A 78-year-old patient with known cutaneous progressive T-cell lymphoma and hypertension was referred to our institution in August 2013. During hospitalisation the patient became somnolent and developed elevated infection parameters. Abdominal ultrasonography showed a pulsating abdominal mass and CT examination revealed a stretched pancreas and an underlying partial thrombosed juxtarenal AAA extending distally to the origin of the superior mesenteric artery (SMA) and the aortic bifurcation without signs of visceral malperfusion elsewhere. The Ductus pancreaticus was dilated without involvement of the head. There were no additional radiological findings of occupying character other than the AAA. Because of his advanced age, increasing inflammatory parameters, and cutaneous T-cell lymphoma the patient was at this point neither suitable for open AAA surgery nor endovascular treatment. -

Everything I Need to Know About Renal Artery Stenosis
Patient Information Renal Services Everything I need to know about renal artery stenosis What is renal artery stenosis? Renal artery stenosis is the narrowing of the main blood vessel running to one or both of your kidneys. Why does renal artery stenosis occur? It is part of the process of arteriosclerosis (hardening of the arteries), that develops in very many of us as we get older. As well as becoming thicker and harder, the arteries develop fatty deposits in their walls which can cause narrowing. If the kidneys are affected there is generally also arterial disease (narrowing of the arteries) in other parts of the body, and often a family history of heart attack or stroke, or poor blood supply to the lower legs. Arteriosclerosis is a consequence of fat in our diet, combined with other factors such as smoking, high blood pressure and genetic factors inherited, it may develop faster if you have diabetes. What are the symptoms? You may have fluid retention, where the body holds too much water and this can cause breathlessness, however often there are no symptoms. The arterial narrowing does not cause pain, and urine is passed normally. As a result this is usually a problem we detect when other tests are done, for example, routine blood test to measure how well your kidneys are working. What are the complications of renal artery stenosis? Kidney failure, if the kidneys have a poor blood supply, they may stop working. This can occur if the artery blocks off suddenly or more gradually if there is serious narrowing. -

This provides necessary food and oxygen to all body cells. The abdominal aorta contains the celiac, superior mesenteric, inferior mesenteric, renal and iliac arteries. It begins at the diaphragm and ends at the iliac artery branching. Unit 2: Definition of Abdominal Aortic Aneurysm Normally, the lining of an artery is strong and smooth, allowing for blood to flow easily through it. The arterial wall consists of three layers. A true aneurysm involves dilation of all three arterial wall layers. Abdominal aortic aneurysms occur over time due to changes of the arterial wall. The wall of the artery weakens and enlarges like a balloon (aneurysm). -

Blood Vessels
BLOOD VESSELS Blood vessels are how blood travels through the body. Whole blood is a fluid made up of red blood cells (erythrocytes), white blood cells (leukocytes), platelets (thrombocytes), and plasma. It supplies the body with oxygen. SUPERIOR AORTA (AORTIC ARCH) VEINS & VENA CAVA ARTERIES There are two basic types of blood vessels: veins and arteries. Veins carry blood back to the heart and arteries carry blood from the heart out to the rest of the body. Factoid! The smallest blood vessel is five micrometers wide. To put into perspective how small that is, a strand of hair is 17 micrometers wide! 2 BASIC (ARTERY) BLOOD VESSEL TUNICA EXTERNA TUNICA MEDIA (ELASTIC MEMBRANE) STRUCTURE TUNICA MEDIA (SMOOTH MUSCLE) Blood vessels have walls composed of TUNICA INTIMA three layers. (SUBENDOTHELIAL LAYER) The tunica externa is the outermost layer, primarily composed of stretchy collagen fibers. It also contains nerves. The tunica media is the middle layer. It contains smooth muscle and elastic fiber. TUNICA INTIMA (ELASTIC The tunica intima is the innermost layer. MEMBRANE) It contains endothelial cells, which TUNICA INTIMA manage substances passing in and out (ENDOTHELIUM) of the bloodstream. 3 VEINS Blood carries CO2 and waste into venules (super tiny veins). The venules empty into larger veins and these eventually empty into the heart. The walls of veins are not as thick as those of arteries. Some veins have flaps of tissue called valves in order to prevent backflow. Factoid! Valves are found mainly in veins of the limbs where gravity and blood pressure VALVE combine to make venous return more 4 difficult. -
Abdominal Aortic Aneurysm
Abdominal Aortic Aneurysm (AAA) Abdominal aortic aneurysm (AAA) occurs when atherosclerosis or plaque buildup causes the walls of the abdominal aorta to become weak and bulge outward like a balloon. An AAA develops slowly over time and has few noticeable symptoms. The larger an aneurysm grows, the more likely it will burst or rupture, causing intense abdominal or back pain, dizziness, nausea or shortness of breath. Your doctor can confirm the presence of an AAA with an abdominal ultrasound, abdominal and pelvic CT or angiography. Treatment depends on the aneurysm's location and size as well as your age, kidney function and other conditions. Aneurysms smaller than five centimeters in diameter are typically monitored with ultrasound or CT scans every six to 12 months. Larger aneurysms or those that are quickly growing or leaking may require open or endovascular surgery. What is an abdominal aortic aneurysm? The aorta, the largest artery in the body, is a blood vessel that carries oxygenated blood away from the heart. It originates just after the aortic valve connected to the left side of the heart and extends through the entire chest and abdomen. The portion of the aorta that lies deep inside the abdomen, right in front of the spine, is called the abdominal aorta. Over time, artery walls may become weak and widen. An analogy would be what can happen to an aging garden hose. The pressure of blood pumping through the aorta may then cause this weak area to bulge outward, like a balloon (called an aneurysm). An abdominal aortic aneurysm (AAA, or "triple A") occurs when this type of vessel weakening happens in the portion of the aorta that runs through the abdomen. -
Fetal Descending Aorta/Umbilical Artery Flow Velocity Ratio in Normal Pregnancy at 36-40 Weeks of Gestational Age Riyadh W Alessawi1
American Journal of BioMedicine AJBM 2015; 3(10):674 - 685 doi:10.18081/2333-5106/015-10/674-685 Fetal descending aorta/umbilical artery flow velocity ratio in normal pregnancy at 36-40 Weeks of gestational age Riyadh W Alessawi1 Abstract Doppler velocimetry studies of placental and aortic circulation have gained a wide popularity as it can provide important information regarding fetal well-being and could be used to identify fetuses at risk of morbidity and mortality, thus providing an opportunity to improve fetal outcomes. Prospective longitudinal study conducted through the period from September 2011–July 2012, 125 women with normal pregnancy and uncomplicated fetal outcomes were recruited and subjected to Doppler velocimetry at different gestational ages, from 36 to 40 weeks. Of those, 15 women did not fulfill the protocol inclusion criteria and were not included. In the remaining 110 participants a follow up study of Fetal Doppler velocimetry of Ao and UA was performed at 36 – 40 weeks of gestation. Ao/UA RI: 1.48±0.26, 1.33±0.25, 1.37± 0.20, 1.28±0.07 and 1.39±0.45 respectively and the 95% confidence interval of the mean for five weeks 1.13-1.63. Ao/UA PI: 2.83±2.6, 1.94±0.82, 2.08±0.53, 1.81± 0.12 and 3.28±2.24 respectively. Ao/UA S/D: 2.14±0.72, 2.15±1.14, 1.75±0.61, 2.52±0.18 and 2.26±0.95.

They took origin from the antero lateral aspect of abdominal aorta, below the origin of superior mesenteric artery and above the origin of main renal arteries. The main right and left renal arteries took their origin from the lateral aspect of abdominal aorta, at the level of the origin of inferior mesenteric artery. Proper knowledge of variations of the arteries supplying the kidney is essential not only to the anatomists but also to the vascular surgeons, urologists, nephrologists and radiologists. Such vascular variations as noted in the present study have been explained in light of embryogenic development.
