Although both the groups have few degrees of risks and complications, these are not major one and can be managed easily. The fusion rates are similar in both the groups (PLF and PLIF). Quality of life index showed significant difference within 1 week, after 3 months, and after 6 months of surgery in all of our patients. We concluded from our study and after the review of literature that the patients with lumbar DDD should undergo spinal instrumentation surgery either PLF or PLIF as per the requirement as these surgeries provide good clinical and radiological outcomes in terms of pain, disability index, LLA, and maintenance of DSH. Although both the groups have few degrees of risks and complications, these are not major one and can be managed easily. The fusion rates are similar in both the groups (PLF and PLIF). Quality of life index showed significant difference within 1 week, after 3 months, and after 6 months of surgery in all of our patients. Extracranial-intracranial (EC-IC) arterial bypass has been used in the treatment of various cerebrovascular ischemic disease due to atherosclerosis or Moyamoya disease, skull base tumors encasing large IC artery or complex IC aneurysms. The aim is to analyze surgical technique (EC-IC bypass) and its outcome with intraoperative use of dual image video angiography (DIVA) and Doppler ultrasound. We studied in this article a series of 23 patients operated in Banbuntane Hotokukai Hospital, Fujita Health University, for which a superficial temporal artery-middle cerebral artery anastomosis was done for steno-occlusive disease, giant IC aneurysm or Moyamoya disease. The study was conducted between 2018 and 2020. We used dual-image video angiography (DIVA) and Doppler ultrasound to assess the luminal patency of anastomosis during the procedure. In this study, three patients presented with Moyamoya disease, 4 had aneurysm, whereas
