ABSTRACT

PURPOSE: Scaphocephaly is the premature closure of the sagittal suture. The treatment strategies mainly focus on correcting the shape of the head, but there are very limited studies examining changes in brain structure. This study aimed to investigate shape differences in the shape of corpus callosum regarding the pre-treatment and post-treatment term at scaphocephaly patients. METHODS: Cranium shape data were collected from the two-dimensional digital images. The generalized Procrustes analysis was used to obtain mean shapes in the pre- and postoperative phases. The shape deformation of the corpus callosum from the pre- to postoperative phases was evaluated using the thin plate spline method. RESULTS: There is an enlargement of the splenium part of corpus callosum in the late group. In the early group, corpus callosum genu and body enlargement were observed in the postoperative period compared to the preoperative period, followed by a narrowing of the isthmus region. CONCLUSION: This study showed structural deformations in the corpus callosum in scaphocephaly patients using head shape with the landmark-based geometric morphometric method by taking into consideration the topographic distribution. An enlargement at the splenium part of corpus callosum exposes after the cranial vault expansion depending on time.

ABSTRACT

BACKGROUND: Vascular injury complications during lumbar discectomy are rare but potentially life-threatening. Therefore, an early diagnosis and effective treatment management is required for these complications. CASE DESCRIPTION: A 50-year-old female patient was admitted to our outpatient clinic with severe back and right leg pain. She underwent surgery for right L4-5 extruded disc herniation with general anesthesia. Sudden arterial hemorrhage occurred during discectomy performed with straight disc forceps and was controlled using hemostatic materials, with no significant decrease in blood pressure. However, the patient became hypotensive near the end of the operation. The incision was quickly closed, and she was turned to supine position. Emergency abdominal ultrasound, computed tomography, and computed tomography angiography revealed an injury of the left main iliac artery, which was repaired by endovascular stenting. Laparotomy and Bogota bag were applied because of increased intrabdominal pressure at 3 hours postoperative. In addition, a retroperitoneal catheter was placed into the area of the right retroperitoneal hematoma on the first postoperative day. Tissue plasminogen activator was administered through the catheter. On postoperative day 3, the Bogota bag was removed, and the abdomen was closed. The patient was discharged without neurodeficit on day 27. Her abdominal fascial defect was closed with a synthetic graft after 5 months. CONCLUSIONS: Although lumbar discectomy is one of the most commonly performed neurosurgical procedures, the routine rules of discectomy should not be neglected. Early detection and a multidisciplinary approach can help prevent mortality in the event of vascular injury.
