Season 7, Episode 18

Also known as: Brain bleed

Callie sustains a large epidural and subdural hematoma after going through a windshield in a car accident. Derek performs emergency craniotomy to evacuate the hematoma and decompress her brain.

Also known as: Brain bleed

Found concurrently with the epidural hematoma on CT scan, requiring surgical decompression. There is concern she may not regain full neurological function.

Also known as: Hole in the heart

Traumatic VSD from blunt chest trauma. Initially planned for open repair with bypass, but Cristina convinces Owen to perform a percutaneous catheter-based repair to avoid heparin and hypothermia risks to the baby.

Also known as: Internal bleeding

Callie has significant intra-abdominal bleeding requiring damage control surgery with temporary abdominal closure. She later develops abdominal compartment syndrome requiring re-operation.

Also known as: Collapsed lung

Teddy identifies no breath sounds on the right side and places a chest tube to treat the pneumothorax from the trauma.

Also known as: V-fib

During initial trauma resuscitation, Callie goes into ventricular fibrillation and requires defibrillation and CPR before being stabilized.

Also known as: Cold exposure

Callie develops hypothermia during surgery (temp drops to 32 degrees), requiring warm fluids and affecting her clotting ability.

Also known as: Early labor

Callie begins having contractions during surgery at 23 weeks gestation, creating conflict about whether to deliver the barely viable baby versus continuing to treat Callie's injuries.

Also known as: Premature birth

Baby delivered at 23 weeks weighing 1 pound 1 ounce after Callie codes during surgery. Initial Apgar is zero, requiring resuscitation, intubation, and intensive support.

Also known as: Pressure buildup in the belly

Callie develops abdominal compartment syndrome with a tight, distended abdomen and flash pulmonary edema, requiring emergency return to the OR.

Also known as: Fluid in the lungs

Flash pulmonary edema develops secondary to abdominal compartment syndrome and cardiovascular compromise.

Also known as: SVT

Callie develops SVT requiring treatment with adenosine and diltiazem.

Also known as: Air bubbles in blood vessels

During the percutaneous VSD repair, Callie develops what is suspected to be an air embolus, causing severe bradycardia and requiring cardiac massage and resuscitation.
