A 6 yers old German Shepherd dog was diagnosed to a ruptured gallbladder subsquently causing a diffuse peritonitis with bile-contaminated ascites. Surgical exploration could not determine its causes of pathogenesis. A marked leukocytosis and increased alkaline phosphotase were the pronounced clinical pathologic features. Delayed surgical exploration was critical therapeutic failure of this particular case. An immediate surgical intervention could be a life saving therapy of choise. The author report an uncommon clinical case presentation of the ruptured gallbladder in a dog and an importance of immediate surgical correction.

Aneurysm of the sinus of Valsalva is an uncommon cardiac anomaly, usually congenital in origin, which may occur as an isolated defect or in conjunction with other cardiac malformation. This report is a case of a ruptured sinus of Valsalva aneurysm with ventricular septal defect in a 18-year-old female patient who complained progressive exertional dyspnea. She underwent operative management using total cardiopulmonary bypass. The fistula originated from the right coronary sinus and ruptured into the right ventricle and coexistent lesion was supracristal ventricular septal defect. The repair was done through aortic and right ventricular approach. The ruptured sinus of Valsalva was closed with pledget suture and the ventricular septal defect was closed with patch. The postoperative result was good.

Middle cerebral artery [MCA] aneurysms are a common source of subarachnoid hemorrhage [SAH]. But, ruptured distal MCA aneurysm is very rare, and their clinical and radiological features are poorly understood. Microsurgical repair remains the most common method used to treat distal MCA aneurysm, even though endovascular coiling has been favored recently. We report our experience of successful coiling for ruptured distal MCA aneurysm, In selected patients, coiling may be a good treatment option for ruptured distal MCA aneurysm.

Here, we present a case of ruptured sinus Valsalva aneurysm with fistulous communication between the right coronary aortic sinus and the right ventricle in 8 year old boy. Ruptured sinus Valsalva aneurysm is rare. And several reports are describing its pathophysiologic features, clinical findings and management. This patient was asymptomatic and the physical examination revealed palpable thrill and Grade III pansystolic murmur at the 3rd and 4th intercostal space along the left sternal border. There was an oxygen step up from right atrium into right ventricle on the cardiac catheterization reports. On 15th July 1981, an open heart surgery was performed and we found ruptured right coronary sinus Valsalva aneurysm into the right ventricle, which was managed successfully by doing direct pledget sutures. The postoperative course was uneventful.

Supratentorial dermoid cysts are uncommon to develop in the cavernous sinus. We present a ruptured dermoid cyst of the cavernous sinus extending into the posterior fossa. The patient was a 32-year-old female who complained occipital headache, blurred vision, and tinnitus over 4 years. Brain magnetic resonance (MR) imaging revealed an enhanced tumor in the right cavernous sinus extending into the right temporal base and the posterior fossa with findings of ruptured cyst. Surgical resection was performed, and pathological findings were confirmed to be a dermoid cyst. We report a second case with ruptured dermoid cyst of the cavernous sinus extending into the posterior fossa.

Over the past 8 years, from 1985 to 1992, 6 patients with ruptured aneurysm of the sinus of Valsalva underwent open heart surgery in the Department of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. Five aneurysms originated from the right coronary sinus and ruptured into right ventricle and one from noncoronary sinus into RA. Ventricular septal defects were associated with 5 cases and one had no associated cardiac anomalies. The ruptured aneurysms were repaired through double incisions in 3 cases, through aortotomy in 2 cases and through right atriotomy in 1 case. There were no early and late complications and follow up results are excellent in all patients.

An influence analysis on multiple steam generator tube rupture (mSGTR) followed by an unmitigated station blackout is performed to compare the plant responses according to the number of ruptured u-tubes under the assumption of a total of 10 ruptured u-tubes. In all calculation cases, the transient behaviour of major thermal-hydraulic parameters, such as the discharge flow rate through the ruptured u-tubes, reactor header pressure, and void fraction in the fuel channels is found to be overall similar to that of the base case having a single SG with 10 u-tubes ruptured. Additionally, as the conditions of low-flow coolant with high void fraction in the broken loop continued, causing the degradation of decay heat removal, the peak cladding temperature (PCT) would be expected to exceed the limit criteria for ensuring nuclear fuel integrity. However, despite the same total number of ruptured u-tubes, because of the different connection configuration between the SG and pressurizer, a difference is foud in time between the pressurizer low-level signal and reactor header low-pressure signal, affecting the time to trip the reactor and to reach the PCT limit. The present study is expected to provide the technical basis for the accident management strategy for mSGTR transient conditions of CANDU-6 plants.

Objective : The International Study of Unruptured Intracranial Aneurysms (ISUIA) reported that the 5-year cumulative rupture rate of small unruptured aneurysms less than 7 mm in diameter is very low depending on the aneurysm's location. However, we have seen a large number of ruptured aneurysms less than 7 mm in clinical practice. The purpose of this study was to review our experience and to measure the size and location at which aneurysms ruptured in our patient population. Methods : We reviewed the characteristics of aneurysms, such as size and location, from the original angiograms of patients who were admitted to our hospital between January 2004 and December 2007. All aneurysms were treated surgically or through endovascular procedures. Results : Interventional or surgical treatment was given to a total of 889 patients, including 568 females and 321 males. At the time of our study, 627 cases were ruptured aneurysms and 262 cases were unruptured aneurysms. Of the ruptured cases, the mean diameter of the aneurysm was 6.28 mm. We found that 71.8% of ruptured aneurysms were smaller than 7 mm in diameter, and 87.9%, were smaller than 10 mm. Based on location, the data show that anterior communicating artery aneurysms most often presented with rupture sizes less than 7 mm (76.8%) and 10 mm (92.1%) in diameter. Most ruptured aneurysms were less than 7 mm in size, although recent studies have noted that small aneurysms are less likely to rupture. Conclusion : Although the natural history of unruptured intracranial aneurysms remains controversial, the aneurysm size and location play a signigicant role in determining the risk of rupture. Larger sample sizes and a long term study are needed to reveal the natural history and the rupture risk of unruptured intracranial aneurysms because the size of most ruptured aneurysms was less than 7 mm in diameter in our series.

Bilateral abducens nerve palsy related to ruptured aneurysm of the anterior communicating artery (ACoA) has only been reported in four patients. Three cases were treated by surgical clipping. No report has described the clinical course of the isolated bilateral abducens nerve palsy following ruptured ACoA aneurysm obliterated with coil. A 32-year-old man was transferred to our institution after three days of diplopia, dizziness and headache after the onset of a 5-minute generalized tonic-clonic seizure. Computed tomographic angiography revealed an aneurysm of the ACoA. Magnetic resonance imaging showed focal intraventricular hemorrhage without brain stem abnormalities including infarction or space-occupying lesion. Endovascular coil embolization was conducted to obliterate an aneurysmal sac followed by lumbar cerebrospinal fluid (CSF) drainage. Bilateral paresis of abducens nerve completely recovered 9 weeks after ictus. In conclusion, isolated bilateral abducens nerve palsy associated with ruptured ACoA aneurysm may be resolved successfully by coil embolization and lumbar CSF drainage without directly relieving cerebrospinal fluid pressure by opening Lillequist's membrane and prepontine cistern.

The purpose of this paper is to present author's experience with 6 cases of ruptured aneurysm of sinus of Valsalva which were treated surgically during last 10 years. Among the 6 cases, 5 were male and one was female. All of them originated from the right coronary sinus and 5 cases were ruptured into the RV while remained one into RA. The diagnosis was obtained in 4 cases by cineangiocardiogram. Clinically, we had difficulties in differential diagnosis with combined cases of VSD with A.I. and had special experience in its differentiation during cardiac catheterization. By simultaneous trans-venous and trans-arterial catheterization, identified two catheter tips in the RV, and pull back tracing obtained aortic pressure directly from RV, and RA from RV pressure which were benefit in confirm ruptured aneurysm of the aortic sinus. Surgical correction was performed by means of direct suture closure or combined Teflon pledget Of patch enforcement graft after aneurysm resection by trans-RA or trans-RV approach. All patients had no history of bacterial endocarditis, syphilis, or tuberculosis and operative findings revealed intact coronary sinus except involved one moreover 3 cases combined with high VSD which uggested congenital in origin although pathologic reports revealed only fibrosis. Post-operative course were uneventful in all cases but one who had bleeding and 2 months to 9 years follow up results were good and spend their usual life in all cases.
