1/68. 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.- - - - - - - - - - ranking = 1keywords = spleen (Clic here for more details about this article) |
2/68. 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.- - - - - - - - - - ranking = 1keywords = spleen (Clic here for more details about this article) |
3/68. 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.- - - - - - - - - - ranking = 2keywords = spleen (Clic here for more details about this article) |
4/68. 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.- - - - - - - - - - ranking = 1keywords = spleen (Clic here for more details about this article) |
5/68. 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.- - - - - - - - - - ranking = 4keywords = spleen (Clic here for more details about this article) |
6/68. 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.- - - - - - - - - - ranking = 1.4508931327649keywords = spleen, splenomegaly (Clic here for more details about this article) |
7/68. Non hypoxia-related splenic infarct in a patient with sickle cell trait and infectious mononucleosis.splenic infarction in patients with sickle cell trait is usually related to hypoxic conditions, while non-hypoxia-related infarcts are extremely rare. We report on a case of a 17-year-old male patient, living at sea level, who developed a severe left upper quadrant abdominal pain during the course of a febrile episode. On physical examination he had a mildly palpable but extremely painful spleen. A spleen scan revealed 2 areas of impaired radionucleide distribution. Hepatic enzymes were moderately increased and the IgM anti-EBV antibodies positive. Hemoglobin electrophoresis revealed the presence of 42% of hemoglobin S. A probable diagnosis of splenic infarction was established in a patient with sickle cell trait, during the course of infectious mononucleosis. The patient was treated symptomatically. The conditions of splenic congestion induced by the EBV infection and the high-grade fever may have contributed to splenic sequestration and subsequent infarcts.- - - - - - - - - - ranking = 2keywords = spleen (Clic here for more details about this article) |
8/68. A rare cause of acute abdomen: splenic infarction.splenic infarction is a rare disorder. We have treated 4 patients during the last year. abdominal pain in the left upper quadrant was the common complaint. Other complaints were fever, nausea and vomiting. Computed tomography showed infarcted areas in the spleen in all of the patients. splenectomy was applied to three of the patients with recurring symptoms. The other patient had the first episode treated medically. pulmonary embolism in one and surgical wound infection occurred in another patient during postoperative follow-up for nine (range: 4-14) months.- - - - - - - - - - ranking = 1keywords = spleen (Clic here for more details about this article) |
9/68. intestinal obstruction caused by infarcted splenic hemangioma with renal vein thrombosis in a newborn: a case report.The spleen in newborns, infants, and children is rarely involved in a variety of pathological processes. These processes may involve an isolated splenic disease or may be a part of a systemic illness. Renal vein thrombosis in infants of diabetic mothers has been reported. We report a case of a newborn with intestinal obstruction caused by an infarcted splenic hemangioma and renal vein thrombosis. To the best of our knowledge, this is the youngest case with both above-mentioned diagnoses and causes of intestinal obstruction in the English medical literature.- - - - - - - - - - ranking = 1keywords = spleen (Clic here for more details about this article) |
10/68. Splenic accumulation of 99mTc-diphosphonate in a patient with sickle cell disease: case report.Splenic accumulation of 99mTc-diphosphonate is shown in the bone scan of a patient with sickle cell disease. This uptake is assumed to result from splenic infarction and subsequent calcification. The conventional liver-spleen scan with 99mTc-sulfur colloid shows no splenic activity, and a radiograph shows calcification in the left upper quadrant of the abdomen in the expected anatomic location of the spleen.- - - - - - - - - - ranking = 2keywords = spleen (Clic here for more details about this article) |
