Vascular Complications in Pediatric Pancreatitis: A Case Series

The Importance of Early Detection and Minimally Invasive Treatment of Pseudoaneurysms Due to Chronic Pancreatitis: Case Report

The occurrence of the pseudoaneurysm of visceral arteries in the field of chronic pancreatitis is a very rare complication that represents a life-threatening condition. The higher frequency of this complication is in the necrotic form of pancreatic inflammation, especially in patients with formed peripancreatic necrotic collections. The degradation of the arterial wall leads to bleeding and transforms these necrotic collections into a pseudoaneurysm. Urgent endovascular angioembolization is the first choice in the therapeutic approach as a valid minimally invasive solution with very satisfactory immediate and long-term outcomes. This successfully avoids open surgery, which is associated with a high mortality rate in these patients, especially in acute-on-chronic pancreatitis.

Left Gastric Artery Pseudoaneurysm Complicating Chronic Calcifying Pancreatitis in a Child

A left gastric artery pseudoaneurysm is a rare complication of pancreatitis and is associated with significant morbidity and mortality. We report a 14-year-old male with severe abdominal pain and a palpable upper abdominal mass, earlier diagnosed as chronic idiopathic calcifying pancreatitis, and awaiting surgical intervention. Computed tomography showed a pseudocyst and a pseudoaneurysm in the lesser sac near the left gastric artery. The patient underwent successful angiographic coiling of the left gastric artery and definitive pancreatic surgery weeks thereafter. The early detection and interventional radiologic management of the vascular complication averted a life-threatening hemorrhage without emergency surgery in a pediatric patient.

Adolescent Acute Pancreatitis Complicated With Pseudoaneurysms and Venous Thrombosis

Vascular complications, such as pseudoaneurysms and thrombosis, are uncommon in pediatric acute pancreatitis (AP); hence, treatment experience remains limited. Here, we report a case of adolescent AP complicated with pseudoaneurysms and venous thrombosis simultaneously. Even after multiple endovascular embolizations for pseudoaneurysms, the patient experienced hemorrhagic shock resulting from pseudoaneurysm rupture after taking anticoagulants for thrombus. Inevitably, a total pancreatectomy was performed to prevent bleeding and control local complications. In AP, even among the pediatric population, a therapeutic dilemma between bleeding prevention and anticoagulation for thrombosis may occur. Despite the lack of experience with AP and its complications, a total pancreatectomy may become an alternative therapy for refractory AP or its complications.

Successful Treatment of Splenic Vein Thrombosis Secondary to Acute Pancreatitis with Oral Anticoagulants: A Pediatric Case Series

BACKGROUND Two Pediatric Patients with Splanchnic Venous Thrombosis as a Complication of Acute Pancreatitis Successfully Treated with Low-Molecular-Weight Heparin and Rivaroxaban CASE REPORT Case 1: A 13-year-old girl presented with a second attack of acute pancreatitis. She developed a non-occlusive splenic vein thrombosis diagnosed by CT scan on the sixth day of hospitalization. Injectable low-molecular-weight heparin was started during hospitalization and switched to oral rivaroxaban at discharge. Imaging at follow-up showed resolution of thrombosis. Case 2: A 9-year-old girl with history of acute recurrent pancreatitis presented with a third attack of acute pancreatitis. An occlusive splenic vein thrombosis with extension into the portal vein and superior mesenteric vein and necrotizing pancreatitis was seen on CT scan on the third day of hospitalization. Low-molecular-weight heparin was initiated during hospitalization and was switched to oral rivaroxaban at discharge. Imaging at follow-up demonstrated nearly complete resolution of the extensive thrombosis. CONCLUSIONS Splanchnic venous thrombosis remains a rare complication of pediatric pancreatitis. Anticoagulant use in patients with these complications remains controversial. Direct oral anticoagulants are as safe and effective as low-molecular-weight heparin and should be considered for use in children instead of low-molecular-weight heparin due to its advantages, including the availability of enteral forms of administration.

Case Report: Splanchnic Vein Thrombosis as a Complication of Necrotizing Acute Pancreatitis in a Pediatric Patient

Splanchnic vein thrombosis is an unusual manifestation of venous thromboembolism and includes portal vein thrombosis, mesenteric veins thrombosis, splenic vein thrombosis, and the Budd-Chiari syndrome. The most common risk factors include hematologic and autoimmune disorders, hormonal therapy, liver cirrhosis, solid abdominal cancer, recent abdominal surgery, and abdominal infections or inflammatory conditions, such as pancreatitis. Splanchnic vein thrombosis in acute pancreatitis is most commonly associated with the severe form of the disease and pancreatic necrosis. This report describes a case of splanchnic vein thrombosis as a complication of necrotizing acute pancreatitis in a pediatric patient. Splanchnic vein thrombosis was incidentally detected on contrast-enhanced computed tomography to assess the pancreas. There was no evidence of prior risk factors for the thrombotic condition. The patient was treated with anticoagulation and showed complete resolution after recovery from necrotizing acute pancreatitis, at a 16-month follow-up. The complication of necrotizing acute pancreatitis with splanchnic vein thrombosis in pediatric age is a rare presentation.

Multidisciplinary Approach to the Care of Children With Acute Recurrent Pancreatitis and Chronic Pancreatitis

OBJECTIVES

The aim of this article is to provide guidance to centers and organizations on the personnel (both physician and nonphysician) needed to create and sustain an optimal team, along with potential alternatives, to provide care to children with acute recurrent pancreatitis and chronic pancreatitis.

METHODS

This document was developed in collaboration with the North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) Pancreas Committee and the National Pancreas Foundation (NPF) after several meetings.

RESULTS

This document highlights both physician and nonphysician personnel needed to provide multidisciplinary care to children with pancreatitis per the recommendation of the NASPGHAN Pancreas Committee members in year 2021 and added to the currently published NPF criteria. We summarize how the NPF criteria would fit with the recently published pediatric pancreatitis society articles from the NASPGHAN.

CONCLUSIONS

It is important to manage children with acute recurrent pancreatitis and chronic pancreatitis in a multidisciplinary setting. There is need to study the impact of these personnel on the outcomes of children with pancreatitis.
