Long-Term Sensory Function 3 years after Minimally Invasive Repair of Pectus Excavatum with Cryoablation

Who's speaking

• Kim Priven — guest

Chapters

• 0:00Introduction and Context — Introduction to the topic of long-term effects of cryoablation in minimally invasive pectus excavatum repair, noting known short-term benefits.
• 0:17Study Design and Methods — Description of the single-institution prospective cohort study design, patient population, and assessment methods for sensory function and neuropathic pain.
• 0:44Results and Conclusions — Presentation of hypoesthesia and neuropathic pain findings, with conclusion that sensory deficits are common but clinically significant pain is rare.
