Daniel T. DeArmond, MD

Assistant Professor and Associate Program Director for Thoracic Surgery Residency

Dr. DeArmond completed general surgery residency at the University of Texas Health Science Center at San Antonio and cardiothoracic surgery residency at the University of Iowa. He is board certified by the American Board of Thoracic Surgery and the American Board of Surgery. He completed an additional year of fellowship training in general thoracic surgery at Cedars-Sinai Medical Center in Los Angeles, CA, where he was exposed to a high-volume experience with video-assisted thoracic surgery (VATS) and thoracic endoscopy. His clinical specialty is the application of VATS to operations for lung cancer, where the advantage to patients is a complete cancer operation with less pain, shorter hospital stays, and a shorter recovery period. During his surgical training he spent three years in the lab researching the molecular mechanisms of cancer, which has allowed him to publish and present at numerous national meetings. He is interested in developing novel medical devices and drug therapies related to thoracic surgery.

Breathing Easier: Surgical Options in Lung Cancer

When lung cancer patients come to see Daniel DeArmond, M.D., they often feel that life is over, but DeArmond said there are options that many people don’t know. Dr. DeArmond will discuss lung cancer and its surgical treatment at the Nov. 10 free public lecture at the Cancer Therapy & Research Center at The University of Texas Health Science Center at San Antonio.

'Five Minutes with Daniel DeArmond, MD' — Minimally Invasive VATS Lobectomy: The San Antonio Business Journal conducts a conversation with Dr. Daniel DeArmond, Assistant Professosr of Cardiothoracic Surgery, who has extensive training and expertise in a novel procedure known as VATS – Video Assisted Thoracic Surgery – which is used to remove cancerous lobes from the lungs. Since joining our faculty in 2007, Dr. DeArmond has performed approximately 80 VATS lobectomies. "We are the only program in this region doing this operation with the commitment of a surgeon who has specific, minimally-invasive thoracic surgery fellowship training," says Dr. DeArmond.

Cardiothoracic surgeons V. Seenu Reddy, MD, MBA, and Daniel T. DeArmond, MD, are interviewed by the San Antonio Express-News regarding the impact of a depressed economy on the health and healthcare of South Texas pulmonary and cardiac patients. Both the intensity of stress and the effect of stress on our bodies are potentially harmful for some post-surgical patients. Express-News story (3-19-09)

Use of robotic surgery expanded to early-stage lung cancer: In mid-October, Daniel DeArmond, M.D., assistant professor of surgery, removed the lobe of a patient’s lung by making small incisions in the chest and inserting miniature instruments that he maneuvered remotely, using handles and pedals from a console six feet away.

Dan DeArmond, MD, Cardiothoracic Surgery, explains precision robotic lung cancer surgery options: Patients whose lung cancer has been caught very early now have a minimally invasive surgical option at Christus Santa Rosa Northwest — da Vinci® robotic surgery. Using the da Vinci robotic system, Dr. DeArmond is able to perform lung tissue resections with minimal incisions, greatly reducing the patient's recovery and in-patient days. "If this tool can help us to move that frontier forward, then it's an advantage to patients," says Dr. DeArmond. This surgery is not for all lung cancer patients, but for those whose disease has been caught soon enough, long-term survival rates are a very encouraging 80%. | Physician Referrals: 210-358-4579 (10-16-08)

Less invasive procedure to treat lung cancer: Dan DeArmond, MD, Cardiothoracic Surgery, discusses video-assisted thoracic surgery (VATS) on KENS-12. VATS is a less-invasive alternative to traditional rib-spreading surgery for lung cancer. KSAT-12 (4-03-08)

HSC News - Minimally invasive surgery a new option for lung cancer (3-28-08)

New lung cancer procedure is less invasive: A new surgical procedure for early-stage lung cancer is helping patients recover more quickly and without as much pain as the traditional operation. Daniel DeArmond, MD, Cardiothoracic Surgery, is one of only a very small number of thoracic surgeons in San Antonio who is performing the new video-assisted thoracic surgery procedure (VATS).
