BACKGROUND: Cranioplasty is aimed to restore the structure and function of the lost portion of the skull defect. Many materials can be used for cranioplasty, such as the bones of the patient (autograft), the bones of other patients (allograft), bones of animals (xenograft), or synthetic materials such as acrylic or titanium mesh. These materials are quite expensive and sometimes require complex processes. Manual shaping of material for cranioplasty is also quite time-consuming and prone to cause esthetic dissatisfaction. The author will discuss the case of using polylactic acid (PLA) implant with 3-dimensional (3D) printing customization as a cheap and accurate cosmetic solution for cranioplasty procedures. CASE REPORT: We report 2 cases of skull defect underwent cranioplasty. The first case, female, 20-year-old, had a history of severe traumatic brain injury (TBI) and epidural hematoma. She underwent decompression craniotomy on the left frontotemporoparietal region of her skull. The second case, male, 46-year-old, had a history of spontaneous intracerebral hemorrhage due to arteriovenous malformation (AVM). He underwent decompression craniotomy on the right frontotemporoparietal region of her skull. Both the data of computerized tomography (CT) scan were reconstructed to get 3D model of skull defect. Prosthesis was made by 3D printer accordingly using PLA as material. There was no complication reported postoperatively and cosmetic satisfaction was obtained on both cases. CONCLUSION: The use of PLA implant with 3D printing customization was proved to be cost-effective and good cosmetic satisfaction with no complication reported following cranioplasty procedure.

Introduction: Brain arteriovenous malformation (AVM) is a congenital vascular lesion in which arterial blood flows directly into draining veins without capillary networking. The estimated incidence rate is approximately 1 case for 100,000 people a year. Clinical presentations are headache, seizure, neurological deficit, and others that are caused by space-occupying lesions. The treatment of brain AVM consists of microsurgery resection, embolization, stereotactic radiosurgery to conservative treatment. Methods: The design of the study was a descriptive non-analytical study. Data were taken from patients' medical records, radiological records, and catheter lab data records at National Brain Center Hospital in 2015 -2016. Results: There were 32 patients with AVM. The characteristics of brain AVM in our study were mostly men (62.5%), productive age ranging from 20 -29 years (31.25%), manifested as seizure (43.75%), presence with Glasgow Coma Scale (GCS) score 15 (87.5%), and rupture of brain AVM nidus (59.38%). Conclusion: Brain AVM predominantly occurred at a young age and the management varied on the Spetzler-Martin grading. In addition, the likelihood of rupture was influenced by the characteristics of the lesion, such as size, age, location of the nidus, and history of rupture of brain AVM nidus.

Background: The maternal deaths due to obstetrical cases declined, but the maternal deaths that caused by nonobstetrical cases still increase. The study reported that traumatic cases in pregnancy are the highest causes of mortality in pregnancy (nonobstetrical cases) in the United States. Another study reported that 1 in 12 pregnant women that experienced traumatic accident and as many as 9.1% of the trauma cases were caused by traumatic brain injury (TBI). The female sex hormone has an important role that regulates the hemodynamic condition. Anatomical and physiological changes during pregnancy make the examination, diagnosis, and treatment of TBI different from non-pregnant cases. Therefore, it is very important to lead the algorithm for each institution based on their own resources. Case Series: A 37-year-old woman with a history of loss of consciousness after traffic accident. She rode a motorbike then hit the car. She was referred at 18 weeks' gestation. Glasgow Coma Scale (GCS) E 1 V 1 M 4 , isochoric of the pupil, reactive to the light reflex, and right-sided hemiparesis. The non-contrast head computed tomography (CT) scan revealed subdural hematoma (SDH) in the left frontal-temporal-parietal region, SDH of the tentorial region, burst lobe intracerebral hemorrhage, and cerebral edema. There was not a fetal distress condition. The next case, a 31 years old woman, in 26 weeks gestation, had a history of unconscious after motorcycle accident then she fell from the height down to the field about 3 m. GCS E 1 V 1 M 3 , isochoric of the pupil, but the pupil reflex decreased. Noncontrast CT scan revealed multiple contusion, subarachnoid hemorrhage, and cerebral edema. She had a good fetal condition. Discussion: We proposed the algorithm of TBI in pregnancy that we already used in our hospital. The main principle of the initial management must be resuscitating the mother and that also the maternal resuscitation. The primary and secondary survey is always prominent of the initial treatment. Conclusion: The clinical decision depends on the condition of the fetal, the surgical lesion of the intracranial, and also the resources of the neonatal intensive care unit in our hospital.
