RESUMO
Introduction: It is common for the liver to be supplied blood by a hepatic artery branching off the coeliac trunk. Occasionally, a replaced common hepatic artery (RCHA), emerges from the superior mesenteric artery (SMA), can supply the liver in 1.5-4.0% of cases. Computed tomography (CT) angiography is a highly accurate method for identifying arterial anomalies, which may remain undetected until the time of surgery, leading to unexpected complications. Case presentation: A 53-year-old male exhibiting symptoms of decreased appetite, weight loss, vomiting, and altered sclera, urine, and stool colour, underwent a contrast-enhanced CT scan revealing biliary tract dilatation and pancreatic abnormalities, leading to a pancreaticoduodenectomy. During the surgery, an uncommon arterial finding-CHA from SMA-was noted. Pancreatic cancer was confirmed. The patient was discharged a week post-surgery without issues, emphasizing perioperative care progress. Discussion: The authors' study focused on the detection conditions of the same hepatic artery anomaly in eight cases reported between 2017 and 2023. In two of them the anomaly was discovered in cadaver by routine autopsy. In three cases, this variation was identified before the surgery, but in three other cases it wasn't detected until the surgical procedure. In the authors' case, due to multiple reasons, the anomaly remained undetectable until the surgery. Conclusion: This study underscores the importance of thorough preoperative evaluation to grasp vascular variations for better patient care. Also, a noteworthy observation in our case is that the surgeon identified an expanded hepatic vessel, prompting further investigation into this anomaly.
RESUMO
Acquired hemophilia A is a rare bleeding disorder. Rapid diagnosis with prolonged aPTT and low FVIII, and immediate use of bypassing agents and steroids are crucial for better outcomes, highlighting the importance of early recognition and management.
