Vascular disorders of intestine (K55)
Clinical Information
Superior Mesenteric Artery Syndrome - DUODENAL OBSTRUCTION by the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) which travels in the root of the MESENTERY and crosses over the DUODENUM. The syndrome is characterized by the dilated proximal duodenum and STOMACH, bloating, ABDOMINAL CRAMPS, and VOMITING. Often it is observed in patient with body casts after spinal surgery.
Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- necrotizing enterocolitis of newborn P77
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
