Aneurysms arising at locations other than arterial division are rare and the incidence of intraoperative bleeding is far higher in such aneurysms than in usual aneurysms. The authors report a case of intraoperative rupture and laceration on internal carotid artery(ICA) wall during dissecting a dorsal wall aneurysm on supraclinoid ICA and successful repair of the laceration on the parent ICA with microsuture and a Sundt clip-graft.

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.

Purpose: Owing to improvement of microscope, microsurgery implements, and microsuture, finger replantation has shown much development. With high success rate of microsurgery in children, positive results have been reported ever from distal amputation. Here, we report the patients demographics, methods, and results of the microsurgery performed in children in our hospital for the last 8 years. Methods: From the medical records of 21 patients who had given the treatment in our hospital from January 2000 to December 2007, we analyzed patients' sex, age, operative method, and complication retrospectively. Results: The number of male patients was twice as many as female, where most patients belong to the ages of five to ten years. Operative methods performed in this study included end - to - end anastomosis of artery and vein, vein graft, and epineurial suture. As a result, 19 out of 21 cases were successfully accomplished, and four of them went through the debridement of necrotic tissue due to the partial necrosis of the lesion. A one - year follow - up observation was done after surgery and most of them were almost fully recovered like in their previous state. Conclusion: The success rate of finger replantaion in children is continuously improving despite the difficulty of vessel anastomotic procedure, rehabilitation treatment and management after surgery. We report the satisfactory results of pediatric finger replantation technically and aesthetically.

Purpose: Microsuturing is a difficult job for beginners of microsurgery. It is because they are not familiar with microscopic environment and, it needs much time for them to get used to microanastomosis. Before the real microsurgery, sometimes a surgeon wants rehearsal. But, microsurgical exercise has been performed with surgical glove, silastic drain or rat femoral artery. Rat femoral artery is a very good training material. But, it needs animal laboratory, anesthesia and its keeping facilities. And the surgeon should appoint the time to exercise with the laboratory. Methods: We used chicken wing brachial artery for education material of microsuturing. The artery is 5 cm long and the diameter is about 1 mm. Monofilament 10-0 was used for suture material. Results: Six persons of Seoul National University medical school students and one resident attended in this program. Each of them performed arterial anastomosis ten times. They were satisfied with chicken wing brachial artery for anastomosis training under the magnification environment. Conclusion: We think that chicken wing brachial artery is a very cheap and an effective training material for the beginners of microsurgery.
