Abdominal hemorrhage after peritoneal dialysis catheter insertion: A rare cause of luteal rupture: A case report.

BACKGROUND: Abdominal hemorrhage is a complication of peritoneal dialysis catheter (PDC) insertion that cannot be neglected, and its causes are mainly related to surgical injury. This article reports a case of massive abdominal hemorrhage that was caused by a rare rupture of corpus luteum shortly after PDC during the initiation of peritoneal dialysis (PD) insertion. CASE SUMMARY: A 37-year-old woman was surgically placed a Tenckhoff catheter because of end-stage renal disease. On the third postoperative day, the color of the abdominal drainage fluid was pink, and deepened gradually. It turned pale after initiating conservative treatment. On the tenth postoperative day, the color of the abdominal drainage fluid suddenly turned dark red, and the color progressively deepened. The patient's hemoglobin dropped from 88 g/L to 57 g/L. Abdominal computed tomography (CT) indicated abdominal effusion and a high-density shadow in the abdominal cavity. The surgeon performed a laparotomy and found that the corpus luteum had ruptured on the right side and a left ovarian blood body had formed. The gynecologist repaired the ovary and performed a bilateral oophoroplasty. After the operation, the patient stopped bleeding and hemodialysis was temporarily stopped. PD was resumed after half a month. The patient's condition improved, and she was discharged 14 d after the laparotomy. CONCLUSION: If abdominal hemorrhage occurs in women of childbearing age after PDC insertion, luteal rupture should be considered as the cause.

[Analysis of CYP17A1 gene mutation in a child patient with 17 alpha-hydroxylase/17, 20-lyase deficiency].

OBJECTIVE: To analyze CYP17A1 gene mutations in a child patient with 17 alpha-hydroxylase/17, 20-lyase deficiency (17OHD), and to review characteristics of CYP17A1 gene mutations in Chinese patients with 17OHD. METHODS: Clinical data were collected. PCR and DNA sequencing were performed to detect mutations in the patient. RESULTS: The patient has presented classical features of 17OHD including hypertension, hypokalemia, decreased sex hormones and plasma cortisol, and elevated blood adrenocorticotrophic hormone. A compound heterozygous mutation c.987C>A and c.985del was detected in the CYP17A1 gene, which resulted in two premature stop codons at positions 328 and 417. CONCLUSION: A compound mutation, c.987C>A and c.985del, has been identified in a patient with 17OHD. Among CYP17A1 gene mutations identified in Chinese patients, missence mutations have been most common, and exons 5 and 8 have been the mutation hotspots.
