The existence of retrograde flow in the pulmonary artery was investigated, suggestive of PDA;
A new injection of contrast into the native left coronary trunk showed the absence of retrograde flow through the LMA towards the LSA.
Retrograde flow of urine from the bladder into the upper urinary tract is an anomalous event in human beings known as vesicoureteral reflux VUR.
Reflux in superficial veins was defined as retrograde flow if reflux time was greater than 500 ms.
In the case of retrograde flow to the anastomosis, the coronary surface was measured under the same conditions and the ratio between them considered.
The echocardiography with color-flow mapping showed residual pulmonary flow and retrograde flow in vene cave Figure 3.
In most cases, it is secondary to retrograde flow of gastric contents into the laryngopharynx, resulting in a series of laryngeal signs and symptoms.
It is believed that the involvement of the central nervous system CNS occurs by means of retrograde flow through the Batson venous plexus, which is valveless.
Another author believes that during the retrograde flow vomit, there is a reflex preventive apnea, which remains during the entire retrograde pressurization.
The interaction of myosin with the actin network then generates membrane retraction/ruffling, retrograde flow, and contractile forces for forward motion.
Gastroesophageal reflux occurs when there is involuntary retrograde flow of gastric contents into the esophagus, which can de defined as infant regurgitation or gastroesophageal reflux disease GERD.
Most valvular heart disease can cause valvular stenosis with obstruction to anterograde flow, valvular failure with retrograde flow, or both 1.
In this series, only two 2.5% patients had unsatisfactory retrograde flow with the necessity to change the site of arterial cannulation.
The normal physiological blood flow is anterograde, flowing from the periphery towards the heart, so thatthe evidence of an opposite, retrograde flow might indicate a pathology.
The retrograde flow can pass through the interarytenoid space or penetrate at the level of the laryngeal vestibule and trigger episodes of defensive apnea abrupt and intense reflex closure of the glottis.
There is also incompetence in the gastrocnemius muscle pump calf muscle, because the venous pressure, during walking or exercise, does not occur,resulting in retrograde flow.
Thus, the increase in oxygen consumption determined by exertion in the left upper limb stimulated retrograde flow through the mammary artery, thus reducing distal perfusion of the left anterior descending artery.
Aneurysms of the ophthalmic segment paraclinoid can also be treated by ICA occlusion, but the chances of thrombosis are smaller,especially due to the presence of the retrograde flow through the ophthalmic artery.
Normal flow was defined as anterograde, andreflux was defined as retrograde flow with a duration of 0.5 seconds after a Valsalva maneuver or manual compression and decompression of the distal portion of the limb.
If the injection is continued after flow has ceased within the aneurysm sac,there is a greater risk of thrombosis of the native artery caused by retrograde flow, exposing the artery to thrombin.
However, it is known that the use of Doppler has made the examination more sensitive in demonstrating the retrograde flow through the valve, even when there is no clinical repercussion, facilitating early diagnosis of aortic regurgitation.
The patient underwent aneurysm resection and interposition reverse saphenous vein graft in brachial-radial location, with ligation of the ulnar branch,since there was a significant retrograde flow through this branch Figures 2 and 3.
The selective injection of contrast into the left coronary artery opacified the left subclavian artery via retrograde flow of contrast through the ipsilateral mammary artery and slow flow with slight distal opacification of the anterior descending branch after anastomosis.
Personally, in cases of recurrent stenosis due to atheromatous plaque, we use conventional access, avoiding direct dissection of the distal portion of the internal carotid artery,before obtaining control of retrograde flow using a Fogarty catheter.
Leaks can be classified into five types, the most common of which is type 2. A type 2 leak is the result of retrograde flow into the aneurysm sac from aortic branches and as such is unrelated to the prosthesis itself.
At peak stress, the flow in the AITA became exclusively diastolic, with coronary flow reserve index of 1.8 Figure 2A and 2B, indicating good functional status,while the LVA remained entirely with retrograde flow Figure 2C and 2D.
The mechanism is probably due to the embolization of the retinal arterioles,which suffer this injury due to retrograde flow of anastomoses between the anterior and posterior ethmoidal arteries and the ophthalmic artery.
Using pulsed Doppler was possible to measure the velocities of peak venous blood flow in the right superior pulmonary vein RSPV, called S-waves, D and A. The S wave indicated the systolic forward flow, the D wave, the diastolic antegrade flow, and A wave, retrograde flow during atrial contraction.
The Brazilian Consensus in Gastroesophageal Reflux Disorder CBDRGE defined GERD as a chronic disease arising from the retrograde flow of the gastro-duodenal content to the aesophagus and/or adjacent organs, causing a variable spectrum of esophageal and extraesophageal signs and symptoms, with or without tissue lesions.
In this technique variation, the pulmonary trunk is sutured to the aortic arch after the junction of the innominate artery and may cause, when the ascending aorta hasa very small diameter, inadequate retrograde flow to the coronary arteries through the ascending aorta.
