Retrograde motion or flow signifies a backward, reverse, or contrary direction to the usual. In astronomy, this term is used to describe the apparent backward movement of planets as observed from Earth, a phenomenon that occurs due to the relative positions and movements of Earth and the other...
The antegrade flow is greater than the retrograde flow. A retrograde valve may be included which provides a controllable retrograde and antegrade flow along the exterior of the catheter body. When a retrograde valve is used, the retrograde flow is greater than the antegrade flow....
Objectives- of this study was to evaluate effects of retrograde filling on the patency of significant (high-grade, >90%) coronary arterial stenosis.Methods- The basis of our study was a comparison between the first and the second angiography of 102 patients with at least a 3-month interval ...
Case 10 In this case, both vessels have antegrade flow, and the pulmonary artery is thinner than the aorta (Figure 15). 病例10。本病例中,两血管同为前向血流,且肺动脉内径小于主动脉弓(图15)。 dictsearch.appspot.com 10. Experimental study of cerebral protection by retrograde vs selective antegr...

The preoperative blood flow was measured at 258.44 ± 76.31 ml/min, while the postoperative blood flow was measured at 672.19 ± 143.84 ml/min. 31 patients had hypertension, and 33 patients had diabetes. The most common site of stenosis was mixed site. Except for stenosis site,...
Deep hypothermic circulatory arrest (DHCA) without brain perfusion does not meet the minimum cerebral blood flow demand and retrograde cerebral perfusion is not consistent with the physiological situation. However, antegrade cerebral perfusion (ACP) is physiological and the most widely used approach of...
After initiation of the circulatory arrest period, all aortic arch pathology was resected. The open arch was routinely inspected for the presence of retrograde flow coming from the ostia of the left common carotid and subclavian arteries to verify the presence of antegrade cerebral perfusion via the...
This is the first report of cerebral blood flow measurement with transcranial Doppler (TCD) during aortic arch reconstruction using continuous retrograde cerebral perfusion (CRCP) with deep hypothermia. Cerebral blood flow velocity was m... H Sakahashi,A Hashimoto,S Aomi,... - 《Nihon Kyobu Geka...
