Isolated, spontaneous superior mesenteric and celiac artery dissection: case report and review of literature.
Spontaneous, isolated dissection of the superior mesenteric artery (SMA) and celiac artery (CA) is rare. Although there are known risk factors, there is no particular mechanism that is common to vascular dissections. The objectives of this study were to review the current literature on diagnosis and treatment of isolated SMA and CA dissection, and to review aortic complications in giant cell arteritis, Takayasu arteritis, and polyarteritis nodosa. Giant cell arteritis, Takayasu arteritis, and polyarterteritis nodosa are vasculitides that are associated with SMA and CA dissection. An interesting aspect of this case is that the patient was a healthy person before presentation, and ultimately, did not have an underlying etiology to explain the dissection. In addition, the patient was successfully managed without operative intervention. Although there are known risk factors in patients who present with isolated, spontaneous SMA and CA dissection, the pathogenesis is still unclear. The prognosis has improved significantly with the early use of computed tomography angiography to diagnosis this entity. Although most cases require surgical intervention, there are some, as in this case, that are managed non-operatively.
