Overall, we favor a tailored posterior fossa craniectomy with dural scoring as the initial surgical procedure in children with Chiari I malformation with or without a syrinx. This less invasive approach minimizes complications associated with dural opening and offers comparable success rates.
The use of an SCM flap for the repair of esophageal injury, in the setting of anterior cervical spine surgery, is a safe and effective tool. An SCM flap appeared to improve the time in initiating oral intake without any significant morbidity.
Clinical findings seem to confirm an apparent predilection of astroblastomas for younger children (median age of onset, 5 years) and the existence of two prognostically different types of tumor-well differentiated (low grade) and anaplastic (high grade). Microscopic findings suggest a closer resemblance of tumor cells to astroblasts rather than to "tanycytes" or ependymal cells. It seems, however, that anaplastic astroblasts have a tendency to evolve toward, or be associated with, less differentiated cells, either neuroepithelial or sarcomatous.
A careful patient selection and preoperative planning lead to better results of ETV. A higher early and late complication rate in children younger than 1-year-old were noted in our series. There is definitely a learning curve for this technique, and several technical considerations are helpful to avoid adverse events. Most of the early complications are transient, while potential devastating injuries can occur. Long-term follow-up is needed to identify delayed closure of the fenestration. Ventricular access devise is helpful for diagnostic and therapeutic purposes during the follow-up.
Ticagrelor offers an effective alternative to clopidogrel non-responders. All of our patients showed immediate platelet inhibition after a loading dose of 180 mg of ticagrelor, with no adverse effects. The cost of medication, patient compliance (twice a day doses), and reversible inhibition should be taken into consideration when using ticagrelor.
Pediatric intracranial aneurysms are exceedingly rare and account for less than 5% of all intracranial aneurysms. Open surgery to treat such aneurysms has been shown to be more durable than endovascular techniques, and durability of treatment is particularly important in the pediatric population. Over the past 2 decades, however, a marked shift in aneurysm treatment from open surgery toward endovascular procedures has occurred for adults.The authors describe their early experience in treating 3 unruptured pediatric brain aneurysms using the Pipeline embolization device (PED). The first patient, a girl with Majewski osteodysplastic primordial dwarfism Type II who was harboring multiple intracranial aneurysms, underwent two flow diversion procedures for a vertebrobasilar aneurysm and a supraclinoid internal carotid artery aneurysm. The second patient underwent PED placement on a previously coiled but enlarging posterior communicating artery aneurysm. All procedures were uneventful, with no postsurgical complications, and led to complete angiographic obliteration of the aneurysms. To the authors' knowledge, this is the first series of flow diversion procedures in children reported in the medical literature.While flow diversion is a new and relatively untested technology in children, outcomes in adults have been promising. For challenging lesions in the pediatric population, flow diversion may have a valuable role as a well-tolerated, safe treatment with durable results. Many issues remain to be addressed, such as the durability of flow diverters over a very long follow-up and vessel response to growth in the presence of an endoluminal device.
Objective: To analyze our institution’s work-up for patients with a diagnosis of subdural haematoma (SDH) in order to determine how many of them are secondary to child abuse, as well as to examine their final functional outcome. Methods: Retrospective review of children under 2 years of age diagnosed as having SDH between 1995 and 2005. Results: A total of 35 cases were identified. Fifteen patients that had underlying conditions that predispose them to bleed were excluded. Among the remaining 20 patients, seizures and head trauma were the main causes for consultation. All patients had a coagulation study and a head computed tomography carried out, 11 of these had a magnetic resonance imaging and 1 had a post-mortem examination. Bilateral SDHs in different stages of evolution was the most common pattern of intracranial haemorrhage. Fourteen infants had a skeletal survey, 4 had a bone scintigraphy and 19 had an ophthalmoscopic examination. Fractures were diagnosed in 7 patients and retinal haemorrhages in 11. The final diagnoses were: 10 shaken baby syndromes, 4 idiopathic SDH, 3 strokes, 2 coagulopathies and 1 accidental head injury. Upon follow-up, 1 patient had died and 9 had sustained permanent disabilities. Conclusions: Cases of infantile SDH are usually thoroughly investigated. In spite of this, sometimes it is not possible to determine the SDH aetiology. Nonetheless, shaken baby syndrome remains the most frequent cause of SDH in infants, and it carries a poor prognosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
