Limb Salvage in Acute Limb Ischemia and Diabetic Foot Gangrene Associated with Pancreatic Acinar Cell Carcinoma-Related Hypercoagulability.

This case report describes a patient with type 2 diabetes who developed sudden blockage of blood flow to the leg (acute limb ischemia) and a rapidly worsening diabetic foot ulcer with gangrene. The underlying cause was later found to be a rare pancreatic tumor that made the blood abnormally prone to clotting. Doctors used a step-by-step approach to save the limb, including surgery to remove dead tissue and infected bone, skin flap reconstruction, antibiotics, blood thinners, and strict blood sugar control. The wound healed and the patient regained function, but the pancreatic tumor had spread to the liver and required additional treatment. This case highlights that in some diabetic patients with foot gangrene, hidden cancers may be a trigger for blood clots, and a team of specialists is essential for successful treatment. However, as a single case report, its findings may not apply to all patients with diabetic foot ulcers.

Key takeaways

  • A diabetic patient with foot gangrene had a hidden pancreatic tumor causing blood clots, leading to blocked leg arteries.
  • A combination of surgery, antibiotics, blood thinners, and glucose control successfully saved the limb.
  • Doctors discovered the pancreatic tumor only after treating the foot, showing the need for thorough check-ups.
  • If you have sudden leg pain, coldness, or darkening skin, seek urgent care as this may be a blood clot.
  • Ask your doctor if a blood clot disorder or hidden tumor could be causing your foot ulcer, especially if it worsens fast.
  • A team of specialists, including surgeons and oncologists, is crucial for managing complex diabetic foot cases.

Editor's note

This case underscores the importance of a multidisciplinary approach in China's specialized diabetic foot centers, where vascular surgeons, endocrinologists, and oncologists collaborate. While advanced surgical techniques like staged debridement and flap reconstruction are available in major hospitals, the recognition of cancer-related clotting as a cause of foot gangrene is rare. Patients with rapidly worsening foot ulcers should discuss systemic screening with their care team.
