Video assisted thoracoscopy (VATS) is a frequently used method for both therapeutic and diagnostic purposes. VATS is usually performed under general anesthesia however, paravertebral block or other regional techniques could be used as an option in selected patients undergoing thoracoscopic diagnostic biopsy. In this case presentation, we present the application of ultrasound guided erector spinae block (ESPB) for the management of a VATS case as a main anesthesia method in a 58 years old male patient.  ESPB at level of T5 was applied  under sedoanalgesia anda mixture of local anesthetics was applied between transverse process and erector spinae muscle. The sensorial block between T2-T7 dermatomes was confirmed after 30 minutes following block  application. Sampling of deep dermal and subcutaneous surgical tissue biopsies, dissection of   lung parenchyma and thoracic wall were successfully completed . Total dose of  30 mg intravenous ketamine was applied
during the surgery.  ESPB may be used for anesthesia in suitable diagnostic VAS cases.
