It refers to a dissection that occurs solely in the superior mesenteric artery (SMA), typically spontaneously, and does not involve the aorta. [1] Although aortic dissection can frequently extend into its peripheral territories, it is rare for these branches to have dissection without main aortic trunk involvement. The SMA is the most common ...
Superior mesenteric artery compressing the duodenum, featuring the superior mesenteric artery syndrome. Superior mesenteric artery (SMA) syndrome is a gastro-vascular disorder in which the third and final portion of the duodenum is compressed between the abdominal aorta (AA) and the overlying superior mesenteric artery.
This can result in pelvic pain and also GI tract irritation leading to bloating, abdominal fullness, constipation and/or diarrhea. Often times nutcracker syndrome occurs alongside other abdominal compressions such as May Thurner Syndrome, Superior Mesenteric Artery Syndrome, and Median Arcuate Ligament Syndrome.
Abdominal angina is caused by obstruction or stenosis of the inferior mesenteric artery, celiac trunk, or superior mesenteric artery. Gender, age, smoking, hypertension, diabetes, and hyperlipidemia are risk factors for abdominal angina. The digestive tract relies on the celiac, superior mesenteric, and inferior mesenteric arteries for blood ...
The remaining ileum, which is of varying length, survives on a single mesenteric artery, which it is twisted around in a spiral form. [1] The term apple-peel intestinal atresia is generally reserved for when it affects the jejunum, [10] [11] while Christmas tree intestinal atresia is used if it affects the duodenum. It may affect both, however.
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
In embolic acute intestinal ischemia, CT-Angiography can be of great value for diagnosis and treatment. It may reveal the emboli itself lodged in the superior mesenteric artery, as well as the presence or absence of distal mesenteric branches. [18] Late findings, which indicate dead bowel, include: Intramural bowel gas [29] Portal venous gas
Types of mesenteric ischemia are generally separated into acute and chronic processes, because this helps determine treatment and prognosis. [ 3 ] Bowel obstruction is most often caused by intestinal adhesions , which frequently form after abdominal surgeries, or by chronic infections such as diverticulitis , hepatitis , and inflammatory bowel ...
