Abstract Arterial leiomyosarcoma (A-LMS) is a very rare tumour and no cases originating from the superior mesenteric artery (SMA) have been described. We present a case of A-LMS originating from distal part of SMA and incorporating superior mesenteric vein (SMV). SMA and SMV were prepared along their course by laparotomy. Prior to resection, the superior mesenteric vessels were clamped, and intra-operative infrared angiography after intravenous injection of indocyanine green was performed. Once confirmed the vitality of the bowel, mass resection including the distal portion of the SMA and SMV was executed. The postoperative course was uneventful. Histology confirmed initial diagnosis. Six months after surgery no recurrence was highlighted. This is the first case of A-LMS originating from SMA, successfully treated without any intestinal resection or vascular reconstruction. The use of near-infrared angiography associated with a preoperative angiographic workup is indispensable for the success of the surgery.

Mini Laparotomy

Superior mesenteric artery aneurysm (SMAA) is reported to be the third-most common type of visceral aneurysm (VA), accounting for 5% of all VAs. The etiology of SMAA is commonly thought to be infection, and it usually exists in the proximal part of the superior mesenteric artery, which is suitable for endovascular treatment. We herein report an extremely rare case of the distal part of SMAA caused by Takayasu's arteritis (TA), which was successfully resected using a mini-laparotomy method without impairing the intestinal blood supply. A 51-year-old woman was admitted to our hospital with sustained fever and lower back pain. Physical examination showed that she had a discrepancies in blood pressure between both arms. Contrast-enhanced whole-body computed tomography showed stenosis of the thoracic aorta and an aneurysm located in the distal part of the superior mesenteric artery. The diameter of the aneurysm was 4.5 cm. The aneurysm was resected via 4-cm mini-laparotomy, and the vascularity of the intestine was successfully preserved. The postoperative course was uneventful, and the patient was diagnosed as having TA based on both clinical and pathologic findings. Additional corticosteroid therapy was started to treat the arteritis, and at 3-month follow-up she was without critical incidents. Mini-laparotomy is a safe and less-invasive approach to treat SMAA, especially when the lesion is located in the distal part of the artery.

Prompt Diagnosis

Traumatic injuries to the mesenteric vessels are rare and often lethal. Visceral vessels, such as the superior mesenteric artery (SMA) and vein (SMV), supply blood to the small and large bowel by a rich system of collaterals. Because fewer than 100 such injuries have been described in the literature, they pose challenges in both diagnosis and management and can unfortunately result in high mortality rates. Prompt diagnosis, surgical intervention, and resuscitation can lead to improved outcomes. Here, we review the literature surrounding traumatic injuries of the SMA/SMV and discuss management strategies.

The hypothesis that escape from norepinephrine-induced vasoconstriction in the intestine is due to relaxation of initially constricted vessels was tested in 18 anesthetized cats. Intestinal blood flow was measured by an electro magnetic probe on the superior mesenteric artery. Intestinal submucosal and muscle arterioles and small mesenteric arteries were studied by in vivo microscopy with an image-splitting technic. Continuous recordings of mesenteric flow and vessel diameter were made during the infusion into the superior mesenteric artery of norepinephrine (NE) at a rate of 1-2 mug/min for 3 min. Mesenteric flow decreased soon after the NE infusion began but then escaped. Microscopically, arterial constriction and escape were noted in submucosal, muscle, and mesenteric vessels with a time course similar to that for flow. Arteriovenous anastomoses were not seen. These findings support the hypothesis that escape from Ne-induced vasoconstriction is due to relaxation of initially constricted vessels.

Abstract Background:Acute superior mesenteric artery embolism is a life-threatening disease and the prognosis is very poor. Few reports have described the application of Percutaneous Mechanical Thrombectomy in Acute superior mesenteric artery embolism. In the article, we show a series of cases treated with Percutaneous Mechanical Thrombectomy and share our experience.Methods:Review and analyze seven patients with acute superior mesenteric artery embolism treated by Angiojet Ultra thrombectomy system in our institution. Based on the literature, we summarize the diagnosis, treatment and surgical experience of acute superior mesenteric artery embolism. Results:Percutaneous Mechanical Thrombectomy were achieved successfully in all the patients without surgical complication occurred. Five patients’ symptoms relieved significantly and smoothly discharged from the hospital. Two patients still complained of abdominal pain after operation. One patient underwent surgical laparotomy and intestinal resection and the other one abandoned surgical treatment. During the first six months of follow-up, six patients were free of any clinical symptoms or signs and one patient who refused laparotomy died two days later with septic shock.Conclusion:Percutaneous Mechanical Thrombectomy by Angiojet Ultra thrombectomy system is a safe, effective and minimally invasive method in the initial stage of acute superior mesenteric artery embolism. We believe Percutaneous Mechanical Thrombectomy could be a promising alternative in selected cases. Furthermore, large sample data and long term follow-up are needed to verify its effect.

Respiratory Management

Abstract The COVID-19 disease caused by novel Coronavirus was first reported in Wuhan, China in December 2019 with 5% patients having severe lung injury. Though this disease primarily presents as a lower respiratory tract infection, multiple digestive manifestations have been reported which are often overlooked. The present case report describes the unusual progression of COVID-19 disease from pneumonia to a procoagulant state leading to superior mesenteric artery thrombosis and subsequent gut ischemia necessitating emergency laparotomy. Coagulopathy in COVID-19 is due to an imbalance in the coagulation homeostasis with increase in thrombocytes in contrast to thrombocytopenia documented in cases of dissemination intravascular coagulation and sepsis. Early recognition of abdominal symptoms, diagnosis of pathology and timely surgical intervention may definitely improve outcome. In the management of any patient with COVID-19 disease, we advocate a comprehensive integrated approach with early recognition of digestive symptoms and their timely intervention which should run parallel to the respiratory management.

Artery Embolism

Percutaneous mechanical thrombectomy is a safe and effective treatment for addressing thrombosis in various embolic diseases. In recent years, this approach has also been actively applied in the management of acute embolic occlusion of the superior mesenteric artery. A pseudoaneurysm as a complication of this operation is remarkably rare. This is the first case report of the diagnosis and treatment of a pseudoaneurysm that developed as a complication after the application of percutaneous mechanical thrombectomy via an AngioJet device for thrombolysis in the superior mesenteric artery.
