Abstract
Mesenteric ischemia is a medical condition in which injury to the small intestine occurs due to not enough blood supply (Luchette and Yelon 2017). It can come on suddenly, known as acute mesenteric ischemia, or gradually, known as chronic mesenteric ischemia. The acute form of the disease often presents with sudden severe abdominal pain and is associated with a high risk of death (Bobadilla 2013). The chronic form typically presents more gradually with abdominal pain after eating, unintentional weight loss, vomiting, and fear of eating (Luchette and Yelon 2017). Risk factors for acute mesenteric ischemia include atrial fibrillation, heart failure, chronic kidney failure, being prone to forming blood clots, and previous myocardial infarction (Luchette and Yelon 2017). There are four mechanisms by which poor blood flow occurs: a blood clot from elsewhere getting lodged in an artery, a new blood clot forming in an artery, a blood clot forming in the superior mesenteric vein, and insufficient blood flow due to low blood pressure or spasms of arteries (Luchette and Yelon 2017). Aim of the work : The aim of this study was to assess incidence of mesenteric vascular ischemia among patients in mansoura emergency hospital. Result : Our study included 148 patients from 1815 patients presented with acute abdomen at Mansoura university emergency hospital between July 2019 and July 2020. Regarding the demographic characteristics of the included 148 cases diagnosed with AMI the mean age was 55.44±4.53 years with the range of 48-61.0 years. The study included 98 males (66%) and 50 females (34%). Laboratory investigation must do pre-operation in our study blood data of hemoglobin are (13.18), WBC are (12.34), ALT is (34), AST are (42), INR are (1.1), PT are (92.89), total bilirubin is (0.56), direct bilirubin is (0.18), Platelet are (101), are (3.64) and Creatinine are (0.83). Although, The D-dimer in this study cases were ≤ 693 ng/mL (46 Patients), were > 693 ng/mL (102 Patients). The most frequent medical co-morbidities faced in the study cases were Hypertension (51%). Hyperlipidemia was present in (46%), diabetes mellitus was present in (66%), while cardiac co-morbidity (as atrial fibrillation (AF), myocardial infarction (MI)) was positive in (38%). Risk factors of Acute mesenteric ischemia in the study cases Splenectomy (41%). Cirrhosis was present in (45%), Atrial fibrillation (AF) was present in (36%), while Peripheral arterial disease was positive in (45%). When it comes to Medication in the study cases were Warfarin was present in (46.6%), Acetylic salicylic acid was present in (27.7%), while Clopidogrel was present in (19%), while Statin was present in (6.7 %). In case of Diagnostic modalities in this study cases were CT was present in (47%), CT angiography was present in (49%), while DSA was present in (15%), while Laparotomy was present in (25%). In case of Length of resected part in this study cases were 5-40 cm was present in (20 %), 41-75 cm was present in (66 %), while 76-110 cm was present in (20 Patients). In case of Distance from duodenojejunal (DJ) in the study cases were 200-235 cm (30 %). 236-270 cm was present in (34 %), 271-295 cm was present in (36 %)
