Because the spleen is highly vascular and fragile, it's one of the most vulnerable organs in the abdomen and can be easily damaged.What is a ruptured spleen?The spleen, a soft, fist-sized organ in the upper left abdomen, filters and stores about a quarter of the body's red blood cells and platelets while producing white blood cells to fight infections. Its delicate structure and thin outer capsule make it highly prone to injury from blunt trauma. A rupture can cause severe internal bleeding and demands immediate medical attention, often requiring surgery.Most splenic ruptures result from traumatic injuries, with car accidents accounting for nearly 50% to 75% of cases. Contact sports such as football and hockey also pose significant risks. In some cases, violent impacts like punches, stabbings, or gunshot wounds can cause the rupture. The spleen may tear immediately upon impact or later due to internal swelling from the injury."Shreyas Iyer sustained an impact injury to his left lower rib cage region... He was taken to the hospital for further evaluation. Scans have revealed a laceration injury to the spleen. He is under treatment, medically stable, and recovering well," the BCCI said in a statement on Monday."The BCCI Medical Team, in consultation with specialists in Sydney and India, is closely monitoring his injury status. The Indian Team Doctor will remain in Sydney with Shreyas to evaluate his day-to-day progress," the statement added.The 30-year-old will remain under observation for 2-7 days.
