Acute mesenteric ischemia after cardiac surgery is a serious complication associated with high mortality. Superior mesenteric artery is most commonly affected artery. Acute obstruction of mesenteric artery generally has an unfavorable prognosis because of late diagnosis. The keys to a successful outcome are early diagnosis and appropriate operative intervention. We successfully treated a patient with acute mesenteric ischemia after aortic valve replacement. Therefore, we report a case with a review of articles.

Objective: To investigate the factors influencing small intestinal ischemia in elderly patients with incarcerated hernia. Methods: The clinical data of 105 elderly patients admitted for surgical procedures of incarcerated hernia at Department of General Surgery, Huadong Hospital between January 2014 and December 2021 were retrospectively analyzed. There were 60 males and 45 females, aged (86.1±4.3) years (range: 80 to 96 years). They were divided into normal group (n=55) and ischemic group (n=50) according to intraoperative intestinal canal condition. The t test, χ² test and Fisher's exact probability method were used for the univariate analysis of the factors that influence intestinal ischemia in patients, and Logistic regression was used for multifactorial analysis. Results: In all patients, 18 patients (17.1%) had irreversible intestinal ischemia with bowel resection. Six patients died within 30 days, 3 cases from severe abdominal infection, 2 cases from postoperative exacerbation of underlying cardiac disease, and 1 case from respiratory failure due to severe pulmonary infection. The results of the univariate analysis showed that there were differences in gender, history of intussusception, duration of previous hernia, white blood cell count, neutrophil percentage, C-reactive protein, type of incarcerated hernia, and preoperative intestinal obstruction between the two groups (all P<0.05). The Logistic regression results showed that the short time to the previous hernia (OR=0.892, 95%CI 0.872 to 0.962, P=0.003), high C-reactive protein (OR=1.022, 95%CI 1.007 to 1.037, P=0.003), non-indirect incarcerated hernia (OR=10.571, 95%CI 3.711 to 30.114, P<0.01) and preoperative intestinal obstruction (OR=6.438, 95%CI 1.762 to 23.522, P=0.005) were independent risk factors for the development of intestinal ischemia in elderly patients with incarcerated hernia. Conclusions: The short duration of the previous hernia, the high values of C-reactive proteins, the non-indirect incarcerated hernia, and the preoperative bowel obstruction are influencing factors for bowel ischemia in elderly patients with incarcerated hernia. A timely operation is necessary to reduce the incidence of intestinal necrosis and improve the prognosis.

OBJECTIVETo examine the outcome of damage control surgery (DCS) in patients with acute mesenteric ischemia (AMI).

METHODSClinical data of 15 consecutive AMI cases treated with DCS from May 2001 to March 2009 at the Research Institute of General Surgery, Jinling Hospital were retrospectively analyzed. Eleven patients had acute superior mesenteric vein thrombosis (MVT) on admission, and 4 suffered from acute mesenteric arterial embolism/thrombosis (MAE/MAT). The staged damage control approach included immediate resection of the involved bowel (but no attempts to restore gastrointestinal continuity), open thrombectomy, transfer of the patients to ICU for resuscitation, and thrombolysis prior to the planned definitive reconstructive procedure.

RESULTSOf 15 patients, 10 (66.7%) survived. The mean remnant small bowel length was (209.0+/-53.8) cm (120 to 280 cm). None of the survived patients was parenteral nutrition-dependent. Of the 5 deaths, 2 died of recurrence of thrombosis and necrosis of the remaining bowel,1 of massive gastrointestinal bleeding. One patient abandoned treatment intra-operatively, and another with total small bowel resection abandoned treatment postoperatively.

CONCLUSIONSDamage control approach improves the survival of patients with AMI. Thrombectomy and thrombolysis are necessary for AMI management to prevent progression or further development of the thrombosis.

OBJECTIVETo study the clinical and pathologic features of ischemic intestinal disease due to mesenteric phlebitis.

METHODThe clinical and pathologic features of the mesenteric venous lesions in 3 patients of ischemic intestinal disease admitted during the period from 2003 to 2004 were studied.

RESULTSAll 3 patients had a clinical history of acute abdominal pain accompanying with a diffuse peritonitis. During operation, an infarcted intestinal segment was identified and was resected respectively in each patient. Histologic examination showed a lymphocytic infiltration and fibrinoid necrosis of the small to medium-sized veins, associated with mural thrombosis and infarction of the corresponding intestinal wall and mesentery. The mesenteric arteries were spared. Two-year follow up of one case showed no evidence of local recurrence or systemic vasculitis.

CONCLUSIONSIschemic intestinal disease due to mesenteric phlebitis is a rare entity with a pathological feature of inflammation of venous wall accompanying with the development of mural thrombosis and subsequent haemorrhagic infarction of intestine. The etiology is unknown and surgical resection of the involved intestinal segment is usually recommended.

Intestinal ischemia is divided into three categories, namely, acute mesenteric ischemia (AMI), chronic mesenteric ischemia (CMI), and colonic ischemia. AMI can result from arterial or venous thrombi, emboli, and vasoconstriction secondary to low-flow states. It is an urgent condition which can result in high mortality rate. The predominant causative factor of CMI is stenosis or occlusion of the mesenteric arterial circulation, and it is characterized by postprandial abdominal pain and weight loss. Surgery is the treatment of choice for intestinal ischemia. However, it has been recently reported that percutaneous transluminal angioplasty with stent placement and/or thrombolysis is an effective therapy in various types of mesenteric ischemia. We report six cases of mesenteric ischemia which were successfully treated by percutaneous angioplasty, and review the literature from South Korea.

Objective To investigate the role of multi-detector computed tomography (CT) in the diagnosis and classification of isolated spontaneous superior mesenteric artery dissection (ISSMAD). Methods From July 2012 to December 2016, 30 consecutive patients with ISSMAD underwent CT scan at least two times. We retrospectively summarized the clinical characteristics and CT findings of them. The stenosis ratio of true lumen was compared between the patients without bowel ischemia and ones with bowel ischemia. Results There were 5 cases of type I ISSMAD, 14 cases of type 2, 1 case of type 3, 7 cases of type 4 and 3 cases of type V. Intestinal ischemia occurred in 5 patients. The stenosis ratio of true lumen in the patients without bowel ischemia was lower than that with bowel ischemia (45.6% vs. 76.0%, t=-14.5, P=0.000). Five patients with intestinal ischemia underwent superior mesenteric artery stenting and others received conservative therapy. The abdominal pain was alleviated for all the patients after treatment. Follow-up was complete in 30 cases. Follow-up CT angiography of superior mesenteric artery showed dissection remodeling in 12 patients. Conclusion Multi-detector CT is a valuable method in diagnosis and classification of ISSMAD and monitoring the changes of dissection.

OBJECTIVE To investigate the etiology, prevention and treatment of colon ischemia after operation for abdominal aortic aneurysm (AAA). METHOD Seven of 140 cases complicated with colon ischemia who had received AAA operation were analyzed retrospectively. RESULTS Three cases underwent emergency operation. The seven cases were subjected to removal of AAA, implantation of prosthesis, and ligation of the inferior mesenteric artery. Two cases had the ligation of the bilateral internal iliac artery (IIA). Epilateral IIA was ligated in 2 cases. Bowel resection was carried out in 3 cases, 1 of which received reconstruction of the inferior mesenteric artery (IMA). Three cases received conservative therapy, but died from multiply organ failure. CONCLUSION Correct prevention and management of colon ischemia can effectively reduce the operative morbidity of AAA patients.
