1/94. Splenic syndrome in sickle cell trait: four case presentations and a review of the literature.

    Four cases of splenic infarction/sequestration in sickle cell trait (SCT) patients are presented. All four patients were undergoing moderate exercise at elevations ranging from 5,500 to 12,000 feet. The patients include two African-American males, a Hispanic male, and a white female. All four presented with the acute onset of mid epigastric then left upper-quadrant pain, nausea, vomiting, and respiratory splinting. A review of the literature indicates that splenic infarction with SCT is not uncommon; however, not surprisingly, it is often initially misdiagnosed. This is the first report in the literature of a female with SCT incurring a splenic syndrome with exposure to terrestrial altitude. Although SCT is not a contraindication for moderate- or high-altitude activities, military physicians need to consider the diagnosis of splenic infarction early in any patient regardless of race or sex who presents with left upper-quadrant pain at altitudes above 5,000 feet. Prompt evacuation to sea level may hasten recovery and spare further splenic trauma. Although SCT should be considered a relatively benign entity, the literature also suggests a higher than average risk of sudden death in military recruits with SCT from exertional heat illness and rhabdomyolysis.

2/94. splenic infarction complicating ligation of a gastroduodenal artery aneurysm.

    BACKGROUND: Aneurysms of visceral arteries are rare, but may lead to dramatic situations of intraabdominal or retroperitoneal hemorrhage in case of rupture. CASE REPORT: We report the case of a 72-year-old patient who developed a hemorrhagic shock following a total hip replacement due to the rupture of an aneurysm of the gastroduodenal artery. angiography also demonstrated a high-grade stenosis of the celiac trunk. The ruptured aneurysm was ligated as a live-saving procedure, but due to the stenosis in the celiac trunk the patient developed a splenic infarction followed by partial tissue liquefication. This was treated conservatively and after 3 months, the computed tomography showed an atrophic residual spleen. SUMMARY: Diagnostic and therapeutic approaches to visceral vascular aneurysms are discussed including the potential complications of splenic infarction.

3/94. Hypertrophic cardiomyopathy with mid-ventricular obstruction and splenic infarction associated with paroxysmal atrial fibrillation: a case report.

    A 54-year-old woman had been treated for hypertrophic cardiomyopathy and paroxysmal atrial fibrillation since 1992. She was admitted with paroxysmal atrial fibrillation which was resolved by medical treatment. However, on the next day, left lateral chest pain appeared. Computed tomography disclosed a low density area in the spleen. She received anticoagulant therapy under a diagnosis of splenic infarction, and the pain disappeared. echocardiography showed hypertrophic cardiomyopathy with mid-ventricular obstruction. She was treated with cibenzoline to prevent paroxysmal atrial fibrillation attack and attenuate the hemodynamic load. After treatment, the pressure gradient decreased from 41 to 7 mmHg. This patient with hypertrophic cardiomyopathy suffered a rare isolated splenic infarction associated with paroxysmal atrial fibrillation.

4/94. Spontaneous splenic infarction secondary to diabetes-induced microvascular disease.

    splenic infarction is a clinical entity seldom encountered. The most frequent causes of splenic infarction include thromboembolic phenomena, hematologic malignant neoplasms, and vasculitides. We describe a patient who sustained splenic infarction secondary to diabetes-induced, small-vessel atherosclerotic disease.

5/94. splenic infarction in pregnancy.

    We present a case of splenic infarction in pregnancy, secondary to acute bacterial endocarditis. Left upper quadrant pain in pregnancy can be due to a variety of causes and in the septic or unwell patient, splenic infarct should be considered in the differential diagnosis. The diagnosis of splenic infarct should be considered especially in those at increased risk of bacterial endocarditis. Acute bacterial endocarditis can occur even in patients without any risk factors. Bacterial endocarditis is rare in pregnancy and splenic infarction is even rarer. However when it occurs, rapid diagnosis and management are necessary to minimize embolic phenomena. With the increasing use of intravenous drugs and with increasing numbers of Pacific Islanders in our pregnant population, it is important to be alert to the risk of bacterial endocarditis and to avoid serious sequelae. Patient education to the importance of medical follow-up in order to prevent such a life-threatening condition, and to avoid more complicated acute treatment, is imperative.

6/94. Massive splenic infarction in cirrhosis: report of a case with spontaneous disappearance of hypersplenism.

    A cirrhotic patient with massive splenic infarction is described. Celiac angiography showed normally opacified splenic artery and vein and a markedly enlarged spleen with large avascular zones. splenic infarction was associated with the spontaneous disappearance of a syndrome of hypersplenism. The spleen was surgically removed. Histological examination showed multiple thromboses of the small arterial and venous vessels. The cause of this infarct remained unclear.

7/94. dermatomyositis with splenic and renal infarctions during corticosteroid therapy.

    A 60-year-old woman was admitted to our hospital with complaints of muscle weakness and erythema on her extremities. Gottron's sign, heliotrope rash, elevation of serum myogenic enzymes, electromyography and magnetic resonance imaging findings established a diagnosis of dermatomyositis (DM). She was treated with 60 mg of daily prednisolone. One week later, she suddenly developed splenic and renal infarctions, which were considered to have resulted from vasculopathy associated with DM. cyclophosphamide and anticoagulants along with increasing the dosage of corticosteroid were effective. This is the first report describing splenic and renal infarctions in a patient with adult-onset DM.

8/94. Isolated dissection of the celiac artery--a case report.

    Isolated arterial dissection, which occurs with the absence of aortic dissection, has been reported in carotid and renal arteries but rarely in visceral arteries. A case of isolated celiac artery dissection is reported here. A healthy 58-year-old man experienced sudden upper abdominal pain, which continued for several days. A body computed tomogram (CT) showed a multiple low-density wedge-shaped area in the spleen, which was diagnosed as splenic infarction, and an aneurysm with thrombus in the celiac artery. A selective angiogram showed dilatation of the celiac artery with wall irregularity, and proximal occlusion of the hepatic artery. The distal hepatic artery was fed by collateral arteries from the superior mesenteric artery. splenic infarction was probably due to the embolism from the thrombus in the dissected celiac artery. The absence of other vascular lesions and causes or risks for the arterial dissection would suggest the occurrence of spontaneous dissection. The dissection of visceral arteries should be considered in diagnosing acute abdominal pain.

9/94. Noninfectious gas accumulation in an infarcted spleen.

    BACKGROUND: Intentional selective occlusion of the arterial blood supply to tumors of abdominal organs is a well established therapeutic procedure. Several reports described gas accumulation at the infarcted sites. These gas collections are usually nonsuppurative; however, the differential diagnosis should include abscess formation. CASE REPORT: We present a 59-year-old patient in whom the splenic artery was accidentally ligated during gastrectomy surgery, with resultant splenic infarction. Gas accumulation was diagnosed by sonography and CT studies. To the best of our knowledge this is the first report ever published in the English medical literature describing nonsuppurative gas formation within an abdominal organ, caused by accidental ligation of its main arterial supply during surgery. SUMMARY: Possible theories regarding this noninfectious gas accumulation are discussed and the differential diagnosis between abscess formation and noninfectious gas accumulation is emphasized. Establishing the correct diagnosis is of big clinical importance as the treatment of choice is completely different in each one of these entities although the imaging features, in ultrasound as well as in CT, are somewhat similar.

10/94. Thermophilic multidrug-resistant campylobacter fetus infection with hypersplenism and histiocytic phagocytosis in a patient with acquired immunodeficiency syndrome.

    We present a case report of a patient who had acquired immunodeficiency syndrome (AIDS) and campylobacter fetus infection with a number of unusual clinical and microbiological features. The patient had prominent gastrointestinal symptoms, splenic infarction, splenomegaly with hypersplenism, and hemophagocytic histiocytosis in the spleen and lymph nodes; the organism displayed growth on Campy-selective blood agar, thermotolerance, and resistance to quinolones, piperacillin/tazobactam, ceftazidime, and erythromycin.
