We experienced 6 patients with the sinus Valsalva aneurysm rupture during last 12 years [Jan. 1977-Sep. 1989]. Of them. 5 cases were reviewed. They consist of 3 males and 2 females, and the age ranged from 12 years to 40 years with the mean age of 25 years. 4 patients showed congestive heart failure symptoms. The diagnosis was made by 2D-Echo and cine-angiogram. In 4 patients. sinus Valsalva aneurysm ruptured from the Rt. coronary sinus to the Rt. ventricle, and in one from non-coronary sinus to the Rt. atrium. In 2 cases, resection of the aneurysm and simple stitch closure was made. Resection of the aneurysm k patch closure and AVR in one, closure of the fistula, AVR and patch closure of the associated VSD in one, and closure of the fistula, AVR k TVR in one were made in another 3 cases. There was no postoperative mortality case.

In treating uncomplicated abdominal aortic aenurysm, endovascular aortic aneurysm repair (EVAR) has been employed as a good alternative to open repair with low perioperative morbidity and mortality. However, the aneurysm can enlarge or rupture even after EVAR as a result of device failure, endoleak, or graft migration. We experienced two cases of aneurismal rupture after EVAR, which were successfully treated by surgical extra-anatomic bypass.

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.

Rapidly developed de novo aneurysm is very rare. We present a rapidly developed and ruptured de novo anterior communicating aneurysm 8 days after the rupture of another aneurysm. This de novo aneurysm was not apparent in the initial 3-dimensional computed tomography and digital subtraction angiography. We reviewed the literature and discussed possible mechanisms for the development of this de novo aneurysm.

Objectives : Despite advance in the surgical treatment of the intracranial aneurysm, we have to be surgical complication. The aim of this report is to evaluate the complication and its management in intracranial aneurysm operation. Methods : We reviewed our exprience with interesting cases of surgical complication of intracranial aneurysm : 1) rebleeding, 2) intra-operative premature rupture, 3) missed aneurysm in angiography, 4) vasospasm. Results : The risk of rebleeding was not related to the patients' initial comdition, but all other intracranial complications occurred significantly more often in patients graded poor compared with patients in good clinical condition. Rebleeding before early surgery remains as major cause of unfavorable outcome. The causes of intraoperative premature ruptures were as follows : 1) dural opening and arachnoid opening(8.3%), 2) hematoma removal(12.5%), 3) brain retraction(16.7%) 4) aneurysm dissection(62.5%). The double suction technique and primary hemostasis using a small piece of cotton or temporary clip resulted in good outcome even in cases with premature rupture. The incidence of missed aneurysm in angiography occurred in 10%. The causes were as thrombosed aneurysm, vasospasm on feeder artery. The most common missed aneurysm is also the most common aneurysm(anterior communicating artery aneurysm). The repeated angiography were documented in missed aneurysm. Balloon angioplasty is superior topapaverine for treatment of proximal vessel vasospasm by viture of a more sustained effect on the vessel. Papaverine can be useful as an adjunct to ballon angioplasty and also for the treatment of distal vessels that are not accessible for ballon angioplasty. Conclusion : The minimization of the complications and active treatment can reduced the mortality and morbidity of ruptured aneurysm patients.

Objective : To investigate the morphological and hemodynamic parameters associated with middle cerebral artery (MCA) bifurcation aneurysm rupture. Methods : A retrospective study of 67 consecutive patients was carried out based on 3D digital subtraction angiography data. Morphological and hemodynamic parameters including aneurysm size parameters (dome width, height, and perpendicular height), longest dimension from the aneurysm neck to the dome tip, neck width, aneurysm area, aspect ratio, Longest dimension from the aneurysm neck to the dome tip (Dmax) to dome width, and height-width, Bottleneck factor, as well as wall shear stress (WSS), low WSS area (LSA), percentage of LSA (LSA%) and energy loss (EL) were estimated. Parameters between ruptured and un-ruptured groups were analyzed. Receiver operating characteristics were generated to check prediction performance of all significant variables. Results : Sixty-seven patients with MCA bifurcation aneurysm were included (31 unruptured, 36 ruptured). Dmax (p=0.008) was greater in ruptured group than that in un-ruptured group. D/W (p<0.001) and the percentage of the low WSS area ($0.09{\pm}0.13$ vs. $0.01{\pm}0.03$, p<0.001) were also greater in the ruptured group. Moreover, the EL in ruptured group was higher than that in unruptured group ($6.39{\pm}5.04$ vs. $1.53{\pm}0.86$, p<0.001). Multivariate regression analysis suggested D/W and EL were significant predictors of rupture of MCA bifurcation aneurysms. Correlation analyses revealed the D/W value was positively associated with the EL (R=0.442, p<0.01). Conclusion : D/W and EL might be the most two favorable factors to predict rupture risk of MCA bifurcation aneurysms.

For high-risk patients, endovascular aortic aneurysm repair (EVAR) is a good option but may lead to serious complications, which should be addressed immediately. A 75-year-old man with a history of abdominal surgery underwent EVAR for an aneurysm of the abdominal aorta and iliac arteries. During EVAR, iliac artery rupture and graft limb occlusion occurred, and they were successfully managed by the additional deployment of an iliac stent graft and balloon thrombectomy, respectively. We, herein, report a rare case of the simultaneous development of the two fatal complications treated by the endovascular technique.

A rupture of a dissecting aneurysm of the aorta is life threatening disease and calls for emergency surgical treatment. The author recently experienced one case of ruptured dissecting aneurysm of the descending thoracic aorta complicated with left hemothorax who was recovered after emergency operation of Aug. 11, 1976. The patient was a 43 years old farmer with known hypertension [260/120] for 20 years but without any venereal disease and had experienced sudden throbbing chest pain. Chest film and aortogram revealed this case ruptured aneurysm of descending thoracic aorta complicated with left hemothorax. In this case, large dissecting aneurysm extend from proximal part of left subclavian artery below diaphragm and involved with 3.0 and 4.0cm sized elliptical rupture in proximal part of descending thoracic aorta. And so, neither fenestration procedure nor replacement of dacron artificial vessel was suitable for this case. Finally, only the rupture site of aneurysm was treated by covering with fibrous pleura and teflon patch. The post-operative management of this case was planned to control hypertension with antihypertensive drugs. The follow-up was possible up to date about 2months. The patient has been doing well with ordinary activities except mild chest discomfort.

Rupture or laceration of the aorta is a more common result of nonpenetrating traumatic injury than is generally appreciated. If the lesion is promptly diagnosed, a appropriate surgical treatment may be life-saving. Diagnosis may be difficult and at times the rupture may remain clinically silent for variable period.< A 34 - year old male patient had sustained steering wheel injury to his chest during automobile accident 8 weeks prior to admission. The diagnosis of traumatic aneurysm of the aorta was delayed as he was asymptomatic. Surgical repair of false aneurysm of the descending aorta was successfully performed by partial cardiopulmonary bypass through the femoral artery and vein.

This is a case report of surgically treated rupture of Valsalva Sinus aneurysm combined with VSD. He has been relatively healthy until about one month before admission, when during bath, he felt abruptly palpitation, left chest pain and exertional dyspnea. These symptoms have progressed. On admission, thrill was palpable and continuous machinery murmur was audible on 2nd and 3rd intercostal space along the left sternal border. A rupture of Valsalva`s sinus aneurysm was confirmed by aortography and echocardiography but a small VSD was found by cardiotomy in open heart surgery. On 11th Sep. 1978, open heart surgery was performed. Valsalva`s sinus aneurysm came out from right coronary aortic sinus and ruptured into the right ventricle. It sized 1.2X1.5X1.5 cm. Ruptured opening was noted on apex of aneurysm [0.8X0.8cm], VSD [1. 0X0. 3cm in size] was just below the aortic annulus. The aneurysmal sac was removed on neck. After that, VSD and aneurysmal orifice were closed together with interrupted mattress sutures on same plane. The postoperative course was uneventful and discharged three weeks after open heart surgery.
