Micro invasive MRI- and CT-scopic treatments for common diseases like back pain, disk prolapse, tumors or arterial occlusive diseases with endoscopes, lasers or micro mechanical instruments as well as drug instillations like ethanol-ablation techniques are routinely performed in our interventional center. Lasers are used for tumor ablation or hyperthermia and in combination with endoscopes for diskectomies. Percutaneous Ethanol Instillation (micro-PEI) is performed for palliative treatment of tumor pain and cancer therapy and also for therapy of low back pain-facet-joint denervations under local anesthesia. Also sympathectomies for pain of herpes zoster or osteoporosis and arterial occlusive diseases are realized with ethanol. Cortisone is high precisely instillated for chronical back pain or neuralgias.
