Rapid detection of recurrent intraventricular hemorrhage by ultrasound in a multiple trauma patient who had undergone craniectomy
Critical Care volume 16, Article number: 459 (2012)
Ultrasound may be a useful tool to evaluate intracranial abnormalities in critically ill patients undergoing decompressive craniectomy. We present a multiple trauma patient who had undergone craniectomy and in whom recurrent intraventricular hemorrhage and patterns of cerebral blood flow were rapidly detected by ultrasound.
Ultrasound has been widely used for rapid assessment of critical illness and is regarded as a visual stethoscope. There are few reports on the diagnosis of intracranial lesions by ultrasound in ICU patients. Here we present a multiple trauma patient who had undergone craniectomy and in whom recurrent intraventricular hemorrhage was rapidly detected by ultrasound.
A 29-year-old man was transferred from a local hospital 9 hours after a 5-meter fall. His Glascow Coma Score (GCS) was 4 and both pupils were unequal in size. The diagnosis was severe cerebral contusion and subdural hemotoma in the left temporal and parietal lobe, bilateral lung contusion and left clavicle fracture. He received an urgent decompressive craniectomy and evacuation of hematoma, and was then admitted to the emergency ICU. In the following days, his condition improved and his GCS reached 8, although this suddenly decreased to 6 on day 12. Bedside ultrasound was performed instantly and showed acute intraventricular hemorrhage (IVH), which was confirmed by subsequent computed tomography (CT) (Figure 1). Urgent bilateral ventricular external drainage was performed and his condition improved. Lumbar cistern tube drainage was performed on day 19. Unfortunately, he suddenly developed dilated pupils on day 20. Bedside ultrasound and a head CT scan were arranged immediately, both showing recurrence of IVH (Figure 1). The family refused further treatment and he then became brain dead (Figure 1).
Ultrasound is a useful tool to evaluate intracranial abnormalities in patients undergoing decompressive craniectomy. The absence of the skull may facilitate the ultrasound to detect the brain, and intracranial morphological abnormal signs such as dislocation of the midline, intracerebral hematomas, size of lateral ventricular and hydrocephalus may be clearly displayed on the screen [1, 2]. This rapid and non-invasive method can complement the results of CT and may help to reduce delays in surgical management. Caricato and colleagues  found that ultrasound in patients with decompressive craniectomy was as effective as CT to evaluate intracerebral disorders. In this multiple trauma patient, IVH happened twice after the craniectomy and was immediately identified by ultrasound. Meanwhile, ultrasound may detect the characteristics of cerebral blood flow, which helps to assess intracranial pressure and cerebral perfusion pressure [4, 5]. This highlights the special value of transcranial ultrasound in critically ill patients with craniectomy.
