We report a patient with a ruptured vertebral artery (VA) dissecting aneurysm that was treated by internal trapping of the aneurysm and parent artery using detachable coils with subsequent antegrade recanalization of occluded vertebral artery during the follow-up period. A 38-year-old man was admitted with a ruptured right VA dissecting aneurysm just distal to origin of right posterior inferior cerebellar artery. The dissected segment of the VA was occluded by coil embolization. The 14 months follow-up angiography showed that dissected aneurysm was completely occluded, but the parent artery was recanalized in an antegrade fashion. Based on this unique case, the authors suggest that careful angiographic follow-up of dissecting aneurysm is required, even in patients successfully treated with endovascular occlusion of the affected artery and aneurysm.

Regarding the bilateral vertebral artery [VA] dissecting aneurysms, treatment strategy remains controversial because there have not been enough cases to reach a conclusion on the best treatment. We present a patient underwent staged microsurgical trapping and endovascular coiling for each dissecting aneurysm of bilateral VA presenting subarachnoid hemorrhage [SAH]. The ruptured side was managed by VA trapping procedure without any neurological deficit. Postoperative cerebral angiography revealed patent right PICA without filling of previous right dissecting aneurysm and spontaneous occlusion of the left dissecting aneurysm one month after trapping procedure. However, follow-up angiography revealed recanalization and growing of the left VA dissecting aneurysm one year after the operation. The patient underwent endovascular embolization using GDC for the proximal occlusion of the left VA and postoperative course was uneventful.

Anterior cerebral artery[ACA] dissecting aneurysms are extremely rare and optimal treatment remains unclear. The majority of cases manifest as cerebral infarction or as intracranial bleeding. The authors report two cases of ACA dissecting aneurysm, one with a large partially thrombosed gradually growing aneurysm and one with a cerebral infarction in the ACA territory. The patient with a large aneurysm was treated by trapping the aneurysm, and the patient with infarction by conservative management. We report on two cases of dissecting aneurysm of the ACA and include a review of pertinent literature.

The dissecting aneurysms of the posterior cerebral circulation arise most commonly from the vertebral artery and occasionally extend to the posterior inferior cerebellar artery[PICA]. The dissecting aneurysm localized in the PICA without involving the vertebral artery is rare. We present a PICA dissecting aneurysm that had kaleidoscopic clinical course of bleeding, occlusion, and recanalization before the surgery. The patient had serial follow-up angiograms based on significant changes of clinical status. The patient successfully underwent microsurgical trapping with clips for the dissecting aneurysm and showed neurological improvement.

Nontraumatic, incracranial giant aneurysm has rarely been reported as the cause of the spontaneous subarachnoid hemorrhage in childhood. Multiple, dissecting giant aneurysms on the left middle cerebral artery with sudden onset of headache in a 14-year-old girl were successfully clipped and followed by complete relief of symptoms. The rarity and characteristics of such lesion in childhood and its successful surgical treatment are discussed briefly.

A 58-year-old woman was admitted to our department due to headache. Brain computed tomography [CT] indicated subarachnoid hemorrhage [SAH], and emergency angiography showed dissecting aneurysm involving the left A1 segment We performed trapping of dissecting A1 aneurysm and the postoperative course was uneventful. We present a case of dissecting aneurysm in the anterior cerebral artery with spontaneous SAH which was treated by early surgery and resulted in clinically good prognosis.

Dissecting aneurysms frequently involve the vertebral arteries and their branches, but those involving the posterior inferior cerebellar artery [PICA] and not vertebral artery at all are extremely rare. We present a case of an isolated dissecting aneurysm of the PICA without involvement of vertebral artery. A 54-year-old man presented with dizziness and headache. MR imaging of the brain showed a cerebellar infarction of the left PICA territory. MR angiographic and cerebral angiographic studies revealed a dissecting fusiform aneurysm involving the left proximal PICA. Subsequently, the patient underwent GDC embolization. A postembolization angiogram demonstrated complete obliteration of the aneurysm. In this report, the treatment modalities for this rare condition is described with review of the literature.

Two cases of the posterior fossa dissecting aneurysm associated with a double origin of the posterior inferior cerebellar artery (DOPICA) causing subarachnoid hemorrhage are presented. After observing a relationship between the aneurysm and DOPICA on a three dimensional rotational angiogram (3DRA), the dissecting aneurysms were successfully obliterated by surgical trapping and endovascular internal trapping, respectively. This report warrants suspecting DOPICA of an associating anomaly predisposing to dissecting aneurysm in the vertebral artery-posterior inferior cerebellar artery territory and highlights the role of 3DRA in pretreatment evaluation of unusual aneurysms accompanying a particular anatomical variation.

Dissecting aortic aneurysm is a disease which is characterized by hemorrhagic intramural seperation of aortic wall and extension for varlng distances proximally, distally, or both from the site of the intimal tear. Most aortas show some type of medial degeneration most commonly described as cystic medial necrosis. DeBackey classified this disease according to involved aorta and site of intimal tear to 3 basic types, such as type I, II and III. Type III is defined that dissecting process arrises in the descending thoracic aorta just distal to origin of the left subclavian artery and extends distally for a varing distance. We expirienced a case of dissecting aneurysm, type III of DeBackey's classification which dissecting process is limited to the descending thoracic aorta in the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. This patient was 40 year old woman and she had suffered from intermittent sharp back pain for 3 years .before admission. Excision of the aneurysm and Dacron graft were placed successfully under the left atrio-femoral bypass with artificial pump. The hospital course was uneventful.

We have experienced 25 cases of aortic aneurysm from October 1987 to January 1996. Patients ranged in age from 26yrs to 73yrs(mean age 52. Syrs). There were 13 males and 12 females. Eighteen cases were thoracic aneurysm and seven were abdom nal aneurysm. The cause of aneurysm were dissecting in 16cases aneurysms and non-dissecting in 9 cases. Risk factors of aortic aneurysm were hypertension, hypercholesterolemia, Marfan's syndrome. In thoracic aneurysm patients, 1'S cases of dissecting aneurysm underwent aneurysmectomy and replacement of vessel interposition graft with or without coronary artery implantation on the graft. 6 cases of non-dissecting aneurysm underwent operation with same policy as dissecting aneurysm. In 7 case of abdominal aneurysm,all patients underwent aneurysmectomy and graft interposition with straight i)r Y graft. Thcre were 5 postoperative death(mortality 20%). Several cases of complications were improved with proper managements. All survivors showed improvement in clinical symptom and sign and discharged without specific complications.
