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.

Subarachnoid hemorrhage (SAH) due to ruptured posterior cerebral artery (PCA) intracranial arterial dolichoectasia (IADE) is very rare. As these lesions are difficult to treat microsurgically, neurointervention is preferred because the dolichoectatic artery does not have a clear neck, and the surgical field of view was deep seated with the SAH. However, in some cases, neurointervention is difficult due to anatomical variation of the blood vessel to access the lesion. In this case, a 30-year-old male patient presented with a ruptured PCA IADE and an aortic arch anomaly. Aortic arch anomalies render it difficult to reach the ruptured PCA IADE via endovascular treatment. The orifice of the vertebral artery (VA) was different from the usual cases, so it was difficult to find the entrance. After only finding the VA and arriving at the lesion along the VA, trapping was performed. Herein, we report the PCA IADE with aortic arch anomaly endovascular treatment methods and results.

Intracranial aneurysms arise in 1-2% of the population and usually present as hemorrhagic strokes. Spontaneous thrombosis of a ruptured intracranial aneurysm occurs in 1-3% and most commonly in giant aneurysms, with complete thrombosis in just 13-20% of the cases. Thrombosis of smaller aneurysms is rare. Here we present a case of a patient who presented with a ruptured intracranial aneurysm that subsequently thrombosed, discovering a neighboring de-novo aneurysm during follow-up. We hypothesized that after thrombosis, the hemodynamic characteristics that contributed to the formation of the first aneurysm were replicated.

When aneurysmal subarachnoid hemorrhage due to multiple aneurysms is suspected, identifying the rupture site is essential to determine the exact surgical site, but it may not be easy. Even if embolization is adequately performed, complications may remain. Typical complications include rebleeding and hydrocephalus in the early phase and delayed cerebral ischemia in the delayed phase. Herein, we describe a case of rupture of an intracranial aneurysm after performing embolization for a different ruptured intracranial aneurysm in a patient with multiple intracranial aneurysms. Patients with multiple intracranial aneurysms need to be considered for closer observation than those with a single ruptured intracranial aneurysm, even if the patient's prognosis is good.

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.
