ABSTRACT
Liposuction is a surgical procedure performed worldwide. Although many fatal complications of liposuction have been reported, to our knowledge, no cases of fatal liposuction complications specifically related to the face region have been reported. Here, we present a case of a woman in her 30s who developed a cervical hematoma and upper airway obstruction following facial liposuction. We present this unique case to highlight the rare occurrence of fatal complications specific to facial liposuction. The patient underwent liposuction during surgery at a cosmetic surgical clinic and awoke from anesthesia after the procedure. Two hours later, she developed a neck swelling and dyspnea. While the anesthesiologist managed her airway, she went into cardiopulmonary arrest. She was then transferred to the emergency room but died on day 7 of hospitalization. The autopsy revealed swelling of the right cheek and mandible, a subcutaneous hematoma in the same area, and laryngeal edema. A damaged facial artery branch was identified, which was consistent with the computed tomography (CT) findings on admission. CT also showed that the hematoma compressed the right internal jugular vein, suggesting that venous outflow impairment caused by the hematoma may have exacerbated the airway obstruction. This case reveals that cervical hematoma caused by facial liposuction can cause fatal upper airway obstruction and the onset of the hematoma may be gradual.
ABSTRACT
Falls from height pose a significant public health concern in urban regions, including the highly urbanized Greater Tokyo Area. The Japanese population is characterized by high rates of suicide and psychoactive drug usage, underscoring the importance of investigating these attributes in falls from height. This study aimed to retrospectively analyze the alcohol and toxicological aspects influencing falls from height in the Greater Tokyo Area between 2014 and 2022 and compare the findings with existing reports on other populations. In total, 75 cases of falls from height and 159 cases of natural deaths were included. Consistent with previous findings, Fisher's exact test revealed a predominance of males (66.67%, 50/75) and young adults (57.33%, 43/75) in falls from height. Multivariate logistic regression analysis identified antidepressant usage as the most significant risk factor within the target population, while younger individuals under alcohol influence constituted another high-risk group. Notably, contradictory to other populations, female individuals involved in fatal falls in the Greater Tokyo Area exhibited a higher frequency of alcohol consumption than males (48.00%, 12/25 vs. 26.00%, 13/50), and most of them were associated with suicide (83.33%, 10/12). These findings elucidate the population characteristics that pose a high risk for fatal falls from height in Japan and can serve as a reference for other Asian populations residing in similar megacities.

Intracranial vertebral artery dissection (IVAD) is rare and potentially fatal due to the risk of secondary subarachnoid hemorrhage once ruptured. Unruptured traumatic IVAD is even rarer and can result in ischemic stroke, yet mostly benign when timely diagnosed. Herein, we present an uncommon case of a patient who underwent a fatal ischemic stroke induced by unruptured traumatic IVAD. The patient was symptomatic soon after being physically assaulted but left untreated until acute deterioration for multiple brain infarctions occurred, secondary to IVAD-induced cerebellar stroke. Fifteen days later, he died, regardless of an urgently performed thrombectomy. Multiple serial histologic examinations revealed an unruptured dissection of the intracranial vertebral artery with a slit-like tear of the intimal and medial layers, considered to be the culprit lesion. The 15-day prolonged onset of stroke was rare in traumatic IVADs. Furthermore, the slit-like tear of the intimal layer in our case may support the initial intimal laceration hypothesis for VAD pathogenesis. Since limited pathohistological information is available regarding ischemic IVAD, we believe this rare case will be beneficial in understanding the pathophysiology of ischemic IVAD.
