With the Food and Drug Administration approval of stent retriever technology in 2012, there is a significant improvement in recanalization
rates compared with older devices with regard to LVOs (Fargen et al.
Here we are in year 2015, and controversy continues regarding the best protocols to treat acute stroke with clot-dissolving drugs like tPA and/or mechanical recanalization
techniques like cerebral artery stenting.
To improve the efficiency of ultrasound vascular recanalization
, we have developed a waveguide tube type without working head to the distal end of a cylindrical slotted spring.
12 guide to coronary angioplasty for recanalization

Some practitioners have advocated primary angioplasty and stenting, similar to the coronary standard of care, as a more rapid way of achieving recanalization
while treating an underlying, causative, lesion.
2 percent (160 of 202) of patients with missing angiographic data, as determined by an independent laboratory, achieved the highest degree of recanalization
9 mg/kg (maximum dose 90 mg) over 60 minutes with 10% of the dose given as a bolus over 1 minute (7) with the caveat that IV tPA has been associated with lower recanalization
However, 10 to 20% of patients undergoing hemostatic embolization rebleed within 72 hours, probably due to recanalization
or re-filling through the extensive collaterals (10).
Cranial MRI showed new significant ring-enhancing lesions in the right temporal lobe (Figure 1B) and MR venography demonstrated recanalization
in the right transverse sinus (Figure 1D).
For example, a patient with an occluded middle cerebral artery who undergoes successful thrombolytic treatment with rapid vessel recanalization
will not show any detectable GFAP release as long as the resulting infarction is very small or nonexistent (31).
5) Likely complications include ischemia and ischemic pain after embolization, and recanalization
MIAMI BEACH -- Deployed stents produced unexpectedly good outcomes in a series of 19 stroke patients with large-vessel occlusions that resisted recanalization
by more conventional treatments.
