Introduction: Carotid sacrifice is a valuable tool in the treatment of select vascular lesions. Traditional coil embolization as the primary means of carotid sacrifice can be expensive, with high radiation exposure. We investigated the feasibility of a novel hybrid coil, the Penumbra occlusion device (POD), for carotid sacrifice in a swine model.
Methods: A total of eight common carotid artery sacrifices were performed in fully heparinized pigs under fluoroscopic guidance. A single POD device was deployed within each vessel, and intermittent follow-up angiography was performed to assess flow.
Results: Complete carotid occlusion was achieved in all cases with a single POD (time range 2-15 min) without any coil migration or intraprocedural complications. Once the anchor zone was stable, no distal migrations were observed during either proximal soft coil packing or during hand injected angiography. Complete occlusion was verified between 2 and 15 min following POD deployment.
Conclusions: Carotid artery sacrifice using a novel POD device is safe and effective, allowing for reduced radiation and material costs compared with any other described endovascular technique.

Clarifying the inceptive pathophysiology of hypertensive heart disease helps to impede the disease progression. Through coarctation of the infrarenal abdominal aorta (AA), we induced hypertension in minipigs and evaluated physiological reactions and morpho-functional changes of the heart. Moderate aortic coarctation was achieved with approximately 30 mmHg systolic pressure gradient in minipigs.

Background: Iatrogenic injury to neck vasculature is a potentially life-threatening complication of spine surgery. We present an illustrative case describing the use of the Pipeline Embolization Device (PED) in the emergent reconstruction of the vertebral artery (VA) following vessel laceration. In addition, we document a systematic review concerning the use of the PED in acute to chronic iatrogenic injury of the internal carotid or VAs.

Objective: As endovascular interventions become safer and their use more prevalent for treating extracranial pseudoaneurysms, fewer pseudoaneurysms are treated with medical therapy alone. This study aimed to assess the indications for intervention and the safety of medical management.
Methods: A dual-center retrospective analysis was conducted on patients diagnosed with extracranial carotid and vertebral pseudoaneurysms between December 2006 and June 2023.

Intracranial pseudoaneurysms account for approximately 1% of all intracranial aneurysms and are associated with high rebleeding risk and mortality. Traditional treatments of these lesions include microsurgical or endovascular reconstruction and parent vessel sacrifice. Reconstruction of the vessel is challenging due to poor vessel integrity and incomplete wall structure.

Background: The internal jugular vein (IJV) plays a major role in collecting venous blood from the cranium, face, and neck. Preserving or reconstructing at least one IJV during bilateral radical neck dissection (RND) allows preventing severe complications. The aim of this report was to present a variant of IJV reconstruction in bilateral radical neck dissection.
