Abstract
RATIONALE: Coagulation factor V deficiency is rare, and perioperative management of patients with this condition is particularly important, especially during major abdominal surgery. We present a case of a patient with pancreatic duct stones combined with coagulation factor V deficiency. We share our perioperative management experience. PATIENT CONCERNS: A 31-year-old man presented with recurrent upper abdominal pain for 2 years. DIAGNOSES: The diagnosis of pancreatic duct stones in the patient has been established through abdominal computed tomography and magnetic resonance imaging examinations. The diagnosis of factor V deficiency was initially identified through coagulation function tests, revealing significant prolongation of both aPTT and PT. Subsequent testing of coagulation factors and inhibitors demonstrated that the patient has a deficiency in coagulation factor V. Finally, genetic testing revealed that the factor V deficiency in this case is hereditary. INTERVENTIONS: The patient underwent a partial resection of the pancreatic head, and FFP was infused 1 hour before surgery. 600 mL of FFP was instilled 1 hour before the start of surgery along with 10 U of cryoprecipitate. and 600 ml of FFP were added during surgery. Postoperative treatment included intermittent FFP supplemental infusion in the first 5 days after surgery while monitoring the coagulation function. OUTCOMES: The patient underwent a successful surgery without any abnormal bleeding or oozing during the procedure. The postoperative recovery was smooth, with no abnormal bleeding. LESSONS: Patients with a deficiency of coagulation factor V are not contraindicated for surgery. Appropriate Fresh Frozen Plasma (FFP) replacement therapy can ensure the safe conduct of the surgical procedure. For patients with abnormal blood coagulation function, we recommend testing for coagulation factors and inhibitors, as well as performing genetic testing for abnormal coagulation factors, which can provide guidance on marriage and childbirth.
