1/152. Intraoperative left ventricular perforation with false aneurysm formation.Two cases of perforation of the left ventricle during mitral valve replacement are described. In the first case there was perforation at the site of papillary muscle excision and this was recognized and successfully treated. However, a true ventricular aneurysm developed at the repair site. One month after operation rupture of the left ventricle occurred at a second and separate site on the posterior aspect of the atrioventricular ring. This resulted in a false aneurysm which produced a pansystolic murmur mimicking mitral regurgitation. Both the true and the false aneurysm were successfully repaired. In the second case perforation occurred on the posterior aspect of the atrioventricular ring and was successfully repaired. However, a false ventricular aneurysm developed and ruptured into the left atrium producing severe, but silent, mitral regurgitation. This was recognized and successfully repaired. The implications of these cases are discussed.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
2/152. Transesophageal echocardiography and concurrent coronary angiography for the rapid assessment of papillary muscle rupture.echocardiography with color flow imaging is valuable for identifying mechanical complications of myocardial infarction. Transesophageal echocardiography is useful for critically ill patients in whom transthoracic imaging is often insufficient. A case of papillary muscle rupture is presented in which transesophageal echocardiography was performed concurrently with coronary angiography. The detailed information obtained from two-dimensional and color flow imaging eliminated the need for diagnostic right heart catheterization and left ventriculography. Transesophageal echocardiography used in this manner can facilitate expeditious surgical management.- - - - - - - - - - ranking = 5keywords = muscle (Clic here for more details about this article) |
3/152. Case report: rupture of a gastric varix in liver cirrhosis associated with glycogen storage disease type iii.glycogen storage disease type iii, or Cori's disease, is caused by a deficiency of amylo-1,6-glucosidase (debranching enzyme), which leads to the storage of an abnormal glycogen in the liver and in skeletal and heart muscle. glycogen storage disease type iii is usually characterized by hepatic symptoms, growth failure and myopathy. Even though liver cirrhosis is reported, portal hypertension is a rare complication of this disease. We describe the case of a glycogen storage disease type III patient who was diagnosed at 3 years of age and developed complications (liver cirrhosis and rupture of a gastric varix) at 31 years of age. We discuss the histological progression to cirrhosis of the liver and describe the liver enzyme profile at 3 and 31 years of age.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
4/152. Ruptured primary splenic angiosarcoma into the colon. Presentation as anal bleeding.A 71-year-old woman presented with a six month history of constipation and abdominal discomfort, with anal bleeding during the last days. ultrasonography and CT-scan of the abdomen showed a large heterogeneous mass that was located in the splenic region, but the nature and origin of the tumour could not be clearly established preoperatively. The clinical diagnosis was of abdominal tumour with colonic and splenic involvement, and a left hemicolectomy and splenectomy were performed. Pathologic examination revealed a primary angiosarcoma of the spleen with penetration and fistulization of the tumour into the large bowel. The patient received adjuvant radiation therapy, but she died of extensive metastastic disease from her primary angiosarcoma of the spleen nine months after surgery. In summary, splenic angiosarcoma is very difficult to diagnose preoperatively. This highly aggressive neoplasm has an overall poor prognosis, specially if it is associated with rupture and haemoperitoneum. As this case highlights, unusual forms of rupture may lead to atypical clinical presentations, increasing even more the difficulty in the diagnosis.- - - - - - - - - - ranking = 0.056986230708829keywords = neoplasm (Clic here for more details about this article) |
5/152. hemoperitoneum due to a ruptured gastric stromal tumor.BACKGROUND/AIMS: gastrointestinal stromal tumors form a group of uncommon neoplasms originated from pluripotential mesenchymal cells. Many patients are asymptomatic and the tumor is discovered during an abdominal operation. Massive intraperitoneal bleeding is an exceptional complication associated with high mortality rates. Our aim is to report a case of a gastric stromal tumor in an 83-year-old patient presenting with intraperitoneal hemorrhage and hypovolemic shock, successfully operated. methods: Emergency laparotomy showed a hemoperitoneum caused by rupture of a large exogastric tumor attached to the greater curvature. Total gastrectomy and esophagojejunostomy was performed. RESULTS: Histological examination revealed proliferation of spindle-shaped cells but immunocytochemistry failed to identify specific markers of smooth muscle and neural cells. diagnosis of a gastric stromal tumor was made. Postoperative evolution was uncomplicated. CONCLUSION: Gastric stromal tumor is a relatively rare neoplasm of mesenchymal origin whose nature and prognosis is unclear.- - - - - - - - - - ranking = 1.1139724614177keywords = muscle, neoplasm (Clic here for more details about this article) |
6/152. trisomy 12 in juvenile granulosa cell tumor of the ovary during pregnancy. A report of two cases.BACKGROUND: Granulosa cell tumors constitute only 5% of ovarian neoplasms, and their coexistence with pregnancy is extremely rare. Juvenile granulosa cell tumor has a good prognosis if it is confined to the ovary, but this type behaves more aggressively than the adult type at advanced stages. CASES: We report on successful completion of two singleton pregnancies and deliveries of normal infants in two young women with juvenile granulosa cell tumor diagnosed and treated during pregnancy. This tumor has rarely been described in association with pregnancy. The presence of trisomy 12 as a single chromosomal abnormality was detected in these two tumors. Both tumors were localized strictly to the ovary, so conservative surgery was applied and proved sufficient to remove all tumor tissue. Follow-up showed no signs of recurrence 18 and 53 months after the interventions. CONCLUSION: These cases support the contention that trisomy 12 is a nonrandom chromosome abnormality in juvenile granulosa cell tumors and that pregnancy may affect nuclear stability in this tumor.- - - - - - - - - - ranking = 0.056986230708829keywords = neoplasm (Clic here for more details about this article) |
7/152. 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 = 0.056986230708829keywords = neoplasm (Clic here for more details about this article) |
8/152. Subvalvular left ventricular aneurysm following mitral valve replacement.Two cases are presented which represent different aspects of damage to the posterior wall of the left ventricle following mitral valve replacement. In the first case rupture of the ventricle occurred in the immediate postoperative period with a fatal result, while in the second, delayed aneurysm formation occurred with embolic and haemodynamic complications. This patient also did not survive. A review of the literature reveals four similar cases previously recorded. Possible aetiological factors are considered, including operative trauma, ischaemic damage, rupture of unsupported muscle, previous surgery with the development of pericardial adhesions and fixing of the valve ring, and finally abscess formation. The indications for operative intervention and possible complications of the aneurysm are noted.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
9/152. Heterotopic pancreas of the esophagus masquerading as Boerhaave's syndrome.Heterotopic pancreas (HP) of the esophagus is rare. We report a patient with HP of the esophagus and review the presentation, treatment, and results of the nine previously reported cases. Two patients had cancer. This high incidence raises concerns that HP of the esophagus may be premalignant. Because surveillance endoscopy is not possible, all known or suspected esophageal HP should be treated surgically.- - - - - - - - - - ranking = 0.23980751796325keywords = cancer (Clic here for more details about this article) |
10/152. Acute compartment syndrome after rupture of the medial head of the gastrocnemius muscle.rupture of the gastrocnemius muscle is an uncommon injury, with most cases occurring in athletically active individuals. The presentation of a gastrocnemius rupture is the acute onset of calf pain and subsequent ecchymosis. Most of these injuries can be treated symptomatically with good results. We present an unusual case of gastrocnemius muscle tear complicated by acute compartment syndrome. physicians need to be aware of this potentially devastating complication of gastrocnemius rupture.- - - - - - - - - - ranking = 6keywords = muscle (Clic here for more details about this article) |
