Arteriovenous malformations (AVMs) are complex and rare cerebral vascular dysplasia. The main purpose of treatment is to avoid the neurological impairment caused by hemorrhagic stroke. The Spetzler-Martin (SM) grading system is widely used to estimate the risk of postoperative complication based on maximum AVM nidus diameter, pattern of venous drainage, and eloquence of location. Generally, grade I and II are amenable to surgical resection alone. Grade III is typically treated via a multimodal approach, including microsurgical resection, embolization, and radiosurgery (SRS). Grade IV and V are generally observed unless ruptured. However, some previous studies indicated that despite the high rate of poor outcomes for high-level unruptured AVMs, the mortality for high-level unruptured AVMs are likely lower than untreated patients. With the development of new embolic materials and new intervention strategies, patients with high-level AVMs may have more opportunities to underwent more aggressive interventions. The OHAVM study aims to clarify the clinical outcomes for patients with SM grade IV and V AVMs after different management strategies.

Postoperative analgesia management in inguinal hernia surgery is difficult because of the content of the surgical procedure. A multimodal approach to postoperative analgesia has recently been proposed. For this reason, various methods are used.Regional blocks, pharmacological treatments are among these methods. Among the regional blocks, ilioinguinal and hypogastric blocks are used more safely and with increasing frequency, especially with the introduction of ultrasonography in the clinic.Forero et al. firstly, erector spinae block which was used for the first time in the treatment of thoracic neuropathic pain has been widely used especially in laparoscopic abdominal surgery and it has taken its place in the literature. It is performed at T4-5 level in breast and thoracic surgery and T7 level in abdominal surgery. In this block, local anesthesia between the erector spina muscle and the transverse protrusion of the vertebra was used to create analgesia in the anterior abdominal wall. In this study, we planned to investigate degree of postoperative pain, sensory block levels, analgesic consumption, propofol-remifentanyle consumption and side effects of patients undergoing inguinal hernia surgery under general anesthesia with erector spinae block.
