Celiac trunk angiography with balloon occlusion of splenic artery for diagnosis and treatment of splenic steal syndrome.

Splenic steal syndrome (SSS) post liver transplant is a potential cause of graft dysfunction in the setting of peripheral hepatic arterial bed resistance and redirection of blood flow to a dominant splenic artery resulting in reduction of hepatic arterial inflow. We report utilization of balloon occlusion of the proximal splenic artery as an objective measure to confirm the diagnosis of SSS in a patient with orthotopic liver transplant followed by successful treatment with proximal splenic artery embolization using Gelfoam and Amplatzer vascular plug. Written informed consent for the publication of this case report was obtained from the patient.

Transcatheter embolization is an important tool in the treatment of pulmonary artery and bronchial artery pseudoaneurysms, malformations, and hemorrhage. Migration of coils, particularly through erosion into the associated bronchus, is a rare but known potential complication after the use of intravascular embolization coils in the pulmonary vasculature. Here we present a case of migration of segmental pulmonary artery coils through the right lower lobe bronchus and proximally through the vocal cords, causing significant symptoms of discomfort, hemoptysis, and ongoing expectoration of coils necessitating thoracoscopic right lower lobectomy.

Background: Variability in long-term endovascular treatment outcomes for intracranial aneurysms has prompted questions regarding the effects of these treatments on aneurysm hemodynamics. Endovascular techniques disrupt aneurysmal blood flow and shear, but their influence on intra-aneurysmal pressure remains unclear. A better understanding of aneurysm pressure effects may aid in predicting outcomes and guiding treatment decisions.

Background: Hepatic artery infusion pump (HAIP) chemotherapy is a locoregional treatment for intrahepatic malignancies. HAIPs are surgically implanted, and the catheter tip is typically inserted into a ligated gastroduodenal artery stump. Potential complications at the catheter insertion site include dehiscence, pseudoaneurysm or extravasation, and adjacent hepatic arterial stenosis and thrombosis.

Tandem occlusion due to acute cervical carotid artery dissection should be promptly treated with thrombectomy for reperfusion. If the cervical lesion has reached severe stenosis or complete occlusion, balloon angioplasty and, in certain cases, carotid artery stenting should be performed before thrombectomy for the intracranial lesion. Angioplasty or stent placement is performed in the true lumen, but securing the placement is challenging when the true lumen cannot be determined.
