Pancreatic arteriovenous malformation (PAVM) is predominantly caused by congenital factors and is an extremely rare vascular anomaly. The number of documented and reported cases in the literature remains very low.
We report a case of a 37-year-old male who was admitted to the hospital due to acute abdominal pain.
Computed tomography revealed an arteriovenous malformation in the tail of the pancreas and acute pancreatitis.
The patient underwent a distal pancreatectomy combined with splenectomy.
Histopathological examination confirmed the presence of an arteriovenous malformation in the tail of the pancreas along with acute pancreatitis. We believe that the acute pancreatitis was induced by the PAVM. The patient was discharged successfully and remained symptom-free during follow-up.
PAVM is a rare vascular abnormality occurring in the pancreas. Clinical manifestations can include gastrointestinal bleeding, intra-abdominal hemorrhage, pancreatitis, portal hypertension, and pancreatic pseudocyst. Diagnosis can be confirmed through ultrasound, contrast-enhanced computed tomography, magnetic resonance imaging, and digital subtraction angiography. Surgical treatment is an effective approach for symptomatic PAVM.
胰腺动静脉畸形（PAVM）主要由先天性因素引起，是一种极其罕见的血管异常。文献中记录和报道的病例数量仍然非常少。
我们报告一例37岁男性因急性腹痛入院。
计算机断层扫描显示胰腺尾部动静脉畸形和急性胰腺炎。
患者接受了胰体尾切除术联合脾切除术。
组织病理学检查证实胰腺尾部存在动静脉畸形并伴有急性胰腺炎。我们认为急性胰腺炎是由PAVM诱发的。患者成功出院，随访期间无症状。
PAVM是一种发生在胰腺的罕见血管异常。临床表现可包括胃肠道出血、腹腔内出血、胰腺炎、门静脉高压和胰腺假性囊肿。可通过超声、增强计算机断层扫描、磁共振成像和数字减影血管造影确诊。手术治疗是症状性PAVM的有效方法。
