<b><i>Introduction:</i></b> Posthemorrhagic hydrocephalus in preterm infants is a serious entity related to high mortality and morbidity. Neuroendoscopic lavage (NEL) is a suitable alternative for the management of this pathology. However, as with every endoscopic technique, it requires some experience and several cases to master. <b><i>Methods:</i></b> We present a descriptive study of some technical nuances, tips, and tricks that have been learned in the last 8 years with over a hundred NELs performed in preterm infants. These variations are classified into 3 categories according to their temporal relationship with the surgical procedure: preoperative stage, intraoperative stage, and postoperative stage. We include a brief description of each one and the reasons why they are included in our current clinical practice. <b><i>Results:</i></b> Twenty tips and pearls were described in detail and are reported here. Preoperative, intraoperative, and postoperative variations were exposed and related to the most frequent complications of this procedure: infection, cerebrospinal fluid leak, and rebleeding. <b><i>Conclusions:</i></b> NEL is a useful technique for the management of germinal matrix hemorrhage in preterm infants. These technical nuances have improved the results of our technique and helped us to prevent complications related to the procedure.
Split cord malformation (SCM) is a term used for all double spinal cords. It represents 3.8%–5% of spinal dysraphisms. Pang et al.’s embryological theory proposes the formation of an “accessory neurenteric canal” that communicates with the yolk sac and amnion. To the authors’ knowledge, only three cases of diastematobulbia (basicranial SCM) associated with a spur or dermoid have been reported in the literature.The case patient is a newborn girl with an occipitocervical meningocele and dermal sinus associated with an anomaly of notochordal development in the transition between the medulla oblongata and the spinal cord (diastematobulbia) without a bony septum or dermoid cyst. The patient also has agenesis of the atlas and an absence of corticospinal tract decussation. This patient underwent reconstruction of the occipital meningocele and dermal sinus excision.To the authors’ knowledge, this is the first described case of type II diastematobulbia (basicranial SCM), without a dermoid cyst. The authors analyzed the embryological errors present in the case patient and considered the option of further surgical treatment depending on the evolution of the patient’s condition. At the time of this report, the patient had shown normal psychomotor development. However, this fact may only be due to the patient’s young age. Considering that after initial untethering the patient remained clinically asymptomatic, conservative and close surveillance has been and continues to be the proposed treatment.
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.
