blood clot

Colorado coach Deion Sanders returned to Buffaloes football practice Wednesday — just as Coach Prime said he would 24 hours earlier when he announced he would be undergoing a surgical procedure later that day related to blood clot issues.

A video posted by his eldest son, Deion Sanders, Jr., on his “Well Off Media” YouTube channel Wednesday starts with a clip of Sanders going into surgery. Then, after indicating a 16-hour time jump, the video shows Sanders walking briskly, if perhaps a little gingerly, through the Buffaloes’ indoor practice facility. He is offered a cart but apparently turns it down.

Much of the rest of the eight-minute video shows clips from the team’s practice. Sanders stays on the move, with his walking appearing a bit more labored as practice continues. Sanders is not seen at what appears to be the end of practice, as another coach addresses the players.

A spokesperson for Colorado football told The Times on Wednesday afternoon that the team expects Sanders to coach the Buffaloes on Saturday during their home game against No. 22 Iowa State.

No other information has been released on the surgery or Sanders’ condition.

During his weekly news conference Tuesday, Sanders revealed he’d be undergoing the surgical procedure — called an aspiration thrombectomy, which involves the left popliteal (located behind the knee) and tibial arteries — later that day. He said the surgery could take several hours.

“I’m going to be all right,” Sanders said. “Prayerfully, I’ll be right back tomorrow because I don’t miss practice. I don’t plan on doing such.”

On Saturday, Sanders could be seen either sitting down or limping around on the Buffaloes sideline during Colorado’s 35-21 loss to Texas Christian. He didn’t wear a shoe on his left foot during the second half and afterward told reporters he was “hurting like crazy.”

“I think I’ve got more blood clots,” said Sanders, who had two toes amputated on his left foot in 2021 because of blood clot issues and had a blood clot removed from his right leg in 2023. “I’m not getting blood to my leg. That’s why my leg is throbbing.”

The surgical procedure is said to be Sanders’ 16th in the last three years. He told reporters Tuesday that his struggles with blood clots are hereditary.

This summer, Sanders revealed that his bladder had been removed in May to address a cancerous tumor.

Janet Kukreja, Sanders’ doctor at the University of Colorado Cancer Center, told reporters at the same news conference that a section of Sanders’ intestine was reconstructed to function as a bladder and that the procedure was a success. She added that Sanders would not need radiation or chemotherapy treatments.

Sanders was a superstar cornerback in the NFL, playing for five teams over 14 years and winning two Super Bowls (with the San Francisco 49ers and the Dallas Cowboys). The 1994 defensive player of the year was an eight-time Pro Bowl selection and was inducted into the Pro Football Hall of Fame in 2011.

As coach at Jackson State from 2020 to 2022, Sanders led the Tigers to two Southwestern Athletic Conference titles and was named the SWAC coach of the year twice. He is in his third season at Colorado, where he has coached such stars at 2024 Heisman Trophy winner Travis Hunter (now with the Jacksonville Jaguars) and son Shedeur Sanders (now with the Cleveland Browns).

Matthew Stafford will start at quarterback and the plan is for Alaric Jackson to start at left tackle on Sunday in the season opener against the Houston Texans at SoFi Stadium, Rams coach Sean McVay said Monday.

Stafford, 37, practiced the last few weeks after sitting out training camp and several weeks because of a back issue.

“He’ll be good,” to start against the Texans, McVay said during a videoconference with reporters after the Rams completed a no-pads practice that was closed to the media.

Jackson, who signed a $35-million extension in March, practiced Monday for the first time since he was diagnosed with blood clots in his legs in June. Jackson had been doing individual drills with trainers and had participated with starters in jog-throughs.

“He earned the right to be in the position, where you pay him — it was a big priority for us to get him back,” McVay said. “He’s done everything in his power to be ready to go. This was always the end goal in mind — is to be ready to go against the Texans.”

After Jackson was diagnosed with blood clots for the second time in his career — he also dealt with the issue in 2022 — the Rams signed veteran tackle D.J. Humphries. Warren McClendon Jr. and David Quessenberry are other tackles that could play opposite right tackle Rob Havenstein if Jackson is injured, limited or struggles.

But McVay sounded optimistic that the Rams would continue to manage Jackson’s condition and that he would be ready for Sunday.

“He’s taken great care of himself, and he’s put himself in a rare position that I do believe to step in and play at a good clip,” McVay said, adding, “There’s nothing like actually playing real football … but [Monday] was a great step in the right direction.”

Earlier this week, President Trump was diagnosed with chronic venous insufficiency, or CVI, after he noted mild swelling in his lower legs. White House physician Dr. Sean P. Barbabella in a memo July 17 said the swelling prompted a full medical evaluation, including ultrasound tests and blood work. Those confirmed CVI, a condition the doctor described as “benign and common — particularly in individuals over the age of 70.” Dr. Barbabella said he found no other signs of more serious cardiovascular issues like blood clots and declared the president to be in “excellent health.”

What is chronic venous insufficiency?

“CVI is when the veins of the body do not work well,” said Dr. Mimmie Kwong, assistant professor of vascular surgery at UC Davis Health, when veins cannot transport blood effectively, causing it to pool, especially in the legs.

CVI is one of the most common vein problems in the U.S. and worldwide, affecting “about one in three adults in the United States,” Kwong said.

That translates to more than 30 million people in the U.S., most often older adults, according to Dr. Ali Azizzadeh, a professor and director of Vascular Surgery at Cedars-Sinai and associate director of the Smidt Heart Institute. He noted the condition is more common in women.

As people age, the veins, such as in their legs, may have a harder time returning blood to the heart, he said.

What causes CVI?

The valves in the veins of the legs are supposed to keep blood moving in one direction: back toward the heart. But when those valves are damaged or weakened, they can stop working properly, leading blood to flow backward and collect in the lower legs.

Individuals who stand or sit for extended periods, or those with a family history of vein issues, may be at a higher risk of developing the condition.

“When the calf muscles are active, they pump the veins that return blood from the legs to the heart,” Azizzadeh explained. “With prolonged inactivity of those muscles, blood can pool in the legs.”

What does CVI feel like?

While CVI isn’t always painful, it can cause discomfort that worsens as the day goes on.

The mornings may feel the best: “The legs naturally drain while you are lying down and sleeping overnight,” said Azizzadeh, “so they will typically feel lightest in the morning.”

As the day progresses and blood starts to pool, people with CVI may experience swelling, heaviness, aching or a dull pain in their legs. The symptoms tend to worsen after prolonged periods of standing or sitting.

If swelling worsens, thickening, inflammation or dry skin can result, with more severe cases developing wounds that do not heal and can even result in amputation, Kwong said.

How is CVI treated?

Ttreatment is more manageable when problematic veins are closer to the surface of the skin, Kwong said. It’s more problematic when deep veins are affected.

The first line of treatment is usually simple lifestyle changes. “We suggest CEE: compression, elevation, and exercise,” Azizzadeh said. Wearing compression stockings can help push blood out of the legs; elevating the legs allows gravity to help drain blood from the legs toward the heart, and regular walking forces calf muscles to pump blood throughout the body.

For people with more serious cases, doctors may recommend a minimally invasive procedure that uses heat to seal off the leaky veins. Common treatments include ablation techniques, surgical removal of veins (phlebectomy), or chemical (sclerosant) injections. “All of these therapies aim to cause the veins to shut down, so they no longer cause the CVI,” Kwong said.

In President Trump’s case, the condition appears to be mild and manageable. His doctors emphasized there was no cause for concern and that he remains in good overall health. But for millions of Americans living with CVI, recognizing the symptoms and knowing how to manage them can make a big difference in day-to-day comfort and long-term well-being.
