Source: Schregel, K., et al. Optimized Management of Endovascular Treatment for Acute Ischemic Stroke. J. Vis. Exp. (2018).This video demonstrates the endovascular treatment of acute ischemic stroke using the stent retriever-assisted vacuum-locked extraction technique. A guiding sheath is introduced through the femoral artery to reach the clot. A catheter with a stent retriever secures and extracts the clot. Vascular imaging is done to confirm successful reperfusion.

Base Excision Repair

2020
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template. The first step of...

Source: Robert M. Rioux, Ajay Sathe & Zhifeng Chen, Pennsylvania State University, University Park, PA Vacuum is required for a number of laboratory procedures. This is most routinely achieved in the laboratory by the use of vacuum pumps. In addition to working at low pressures, vacuum pumps can also be used to enable rapid changing of the atmospheres in a reactor or flask by evacuation and backfilling.

FAQs
The vacuum creates negative pressure that draws targeted tissue into the probe’s cutting aperture. Once tissue enters this opening, the cutting mechanism separates it, and repeated sampling cycles progressively remove the lesion. This coordinated suction-and-cutting action allows the operator to collect multiple tissue portions through the same access point rather than enlarging the incision for each sample.
Imaging guidance is central because it directs the probe to the lesion and supports controlled tissue removal. Ultrasound or mammography can show the target while the probe is positioned, helping repeated sampling remain focused on the selected area. The guidance therefore links the mechanical action of the device with the anatomical location that requires assessment or removal.
Compared with open surgical excision, this approach is designed for selected lesions that can be managed through a small skin incision. The potential practical advantages described for appropriate benign breast lesions include less scarring and a shorter recovery time. It is therefore an alternative in suitable cases, not a universal replacement for conventional surgery.
Although tissue is removed therapeutically in some cases, the excised material also provides an opportunity for histopathological examination. Studying the removed tissue can support diagnosis and inform treatment planning, rather than relying only on imaging appearance. This makes the procedure relevant when clinicians need both lesion removal and assessment of the tissue that was excised.
During an image-guided workflow, imaging identifies the lesion, the hollow probe is positioned within it, and vacuum suction draws tissue toward the cutting aperture. Repeated sampling then removes the selected target through the existing small incision. The sequence combines localization, probe placement, tissue capture, cutting, and continued removal rather than a single extraction.
In medicine, Vacuum-assisted Excision is especially relevant to selected benign breast lesions when complete removal is appropriate and the lesion can be managed with the technique. The removed tissue can then undergo histopathological examination, providing information that supports diagnostic interpretation and treatment planning. Its value therefore spans minimally invasive treatment and confirmation of tissue characteristics.
