Gastric Artery Embolization

BACKGROUND: Although transcatheter arterial embolization for pseudoaneurysms is already well-established, ureteral artery pseudoaneurysm embolization is extremely rare. The present case shows a successful transcatheter arterial embolization for pseudoaneurysms in the ureteral branch of the renal artery due to ureteral invasion from gastric cancer. CASE PRESENTATION: A 57-year-old female presented with gross hematuria after treatments for poorly differentiated gastric adenocarcinoma...

Objective: To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy.

Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University...

BACKGROUND: We describe a case of segmental arterial mediolysis in which a vessel ruptured on two consecutive days. CASE PRESENTATION: A 69-year-old man presented with sudden-onset abdominal pain. Computed tomography showed a hematoma in the gastric wall. The patient was discharged after the pain was relieved but returned 8 h later with abdominal pain and shock. Repeated computed tomography revealed a massive intra-abdominal hemorrhage without previous aneurysm formation...

BACKGROUND: Studies have shown minimally invasive esophagectomy (MIE) to be a feasible surgical technique in treating esophageal carcinoma. Postoperative complications have been extensively reviewed, but literature focusing on intraoperative complications is limited. The main objective of this study was to report major intraoperative complications and 90-day mortality during MIE for cancer. METHODS: Data were collected retrospectively from 10 European esophageal surgery centers...

Overweight and obesity are one of public health's major problems in the world. Conservative treatment with exercise, diet and pharmacotherapy is often ineffective, especially in the long term. Bariatric surgery is the gold standard method for a sustained long-term weight loss. Recently the endovascular technique of bariatric artery embolization (BAE) has been studied as an obesity and overweight treatment, with promising results. The goal of this article is to analyze the rationale behind BAE and to provide an up-to-date analysis of its strengths and limitation in comparison with bariatric surgery as a treatment for obesity...

Pseudoaneurysms are a commonly encountered pathology, though pseudoaneurysms of the visceral arteries are a less frequent, but potentially deadly entity. Transarterial embolization is the typical treatment of visceral pseudoaneurysms, but success is dependent on anatomy that is conducive to selecting the supplying vessel. Abdominal ultrasound is a viable method to effectively treat visceral pseudoaneurysms when transarterial embolization is not possible. It is also an excellent example of the growing utilization of ultrasound guidance in various interventional radiologic procedures...

INTRODUCTION: Upper gastrointestinal (GI) bleeding in patients with roux-en-Y gastric bypass can be difficult to localize. Marginal ulcers are the most common cause, but a broad differential should be maintained in cases of severe bleeding, especially since the stomach and duodenum are not easily accessible by regular upper endoscopy. PRESENTATION OF CASE: A 38-year-old female with Roux-en-Y gastric bypass presented with abdominal pain and hematochezia. Due to history of smoking and heavy use of ibuprofen, she was initially thought to have a bleeding marginal ulceration...

OBJECTIVES: To identify the appropriately sized imaging-visible embolics with balanced safety and efficacy for bariatric arterial embolization (BAE) in a preclinical model. MATERIALS AND METHODS: Twenty-seven pigs were divided into three cohorts. In cohort I, 16 pigs were randomized to receive either (n=4 each) 40-100 μm in one or two fundal arteries, or 70-340 μm radiopaque microspheres in two fundal arteries, or saline. In cohort II, three pigs underwent renal arterial embolization with either custom made 100-200 μm, 200-250 μm, 200-300 μm, 300-400 μm radiopaque microspheres, or Bead Block 300-500 μm with microsphere distribution assessed histologically...

As a promising drug delivery system, the temperature-sensitive liquid embolic agent (TempSLE) has yet to be reported in animal experiments in treating gastric cancer. We observed and compared computed tomography (CT) imaging changes, tumor volume, HE staining, and immunohistochemistry after transcatheter arterial chemoembolization (TACE) treatment in rabbit VX2 gastric cancer models to clarify the effectiveness of TempSLE loaded with oxaliplatin (TempSLE/Oxa) in treating gastric cancer. One milliliter TempSLE can be loaded with 20 mg oxaliplatin...

BACKGROUND: Severe burns can readily induce gastric and duodenal mucosal erosions and superficial ulcers. In severe cases, haemorrhage or perforation of peptic ulcers might occur, threatening the lives of patients. At present, gastrointestinal haemorrhage after burns is treated mainly with drugs and gastrointestinal endoscopy. However, multidisciplinary treatment of gastroscopy combined with vascular embolization is rare. CASE: A boy aged 3 years and 4 months was admitted to the hospital, scalded by boiling water on multiple parts of the body...

RATIONALE: In 1865, Trousseau first discovered pulmonary embolism caused by multiple venous thrombosis in patients with gastric cancer, and later all clinical manifestations of malignant patients during pathogenesis due to abnormal coagulation and fibrinolysis were referred to collectively as Trousseau syndrome. Trousseau syndrome is not a benign thrombophlebitis, and when diagnosed it requires immediate treatment. The survival rate over 1 year is only 12%. Stroke in cancer patients has distinct characteristics different from conventional stroke and has higher mortality...

BACKGROUND: The combination of atezolizumab (ATZ) and bevacizumab (BVZ) was approved as first-line systemic therapy for advanced hepatocellular carcinoma (HCC) owing to its superior rates of response and patient survival. However, ATZ + BVZ is associated with increased risk of upper gastrointestinal (GI) bleeding, including arterial bleeding, which is rare and potentially fatal. We present a case of massive upper GI bleeding from a gastric pseudoaneurysm in a patient with advanced HCC who had been treated with ATZ + BVZ...

We present the case of a 78-year-old woman who had unresectable advanced gastric cancer that had invaded the pancreas. Her hemoglobin level dropped to 7.0 g/dL during third-line chemotherapy. An upper gastrointestinal endoscopy showed a clot in the stomach, but the bleeding point could not be identified. She received a blood transfusion, but on the third day, she experienced a hemorrhagic shock. We conducted transcatheter arterial embolization(TAE)and subsequently performed embolization of the right gastroepiploic artery and the descending branch of the left gastric artery with an absorbable gelatin sponge...

BACKGROUND: In orthotopic liver transplantation (OLT), preserving an aberrant hepatic artery (AHA) can increase the number of arterial anastomoses and may lead to arterial-related complications. AHA includes accessory hepatic artery and replaced hepatic artery. Herein, the purpose of our research is to evaluate the requirement for accessory anastomosis in OLT. METHODS: We retrospectively reviewed a total of 95 patients who underwent OLT in our hospital between April 2020 and December 2022...

METHODS: This Clinical Practice Update was commissioned and approved by the AGA Institute Clinical Practice Updates Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership, and underwent internal peer review by the Clinical Practice Updates Committee and external peer review through standard procedures of Clinical Gastroenterology and Hepatology...

The formation of left gastric artery aneurysms (LGAAs) is a very rare complication of microscopic polyangiitis (MPA). Hemorrhage due to ruptured LGAAs is life threatening. In this case report, an 81-year-old female patient diagnosed with MPA developed massive bleeding from a ruptured LGAA and hemorrhagic shock during hospitalization. The patient underwent endovascular therapy to successfully embolize the aneurysm with microcoils and recovered postoperatively.

Dieulafoy lesion is an aberrant submucosal vessel that can erode into the overlying tissue leading to hemorrhage. It is a rare but important cause of gastrointestinal bleeding. We present a case of a patient who developed an acquired Dieulafoy lesion 39 years after splenectomy. Abdominal computed tomography showed an aberrant vessel from a branch of the left phrenic artery, coursing through the gastric fundus to supply a splenule. Angiography with embolization of the aberrant vessel resulted in no further bleeding...

Upper gastrointestinal hemorrhage is an uncommon but can be a lethal presentation of a pseudoaneurysm because a rupture is associated with a 40%-80% mortality rate. We report a rare case of left gastric artery pseudoaneurysm secondary to peptic ulcer disease presenting as an upper gastrointestinal hemorrhage.

We describe the successful n -butyl cyanoacrylate (NBCA) packing of a large gastroduodenal artery pseudoaneurysm after distal pancreatectomy in a patient with a history of subtotal esophagectomy and gastric tube reconstruction. The pseudoaneurysm was considered to be caused by direct injury to the gastroduodenal artery (GDA). However, embolization of the GDA was not possible in this case because due to prior esophageal surgery, the main blood vessel supplying the gastric tube was the right epigastric artery from the GDA...
