Introduction To date, there is no evidence concerning the emergency surgical management of severe trauma patients (STP) with severe traumatic brain injury (STBI) presenting a life-threatening intracranial hematoma and a concomitant extra-cranial noncompressible active bleeding. Current guidelines recommend stopping the extra-cranial bleeding first. Nevertheless, the long-term outcome of STP with STBI mainly depends from intracranial lesions. Thus, we propose a combined damage-control surgical strategy aiming to reduce the time spent with intracranial hypertension and to hasten the admission in the intensive care unit. The main objective of the study is to evaluate the benefits of combined cranial and extra-cranial surgery of STP on the long-term outcome. Materials and Methods We retrospectively searched through the database of STBI of a level 1 trauma center facility (Sainte-Anne Military Teaching Hospital, Toulon, France) from 2007 until 2021 looking for patients who benefited from combined cranial and extra-cranial surgery in an acute setting. Results The research yielded 8 patients. The mean age was 35 years old (±14) and the male to female sex ratio was 1.7/1. The trauma mechanism was a fall in 50% of the cases and a traffic accident in 50% of the cases. The median Glasgow coma scale score was 8 (IQR 4) before intubation. The median Injury Severity Score was 41 (IQR 16). Seven patients (88%) presented hypovolemic shock upon admission. Six patients (75%) benefited from damage-control laparotomy among, whom 4 (67%) underwent hemostatic splenectomy. One patient benefited from drainage of tension pneumothorax, and one patient benefited from external fixator of multiple limb fractures. Seven patients (88%) benefited from decompressive craniectomy for acute subdural hematoma (5 patients) or major brain contusion (2 patients). One patient (12%) benefited from craniotomy for epidural hematoma. Three patients presented intraoperative profound hypovolemic shock. Six patients (75%) presented a favorable neurologic outcome with minor complications from extra-cranial surgeries and 2 patients died (25%). Conclusion Performing combined life-saving cranial and extra-cranial surgery is feasible and safe as long as the trauma teams are trained according to the principles of damage control. It may be beneficial for the neurologic prognostic of STP with STBI requiring cranial and extra-cranial surgery.
The Kernohan-Woltman notch phenomenon (KWNP) refers to an intracranial lesion causing massive side-to-side mass effect which leads to compression of the contralateral cerebral peduncle against the free edge of the cerebellar tentorium. Diagnosis is based on “paradoxical” motor deficit ipsilateral to the lesion associated with radiologic evidence of damage to the contralateral cerebral peduncle. To date, there is scarce evidence regarding KWNP associated neuroimaging patterns and motor function prognostic factors. A systematic review was conducted on Medline database from inception to July 2021 looking for English-language articles concerning KWNP, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The research yielded 45 articles for a total of 51 patients. The mean age was 40.7 years-old and the male/female sex ratio was 2/1. 63% of the patients (32/51) suffered from head trauma with a majority of acute subdural hematomas (57%, 29/51). 57% (29/51) of the patients were in the coma upon admission and 47% (24/51) presented pupil anomalies. KWNP presented the neuroimaging features of compression ischemic stroke located in the contralateral cerebral peduncle, with edema in the surrounding structures and sometimes compression stroke of the cerebral arteries passing nearby. 45% of the patients (23/51) presented a good motor functional outcome; nevertheless, no predisposing factor was identified. A Glasgow coma scale (GCS) of more than 3 showed a trend (p=0.1065) toward a better motor functional outcome. The KWNP is a regional compression syndrome oftentimes caused by sudden and massive uncal herniation and leading to contralateral cerebral peduncle ischemia. Even though patients suffering from KWNP usually present a good overall recovery, patients with a GCS of 3 may present a worse motor functional outcome. In order to better understand this syndrome, future studies will have to focus on more personalized criteria such as individual variation of tentorial notch width.
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.
