2/149. Nonocclusive small bowel infarction in familial dysautonomia syndrome.The authors report a case of a 14-year-old boy with familial dysautonomia (FD) in whom a small-bowel infarction developed during a dysautonomic crisis. Atypical features of the presentation included hypotension with prolonged fever and abdominal distension. The authors postulate that the bowel infarction was caused by prolonged hypoperfusion. It is recognized that the small bowel in normal subjects can adapt to periods of ischemia without irreversible injury. The authors speculate that the known abnormal systemic cardiovascular regulation in patients with FD may adversely affect splanchnic blood flow, which led to the catastrophic consequences in this case. This report draws attention to the risk of significant ischemic complications during a dysautonomic crisis, especially in the face of atypical features, and emphasizes the challenging cardiovascular management of such patients.- - - - - - - - - - ranking = 1.75keywords = bowel (Clic here for more details about this article) |
3/149. Pathologic findings in a steroid-responsive optic nerve infarct in giant-cell arteritis.OBJECTIVE: To investigate the pathophysiologic mechanism of optic nerve infarction in giant-cell arteritis (GCA). BACKGROUND: Previous pathologic reports of optic nerve infarction in GCA involved patients who were blind at the time of death. The optic nerve infarcts were primarily retrolaminar in localization. Simultaneous short ciliary and ophthalmic artery vasculitis was found in all patients. methods: Clinical neurologic and ophthalmologic examination, temporal artery biopsy, and neuroimaging tests were performed in a patient with an anterior ischemic optic neuropathy secondary to GCA. Pathologic examination of the viscera, eye, and brain were performed at autopsy 1 month later. RESULTS: A prelaminar/retrolaminar infarct was found in this patient. Subsiding vasculitis was limited to the short ciliary arteries, sparing the central retinal, pial, and ophthalmic arteries. CONCLUSIONS: The authors believe that the visual improvement observed in this patient was the result of preserved, anterior optic nerve collateral circulation, as well as the neuroprotective and anti-inflammatory effect of the corticosteroids.- - - - - - - - - - ranking = 0.0015895870336529keywords = short (Clic here for more details about this article) |
4/149. Mesenteric infarction due to combined protein c deficiency and prothrombin 20210 defects.The prothrombin gene mutation, 20210A, a guanine to adenine substitution at nucleotide position 20210, has recently been described as an additional risk factor for venous thromboembolic disease. We describe the case of a patient with combined heterozygous prothrombin 20210A mutation and type 1 protein c deficiency who presented with massive mesenteric venous infarction of his small bowel and survived following the use of protein C concentrate and extensive small bowel resection.- - - - - - - - - - ranking = 0.5keywords = bowel (Clic here for more details about this article) |
5/149. uterine perforation resulting in bowel infarction: sharp traumatic bowel and mesenteric injury at the time of pregnancy termination.BACKGROUND: By law, elective terminations of pregnancy are not performed in U.S. military institutions. However, in the civilian sector, more than a million abortions are performed each year, some of which are on military beneficiaries. Although complications are relatively rare, patients not uncommonly present for follow-up care to their military installation. We report the case of a patient who presented after a second-trimester elective abortion and was found to have suffered uterine perforation with mesenteric and bowel injury that required bowel resection. CASE: An 18-year-old gravida 1 para 0 female presented from an outlying facility 1 week after elective termination at 18 weeks of gestation with complaints of severe abdominal pain, nausea, and vomiting. Exploratory laparotomy for presumed bowel obstruction revealed uterine perforation and bowel devitalization and necrosis, which required small bowel resection. Fetal bones were discovered within the surgical specimen. CONCLUSION: Morbid, even potentially fatal, complications can occur as a result of pregnancy termination. With second-trimester procedures, perforation can result in injury to abdominal viscera from the perforating instruments or even from sharp fetal bony structures. Military gynecologic surgeons, who are not in abortion practice, must nevertheless be cognizant of the potential for perforation leading to serious visceral injury.- - - - - - - - - - ranking = 3.25keywords = bowel (Clic here for more details about this article) |
6/149. Mesenteric venous thrombosis associated with oral contraceptives: a case report.Small-bowel infarction resulting from mesenteric venous thrombosis is a rare but life-threatening complication to which young women taking oral contraceptives are liable. The patient characteristically presents with an "acute abdomen" after a variable prodromal period of vague abdominal pain. The correct diagnosis can be made from the macroscopic appearance at laparotomy, provided the surgeon is alert to the condition. An accurate diagnosis is important, as anticoagulation measures must be instituted early to counter the commonly associated thromboembolic phenomena.- - - - - - - - - - ranking = 0.25keywords = bowel (Clic here for more details about this article) |
7/149. Acute mesenteric infarction caused by small vessel disease.A case of acute mesenteric infarction caused by small vessel disease is reported. The patient recovered after 2 operations by which extensive bowel-resections were performed. The resected bowel showed intimal hyperplasia and atherosclerosis of the small mesenteric arteries. Since also thrombocytosis and increased platelet aggregation was demonstrated the main cause of thrombosis however is supposed to be hypercoagulability.- - - - - - - - - - ranking = 0.5keywords = bowel (Clic here for more details about this article) |
8/149. Spontaneous superior mesenteric vein thrombosis (SMVT) in primary protein s deficiency. A case report and review of the literature.Superior mesenteric vein thrombosis (SMVT) is an uncommon but important clinical entity that can induce ischemia or infarction of the small and large bowel. It is rare and accounts for 5-15% of mesenteric vascular occlusions. Bowel infarction due to SMVT can present as an acute abdominal disease, requiring urgent laparotomy with resection of the intestinal segment affected. However, the clinical diagnosis of this event remains difficult and invariably requires specific imaging investigations in order to be able to treat the condition as soon as possible. SMVT without bowel infarction can present as persistent, non-specific abdominal pain and nausea with minimal clinical signs, affecting young individuals without any known predisposing disorder, where laparotomy is not an urgent indication. We report a case of a young adult man with SMVT due to a hypercoagulable state (protein s deficiency), in whom an early diagnosis and appropriate anticoagulant treatment prevented any further extension of the thrombotic process and limited the hemorrhagic infarction of the ileum, which simply required a segmental resection.- - - - - - - - - - ranking = 0.5keywords = bowel (Clic here for more details about this article) |
9/149. Isolated mesenteric injury due to blunt abdominal trauma.Isolated injuries of the small bowel mesentery or mesocolon with subsequent bowel infarction due to blunt abdominal trauma are rare. Two cases are described: 1 involving the mesentery to the terminal ileum and 1 involving the transverse mesocolon and middle colic artery, both with bowel infarction. The modes of clinical presentation and management of patients with injuries to the mesentery, mesocolon and mesenteric vessels following blunt trauma are described.- - - - - - - - - - ranking = 0.75keywords = bowel (Clic here for more details about this article) |
10/149. A catastrophic complication of systemic lupus erythematosus: massive mesenteric infarction.The AA reports a case of a 64-year-old female patient affected for 3 years by systemic lupus erythematosus who developed a massive perforating mesenteric infarction. An immediate surgical treatment with resection of the small bowel and right colon followed by a side-to-side primary anastomosis between the remaining jejunum and transverse colon were performed. The patient died 15 days after surgery due to recurrence of a mesenteric and pulmonary thromboembolia.- - - - - - - - - - ranking = 0.25keywords = bowel (Clic here for more details about this article) |
