title: [The diagnosis and treatment of isolated celiac and superior mesenteric artery dissection: 2 cases report and literature review].
abstract: OBJECTIVE
  To investigate the diagnosis and treatment of isolated celiac artery (CA) dissection and superior mesenteric artery (SMA) dissection.
  
  
  METHODS
  Integrating clinical data of 119 cases with isolated dissection of the visceral arteries (IDVA) reported in literature and 2 patients with spontaneous isolated dissections of both CA and SMA treated in the Third Affiliated Hospital of Sun Yat-sen University, the diagnosis and treatment of IDVA were analyzed retrospectively.
  
  
  RESULTS
  Among 119 cases reported in the literature, 69 cases were symptomatic. All of the cases were diagnosed by contrast-enhanced abdominal CT or MRI. After IDVA was discovered, surgical treatment and endovascular stent placement was performed in 8 and 5 patients respectively, although the remaining 106 patients were managed conservatively with good results. In our 2 cases, the diagnosis of CA and SMA dissection was established by contrast-enhanced CT and confirmed by conventional angiography. One patient was treated with anticoagulation and antihypertension, and the other patient was treated with endovascular stenting. Both of the patients didn't have discomfort during the follow-up period of 12 and 3 months respectively.
  
  
  CONCLUSIONS
  Contrast-enhanced abdominal CT is the main tool for detection of IDVA. Most of the patients with IDVA can be managed conservatively, but close surveillance with imaging studies is necessary for early recognition of dissection progression. Patients with persistent or relapsed symptoms, and dissection progression, should undergo surgical or endovascular treatment.
