Isolated superior mesenteric artery dissection (ISMAD) is a rare but potentially life-threatening condition that causes acute abdominal pain. It refers to a dissection that occurs solely in the superior mesenteric artery (SMA), typically spontaneously, and does not involve the aorta . [ 1 ]
SMA syndrome is also known as Wilkie's syndrome, cast syndrome, mesenteric root syndrome, chronic duodenal ileus and intermittent arterio-mesenteric occlusion. [3] It is distinct from nutcracker syndrome , which is the entrapment of the left renal vein between the AA and the SMA, although it is possible to be diagnosed with both conditions.
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.
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
Carotid artery disease can be typically addressed with open surgical techniques (carotid endarterectomy) or though endovascular stenting. Chronic mesenteric ischemia can produce severe pain with eating and result in food fear and weight loss. These vascular disorders can be repaired by endovascular approaches using angioplasty and stenting.
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 ...
Interventional pain management or interventional pain medicine is a medical subspecialty defined by the National Uniforms Claims Committee (NUCC) as, " invasive interventions such as the discipline of medicine devoted to the diagnosis and treatment of pain related disorders principally with the application of interventional techniques in managing sub acute, chronic, persistent, and intractable ...
The covered stent is composed of metal and is covered with Teflon (PTFE) or another sterile fabric-like material. The covered stent remains in place permanently, and the pseudoaneurysm, without a continuous flow of arterial blood, then thromboses. Advantages of this technique are that it has a high success rate without the need for an open surgery.
