INTRODUCTION

The main risk issue for acute artery dissection is that the diameter of the artery surpassing four cm (diagnosed in seventy three.7% of cases). This study was to guage the short-run results of surgical procedure in patients with acute artery dissection patients and ways. The most surgical complications are hemorrhage (42.1%), injuries of central systema nervosum (23.7%), and shock (18.4%).

More than [1] (57.9%) of patients were operated on among the primary twenty four hours when admission. within the majority of cases (73.7%), the diameter of the artery exceeded four cm. within the presence of group A artery dissection, all patients underwent surgery on internal organ bypass; its length varied from twenty to 485 min, with a mean of 214.6±102.9 min. The mean artery cross-clamp time was 114.5±62.7 min. complete circulatory arrest was required within the majority of cases (86.8%), and it lasted a pair of two ninety seven min (mean, 27.4±18.6 min). throughout internal organ bypass, vital sign was diminished to 17–28°C (mean, 18.9±1.95°C). the target of this study was to guage the short-run results of surgical procedure in patients with acute artery dissection patients and ways. A retrospective analysis of thirty eight patients with acute group A artery dissection World Health Organization were surgically treated at the Clinic of viscus, Thoracic, and tube Surgery, Hospital of city University of medication, from Jan 2004 to Dec 2007 was conducted.

During internal organ bypass, vital sign was diminished to 17–28°C (mean, 18.9±1.95°C). The length of surgery ranged from one to fourteen hours, with a mean of vi.1±2.49 hours. throughout the first surgical amount, 12 (31.6%) patients died. surgical hemorrhage was seen in sixteen (42.1%) patients, and vi of them died later. thanks to prolonged hemorrhage, 4 (10.5%) patients were left with associate degree open breastbone when surgery. Resternotomy was performed in nine patients; three of them died thanks to multiorgan injury. Throughout surgical amount, shock of assorted degrees was seen in seven (18.4%) patients. Central systema nervosum injury occurred in nine (23.7%) patients. A 50-year-old man was admitted as associate degree emergency for acute left-leg anemia. He was a smoker and had undergone aortobifemoral bypass for adipose tissue a pair of years earlier while not reimplantation of the inferior arteria (IMA). Computed axial tomography (CT) X-ray photography disclosed occlusion of the left leg of the graft furthermore as a superior arteria (SMA) and a typical hepato spleno stomachic trunk arising from a celiacomesenteric trunk [1,2]. Winning excision was performed. Unit of time later, he conferred associate degree acute abdominal pain with haemodynamic instability and elevated bottle-feed (4 times the traditional value) and transaminases (6 N). A replacement CT scan showed occlusion of this celiacomesenteric trunk, with a scarcity of sweetening of the viscus wall when distinction media injection and diffuse serosa liquid, indicating peritoneum anemia. Emerging incision confirmed these radiological findings, with associate degree anaemia liver and sphacelus of the colon, the small intestine and also the gall- bladder. Despite associate degree aggressive approach (thrombectomy of the SMA and arteria, total colectomy, enterectomy of one meter, cholecystectomy), the patient died twelve hours later [3].

It is widely agreed that two visceral arteries are sufficient for digestive functions.3 the absence of the IMA explains the cataclysmic presentation of the thrombosis of the celiacomesenteric trunk in this case. This kind of vascular variation has to be known by surgeons and radiologists because it may change the management of abdominal aneurysms and atherosclerosis, and indicate for example the re-implantation of the IMA during aortobifemoral bypass [4]. The infection of aortic root is not common pathology; however, it is a complicated disease. Esophageal echocardiography is an informative method while diagnosing aortic root abscesses. The in hospital mortality is increased by the heart failure persisting after the operation and sepsis. The long-term survival is decreased by preoperative infective endocarditis of the prosthesis and heart failure. The mortality rate of patients older than 50 years is 3-fold higher than mortality rate of younger ones in hospital mortality rate was 14.3%. The causes of death included sustained heart failure and sepsis.

The celiac trunk commonly arises at the level of twelfth thoracic vertebra and comprises the left gastric artery, the common hepatic artery and the splenic artery. The superior mesenteric artery arises 1 cm below, at the level of L1. In embryonic development, the abdominal visceral arteries arise from the primitive dorsal abdominal aorta through four roots: the left gastric artery, the hepatic artery, the splenic artery and the superior mesenteric artery. These roots are joined together by a longitudinal ventral anastomosis. Normally, a cleft forms in this anastomosis between the third and fourth roots thus isolating the celiac trunk from the superior mesenteric artery. The common celiacomesenteric trunk is a rare variation (0.5%) of the anterior branches of the abdominal aorta. It is usually asymptomatic and may be discovered incidentally during vascular explorations or during cadaver’s dissection. Rarely, it may cause symptoms including unspecific abdominal pain to real abdominal angina when associated to atherosclerosis. It was classified [5].

All these patients were in NYHA functional class IV preoperatively; one of these patients had culture positive for Staphylococcus aureus. In hospital survival was 85.7% one-year postoperative survival – 80.9%, and both fiveyear and ten-year survivals were 76.0%. The long-term survival was negatively influenced by recurrent infective endocarditis, heart failure, and age. Death occurred in 1 patient (11.1%) of the 9 patients who at the time of surgery were younger than 50 years and 4 patients (33.3%) of the 12 who were older than 50 years at the time of operation [6,7].

Three peripherals are cannulated before the operation patient’s arteries (right and left radial artery her and femoral artery) to measure BP. In addition, ponies central and peripheral intravenous fluids for infusions. The chest is opened during the procedure median sternotomy. Assessing the aortic dissection the nature of the infection, the location of its cannulation is chosen, and 4 (10.5%) patients had to cannulate their thighs artery. Two of them had to do it after the aorta delamination of the standard coronal connection during the holding operation. The third patient has this artery cannulated after diagnosing a huge ruptured ascending aneurysm of the aorta, and the fourth one during the suspension totic aortic surgery after previous Cabrioli surgery- for whom the iliac artery is prepared before the sternoturn 24 (63.1%) cannulated aorta in the area of the arch patients, but directly into the lumen of the opened aorta (eye under control) a cannula was inserted in 10 (26.3%) patients. Myocardial protection was performed in a standard way. An increased number of 5A alleles leads to high expression of MMP-3. Thus, objective of the study was to determine whether the 5A/6A polymorphism in the promoter region of MMP-3 gene is associated with the development of dilatative pathology of ascending thoracic aorta. We studied 76 patients (age ranged from 31 to 81 years; median age, 64 years) who underwent aortic reconstruction surgery due to dilatative pathology of ascending thoracic aorta and a random sample of the population (n=604) aged 25–64 years, all from Lithuania [8-10]. DNA was analyzed by using real-time polymerase chain reaction to genotype polymorphism 5A/6A at a position – 1171 of the MMP3 gene promoter. The prevalence of MMP- 3 genotypes was similar in the group of dilatative pathology of ascending thoracic aorta and random sample of population. The frequency of 5A allele did not differ significantly between both groups and was 0.506 and 0.514, respectively. Male carriers of 5A/5A genotype were significantly younger compared with those with the 6A/6A genotype [11-13]. In conclusion, the frequency of MMP-3 promoter 5A/6A genotypes did not differ between the group of patients with dilative pathology of ascending thoracic aorta and the random sample of population, but the males with dilative pathology of ascending thoracic aorta and 5A/5A genotype required aortic reconstruction surgery at the younger age than the males carrying 6A/ 6A genotype in the MMP-3 promoter region. DNA quality and concentration were estimated by spectrophotometrical analysis and by ethidium bromide stained agarose gel under ultraviolet light. The latter method was used to evaluate DNA degradation level in the samples from paraffin-embedded aortic tissue [14,15].
