  • Objectives : The best results of treating intracranial aneurysms can be achieved with treating aneurysm before they rupture. Some recent reports about the risk of the bleeding of the unruptured intracranial aneurysm(UIA) being too low(0.05% per year) compared with 1~2% of the previously reported bleeding probability, casts the question about the need for treatment of the UIAs. The purpose of this report is to review the recent reports about the risk of rupture of the UIAs and to assess the morbidity and mortality associated with surgical treatment for UIAs.

  • For surgical minimalism to reduce iatrogenic traumatization, a supraorbital keyhole approach has already been successfully applied to treat many unruptured anterior circulation aneurysms. However, using this minimal approach also raises several technical concerns due to the small cranial opening and cosmetic impact of a facial incision. Yet, such technical limitations can be overcome by using favorable surgical indications, slender surgical instruments, and optimized surgical techniques, while excellent cosmetic outcomes can be achieved using a short skin incision located <1 cm from the supraorbital margin, reconstruction of any bone defects around the bone flap, and meticulous wound closure. Thus, given such reassuring surgical results, in terms of the clipping status, neurological effects, and cosmetic outcomes, any concerns can be transitioned into confidence.

  • Ceil embolisation technique has been used to treat the intracranial aneurysms. Microcoils inserted into the aneurysm sac induce the blood flow stagnation inside the aneurysm sac, which causes the thrombus formation and embolisation of aneurysm. Since the intraaneurysmal flow patterns affect the embolisation process, we want to measure the flow field for different locations of coil inside the aneurysm sac . Lateral aneurysm models are manufactured using rapid prototyping, and the velocity fields are measured using particle image velocitimeter. Distally blocked models showed less flow into the aneurysm sac comparing to proximally blocked models. Also blocking the neck of aneurysm showed better inflow blocking comparing to blocking the dome of aneurysm. These results suggest that distal neck should be the preferred locations of coil for aneurysm embolisation.

  • Celiac artery aneurysms are rare, their incidence being reported as only 4% of all visceral artery aneurysms. Atherosclerosis and medial degenerative changes are recognized main pathogenesis. They are usually asymptomatic and diagnosed incidentally, but the mortality rate of ruptured celiac artery aneurysm is approximately 80%. So one should give an aggressive surgical aid to the patients. We report 2 cases of celiac artery aneurysm which were successfully treated by elective aneurysmorrhaphy and anerysmectomy with aortoceliac bypass graft.

  • Giant serpentine aneurysms are rare and have distinct angiographic findings. The rarity, large size, complex anatomy and hemodynamic characteristics of giant serpentine aneurysms make treatment difficult. We report a case of a giant serpentine aneurysm of the right middle cerebral artery (MCA) that presented as headache. Treatment involved a superficial temporal artery (STA)-MCA bypass followed by aneurysm resection. The patient was discharged without neurological deficits, and early and late follow-up angiography disclosed successful removal of the aneurysm and a patent bypass graft. We conclude that STA-MCA bypass and aneurysm excision is a successful treatment method for a giant serpentine aneurysm.

  • Rupture of the aorta following blunt trauma of the thorax may occur more frequently than has generally been recognized. Actual complete transection of the aorta usually results in immediate death but varying degrees of lesser disruption permit increased chance of survival. Chronic traumatic aneurysms are so designated following a period of 3 months from the traumatic incident. The exact time required for the acute process and hematoma to convert into an aneurysm is unknown. Because a thoracic surgeon encounters so few of these aneurysms, it is difficult for him to arrive at sound dicta of management from his personal experience. It is not surprising that controversy exists concerning the therapeutic approach to the aneurysm which is asymptomatic and is discovered months or years after the causative injury. In the hope of improving the surgical treatment of patients with this condition, we reported one case with chronic traumatic aneurysm of the descending thoracic aorta.

  • The incidence of superior cerebellar artery aneurysm is less than 1% of all intracranial aneurysms. These aneurysms usually occur at the junction between the superior cerebellar artery and the basilar trunk, however, seldom occur distally. We present a extremely rare case of distal superior cerebellar artery aneurysm arising at the junction between anterior pontine segment and ambient segment.

  • Carotid occlusion is an inevitable therapeutic modality for the treatment of complex aneurysms such as giant, traumatic, and intracavernous aneurysms. Late complications of carotid occlusion include 'de novo' aneurysm formation at a distant site because of hemodynamic changes in the circle of Willis. We report a case of de novo aneurysm in a vessel that appeared to be normal on initial angiography. The patient developed an anterior communicating artery aneurysm and marked growth of a basilar bifurcation aneurysm 9 years after trapping of the left internal carotid artery for the treatment of a ruptured large saccular aneurysm involving ophthalmic and cavernous segments. We propose that patients who undergo therapeutic carotid occlusion should be periodically followed by magnetic resonance angiography or computed tomographic angiography to evaluate the possibility of de novo aneurysm formation; this advice is in line with previous reports.
