Re-write this paragraph using medical terminology: The patient had trouble walking straight ever since his stroke. He could not pick up a fork to eat or tie his shoes, although he tried. The left side of his body was weak and he had difficulty with swallowing as well. He was evaluated by someone who studies movement and his treatment included exercises that should help restore his ability to do common tasks and strengthen his major muscles.

OPERATIVE REPORT
PREOPERATIVE DIAGNOSIS: Acute left subdural hematoma.
POSTOPERATIVE DIAGNOSIS: Acute left subdural hematoma.
PROCEDURE: Left frontotemporal parietal craniectomy with evacuation of massive subdural hematoma.
SURGEON: Sam Operator, M.D.
ANESTHESIA: General.
INDICATIONS AND CONSENT:
This is a 75-year-old white male who slipped and fell. He is on aspirin and Plavix. He has previously had a subdural hematoma 15 years ago from which he made a good survival. The indications, risks and complications of the procedure as well as alternatives were explained to the patient’s son, including risk of infection, bleeding, paralysis, loss of sensation, death and other complications, who requested the procedure be performed.
PROCEDURE:
With the patient under general endotracheal anesthesia, he was placed in the supine position with a large roll underneath the left shoulder, thus turning him to the right, and using the horseshoe head rest with adequate padding to all pressure points. He was then prepped and draped in usual meticulous manner. A linear incision was performed from the temporal to the parietal region on the left. Sharp dissection was carried through the skin and the scalp was reflected. There was evidence of a previous cranioplasty here. The cranioplasty had been fractured and had been depressed down anteriorly. A craniectomy was then performed around the cranioplasty. The cranioplasty was removed. There was a large subdural hematoma. As soon as the subdural hematoma was removed from the parietal region, there was massive brain swelling. There was an evident laceration of the left middle cerebral vein anteriorly, which had been caused by the sharp edge of the acrylic cranioplasty. Old subdural hematoma was removed. However, because of the massive swelling, the bone could not be replaced. Hemostasis was achieved by Gelfoam. Dura could not be closed and was laid over the brain as far as possible. The brain was covered with Gelfoam. A drain was placed and brought out through a separate stab incision. The wound was then closed by means of 2-0 Vicryl on galea and muscle and 3-0 nylon on the skin. The patient tolerated the procedure well. All sponge and needle counts were correct. Estimated blood loss was about 300 mL. He will be returned to Intensive Care for further care.
QUESTIONS (answer in PLAIN ENGLISH – as if addressing a layperson who does not know medical language):
Why did the patient need this operation?
What operation did the patient have in the past?
What exactly was this operation?
What did the surgeon find when he got to the area of concern?
What was found in the left middle cerebral vein?
What complications arose when the surgeon attempted to put things back in place before closing the wound?
