Some aneurysms with peculiar shapes, large sized or in unusual location cannot be obliterated by ordinary methods. We present four cases using two kinds of fenestrated clips. There were 4 aneurysms in the 4 patients:3 saccular and 1 fusiform aneurysm. Two aneurysms were located in anterior communicating artery, one left carotico-opthalmic artery, and one distal middle cerebral artery. All of the aneurysms were successfully obliterated. Our results suggest that the various shape of fenestrated clips may be benefit for clipping difficult aneurysms, which would not be clipped with ordinary one.

The authors described different type of aneurysms in the distal anterior cerebral artery(DACA), which is difficult to approach surgically. there are anomalies of distal anterior cerebral artery in about one fourth and narrow space, which made more careful surgical dissection. We experienced 7 cases of DACA aneurysm, 6 cases of which were treated surgically through the interhemispheric approach via the unilateral frontal paramedian craniotomy on the non-dominant side. Surgical results were anatomical complexities, modern microsurgical technique aided by microscope make the approach more exactly and safely.

3.A2 Anomaly Associated with Anterior Cerebral Artery Aneurysm.
Korean Journal of Cerebrovascular Disease 2001;3(2):159-162
Seven cases of A2 anomaly including azygous A2 and accessory A2 were observed during aneurysm surgery. We present case histories, angiograms and operative descriptions, and discuss with the clinical significance of the anomaly. The recognition of the anatomic variations prior to clip placement for anterior cerebral artery aneurysm is emphasized.

Aneurysmal ruptures associated with middle cerebral artery(MCA) anomalies, such as a duplicated MCA and an accessory MCA, are quite rare. The authors reviewed the clinical relevance and possible etiology of these anomalies.

Journal of Korean Neurosurgical Society 2010;48(5):434-437
We report a unique case of bilateral mirror image M1 aneurysms, one of which was an unruptured aneurysm arising from the proximal end of right middle cerebral artery fenestration with long loop and the other ruptured aneurysm from the contralateral side. We clipped ruptured aneurysm first and unruptured one in three months after the first operation. The difficulties of identifying this unusual vascular anomaly and possible problems during the surgery of an aneurysm at the site of fenestration are discussed with a review of the literature.

The azygous anterior cerebral artery (ACA) is a rare type of ACA anomaly. In the conventional angiography, cognition of its realm is difficult without considerable reading. Clinically, misreading its nature causes confusion during the surgical approach to its associated cerebral aneurysm. We report this rare clinical experience with an angiographic and surgical review.

Intracranial aneurysms in the neonate are very rare and their clinicopathological findings remain unclear. We report a 26-day-old premature neonate who underwent microsurgical clipping on the ruptured middle cerebral artery bifurcation aneurysm successfully with a review of relevant literature.

Endovascular treatment has been increasingly performed for unruptured intracerebral aneurysms. However, thromboembolic complications, which develop mostly within 48 hours after the procedure, are the most common and major complications of endovascular treatment. We present a rare case of delayed symptomatic thromboembolism in an ischemic stroke patient who had undergone coil embolization for unruptured middle cerebral artery (MCA) aneurysm.

The authors reviewed angiographic findings of 96 cases of ruptured anterior communicating artery aneurysms that were operated at the Department of Neurosurgery of Hanyang University Hospital from Jan. 1986 to June 1990. The results were summarized as follows ; 1) Asymmetricity of caliber of A1 was observed in 71.9%(69/96) and which was 3 times more frequent than that of reported incidence of control group(2~23%). 2) The incidence of predominance of left A1 was 54.2%(53/96) and that of right A1 was 17.7%(17/96). Among them, predominant A1 was operated as afferent artery of aneurysm in 94.2%(65/69). 3) Of 69 cases in which a unilateral A1 showed predominance, the direction of aneurysm was opposite to the side of predominant A1 in 66.7%(46/69) and ipsilateral to the predominant A1 in only 2.9%(2/69). 4) Above findings suggest that it is desirable to approach the anterior communicating artery aneurysm via the side of predominant A1 when the direction of aneurysm is uncertain on cerebral angiogram.

We report two cases of reruptured anterior communicating artery aneurysm during cerebral angiography in one aged 80 years and the other aged 59 years. Both patients had emergency angiography on Day 0, within 5 hours of the latest rupture. The prognosis was very poor. We stressed the importance of the time interval between the latest rupture and angiography.
