Screw fixation without fusion for low lumbar chance fracture accompanied by spinal epidural hematoma in patient with ankylosing spondylitis.

Ankylosing spondylitis (AS) is a chronic inflammatory disease involving the sacroiliac joint and axial spine. AS may render the ankylosed spine prone to trauma and cause an increased frequency of associated epidural hematomas in spine fractures. Herein, we report a rare case of L5 chance fracture and epidural hematoma in a 27-year-old female patient with AS. She was treated surgically but without bone fusion or decompressive laminectomy due to the neurologically intact status despite significant neural compression by the spinal epidural hematoma (SEH). We believe that conservative treatment with close observation of neurological status may be effective in SEH presenting with mild neurological symptoms despite significant neural compression.

Vertebral Artery Dissection Following Anterior Cervical Decompression and Artificial Disc Replacement.

Vertebral artery dissection (VAD) is a rare vascular cause of acute stroke. Although VAD may be classified as spontaneous or traumatic, it is increasingly recognized that trivial mechanical stress typically precipitates this potentially dangerous condition. Herein, we report a rare case of VAD and acute stroke following anterior cervical decompression and artificial disc replacement (ADR). To our knowledge, there have been no other cases of acute vertebrobasilar stroke caused by VAD following anterior cervical decompression and ADR. This case highlights that, although rare, acute vertebrobasilar stroke may occur after the anterior cervical approach.

A Rare Case of Aphasia Caused by Delayed Epidural Abscess 6 Years after Cranioplasty.

Cranioplasty following decompressive craniectomy for severe head trauma or stroke encompasses various cranial reconstruction techniques that use autograft or allograft materials. It not only provides protection and cosmetic benefits to the brain but also facilitates neurological function. One of the most important and undesirable complications of cranioplasty is graft infection, which usually develops within several days to months. Here, we report the case of a 46-year-old man who was admitted with aphasia caused by a delayed epidural abscess 6 years after cranioplasty. The possible pathophysiological mechanisms of this rare entity are discussed along with a review of the relevant literature.

Retroperitoneal Hematoma Caused by Lumbar Artery Injury during Percutaneous Disc Nucleoplasty: Successful Treatment Using Emergent Transarterial Embolization.

Although minimally invasive percutaneous disc nucleoplasty (PDN) has been widely used for discogenic back pain or soft-disc herniation of the lumbar spine, complications can occur. Although rare, iatrogenic vascular injuries during PDN are serious complications that can be fatal without rapid diagnosis and effective management. Here, we present the case of a 38-year-old male patient with an injury to the right fifth lumbar artery that occurred during PDN, which was successfully treated using emergent transarterial embolization. To the best of our knowledge, this is the first report of successful transarterial embolization without open hematoma evacuation for a lumbar artery injury that occurred during PDN.

Tension Pneumocephalus Caused by Ethmoidal Roof Fracture: Emergent Surgical Decompression.

Tension pneumocephalus is a neurosurgical emergency that occurs when air is trapped in the intracranial cavity, leading to brain compression and causing severe neurological symptoms such as decreases in motor function, sensory function, and consciousness. Most cases of pneumocephalus require conservative treatment; however, because of the possible fatal complications, rapid diagnosis and appropriate treatment are important. Here, we present the case of an 81-year-old male patient who had undergone head trauma three hours prior to being admitted to our emergency room (ER) because of mental cloudiness. The radiologic findings showed tension pneumocephalus caused by an ethmoidal roof fracture. Emergency reconstruction of the ethmoidal roof with craniotomy was performed to remove the intracranial air using normal saline irrigation. By sharing our experience with this case, we hope to provide an option for the treatment of such cases.

Lumbar Plexus Palsy Caused by Massive Psoas Hematoma Related to Vertebral Compression Fracture in a Patient with Liver Cirrhosis.

Osteoporotic vertebral compression fractures (VCFs) are common injuries in elderly patients and are usually stable because only the anterior column is involved. However, neurological deterioration may complicate osteoporotic VCFs, and most of them are related to canal invasion. Liver cirrhosis (LC) and its related complications have been identified as risk factors for an increased bleeding tendency, which, in turn, is associated with increased morbidity and mortality risks. We herein present a rare case of an osteoporotic VCF and a massive psoas hematoma that resulted in lumbar plexus palsy in a patient with LC after a stable-type spinal injury. To our knowledge, this is the first reported case of lumbar plexus palsy attributed to a liver-cirrhosis-related massive psoas hematoma and a stable VCF after minor trauma. This case highlights the potential risk of severe neurological deficits related to this type of common and seemingly trivial injury. The possible pathophysiological mechanisms are discussed and the relevant literature is reviewed.

The impact of awareness of terminal illness on quality of death and care decision making: a prospective nationwide survey of bereaved family members of advanced cancer patients.

OBJECTS: We aimed to assess whether awareness of a terminal illness can affect care decision making processes and the achievement of a good death in advanced cancer patients receiving palliative care services. METHODS: Awareness of terminal illness at the time of palliative care service admission was assessed by the health care professionals during the routine initial comprehensive assessment process and was recorded in the national terminal cancer patient registry. A follow-up nationwide bereavement survey was conducted, which contained questions regarding decision making processes and the Korean version of the Good Death Inventory. RESULTS: Among the 345 patients included in the final analysis, the majority (68.4%) of the patients were aware of the terminal illness. Awareness of the terminal illness tended to reduce discordances in care decision making (adjusted odds ratio = 0.55; 95% CI: 0.29-1.07), and increased the patients' own decision making when there were discordances between patients and their families (adjusted odds ratio = 3.79; 95% CI: 1.31-10.94). The Good Death Inventory score was significantly higher among patients who were aware of their terminal illnesses compared with those who were not (5.04 vs. 4.80; p = 0.013) and especially in the domains of 'control over the future' (5.18 vs. 4.04; p < 0.001), 'maintaining hope and pleasure' (4.55 vs. 3.92; p = 0.002), and 'unawareness of death' (4.41 vs. 4.26; p = 0.024). CONCLUSION: Awareness of the terminal illness had beneficial effect on the harmonious decision making, patient autonomy, and patient's quality of death. Disclosure of terminal illness should be encouraged.
