Hypotension and Bradycardia After Brachiocephalic Artery Stenting: A Case Report.
Cureus
December 2024
Department of Neurosurgery, Hakodate Neurosurgical Hospital, Hokkaido, JPN.
Angioplasty and stenting of brachiocephalic artery stenosis can be complicated by ischemic stroke, local hematoma, thromboses, or dissection of access vessels. However, hemodynamic instability has not been reported as a complication of this treatment. We report the case of an 83-year-old man who developed hypotension and bradycardia after brachiocephalic artery stenting.

Department of Radiology, The First Affiliated Hospital of Chongqing Medical University, Chongqing, China.
Objective: To establish and validate a model based on hyperdense middle cerebral artery sign (HMCAS) radiomics features for predicting hemorrhagic transformation (HT) in patients with acute ischemic stroke (AIS) after endovascular treatment (EVT).
Methods: Patients with AIS who presented with HMCAS on non-contrast computed tomography (NCCT) at admission and underwent EVT at three comprehensive hospitals between June 2020 and January 2024 were recruited for this retrospective study. A radiomics model was constructed using the HMCAS radiomics features most strongly associated with HT.
Whey Protein-Based Hydrogel Microspheres for Endovascular Embolization.
ACS Appl Bio Mater
January 2025
Department of Radiology, University of Minnesota, Minneapolis, Minnesota 55455, United States.
Transarterial embolization (TAE) is an image-guided, minimally invasive procedure for treating various clinical conditions by delivering embolic agents to occlude diseased arteries. Conventional embolic agents focus on vessel occlusion but can cause unintended long-term inflammation and ischemia in healthy tissues. Next-generation embolic agents must exhibit biocompatibility, biodegradability, and effective drug delivery, yet some degradable microspheres degrade too quickly, leading to the potential migration of fragments into distal blood vessels causing off-target embolization.

Department of Cardiothoracic Surgery, Jefferson Health Abington Hospital, Abington, PA, USA.
Article Synopsis
- Utilization of cangrelor as a bridging therapy to cardiac surgery has been noted for stent placement, but less so for endovascular revascularization.
- The case involves a 47-year-old female with a significant arterial dissection requiring a Viabahn endoprosthesis and subsequent cardiac procedures.
- A combination of cangrelor, aspirin, and bivalirudin was employed to manage the patient’s coronary disease and ensure the effectiveness of the surgical intervention, showcasing a multi-disciplinary approach in complex cases.
Acute Necrotizing Pancreatitis Leading to Hemosuccus Pancreaticus and Hemorrhagic Shock in the Setting of Decompensated Cirrhosis.
Cureus
December 2024
Department of Gastroenterology, Scripps Mercy Hospital, San Diego, USA.
Hemosuccus pancreaticus (HP) is a rare, life-threatening cause of upper gastrointestinal bleeding, often linked to chronic pancreatitis and pseudoaneurysm rupture into the pancreatic duct. However, its occurrence in acute necrotizing pancreatitis with decompensated cirrhosis is exceedingly rare and poses significant diagnostic and treatment challenges. We report a case of a 34-year-old male with decompensated alcoholic cirrhosis who developed hemorrhagic shock from HP following acute necrotizing pancreatitis.
