“…These changes are associated with increases in intracranial pressure (ICP), which will reduce cerebral perfusion pressure, eventually reducing cerebral blood flow [1]. The mass effect can be exacerbated by tumour-associated cerebral oedema or by occlusion of ventricular CSF flow leading to a "trapped ventricle" [15]. Identifying secondary hydrocephalus is of prime importance since it can lead to acute deterioration of consciousness level, which drainage procedures can treat.…”

In the comatose patient, urgent diagnosis can be a critical priority if appropriate interventions are going to be performed promptly. In many cases, imaging investigations will form a core component of this assessment. In others, where clinical criteria allow confident diagnosis, imaging may still be of significant benefit in providing confirmatory information and may also provide clinically useful prognostic data. In the critically ill comatose patient, confirmation of a diagnosis of brain death may be required. Although this diagnosis is based on clinical criteria, imaging has long been used to provide adjunct supportive information. In recent years, there has been an increased interest in the use of imaging to support a diagnosis of brain death as functional imaging modalities have improved. In this chapter, we will initially review the role of imaging in supporting diagnosis and prognostication in patients suffering from coma. We will discuss the optimal imaging strategies, specific disorders, and specific imaging findings which might help with differential diagnosis and prognostication. We will then discuss the role of imaging in supporting the diagnosis of brain death.

Refined Temporal-to-Frontal Horn Shunt for Treatment of Trapped Temporal Horn After Surgery of Peri- or Intraventricular Tumor: A Case Series Study

et al. 2021

BackgroundTrapped temporal horn (TTH) is a localized hydrocephalus that can be treated with cerebrospinal fluid diversion. Refined temporal-to-frontal horn shunt (RTFHS) through the parieto-occipital approach is rarely reported in the literature and its effectiveness remains unclear. The aim of the present study is to investigate the efficacy and outcome of RTFHS for treatment of TTH.Materials and MethodsWe consecutively enrolled 10 patients who underwent RTFHS for TTH after surgical resection of peri- or intraventricular tumors from February 2018 to March 2021. Clinical, radiological, and follow-up data were collected and analyzed. The most common underlying pathology was meningioma (n=4), followed by central neurocytoma (n=3), thalamic glioblastoma (n=2), and anaplastic ependymoma (n=1).ResultsThe mean Karnofsky performance scale (KPS) score and TTH volume at onset were 54.0 ± 15.1 (range 40-80) and 71.3 ± 33.2cm3 (range 31.7-118.6cm3), respectively. All patients (10/10, 100.0%) presented with periventricular brain edema (PVBE), while midline shift was observed in 9 patients (9/10, 90.0%). RTFHSs were implanted using valveless shunting catheters. No patients developed acute intracranial hemorrhage or new neurological deficit postoperatively. During the follow-up of 17.2 ± 13.7 months (range 3-39 months), all patients showed clinical and radiological improvement. The mean KPS score at the last follow-up was significantly increased to 88.0 ± 10.3 (range 70-100, p<0.0001). RTFHS resulted in significant complete remission in PVBE and midline shift in 8 (80.0%, p=0.0007) and 9 (100.0%, p=0.0001) patients, respectively. As the postoperative follow-up duration prolonged, the mean TTH volume decreased in a consistent, linear trend (p<0.0001). At last follow-up, the mean TTH volume was significantly reduced to 15.4 ± 11.5 cm3 (range 5.6-44.1 cm3, p=0.0003), resulting in a mean relative reduction of 77.2 ± 13.1% compared with the volume of TTH at onset. Over drainage was not observed during the follow-up. No patient suffered from proximal or distal shunt obstruction or shunt related infection, and the revision rate was 0%.ConclusionRTFHS seems to be safe and effective for the treatment of TTH with favorable outcomes. Advantages of this technique could be technically less complex and invasive, cost-effective, avoidance of various intraperitoneal complications, and maintaining a near-physiological CSF pathway.
