What is a retroaortic left renal vein?

What is a retroaortic left renal vein?

Common variant: The left renal vein drains the left kidney into the inferior vena cava (ivc). To get there, it has to go around the aorta. Most often, this path is in front of the aorta. Less commonly, it passes behind (retro aortic). This is of no significance unless surgery in that area is necessary, in which case it's helpful for the surgeon to know ahead of time.

What is an incidental retroaortic left renal vein? The key term here would be "incidental" as it appears that something caused it to be retroaortic

What is an incidental retroaortic left renal vein? The key term here would be "incidental" as it appears that something caused it to be retroaortic

Normal finding.: The left renal vein which comes off the inferior vena cava normally crosses in front of the aorta and not behind it in the usual anatomy. In about 5% of people the left renal vein will pass behind the aorta (retro aortic). This is a normal anatomic variation and normal for that person. It is usually identified on ct.

Need help understanding CT of abdomen... Liver: portal vein is patent, retroaortic left renal vein, a normal variant. Can it be caused from injuries?

Need help understanding CT of abdomen... Liver: portal vein is patent, retroaortic left renal vein, a normal variant. Can it be caused from injuries?

Vascular: This is a normal finding. Most left renal veins cross anterior to the aorta. A retrospective vein means it crosses behind the aorta to drain into the inferior vena cava. It is of no clinical significance to you unless you have certain surgeries in the future.

Incidental note of a circumaortic left renal vein, crosses the midline. Definition please?

Incidental note of a circumaortic left renal vein, crosses the midline. Definition please?

Anatomical variant: Normally, the left renal vein crosses over the aorta and drains into the vena cava. A circum-aortic left renal vein is simply a vein that crosses both above and behind the aorta. It's not a problem in the least and could only cause a vascular surgeon an issue in an open aortic operation if he wasn't aware of it. So no problem! You can still call the hogs! Wps!

Mildlynprominent retroperitoneal lymph nodes largest measuring 1.8 by 1.1 centimeters to the left renal vein does this sound like cancer?

Mildlynprominent retroperitoneal lymph nodes largest measuring 1.8 by 1.1 centimeters to the left renal vein does this sound like cancer?

Prominent nodes: These findings are borderline and nonspecific. In the absence of other pathology, enlarged lymph nodes in other areas of the body or enlargement of liver or spleen, this may be insignificant. I feel your physician should review the study with the radiologist and describe any symptoms you might have and obtain recommendations for any other studies or specialty referrals advised by the radiologist

An MRA confirmed that I have nutcracker syndrome in my left renal vein and right hepatic artery arising from the proximal Superior mesenteric artery. Could this be the cause of my uncontrolled BP &HR?

An MRA confirmed that I have nutcracker syndrome in my left renal vein and right hepatic artery arising from the proximal Superior mesenteric artery. Could this be the cause of my uncontrolled BP &HR?

Yes: Limitation of blood flow to a kidney will typically raise BP. Often in such a case the BP will be very difficult to control with meds unless the blood flow is restored. A stent in the renal artery may help, but there are several studies suggesting that if meds can control the BP, then procedural risks may not be warranted. You should consult with a vascular surgeon or interventional radiologist.

Went to the ER for gallstone pain the radiologist spotted Nutcracker syndrome/ left renal vein entrapment syndrome. Can a vascular surgeon use this CT?

Went to the ER for gallstone pain the radiologist spotted Nutcracker syndrome/ left renal vein entrapment syndrome. Can a vascular surgeon use this CT?

Imaging: A contrasted CT is better than a non-contrasted CT for NCS. Make a CD of the images and see a vascular surgeon. Your surgeon will decide what kind of imaging they need to help you decide what to do.

How can a big left sided varicocele (grade 3) increase pressure to right renal vein and cause some pain in right testis? (anatomical question)

How can a big left sided varicocele (grade 3) increase pressure to right renal vein and cause some pain in right testis? (anatomical question)

Unlikely: Varicoceles are common in adolescents 7-15 %. 95% occur on the left side only. This condition is usually without symptoms of discomfort. A grade 3 varicocele may be considered for repair as they can lead to low sperm counts and infertility. If your symptoms are on the right side you should see a PCP or urologist to assess further

Can you die from renal vein transposition surgery?

Can you die from renal vein transposition surgery?

Surgery risks: There is always a death when surgery is involved and how high that risk is depends on the type of surgery and anesthesia needed. Talk to your surgeon and he will have that information for you.

Can renal vein thrombosis be cured?

RVT: It all depends upon the cause. If the cause is cancer then successful treatment of the cancer should "cure" the rvt. If the cause is a disease in the kidney (eg. Most notably a disease called mebranous glomerulopathy) then it is not likely that there will be a "cure" since this form of kidney disease has no known "cure". Anticoagulation can help to prevent worsening of the problem.

Is there a cure for renal vein thrombosis?

No: Need to find underlying cause of thrombosis to prevent recurrence of thrombosis. May need anticoagulation to prevent recurrence.

What is the pathway of the blood from the renal artery to the renal vein?

Like: For any other organ / tissue the arteries bring blood, in this case the large renal artery, with oxygen and the waist products and splitsin the kidney into smaller and smaller branches that become eventually capillaries that connect with the venous capillaries that join biger end bigger vessels ending in the large renal vein, a branch of the vena cava that will end in the right heart.

What causes a renal vein thrombosis?

Predisposition: Spontaneous thrombosis of a non peripheral vien suggests a possibility of underlying predisposition for clotting. Evaluation of protein c, protein s activities, d dimer, factor x and cardolipin and phosphlpid antibodies should be evaluated. All to say a fell hemotolaogic workup is necessary. If these abnormaitie exist consider smoking birthcontrol cancer as underlying triggers.

What is the definition or description of: renal vein thrombosis?

What is the definition or description of: renal vein thrombosis?

Occlussion: Renal vein thrombosis means occlussion of the vein draining the kidney. The vein is occluded by clot. It typically occurs in the left renal vein. It may be caused by trauma, cancer, extrinsic compression or from a hypercoagulable state.

What to do if I have a question regarding the composition of the blood in the renal artery vs the renal vein?

What to do if I have a question regarding the composition of the blood in the renal artery vs the renal vein?

What is the question: The renal artery carries blood to be filtered by the kidney. Thus, it can have differences in electrolytes, metabolites, and other substances. The kidney filters the blood, and "resets" the electrolytes. It may also remove some substances into the urine. Also, the renal vein will have less oxygen than the artery.

Do people with renal vein thrombosis have a lot of pain?

Do people with renal vein thrombosis have a lot of pain?

RVT: The presentation of renal vein thrombosis (rvt) is variable, and patients may be asymptomatic. When rvt occurs as a result of malignancy, the signs of the renal malignancy (eg, bloody urine, weight loss) predominate. The more common chronic form of rvt is generally has no symptoms. The less frequent acute form usually occurs in younger patients, with flank pain and visible blood in the urine, wh.
