This is a confirmed case of scar ectopic pregnancy. Yesterday, I carried out this exam in an emergency room, without much time to perform an adequate sonogram, the patient did not feel good with “cramps” but no signs of bleeding.

Although ultrasounds are relatively safe and have become integral tools in medicine, the underlying thermal and mechanical mechanisms have the potential for causing negative biological effects. To protect patients, the National Electrical Manufacturers Association developed standards requiring the on-screen display of thermal indexes (TI) and mechanical indexes (MI) on machines capable of producing MIs or TIs greater than 1.
