I learned an incredible amount from this man during his last year at @MiamiVasc. He loved the fellows and his patients. Many of my verbal rebukes for my trainees come verbatim from him. “Are you metaphysically certain of that?” 🤣 He died too young. RIP Shaun. #ISETWeek2026

On Jan. 16, 1964, Dr. Dotter performed the first transluminal angioplasty, transforming medicine forever. Today, we celebrate this and all other great IR accomplishments that have come since. Celebrate with us; share your IR success stories using #WorldIRday!

🧵regarding 'the crimp' and other technical pointers having to do with securing surgical drains with suture. We'll go over my preferred method, other methods like the Roman sandal, some errors people make, and other factoids. (1/ )

When suturing a drain in place: If the suture (yellow arrow) and/or the portion of tubing it’s placed at (green arrow) is *too far away* from the entry point, as shown here, then the drain is free to constantly move back and forth like a piston. This may ⬆️ the infection risk.

You have demonstrated that you do not understand how this works, so I will demonstrate this for you and anyone who wants to read this: When CMS creates the fee schedule, there are 3 components to each code: -wRVU -peRVU -mpRVU Additionally, each code has a facility payment for services rendered in ASCs or hospitals (what CMS defined as facilities). The peRVU number for any given code is higher in a facility than it is in a physician office, since overhead such as staffing and equipment is payed by the facility via facility fees. Global payment for services in an office (which is the combined payment of all those 3 RVU factors above) tends to be much higher than the payment to a physician in a facility since the physician is responsible for using that money to cover overhead. The problem is that the money for physician services (the PFS) is declining each year. The money spent on facility fees is increasing each year. We have now reached a point where independent practice is becoming unsustainable which is reflected in the mere fact that 80% of physicians are now employed. Why is this? Multi factorial but the main reason is that declining PFS payments are not enough to cover the expenses of running a practice. In fact, within my world of the endovascular space, we have 195 CPT codes paid at rates less than their direct costs. Facilities are paid rates much greater than what we are paid for rendering the same service in an office. Here’s a nice example. Let’s pick IVC filter placement, CPT 37191 -payment in an office: $1938.21 -payment to a hospital: $5241.36 -payment to physician if done in a hospital: $210.19 If the product device costs $1500, my labor in an office is approximately $200/hour and the entire service from start to finish including recovery takes 1 hour, how do I make any money? We’re not even factoring malpractice, rent, insurance, capital expenses including ultrasound, c-arms and more. This isn’t propaganda. This is simple math and CMS national average data. Now play this out where expenses including labor expenses and supply costs are going up every year but that global payment in the office is going down. Not sustainable.

6. There is robust data from an ACR/SIR collaborative project that suggest that the providers and practices with the busiest E/M services have the most referrals, do the most complex work, and derive >90% of their practice revenue from procedural and E/M work. (more to come).

I can’t remember where I originally learned this or who taught it to me, but I am glad I now know what it is called and have a reference to show my trainees. This is how I close the running subcuticular stitch for every port I place. Great post! @SIRRFS
Repeat🧵describing the Aberdeen knot: an underappreciated surgical knot that is used to secure a running suture. It has been shown to be more secure than a square knot. We will cover how to do it, what not to do, and a modification that may make it more secure. (1/ )

Moving in the right direction but still lagging behind surgery. Thank you for all your hard work @womenirads - important for me as a PD to have a network to plug my female IR trainees into for mentorship and networking.
Attending IRs at 9.8%, integrated res at 22% women, huge improvement over the years! Keep up the amazing work @womenirads through mentorship and representation.

Another insurance denial. Another patient put at risk. We did everything right. My PA saw a patient with signs of a Deep Venous Thrombosis (a dangerous blood clot). We ordered an ultrasound, confirmed the diagnosis, and prescribed the medication to help prevent dangerous complications. But her insurance denied the medication. Why? They wanted “more clinicals.” Despite an in-person examination. Despite appropriate documentation. Despite the ultrasound result showing a blood clot. She was sent home from the pharmacy without the treatment she needed. If I failed to prescribe the medication, I would be held accountable for putting this patient at risk. When will we admit that insurance companies are practicing medicine? When will we hold companies and individuals accountable for delays in care? I am going to continue to share these denials with you so you can see what it is like to be a doctor in 2025. We have to fix this—for patients, for providers, for all of us. If you have a story, please share it with me. Let’s change this.
