Operative Obstetrics

The ten years since the first edition of Operative Obstetrics have witnessed considerable changes in obstetric practice. There has been a continued increase in the rate of cesarean delivery, and the use of minimally-invasive surgery has rapidly gained popularity. Social changes affecting practice have also been significant, prompting a reevaluation of the appropriateness of certain types of operations during pregnancy. This fully-updated edition includes chapters on cesarean delivery, birth injury, ectopic pregnancy, and common surgical complications. It features a new discussion of surgical procedures performed by non-physicians and an updated treatment of fetal surgery. The text also considers complicated and controversial subjects such as cervical insufficiency,pregnancy termination, instrumental delivery, and shoulder dystocia. Each of the four sections includes an in-depth analysis of the important ethical and legal issues underlying practice for the area in question. An expanded appendix reviews legal concepts pertinent to practitioners in the field of obstetrics.

Watch an Angiogram Procedure

In this video, Dr. Mark A. Turco, Director of the Center for Cardiac and Vascular Research at Washington Adventist Hospital (Takoma Park, Maryland), performs an angiogram on a female patient with a history of heart disease in her family. Her stress test had indicated that she might have blockages in the blood vessels that carry blood to and from her heart. In his cath lab at Washington Adventist Hospital, Dr. Turco is able to see whether there are blockages and, if so, begin developing a treatment plan for her.

* E - epilepsy or exposure (heat stroke, hypothermia) or electrolytes
* I - insulin (diabetic emergency - high/low sugar)
* O - overdose or oxygen deficiency
* U - uremia (metabolic) or underdose

Schwannoma (Histology)

Notice the whirly swirly pattern and how the cell nuclei are closely bunched together... almost as if they're forming a fence (Verocay bodies). Schwannomas are benign spindle cell tumors that occur along the edges of peripheral nerves. They can usually be removed without damaging the nerve itself.
