A 19-year-old Chinese man involved in a motor vehicle accident was admitted to the emergency department presenting with a Glasgow Coma Scale (GCS) of 3 and right eye mydriasis. A computed tomography (CT) scan of his brain revealed right-side ASDH and a midline shift of 14.5 mm with severe brain swelling (Figs. and ). He was hemodynamically stable, with no clotting dysfunction according laboratory tests. He was subsequently transferred to the operating room and underwent a right decompressive craniectomy. The ASDH was caused by a ruptured lateral fissure vein. The brain exhibited slowly progressing swelling after the hematoma and inactivated brain tissue were evacuated. Consequently, immediate augmentation duraplasty using artificial dura mater was performed. On examination, the patient exhibited bilateral mydriasis. Given the slowly progressing brain swelling, this was possibly due to delayed contralateral ASDH or EDH. A CT scan of the brain was performed immediately thereafter, which revealed the emergence of contralateral DEH (Fig. ). Owing to a mass effect from the DEH and severe brain swelling, the patient was immediately taken to the operating room to undergo a left hematoma evacuation and decompressive craniectomy. During surgery, it was determined that the DEH was caused by the rupture of the middle meningeal artery branch, with temporal and occipital bone fractures (Fig. ). Following surgery, the patient was transferred to the neurological intensive care unit, where the left and right pupil sizes were measured to be 2.0 mm and 5.0 mm, respectively.\nOn postoperative day 1, approximately 5 h after the second surgery, the primary nurse found that the size of the patient’s left pupil gradually increased from 2.0 mm to 3.5 mm. An immediate brain CT scan revealed evidence of left-side DEH of the posterior cranial fossa (Fig. ). Owing to mass effect of the DEH, a third surgery was offered. He underwent left posterior cranial fossa hematoma evacuation and decompressive craniectomy. During the third surgery, it was determined that the DEH was caused by a ruptured transverse sinus. A brain CT following the third surgery was performed (Fig. ). The patient recovered to a GCS of 7 within 40 days after surgery, and was transferred to the rehabilitation hospital. He was ultimately discharged from the rehabilitation hospital with a Glasgow Outcome Score of 4. He underwent cranioplasty 1 year later and has since recovered well.
A 28-year-old right-handed male with trauma signs on his head (a wound in his occipital region, nasal hemoliquorrhea, right-sided otohemoliquorrhea) was admitted to Yalta City Hospital after he felt down while riding a skateboard. On admission, he was Glasgow coma scale (GCS) 5 with left dilated pupil.\nCT scans showed intracerebral traumatic hematoma in the left frontal lobe, 6 mm midline shift, right temporal bone fracture and a small pneumocephalus in sellar region [].\nPerformed operation: left-sided hemicraniectomy through “trauma-flap” incision, evacuation of traumatic intracerebral hematoma in left frontal lobe. Intraoperatively an acute brain swelling occurred. Patient was transferred to ICU after the operation. One day after the operation, right-sided anisocoria occurred and a contralateral EDH with 10 mm of midline shifting was found at the control CT scans [].\nPatient underwent decompressive craniectomy in the right temporo-parietal region and evacuation of EDH about 100 cc in volume.\nOne day later there were no signs of residual hematoma on CT scans [].\nAt the fifth day after the operation, percutaneous tracheostomy was performed. Patient was comatose 19 days after admitting to the hospital. He underwent conservative treatment of brain edema. After that control CT scans were performed [].\nNext day patient became apallic and 7 days later akinetic mutism was found.\nAt the 32nd day in the hospital, he was transferred from the intensive care unit (ICU) into the neurosurgical department.\nOne month later patient was awake and spoke with single separated words.\nOn 76th day in the hospital the CT scans were performed with 1 mm collimation for the titanium mesh implants and stereolithographic models development [].\nAt his 2 month follow-up, he had neurological deficit of left-sided spastic hemiparesis, anosognosia, right-sided convergent strabismus.\nBilateral cranioplasty of two huge bone defects [Figures and ] with individually constructed titanium mesh was performed.\nPostoperative period was uneventful and in 15 days patient was sent to rehabilitation.\nCT scans in a month after the cranioplasty showed brain expansion to its original shape [].
