1/186. Systemic infection with Alaria americana (trematoda).Alaria americana is a trematode, the adult of which is found in mammalian carnivores. The first case of disseminated human infection by the mesocercarial stage of this worm occurred in a 24-year-old man. The infection possibly was acquired by the eating of inadequately cooked frogs, which are intermediate hosts of the worm. The diagnosis was made during life by lung biopsy and confirmed at autopsy. The mesocercariae were present in the stomach wall, lymph nodes, liver, myocardium, pancreas and surrounding adipose tissue, spleen, kidney, lungs, brain and spinal cord. There was no host reaction to the parasites. Granulomas were present in the stomach wall, lymph nodes and liver, but the worms were not identified in them. hypersensitivity vasculitis and a bleeding diathesis due to disseminated intravascular coagulation and a circulating anticoagulant caused his death 8 days after the onset of his illness.- - - - - - - - - - ranking = 1keywords = spleen (Clic here for more details about this article) |
2/186. Detection of retroperitoneal hemorrhage by transesophageal echocardiography during cardiac surgery.PURPOSE: To present a case of massive retroperitoneal hemorrhage during cardiopulmonary bypass (CPB) which was detected using transesophageal echocardiography (TEE). CLINICAL FEATURE: A 50-yr-old man suffering from severe mitral regurgitation (MR) was admitted for mitral valvuloplasty. After the beginning of CPB, the volume in the reservoir was noticed to be gradually decreasing. Although venous cannulation had been properly performed, TEE showed an echo free space around the liver, the spleen and in front of the abdominal aorta showed intraabdominal hemorrhage. After cardiac surgery, emergency laparotomy revealed about 5,000 ml of blood in the retroperitoneal space probably as a result of femoral artery cannulation prior to CPB. hemostasis was achieved, and the patient made complete cardiac and neurological recovery. Retrospective review of the TEE imaging revealed that the kidneys were surrounded by blood bilaterally confirming the diagnosis of retroperitoneal hemorrhage. CONCLUSION: Retroperitoneal hemorrhage during CPB is rare, but may be lethal. Transesophageal echocardiography is a useful monitor not only to evaluate cardiac performance, but also to detect unexpected intraabdominal bleeding during cardiac surgery.- - - - - - - - - - ranking = 1keywords = spleen (Clic here for more details about this article) |
3/186. Acute hemorrhage into the peritoneal cavity--a complication of chronic pancreatitis with pseudocyst: a case report from clinical practice.Acute hemorrhage due to a pseudocyst of the pancreas is a dangerous complication of chronic pancreatitis (CP). Without operative treatment, mortality is as high as 90%. Immediate recognition of this complication as well as urgent operative treatment allowing the survival of 70% of patients is imperative. Described is the case of a patient with CP and pseudocyst in which hyperamylasemia and unclarified anemia developed following sudden abdominal pain. The suspicion of hemorrhage into the peritoneal cavity was confirmed by selective visceral angiography showing hemorrhage from the splenic artery in the region of the hilus of the spleen. Operative treatment was successful. During the procedure, a ligature was applied to the hemorrhaging splenic artery and a splenectomy was carried out with 2500 ml of bloody contents being removed from the abdominal cavity. Acute hemorrhage into the peritoneal cavity as a complication of chronic pancreatitis with pseudocyst (CPP) requires immediate identification, confirmation by visceral angiography, and urgent operative treatment.- - - - - - - - - - ranking = 1keywords = spleen (Clic here for more details about this article) |
4/186. Occult splenic rupture: a case report.We present a case of an atraumatic, occult rupture of the spleen. It is only in a distinct minority of cases, that the splenic capsule remains intact, thereby preventing intraperitoneal bleeding. Nevertheless, this condition can be accompanied by a severe loss of blood. A nonoperative management can be considered. Reviewing the literature on splenic rupture, the lack of uniformity in nomenclature is striking. The etiological and morphological classifications are reviewed.- - - - - - - - - - ranking = 1keywords = spleen (Clic here for more details about this article) |
5/186. Functional, life-threatening disorders and splenectomy following liver transplantation.splenectomy (SPL) in cirrhotic patients undergoing liver transplantation (LTx) may resolve specific problems related to the procedure itself, in case of functional and life-threatening clinical situations often occurring as a result of liver cirrhosis and portal hypertension. METHOD: A single-center experience of ten splenectomies in a series of 180 consecutive adult liver transplant patients over a period of 6 yr is reported. The mean patient age was 46.8 /- 9.5 yr (range 25 57 yr). Indications for SPL were post-operative massive ascitic fluid loss (n = 3), severe thrombocytopenia (n = 3), acute intra-abdominal hemorrhage (n = 2), infarction of the spleen (n = 1), and multiple splenic artery aneurysms (n = 1). RESULTS: Extreme ascites production due to functional graft congestion disappeared post-SPL, with an improvement of the hepatic and renal functions. SPL was also effective in cases of thrombocytopenia persistence post-LTx, leading to an increase in the platelet count after about 1 wk. Bleeding episodes related to left-sided portal hypertension or trauma were also resolved. The rejection rate during hospitalization was 0%, and no other episodes were recorded in the course of the long-term follow-up. However, sepsis with a fatal outcome occurred in 4 patients, i.e. between 2 and 3 wk post-SPL in three cases and 1 yr after the procedure as a result of pneumococcal infection in the last case. Fatal traumatic cranial injury occurred 3 yr post-LTx in another case. Five patients (50%) are still alive and asymptomatic after a median follow-up period of 36 months. CONCLUSION: The lowering of the portal flow appears to resolve unexplained post-operative ascitic fluid loss as a result of functional graft congestion following LTx. However, because of the enhanced risk of SPL-related sepsis, a partial splenic embolization (PSE) or a spleno-renal shunt could be used as an alternative procedure because it allows us to preserve the immunological function of the spleen. SPL is indicated in case of post-transplant bleeding due to left-sided portal hypertension and trauma, spleen infarction, and to enable prevention of hemorrhage in liver transplant patients with multiple splenic artery aneurysms. Severe and persistent thrombocytopenia could be treated with PSE. Because the occurrence of fatal sepsis post-SPL is a major complication in LTx, functional disorders, such as ascites and thrombocytopenia, should be treated with a more conservative approach.- - - - - - - - - - ranking = 3keywords = spleen (Clic here for more details about this article) |
6/186. Spontaneous rupture of a nonparasitic liver cyst complicated by intracystic hemorrhage.a case of spontaneous rupture of simple liver cyst complicated by intracystic hemorrhage is described. This rare condition was detected in a 61-year-old man who underwent left trisegmentectomy of liver under a suspected diagnosis of cystadenocarcinoma because of elevated serum levels of carbohydrate antigen (CA) 19-9 and DUPAN 2, and the presence of an intracystic structure. The resected specimen showed a benign liver cyst with intracystic hematoma and high levels of CA19-9 and DUPAN 2 in the cystic fluid. It is suggested that cyst rupture may increase serum levels of tumor markers whose levels are high in the cystic fluid, and that repeated observations of an intracystic structure may be the most reliable method to distinguish intracystic hemorrhage from cystic neoplasm.- - - - - - - - - - ranking = 0.074131886746594keywords = neoplasm (Clic here for more details about this article) |
7/186. A case of intraabdominal bleeding following pancreatoduodenectomy successfully treated by transcatheter arterial embolization.A 58-year-old male underwent pancreatoduodenectomy based on a diagnosis of middle bile duct cancer. Because abdominal drainage revealed bile leakage 5 days postoperatively, leakage at the site of cholangiojejunostomy was diagnosed, and continuous aspiration was performed. Seventeen days postoperatively, pus was discharged through the abdominal drain. Because bleeding was detected by abdominal drainage, and shock ensued 20 days postoperatively, emergency abdominal angiography was carried out to identify the bleeding site. A false aneurysm in the proper hepatic artery and extravasation from the gastroduodenal artery stump were recognized, and therefore, the proper hepatic artery and common hepatic artery were embolized at a site distal to the false aneurysm using microcoils. Celiac arteriography after transcatheter arterial embolization (TAE) did not show extravasation, and revealed blood flow from the right inferior phrenic artery to the liver. Liver function was normal after TAE, and the patient recovered and was discharged from the hospital 54 days postoperatively. This paper presents a patient in whom intraabdominal bleeding due to leakage at the site of cholangiojejunostomy complicated by infection was successfully treated by hemostasis with TAE.- - - - - - - - - - ranking = 0.45314786384988keywords = cancer (Clic here for more details about this article) |
8/186. Waldeyer's ring lymphoma presenting as massive oropharyngeal hemorrhage.A case report of a patient presenting with massive oropharyngeal hemorrhage originating from lymphoma of the tonsil and it's management is discussed. Locally advanced or recurrent squamous cell carcinoma may manifest with massive oropharyngeal hemorrhage, however, it is unusual for Waldeyer's ring lymphoma to present in this fashion. Management of oropharyngeal malignancies presenting in this manner includes airway control, control of hemorrhage, and biopsy of the tumor. hemorrhage control is provided by surgical exploration or intraarterial embolization. Extranodal lymphoma of the head and neck is not uncommon and is thoroughly discussed in the medical literature. hemorrhage into the upper aerodigestive tract is occasionally observed in the patient with head and neck cancer. It usually occurs, however, in patients with squamous cell carcinoma that have been previously treated or in patients with locally advanced cancers. A comprehensive review of the literature has revealed no other reports of head and neck lymphoma presenting with massive oropharyngeal hemorrhage.- - - - - - - - - - ranking = 0.90629572769976keywords = cancer (Clic here for more details about this article) |

10/186. A case of hemorrhagic cyst of the pancreas resembling the cystic endometriosis.A 47-year-old Japanese woman with a history of epigastric pain and a recent episode of acute pancreatitis (back pain, nausea, and vomiting) and anemia was found to have a pancreatic cyst of the tail on CT-scan and ultrasonography. Especially, ultrasonography revealed the papillary solid lesion in the cyst. With the tentative diagnosis of a cystic neoplasm, distal pancreatectomy was performed. Histological examination of sections showed massive hemorrhage, surrounded fibrous connective tissue, and numerous macrophages with hemosiderin deposits; these histological findings resembled cystic endometriosis. The clinicopathological features and pathogenesis of the pancreatic endometrial cyst are discussed.- - - - - - - - - - ranking = 0.074131886746594keywords = neoplasm (Clic here for more details about this article) |
