PURPOSE: To report a rare variant of the posterior septal artery (PSA), which supplies blood to the posterior mucosa of the contralateral nasal septum.
CASE REPORT: A 31-year-old female patient underwent suture removal 14 days after septoplasty and developed left-sided epistaxis 6 h after suture removal. To safely and effectively relieve the patient from epistaxis, the cauterization of the left PSA was performed under general anesthesia. However, 24 h after the first surgical hemostasis, the patient experienced epistaxis again in the right nasal cavity. We have reviewed the patient's sinus computed tomography again and found a rare variant of PSA, which is the right-sided PSA passing through a bony canal in the left-sided nasal septum.
DISCUSSION: The variant of PSA well explained the failure of the first hemostatic surgery. Therefore, we again performed a cauterization of the right-sided PSA, after which the patient recovered and no further epistaxis occurred.
CONCLUSION: When cauterization of PSA is used to manage posterior epistaxis, it is necessary to pay attention to the possible variation in PSA.
