On autopsy, the incidence increases up to 90 per 100,000 population.1 The condition is often misread by transabdominal ultrasonography as cholecystitis leading to unnecessary surgery as was the case with our patient.5 The pathogenesis is a relation to embryological abnormality happening in the 4th week of an embryological period of failure of a ventrocaudal bud to develop from the hepatic diverticulum, or failure of the gallbladder and cystic duct to
recanalize.6 Authors have classified the cases into three groups.
(18) The CADISS trail investigators also found that 33% of grade 4 injuries
recanalize and do so without sequelae.
Therefore, CTO PCI can be unpredictable, with some seemingly simple lesions turning out to be highly challenging to
recanalize. Thus by helping plan the time and resources required for procedures would improve outcomes9.
We were able to
recanalize the blood vessel in under 9 minutes with the entire procedure lasting less than 17 minutes.
The umbilical vein however has been speculated to spontaneously
recanalize during portal hypertension to serve as a hepatofugal, decompressing collateral [12].
After two failed antegrade attempts in the past, the retrograde CTO technique was applied to
recanalize the RCA.
It has been studied in combination with aspirin, low molecular weight heparin (tinzaparin), and intravenous (i.v.) r-tPA therapy in several dosing regimens, since r-tPA alone is inadequate to
recanalize large arterial occlusions in approximately 50% of cases.
* Recanalization--Type II anatomic failure refers to veins that were initially confirmed to be occluded, but later
recanalize, either partially or completely.
High-frequency mechanical vibration to
recanalize chronic total occlusions after failure to cross with conventional guidewires, J Invasive Cardiol 18: 85-91.
Although transhepatic portal vein angioplasty is of great use to
recanalize the true lumen of the occluded portal vein, the application of this route should be cautiously considered in patients with portal cavernoma.
Thrombolytic therapy may
recanalize occluded pulmonary arteries, but it may lyse floating thrombus into small fragments causing additional occlusion of patent pulmonary artery and exacerbation of pulmonary hypertension.
In the study, patients diagnosed with AIS (as confirmed by radiographic assessment) were treated with the Solitaire FR device In order to reopen, or
recanalize, the blocked blood vessels.
