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.

If a ruptured blood blister-like aneurysm (BBA) arises from the lateral or superolateral wall of the internal carotid artery (ICA) at the level of the anterior choroidal artery (AChA), its proximity to the origin of the AChA presents a serious surgical challenge to preserve the patency of the AChA. Two such rare cases are presented, along with successful surgical techniques, including the application of a C-shaped aneurysm clip parallel to the ICA and a microsuture technique to repair the arterial defect. The patency of the AChA and ICA was successfully preserved without recurrence or rebleeding of the BBA during a 1-year follow-up after the operation.

Traumatic intracranial aneurysm rarely occurs after a head injury. The authors report a case of a 51-year-old man in whom subarachnoid hemorrhage was developed as a result of delayed traumatic aneurysmal rupture of the distal portion of the middle cerebral artery following a minor, closed-head injury. The unruptured aneurysm had been evident on the magnetic resonance image taken two days prior to onset of the subarachnoid hemorrhage. The clinical presentation and possible underlying mechanism are discussed with a review of pertinent literature.

Pseudocoarctation is extremely rare and is due to elongation and kinking of aortic arch which mimiks true coarctation but has no pressure gradient across it. This state is essentially benign entity and needs no surgical intervention, but it frequently tends to progress into the aortic aneurysm that results in compressive symptom due to mass effect and unawared rupture and death.We experienced a descending aortic aneurysm secondary to pseudocoarctation. The patient was 53 year-old female presented as easy f`atiguability and facial flushing. The aortogram revealed tortuous and enlarged aorta at the level of ligamentum arteriosum. The aneurysm was resected and was end-to-end anastomosed successfully under partial cardiopulmonary bypass. The postoperative course was uneventful and the patient was discharged on postoperative 10 day.

Mycotic aneurysm is a disease requiring immediate treatment because of the high risk of rupture. A difficult surgical approach, especially in the case of occurrence on the iliac artery, involving endovascular embolization and extra-anatomic bypass grafting, is known to be a suitable treatment. We performed extra-anatomic bypass grafting after endovascular embolization successfully in two patients. The postoperative computed tomography of both patients showed complete exclusion of the mycotic aneurysm.

We present a case of ruptured abdominal aortic aneurysm caused by blunt injury. The patient was 23-year-old soldier injured by a motor vehicle accident. Injuries sustained a contused abdominal aorta. At the time of aortic repair, the involved segment formed huge pseudoaneurysm, and which had intimal tear. Aorto-iliac graft replacement was carried out with a woven-dacron Y-graft prosthesis, which restored satisfactory circulation to both lower limbs. The postoperative course was uneventful.

Objective : We evaluate the effect of the copolymer-coated coils on immediate occlusion of the aneurysm, preventing rupture, and decreasing compaction or re-growth. Methods : Thirty-five aneurysms treated between September 2003 and December 2004 using Matrix detachable coil were reviewed. Study population consisted of 12 men and 23 women ranging in age from 34 to 75 years[mean, 55.1 years]. Twenty-two aneurysms were ruptured and 23 aneurysms were located in the anterior circulation. Follow-up angiography was obtained in 16 patients after 6 months from the procedure. Results : Initial complete occlusion was achieved in 17 aneurysms[48.6%], and the others remained as a residual neck in 8 aneurysms[22.8%] and residual sac in 10 aneurysms[28.6%]. Among these incompletely occluded aneurysms, 7 aneurysms were performed follow-up angiography. And 6 of them converted into complete occlusion. In the other hands, among 17 aneurysms achieved complete occlusion initially, 9 aneurysms were performed follow-up angiography. Recurrence due to coil compaction occurred in one aneurysm and the others maintained complete occlusion. There was one mortality case due to thromboembolic complication. Conclusion : In spite of difficulty in achieving complete occlusion with Matrix coil system, there is no rupture or re-rupture during follow-up period. Follow-up angiography shows many conversions of residual sac into complete occlusion. Embolization using Matrix coil system is safe and effective, but the effects of PGLA copolymer need further investigation.

Purpose: In the treatment of aortic aneurysm, endovascular stent-graft application has become an established method of treatment. To observe the outcomes of the procedure as the size change of aneurysm in relation with endoleak, a retrospective analysis was done for the consecutive cases who undertook the procedure. Materials & Method: Stent-graft was applied to the aortic aneurysm in 33 patients. The location of the aneurysm was thoracic in 11 patients and abdominal in 22 patients. CT angiographic was done for the follow-up evaluation to analyze the aneurysm size and the presence of endoleak. Results: Technical success rate was 97% (32/33). The primary success rate without endoleak was 84% (28/33). The secondary success was 90% (30/33). During the follow-up period of 3 months to 7years and 6months in 26 patients, a secondary endoleak developed in 5 cases. Post-implantation syndrome developed in 17 cases (51%). Among the 14 cases with follow-up imaging data for size, endoleak was negative in 10 cases. The aneurysm decreased in 5 cases, stable in size in 4 cases and enlarged in one case (10%).Among the 4 cases with endoleak positive, the aneurysm enlarged in two cases (50%). Conclusion: In the stent-graft application for aortic aneurysm, there is high chance of decrease of aneurysm size in those cases with endoleak negative. However, the aneurysm may increase and eventually rupture in the cases with en do leak positive. Close observation with CT angiography is necessary for the evaluation for the presence of endoleak and size change.

Anterior communicating artery (ACoA) aneurysms sometimes present with visual symptoms when they rupture or directly compress the optic nerve. Giant or large ACoA aneurysms producing bitemporal hemianopsia are extremely rare. Here we present an unusual case of bitemporal hemianopsia caused by a large intracranial aneurysm of the ACoA. A 41-year-old woman was admitted to our neurosurgical department with a sudden-onset bursting headache and visual impairment. On admission, her vision was decreased to finger counting at 30 cm in the left eye and 50 cm in the right eye, and a severe bitemporal hemianopsia was demonstrated on visual field testing. A brain computed tomography scan revealed a subarachnoid hemorrhage at the basal cistern, and conventional cerebral catheter angiography of the left internal carotid artery demonstrated an $18{\times}8mm$ dumbbell-shaped aneurysm at the ACoA. Microscopic aneurysmal clipping was performed. An ACoA aneurysm can produce visual field defects by compressing the optic chiasm or nerves. We emphasize that it is important to diagnose an aneurysm through cerebrovascular study to prevent confusing it with pituitary apoplexy.

Internal carotid artery (ICA) trapping can be used for treating intracranial giant aneurysm, blood blister-like aneurysms and ICA rupture during the surgery. We present a novel ICA trapping technique which can be used with insufficient collaterals flow via anterior communicating artery (AcoA) and posterior communicating artery (PcoA). A patient was admitted with severe headache and the cerebral angiography demonstrated a typical blood blister-like aneurysm at the contralateral side of PcoA. For trapping the aneurysm, the first clip was placed at the ICA just proximal to the aneurysm whereas the distal clip was placed obliquely proximal to the origin of the PcoA to preserve blood flow from the PcoA to the distal ICA. The patient was completely recovered with good collaterals filling to the right ICA territories via AcoA and PcoA. This technique may be an effective treatment option for trapping the aneurysm, especially when the PcoA preservation is mandatory.
