Internal carotid artery

peripherally administered TPA (tissue plasminogen activator). However, Dr. Philips documented Dr. Kilpadikar called with the result of the CT and stated that there appeared to be a hyperdense MCA (middle cerebral artery) sign. Dr. Philips documented with those findings, Mr. Green did meet relative contraindication for peripheral TPA. Therefore, Dr. Phillips documented while at the bedside, he discussed these findings with Mr. Green and his sister. Dr. Phillips documented Mr. Green remained hemiplegic on the left side with an elevated stroke scale score and his symptoms had worsened. Mr. Green’s NIHSS (National Institutes of Health Stroke Scale) score was an 8. Dr. Phillips documented after discussing peripheral TPA, he decided that a CT angiogram would still be performed since Mr. Green was a good candidate and had significant deficits. Dr. Phillips documented he waived labs and sent Mr. Green for a CT angiogram. Dr. Phillips documented he discussed the images of the CT angiogram with Dr. Scheffner. Dr. Phillips documented Dr. Scheffner stated that the MCA was actually not hyperdense, both carotid arteries appeared occluded at their bases and that Mr. Green’s blood flow seemed to be primarily based off of his vertebral arteries with some collaterals from the carotid. Dr. Phillips documented with these findings, Mr. Green was not an IR (interventional radiology) candidate. Dr. Phillips documented he discussed those findings with Mr. Green and told Mr. Green his only option…

superior and inferior. Next we have the right atrium, from the right atrium the flows through the tricuspid valve. Upcoming the blood flow goes through the right ventricle, to the pulmonary valve, succeeding to the pulmonary artery than to the right and left lung. On the left side of the heart we have pulmonary veins the blood flow continues to the left atrium, through the bicuspid valve. The following the blood goes through the left ventricle to the aortic valve, than to the aorta, to the rest…

Title Anatomical variation of the superior thyroid artery and its relation to the external laryngeal nerve. Introduction The thyroid gland is the largest endocrine gland located in the anterior triangle of the neck. It consists of two lobes, right and left, connected by an isthmus in the middle. The thyroid gland is mainly supplied by the superior thyroid artery, the first branch of the external carotid artery, and the inferior thyroid artery, a branch of the thyrocervical trunk of the…

bring blood to the head, neck, and arms. Innominate artery, sometimes referred as brachiocephalic trunk begins at aortic arch (second branch) and ends at the carotid bifurcation. Innominate artery travels upward and give rise to the right subclavian artery and the right common carotid artery. It supplies blood to the right arm, head, and neck. Right Subclavian artery and Left subclavian artery, On the left side of the body the subclavian comes directly from the aortic arch and ends at the…

The vertebral and the carotid artery nourish a collection of blood vessels called the circle of Willis. The carotid artery supplies blood to most of the cerebral hemispheres. It runs up the lateral sides of the neck, then splits into the anterior cerebral artery and the middle cerebral artery. The anterior cerebral artery supplies blood to the medial surface of the frontal and parietal lobes as well as the corpus callosum. The middle cerebral artery supplies the lateral portions of the…

Brain aneurysms are also referred to as a cerebral aneurysm or intracranial aneurysm. There are four major blood vessel s that supply blood to the brain, two carotid arteries and two vertebral arteries. These blood vessels join together to form the Circle of Willis at the base of the brain, smaller arteries leave the circle and branch out to supply brain cells with oxygen and nutrients. The artery junction points may become weak, as the artery wall becomes thinner from dilation, the blood flow…

guarantee that the far wall intima–media thickness will be correctly measured (90_ angle between ultrasound array and arterial wall). A poorly visualized near wall may indicate a non-optimal imaging view. Furthermore the leading edge of the near wall intima–lumen interface is used when measuring lumen diameter (see below and Fig. 4). The leading edge echo from the lumen–intima interface and from the media–adventitia interface of the far wall can be recorded for the common carotid artery and…

Arterial system of frog Blood vessels, which carry oxygenated blood away from heart to different part of the body, are called arteries. They constitute a system called arterial system. Truncus arterious gives two branches right aortic trunk and left aortic trunk. Each aortic trunk again divides into three branches- a) Carotid arch: it divides into – Lingual artery – it supplies blood to tongue and hyoid. Common carotid – it supplies blood to buccal cavity and brain. it consists swelling at the…

Homeostasis is a key factor in helping the body to maintain optimum conditions for life. It aids in keeping a steady environment inside the body when the external environment is constantly changing. ( Peate, I. and Nair, M. 2011) Humans need to maintain a near constant environment internally to be able to function and to survive. There are various control systems at work in the process of homeostasis, such as negative feedback and the receptor, controller and effector loop. The receptor,…

Jugular Veins The most accessible veins for examination are the internal and external jugular veins in the neck. Both veins drain bilaterally from the head and neck into the superior vena cava. The external jugular vein lies superficially and is just above the clavicle. The internal jugular vein lies deeper, along the carotid artery. It is best to examine the right internal jugular vein because it follows a more direct anatomical path to the right atrium of the heart. The column of blood inside…
