False Memories

False memories represent a cognitive distortion in which individuals recall events that did not happen, or remember them in an altered form. This phenomenon highlights the brain's constructive nature in processing and recalling memories, emphasizing that memory is not a perfect representation of past events but rather a dynamic reconstruction influenced by various factors. One primary source of false memories is misattribution, where individuals incorrectly associate external information with...

Histological and biochemical modifications after aneurysm endograft exclusion are still unclear. We describe a new model of endograft implantation on a murine aneurysm. Through thrombus analysis with and without persistant circulating blood stream interface, and new endovascular biomaterials evaluation, this model will help to better understand endovascular aneurysm exclusion pathobiology.

FAQs
A false aneurysm commonly has a connecting neck between the artery and the contained blood collection. Blood moving through this channel can produce turbulent flow within the sac, a feature that Doppler ultrasonography can help identify. Demonstrating both the sac and its communicating flow helps distinguish the lesion’s vascular behavior and supports accurate clinical assessment.
The communicating neck provides the pathway through which arterial blood enters the contained collection. Its presence explains why the lesion can remain connected to the circulation and why blood flow may persist within the sac. Evaluating this connection also clarifies the lesion’s relationship to the parent artery and helps guide treatment planning.
Clinical recognition matters because a false aneurysm can enlarge, rupture, or cause bleeding. It may also contribute to distal ischemic complications, in which downstream tissues receive inadequate blood flow. Identifying the sac, its flow, and nearby anatomical relationships allows clinicians to consider treatment before these vascular consequences become more serious.
Doppler ultrasonography can identify the sac and demonstrate blood flow associated with the lesion. Computed tomography angiography provides imaging of the sac and its relationship to nearby structures. Together, these modalities support recognition of the vascular complication and provide anatomical information relevant to selecting an appropriate management approach.
Management options include ultrasound-guided compression, thrombin injection, endovascular repair, and surgery. These approaches provide different ways to address the communicating vascular lesion, either through image-guided treatment or repair of the affected vessel. The clinical evaluation of flow and anatomy helps guide which option is considered for an individual case.
Imaging is especially useful when clinicians need to confirm the lesion, characterize blood flow, or determine how the sac relates to nearby structures. These findings connect diagnosis with treatment planning, including consideration of compression, thrombin injection, endovascular repair, or surgery. This process is intended to reduce risks such as expansion, rupture, bleeding, and distal ischemia.
