Spontaneous Dissection

AbstractIsolated spontaneous dissection of the mesenteric artery in the absence of involvement of the aorta or its branches is an uncommon vascular entity. It is generally seen in males and presents with gastrointestinal symptoms due to mesenteric ischemia. However, asymptomatic cases are increasingly being diagnosed due to increased use of computed tomography (CT) angiography. The course is usually self-limiting, and conservative management with bowel rest, strict blood pressure control, anticoagulants, sedatives for pain, and close observation usually suffices. Surgery or endovascular stenting is usually reserved for those exhibiting bowel ischemia or impending rupture. We report a case of a young female with isolated spontaneous mesenteric artery dissection with thrombus, which did not improve with medical therapy and was managed promptly by surgery due to the presence of bowel ischemia.

A true isolated superior mesenteric artery (SMA) dissection is a rare occurrence. The increasing use of diagnostic imaging studies has resulted in this rare disease being more recognized. A 68-year-old Caucasian female presented with sharp upper abdominal pain. Computed tomography (CT) of the abdomen showed dissection with thrombosis in the proximal SMA. Conservative management with bowel rest, blood pressure control, and anticoagulation relieved her symptoms. Follow-up CT showed stable dissection. Physicians should consider the diagnosis of isolated spontaneous SMA dissection after excluding more common causes. The optimal management pathway has not been firmly established. Conservative management with anticoagulation appears to be a safe first-line therapy in selected patients.

Superior Mesenteric Artery Dissection

Objective: To summarize the reproducible experience obtained during the treatment of superior mesenteric artery dissection (SMAD) and to investigate the therapeutic options for this condition. Methods: The clinical data from 10 patients with SMAD were retrospectively analyzed, including 6 patients receiving conservative therapy, 2 patients receiving endovascular stenting, 1 patient receiving dissecting aneurysm resection plus vascular prosthesis grafting, and 1 patient receiving thrombectomy plus intimectomy. Results: For the 6 patients subjected to the conservative therapy, the symptoms were thoroughly under control without relapse during the follow-up; for the 2 patients receiving endovascular stenting, the computed tomography (CT) examination performed during the follow-up demonstrated a patent true lumen and an occluded false lumen; for the patient with dissecting aneurysm resection plus vascular prosthesis grafting, a short dissection was observed at the distal end of the vascular prosthesis but without progression during the 14-month follow-up period; for the patient with thrombectomy plus intimectomy, postoperatively, the patient experienced diarrhea, body weight loss, and hypoproteinemia, and CT scanning demonstrated segmental SMA occlusions, which were not fully remitted by conservative therapy until the application of endovascular stenting 4 months later. Conclusions: The therapeutic regimen for isolated SMAD should be established based on the clinical symptoms of the patient and the hemodynamic status in SMA. The conservative therapy is mainly indicated for the asymptomatic patients or those with short-term symptoms, while the endovascular or surgical therapy should be recommended for those with persistent intestinal ischemia-related symptoms, rupture of artery, and/or obvious aneurysmal false lumen dilation at a high risk of rupture.

Background and Aims: There are increasing reports on case series on spontaneous isolated mesenteric artery dissection, that is, dissections of the superior mesenteric artery and celiac artery, mainly due to improved diagnostic capacity of high-resolution computed tomography angiography performed around the clock. A few case–control studies are now available, while randomized controlled trials are awaited. Material and Methods: The present systematic review based on 97 original studies offers a comprehensive overview on risk factors, management, conservative therapy, morphological modeling of dissection, and prognosis. Results and Conclusions: Male gender, hypertension, and smoking are risk factors for isolated mesenteric artery dissection, while the frequency of diabetes mellitus is reported to be low. Large aortomesenteric angle has also been considered to be a factor for superior mesenteric artery dissection. The overwhelming majority of patients can be conservatively treated without the need of endovascular or open operations. Conservative therapy consists of blood pressure lowering therapy, analgesics, and initial bowel rest, whereas there is no support for antithrombotic agents. Complete remodeling of the dissection after conservative therapy was found in 43% at mid-term follow-up. One absolute indication for surgery and endovascular stenting of the superior mesenteric artery is development of peritonitis due to bowel infarction, which occurs in 2.1% of superior mesenteric artery dissections and none in celiac artery dissections. The most documented end-organ infarction in celiac artery dissections is splenic infarctions, which occurs in 11.2%, and is a condition that should be treated conservatively. The frequency of ruptured pseudoaneurysm in the superior mesenteric artery and celiac artery dissection is very rare, 0.4%, and none of these patients were in shock at presentation. Endovascular therapy with covered stents should be considered in these patients.

Abstract Background Most patients with isolated superior mesenteric artery (SMA) dissection are successfully managed conservatively. However, some patients require more invasive treatment. Case presentation We herein describe a 45-year-old man with isolated SMA dissection. He initially underwent conservative treatment. However, because of persistent abdominal angina, we considered the need for surgical revascularization. He was successfully treated by endarterectomy, patch angioplasty, and retrograde open mesenteric stenting. The abdominal angina was stabilized thereafter. Conclusions The combination of endarterectomy, patch angioplasty, and retrograde open mesenteric stenting is useful for isolated SMA dissection, and long patency can be expected for some patients.

Nonatherosclerotic spontaneous coronary artery dissection (NA-SCAD) is an uncommon cause of myocardial infarction. It most commonly affects females in the perimenopausal age. NA-SCAD has been associated with many predisposing factors including pregnancy and hormonal therapy for both contraception and ovulation induction. The presented case is a previously healthy 41-year-old woman diagnosed with inferior ST-elevation myocardial infarction due to right descending coronary artery dissection associated with recent use of clomiphene monotherapy for ovulation induction (a previously fertile woman), which was not previously reported. Learning Objectives. Emergency physicians (EPs) should be aware about NA-SCAD as a cause of acute coronary syndrome (ACS) especially in perimenopausal women even with no risk factors. NA-SCAD occurs more commonly in the postpartum period and in females following hormonal therapy. Here, clomiphene monotherapy was reported as a possible contributing factor to NA-SCAD. Guidelines for NA-SCAD management are not up to date, and EPs should avoid some interference before the final diagnosis of the cause of myocardial infarction.
