The anterior communicating artery is one of common sites of intracranial aneurysms, and the anterior communicating artery aneurysms are operated by pterional approach most commonly. Anatomical variation around anterior communicating artery is one of the limiting factors in surgery. Pterional approach can be made from either left or right side according to many factors, such as, dominant feeding artery, shape, size and direction of aneurysm, vascular anomaly and variation around anterior communicating artery, existence of hematoma, and multiple aneurysms. Authors analyzed 62 cases of anterior communicating artery aneurysm and discussed optimal surgical direction in pterional approach and evaluated the usefulness of position of bilateral A1-A2 junction in lateral compression angiogram. The results were as follows: 1) In the existence of another aneurysm in the carotid or middle cerebral artery, optimal surgical direction is to the side of another aneurysm. 2) Significant amount of hematoma should be considered in selecting the surgical direction. 3) If the aneurysm is large, thrombosed, and fundus is broad, the approach should be made to the side which facilitate the exposure of the neck of aneurysm first. 4) Right side approach has advantages that nondominant hemisphere is retracted and surgical manipulation is convenient with small craniotomy. 5) Exposure of the neck of the aneurysm and temporary clip is easier when approach is made along the main feeding artery. 6) Approach to the side of posteriorly placed A1-A2 junction can be another useful option in selecting optimal surgical direction.

PURPOSE: Knee IVIR images were repeatedly obtained after intravenous administration of gadopentetate dimeglumine to evaluate the arthrographic effect and to determine the optimal scan timing and technique. MATERIALS AND METHODS: Sagittal Tl-weighted (650/15) sequences were repeated before and after intravenous gadolinium enhancement in 26 patients who were divided into exercise (14/26) and nonexercise (12/26) groups. Fourteen patients in exercise group were allowed to move the affected knee joint actively for 10 minutes immediately after the first post-enhancement scan and before repeating scans. The signal intensities in central and peripheral portions of the joint were measured and compared between these two groups. RESULTS: In all cases, enhancement of joint fluid began at peripheral portion and progressed toward central portion. The diffusion rate in exercise group was far faster than that in nonexercise group and homogeneous arthrographic image was revealed within 10 minutes after completion of joint movement. The arthrographic effect continued and the rate of signal decrease was quite slow. CONCLUSION: MR arthrographic image of knee joint can be obtained within 10 minutes after completion of a few minute exercise following intravenous injection of gadopentetate dimeglumine. Intravenous MR arthrography is expected to become an useful method as a convenient alternative to direct MR arthrography.

Peripheral nerve injury is relatively common in post-trauma surgery. Although various microsurgical techniques and repair methods can recover the continuity of the injurcd nerve. But, functional recovery achive is difficult. The purpose of this study examines the effect of electrical stimulation on muscle strength or sensibility increase in hrachial plexus injury with clinical results. We have retrospectively analyzed 44 cases of brachial plexus injury. The group(20 cases) which received nerve surgery and electrical stimulation was compared with the group(24 cases) which received nerve surgery only. Electrical stimulation was performed to nerve for axonal regeneration-strength & sensibility(18 cases) and to muscle for strengh(2 cases). All cases had heen evaluated for motor power recovery by 24 months after nerve surgery. A significant difference(P<0.05) between the power of elhow flexion and shoulder abduction, hut not sensibility of forearm in the two groups suggests that electrical stimulation to nerve or muscle enhanced the progress of nerve regeneration or muscle strength respectively. The results suggest that electricai stimulation is promising supplementary method for functional recovery in brachial plexus injury.
