Over the past two decades, transcatheter arterial embolization has become the first-line therapy for the management of upper gastrointestinal bleeding that is refractory to endoscopic hemostasis. Advances in catheter-based techniques and newer embolic agents, as well as recognition of the effectiveness of minimally invasive treatment options, have expanded the role of interventional radiology in the management of hemorrhage for a variety of indications, such as peptic ulcer bleeding, malignant disease, hemorrhagic Dieulafoy lesions and iatrogenic or trauma bleeding. Transcatheter interventions include the following: selective embolization of the feeding artery, sandwich coil occlusion of the gastroduodenal artery, blind or empiric embolization of the supposed bleeding vessel based on endoscopic findings and coil pseudoaneurysm or aneurysm embolization by three-dimensional sac packing with preservation of the parent artery. Transcatheter embolization is a fast, safe and effective, minimally invasive alternative to surgery when endoscopic treatment fails to control bleeding from the upper gastrointestinal tract. This article reviews the various transcatheter endovascular techniques and devices that are used in a variety of clinical scenarios for the management of hemorrhagic gastrointestinal emergencies.
Diaphragmatic hernia in the absence of trauma in adults is very rare. It occurs as a result of unilateral diaphragmatic agenesis. The diagnosis of this rare condition is typically made in early infancy. However, in asymptomatic patients, the diagnosis is often delayed for months and even years. We present a case of a 27-year-old female, who was referred 48-hours after Caesarean section with suspected pulmonary embolism. Computed tomography scan revealed herniation of the liver as well as bowel loops into the right hemi-thorax. Exploration through a right thoracotomy revealed right diaphragmatic agenesis. The contents were reduced into the abdomen, and the defect was repaired using a mesh. The patient had an uneventful postoperative recovery and was discharged home 10 days later. This case highlights the acute late presentation of right diaphragmatic eventration with abdominal visceral herniation in adulthood. The condition may be triggered by the increasing size of gravid uterus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
