Dear Colleagues,

The special issue of Clinical and Experimental Obstetrics & Gynecology “Obstetric Management of High-Risk Pregnancy” is a very important project. In obstetrics, emergent procedures are often required, and the ability to select the appropriate treatment has a direct influence on the prognosis of the mother and child.

At the time of emergent obstetric surgery, it is important to have mastered many surgical techniques. Therefore, it is necessary to acquire not only normal obstetric surgery techniques, but also the anatomical knowledge of the pelvic floor and the surgical techniques necessary for the treatment of uterine cancer and ovarian cancer. In addition, in patients who present with underlying diseases that require an emergency such as diabetic ketoacidosis, it is important to determine the diagnosis based on the characteristic symptoms, perform appropriate tests, and begin appropriate treatment as soon as possible. We hope that you will acquire new knowledge and techniques from this special issue.
