San Antonio Spurs star Victor Wembanyama has been sidelined for the rest of the 2024-2025 NBA season, but not because of a sprained ankle or torn ligament. Instead, the 21-year-old phenom and last season’s Rookie of the Year is battling deep vein thrombosis (DVT), a serious blood clot condition that requires immediate medical attention.
DVT occurs when a blood clot forms in a deep vein, most commonly in the legs. But in Wembanyama’s case, the clot may have developed in his shoulder—a less common but equally concerning scenario.
“Many people don’t realize how serious blood clots can be,” says Michael Schwartz, MD, a vascular surgeon at WMCHealth. “A clot that moves to the lungs can block oxygen and be fatal. That’s why early detection and treatment are essential.”
Understanding DVT
While most people associate DVT with legs, Wembanyama’s may have occurred in a less common location. Although his exact diagnosis hasn’t been publicly confirmed, “A blood clot in the shoulder is relatively rare and is often due to a condition called Paget-Schroetter syndrome,” says Dr. Schwartz.
Paget-Schroetter syndrome occurs when the subclavian vein—a major vein near the shoulder—becomes compressed in the thoracic outlet, an area where the clavicle, first rib and surrounding muscles intersect. This compression can restrict blood flow, leading to clot formation. It’s most often seen in athletes or individuals who perform repetitive overhead motions, such as swimmers and baseball pitchers.
Recognizing the Symptoms and Risks
Blood clots, whether in the leg or shoulder, don’t always present obvious symptoms. However, signs of Paget-Schroetter syndrome can include:
- Swelling in the affected area
- Pain or tenderness
- A feeling of heaviness or tightness
- Skin discoloration (red or bluish tint)
- Warmth around the affected area
If untreated, a clot can break loose and travel to the lungs, causing chest pain, shortness of breath and, in severe cases, a life-threatening pulmonary embolism.
Risk factors include prolonged immobility, dehydration, genetic clotting disorders and repetitive upper-body strain.
Fortunately, when detected early, DVT is treatable with blood thinners, lifestyle modifications and, in some cases, minimally invasive procedures to remove the clot. Athletes like Wembanyama may also undergo rehabilitation to prevent future occurrences.
Protecting Your Health
Dr. Schwartz emphasizes that awareness and prevention are key. “If you notice swelling, pain or skin changes in your arms or legs, don’t ignore them. Blood clots can happen to anyone, and seeking medical attention early can be lifesaving.”
Whether you’re an athlete or not, staying active, staying hydrated and recognizing the warning signs can help protect your vascular health.
