Defined in the last decade, erector spinae plane block (ESPB) is one of the more frequently used interfacial plans, and it has been the most discussed block among the recently defined techniques. Lumbar ESPB administered at lumbar levels is relatively novel and is a new horizon for regional anesthesia and pain practice. In this article, we aim to explain and introduce different approaches and explain the possible mechanism of action of lumbar ESPB. The objective of this review is to analyze the case reports, clinical and cadaveric studies about lumbar ESPB that have been published to date. We performed a search in “Pubmed” and “Google Scholar” database. After a selection of the relevant studies, 59 articles were found eligible and were included in this review. While we believe that lumbar ESPB is reliable and easy, we suggest that its efficacy and indications should be verified with anatomical and clinical studies, and its safety should be confirmed with pharmacokinetic studies. Moreover, the possibility of complications must be considered.

VARICOSE VEINS are dilated and twisted veins that often are located in the lower extremities. Conservative or interventional methods are used in the treatment of varicose veins. The main interventional methods are laser or thermal ablation, sclerotherapy, and surgery.¹ x 1 Raetz, J.M., Wilson, M., and Collins, K. Varicose veins: Diagnosis and treatment. Am Fam Physician. 2019; 99: 682–688 Google Scholar See all References Although new treatment modalities are alternative to surgery, ligation and stripping surgery remain the standard treatment, especially for complicated varicose veins. Some of these procedures can be performed with the patient under general or regional anesthesia. Recently, with the use of ultrasound in clinical anesthesia practice, plane blocks have started to replace neuroaxial anesthesia techniques in many surgical fields.² x 2 Ciftci, B., Ekinci, M., Celik, E.C. et al.
