on CLOTS & that too at the happiest place on Earth!

Ended the week with a great PEN FLASH 3.0 case. Up and over and able to treat the infrapopliteal confluence and the saphenous collaterals. Went PTV and flossed from above (felt like an arterial case!) Treating the inflow may shift the paradigm!
venous disease experts need to be well versed in multiple techniques/devices. Still need better way to treat chronic distal fem/pop disease!
@clotsheadtotoe TIME!! See everyone in Orlando!

What's going on here?
Why did we place an IVC filter for a patient with Acute Limb Ischemia?
Every vascular interventionalist will eventually encounter this condition:
*Paradoxical embolism*
A clot from the venous system ends up in the arterial system through a right-to-left shunt 🫀
After IVC filter placement, arterial lytic + aspiration was performed, with a good outcome.
Keep this condition in the back of your mind when you consider acute limb ischemia causes! 🧠

Thoracic central vein obstruction is increasingly device-related. Endovascular recanalization and stent reconstruction enable rapid symptom relief and durable patency when guided by meticulous imaging, planning, and technique. bit.ly/3LYvS8Z

This might be the most badass brief report I’ve read in a long time.
In @NEJM
A team just published what feels like a glimpse straight into the future of cellular therapeutics: successful survival and function of transplanted allogeneic, CRISPR-edited beta cells with zero immunosuppression — in a real human with long-standing type 1 diabetes.
No anti-rejection meds.
No immune flare.
Glucose-responsive insulin secretion documented weeks after implantation.
A clean safety profile.
This is the kind of translational science that makes you think about how close we might be to rewriting what’s possible in autoimmune and metabolic disease.
Medicine is moving fast. This is one of those papers that makes you feel it.

A new Nature paper just delivered a shock to a long-lived oncology myth.
🔗 nature.com/articles/s41586-0…
For years we’ve been told that radiotherapy—and its cousins like SBRT, TARE, Y-90—might trigger the “abscopal effect,” a systemic immune response that helps control distant disease.
This study shows the opposite: radiation induces Amphiregulin (AREG) and can stimulate distant metastasis through myeloid-cell reprogramming.
So what does this mean for HPB oncology?
👉 The “abscopal effect” is not a clinical strategy. It’s a story.
👉 Radiation-driven systemic benefit is, at best, unreliable—and at worst, misleading.
👉 Surgery remains the only method of local control with reproducible impact on survival.
