Delayed Radiation Injury Treatment with Hyperbaric Oxygen Therapy (HBOT) in San Antonio
Hill Country Wound Care and Hyperbarics is a leading provider of treatment for delayed radiation injuries in San Antonio, Texas. Our board-certified physicians in Hyperbaric Medicine specialize in using Hyperbaric Oxygen Therapy (HBOT) to treat a range of late radiation effects, including osteoradionecrosis (ORN), soft tissue radionecrosis, radiation cystitis, and radiation proctitis. With three clinics equipped with hyperbaric chambers, we offer accessible, outpatient care for cancer survivors suffering from the long-term consequences of radiation therapy.
Understanding Delayed Radiation Injury
Radiation therapy, while effective at killing cancer cells, also damages surrounding healthy tissue by destroying small blood vessels. This creates a state of chronic hypoxia (low oxygen), preventing the tissue from healing, fighting infection, or recovering from subsequent surgery or trauma. These effects can manifest months, years, or even decades after treatment is complete. HBOT is the primary medical treatment that directly counteracts this process by stimulating angiogenesis (the growth of new blood vessels) in irradiated tissue.
Conditions Treated with HBOT
Our program treats all forms of delayed radiation injury, including: Osteoradionecrosis (ORN), particularly of the jaw (mandible) after head and neck cancer treatment; Soft Tissue Radionecrosis, causing non-healing wounds in the chest wall, pelvis, or extremities; Radiation Cystitis, leading to bladder bleeding (hematuria); and Radiation Proctitis, causing rectal bleeding and pain. HBOT is a UHMS and Medicare-approved indication for these conditions.
The HBOT Treatment Protocol
Patients undergo a series of treatments in a monoplace hyperbaric chamber, breathing 100% oxygen at 2.0 to 2.4 times normal atmospheric pressure for 90-120 minutes per session. A typical course for delayed radiation injury involves 30-40 sessions. This process supersaturates the blood plasma with oxygen, forcing it into the hypoxic irradiated tissues to stimulate new blood vessel growth, reduce inflammation, and restore healing capacity.
