“…Therefore, the definitive treatment is surgical resection of the affected lesion early to eliminate the cause of pain and prevent complications. Surgical resection should be considered before portal hypertension develops because portal hypertension is irreversible even after treatment [ 7 ]. Arterial embolization, irradiation, and transjugular intrahepatic portosystemic shunt are alternative options in patients at high surgical risk [ 8 ].…”

Arteriovenous malformation (AVM) of the gastrointestinal tract is a rare anomaly, mostly due to congenital reasons. Patients with pancreatic AVM can live without experiencing symptoms. It can present with gastrointestinal bleeding or portal hypertension, and diagnosis can be made by computed tomography (CT) or angiography. CT findings include multiple discrete intrapancreatic vessels. A 48-year-old man complained of abdominal pain with a sensation of fullness that radiated to the back for a month, associated with shortness of breath, loss of appetite, and unintentional weight loss of 33% in one month without nausea or vomiting. On physical examination, the abdomen was soft and lax with epigastric tenderness and a negative Murphy sign. Laboratory investigations showed high amylase with normal liver and kidney functions. CT showed pancreatic AVM. He underwent partial pancreatectomy and splenectomy. After the surgery, the patient reported an improvement in symptoms. All follow-up visits were uneventful. Pancreatic AVM is a rare disease, and the most significant chief complaint of most patients is gastrointestinal tract bleeding. It requires imaging depending on the signs and symptoms. The primary imaging modality is CT, with subtraction angiography for confirmation. Surgical treatment is the standard of management for most patients when tolerable. Additionally, early detection of these rare anomalies can avoid massive gastrointestinal tract bleeding and the development of resistance portal hypertension and can save patients’ lives if bleeding occurs.

“…TAE is less invasive for P-AVM management but carries a higher risk of recurrence and potential complications requiring additional treatments. Hakoda et al [ 20 ] (2022) reported that TAE may be associated with a higher risk of AVM recurrence and the potential for embolization of other portal branches because of the migration of embolic agents. Additionally, achieving complete embolization may be difficult as the AVM is often supplied by multiple feeding arteries.…”

“…They observed the progressive regression of P-AVM with no symptom recurrence despite incomplete embolization. Therefore, they suggested that TAE may be considered as a safe and effective treatment option for selected cases of symptomatic P-AVM, with surgical intervention reserved as a secondary option[ 20 ].…”

β cells are the main cells responsible for the hypoglycemic function of pancreatic islets, and the insulin secreted by these cells is the only hormone that lowers blood glucose levels in the human body. β cells are regulated by various factors, among which neurotransmitters make an important contribution. This paper discusses the effects of neurotransmitters secreted by various sympathetic and parasympathetic nerves on β cells and summarizes the mechanisms by which various neurotransmitters regulate insulin secretion. Many neurotransmitters do not have a single source and are not only released from nerve terminals but also synthesized by β cells themselves, allowing them to synergistically regulate insulin secretion. Almost all of these neurotransmitters depend on the presence of glucose to function, and their actions are mostly related to the Ca2+ and cAMP concentrations. Although neurotransmitters have been extensively studied, many of their mechanisms remain unclear and require further exploration by researchers.
