1/18. Acute appendicitis in a young adult with midgut malrotation: a case report.Midgut malrotation is defined as a developmental anomaly that may cause atypical clinical symptoms in relatively common intestinal disorders due to altered anatomy. A 27-year-old woman presented with acute left-sided abdominal pain. Underlying type Ia malrotation prevented the correct clinical diagnosis of perforated, ulcerated appendicitis. Cross-sectional imaging demonstrated all the typical signs of this type of malrotation, i.e., right-sided duodenojejunal junction, left positioned cecum and ascending colon, inverted position of the superior mesenteric vessels, and hypoplasia of the uncinate process of pancreas, and surgical treatment was initiated.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/18. Small bowel perforation as a complication of microsurgical lumbar diskectomy. A case report and brief review of the literature.Ventral perforation is a rare complication of lumbar diskectomy. Injury to retroperitoneal vessels is the most common serious complication to such perforation. Ventral perforation with damage to the bowel is rarely reported. The authors present the first case report of injury to the small bowel during a microsurgical lumbar diskectomy. The case illustrates the importance of awareness of bowel injury as a possible complication of diskectomy. Possible pre- and postoperative considerations are also discussed. A brief review of the literature on bowel injuries after this common surgical procedure is also given.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/18. Primary appendiceal adenocarcinoma of colonic type with perforating peritonitis.Primary adenocarcinoma of the appendix is rare, especially the colonic type. We report a case of appendiceal adenocarcinoma of colonic type associated with perforating peritonitis after aorto-femoral artery bypass surgery. A 79-year-old woman presented with fever and pain in the right lower abdomen. She had undergone aorto-femoral artery bypass surgery due to arteriosclerosis obliterans 6 months earlier. Abdominal ultrasonography and computed tomography showed a suspected pool of fluid surrounding the artificial vessel and a mass lesion in the upper end of the fluid collection. These findings suggested localized peritonitis due to appendiceal perforation. Emergency laparotomy showed a pool of pus around the artificial vessel and inflamed appendix, which adhered to the surrounding tissue. The mass was excised in combination with an ileocaecal resection, followed by an ileocolic anastomosis. The histological diagnosis was moderately differentiated adenocarcinoma of the appendix, colonic type. The tumour had infiltrated and obstructed the lumen of the orifice of the appendix, which may have caused perforation of the appendix. She was examined at regular periodic follow-ups and no evidence of recurrence or metastasis was noted in the 12-month postoperative period. These findings indicate that, in cases of acute appendicitis, especially with perforation, the possibility of appendiceal adenocarcinoma should be considered.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
4/18. The Ehlers-Danlos specter revisited.Ehlers-Danlos type IV is a major concern to vascular surgeons because it is often associated with spontaneous hemorrhage from arteries containing decreased type III collagen. Five members of a family with Ehlers-Danlos type IV and a review of another family of five with Ehlers-Danlos type IV are reported. Evaluation of the recent family included clinical evaluation as well as assay of collagen production. The age range of the three involved females and two males was 7 to 52 years. The father of the affected family had a spontaneous colon perforation at age 39. His son, at age 27, had a spontaneous rupture of the iliac artery. Revascularization was accomplished with difficulty. His daughter had a large cerebral bleed. Two granddaughters, ages 7, have not had any bleeding or aneurysmal events. The amount of type III collagen was only 10% of normal in the patient with the iliac artery rupture. The three females all exhibited similarly low levels of type III collagen. The father's type III collagen level was not sufficiently low to confirm Ehlers-Danlos type IV, although he had a spontaneous colon perforation. In the other Ehlers-Danlos type IV family of five, the three surviving members had type III collagen levels as low as 5% of normal. Two family members died after spontaneous iliac rupture at ages 24 and 33. Both families exhibited an autosomal dominant inheritance pattern. Ehlers-Danlos type IV remains a challenging problem for vascular surgeons. It is transmitted as an autosomal dominant inheritance with a high degree of penetrance. Spontaneous arterial and intestinal perforations should alert the clinician to the possibility of Ehlers-Danlos type IV. patients should be evaluated noninvasively. Arterial repairs may not be successful in these patients because the vessels are extremely friable. Assays of collagen production are advisable in establishing the diagnosis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/18. Blunt injury to the external iliac artery: a case report.Blunt vascular trauma is rare as compared with penetrating vascular trauma. The incidence of iliac artery injury has been reported as low as 0.4 per cent of total arterial trauma. iliac artery injury in blunt trauma is rare because of its anatomic location and protection by the pelvis. This article presents a case of external iliac artery injury secondary to blunt trauma. A deceleration-type mechanism is suggested that results in the production of an intimal flap and later vessel thrombosis. We discuss the clinical details of presentation and angiographic diagnosis as well as treatment options.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/18. Jejunal perforation associated with cytomegalovirus infection in a patient with adult T-cell leukemia-lymphoma.A patient with adult T-cell leukemia-lymphoma suffered a jejunal perforation, which we believe was directly attributable to cytomegalovirus (CMV) infection. In the areas of ulceration and perforation in the small bowel, blood vessels penetrating the muscularis propria showed extensive lining of cytomegalic endothelial cells with CMV inclusions, accompanied by occasional disruption of the walls, partial occlusion of the lumina, fibrin thrombi, and hemorrhage. The CMV-induced vascular damage seemed to be closely related to the occurrence of ulcers and perforation. The recognition of CMV as a cause of lethal gastrointestinal lesions in immunocompromised hosts has become more important with the advent of anti-CMV therapy.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/18. churg-strauss syndrome manifesting as perforation of the small intestine: report of a case.We report a case of churg-strauss syndrome (CSS) causing perforation of the small intestine. A 51-year-old woman was admitted with an asthma attack and paralysis of both legs. Intravenous predonisolone (40 mg) was given to relieve her asthma. Laboratory data on admission showed leukocytosis with hypereosinophilia and a high level of serum IgE. Neurological examination also revealed mononeurutis multiplex. Based on these findings, we diagnosed CSS, and oral corticosteroids were continued. On the 20th day after admission, she suffered sudden abdominal pain. Abdominal X-ray showed free air in the abdomen, suggesting perforation of the gastrointestinal tract. Emergency laparotomy revealed generalized peritonitis caused by a perforated ulcer of the ileum. The resected specimens contained a perforation and multiple nonperforated ulcers with an irregular shape on the mucosal surface. Histopathological examinations revealed angiitis of the small vessels surrounded by eosinophilic infiltration and granuloma, consistent with CSS. Considering the high risk of perforation of the gastrointestinal tract, including the small intestine, during corticosteroid treatment in patients with CSS, any abdominal pain or discomfort must be investigated carefully.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/18. Perforation and tumor formation of the intestine in primary amyloidosis.We report a case of primary amyloidosis with repeated bowel perforations. This patient also had localized amyloid deposition creating a tumorous region mimicking malignancy in the rectum. Perforation of the intestine is common in systemic amyloidosis. The ischemic change due to amyloid infiltration into the vessel wall may lead to perforation of the affected bowel. Amyloid tumors occur more often in localized amyloid than in systemic amyloidosis. Macroscopically, it is difficult to distinguish amyloid tumor of the intestine from neoplasia.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/18. schistosomiasis associated with rupture of the appendix in pregnancy.Acute appendicitis is among the most common indications for exploratory laparotomy during pregnancy. Although usually pyogenic in origin, parasitic infections account for a small percentage of cases. We report here the association of pregnancy and appendicitis caused by schistosoma japonicum. schistosomiasis is a very common complication of pregnancy, with 250,000,000 persons infected worldwide, including 20% of pregnant women living in hyperendemic areas. Schistosome egg masses can lodge throughout the body and cause acute inflammation of the appendix, fallopian tube, liver, and spleen. Congestion of pelvic vessels during pregnancy facilitates passage of eggs into the villi and intervillous spaces, causing an inflammatory reaction. Fetal anoxia and subsequent death has been attributed to heavy infestation of the placenta. Tourism, far-ranging military actions, and immigration make this disease a potential challenge for practitioners everywhere.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/18. cytomegalovirus vasculitis and colon perforation in a patient with the acquired immunodeficiency syndrome.We describe a patient with the acquired immunodeficiency syndrome who suffered a colon perforation which we believe was directly attributable to disseminated cytomegalovirus (CMV) infection. Thrombosed vessels within the submucosa and muscle wall contained evidence of CMV vasculitis, while adjacent vessels without viral inclusions were fully patent. This report supports other evidence that CMV may act as a primary etiologic agent of gastrointestinal disease, particularly in the immunocompromised host. The increased recognition of CMV as a cause of significant morbidity in certain gastrointestinal lesions becomes especially important with the advent of newer antiviral therapy specifically directed against CMV infection.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
