Since the introduction of percutaneous; transluminal coronary angioplasty[PTCA] by Grunt-zig in 1977, this is widely used in some patients with coronary artery disease and is an effective alternative to surgery for many patients. Indications for emergency coronary artery bypass graft[CABG] after PTCA are prolonged chest pain, worsening of coronary artery obstruction, "current of injury" by electrocardiogram, cardiogenic shock, and in a lesser incidence, ventricular fibrillation, coronary artery dissection[without obstruction], heart block, and intractable cardiac arrest. Recently, we have experienced one case of emergency CABG following unsuccessful PTCA. The patient was 54 year-old male and admitted with complaint of angina pectoris. The routine electrocardiogram revealed within normal limit. The treadmill test revealed severe chest pain after 2 min. exercise. Coronary cineangiogram revealed 95% segmental stenosis of the proximal right coronary artery. Our cardiologist was planned PTCA. During PTCA, severe chest pain and ischemic pattern on electrocardiogram were developed. But they were not relieved even by morphine and nitroglycerin till 90 min. So we performed emergency single coronary artery bypass graft from aorta to proximal right coronary artery with great saphenous vein. The patient had an excellent postoperative recovery and was free from anginal attack. He has shown striking improvement in general status[NYHA functional class 1] during 6 months after operation.operation.

We present a case of a near total amputation at the distal tibial level, in which the patient emphatically wanted to save the leg. The anterior and posterior tibial nerves were intact, indicating a high possibility of sensory recovery after revascularization. The patient had open fractures at the tibia and fibula, but no bone shortening was performed. The posterior tibial vessels were reconstructed with an interposition saphenous vein graft from the contralateral side and a usable anterior tibial artery graft from the undamaged ipsilateral distal portions. The skin and soft tissue defects were covered using a subatmospheric pressure system for demarcating the wound, and a latissimus dorsi myocutaneous free flap for definite coverage of the wound. At 6 months after surgery, the patient was ambulatory without requiring additional procedures. Replantation without bone shortening, with use of vessel grafts and temporary coverage of the wound with subatmospheric pressure dressings before definite coverage, can shorten recovery time.

Purpose: The clinical syndrome of unilateral finger ischemia, caused by digital artery occlusions from embolization from the palmar ulnar artery associated with repetitive striking of the palm, has been called the hypothenar hammer syndrome (HHS). We report the case of a man with this unique disease probably caused by manual work. Methods: A 52 - year - old male left - hand dominant manual worker complained of pain and coldness in the left 4,5th finger. On physical examination, there was a tip necrosis and the result of Allen's test was mildly positive(sluggish filling of hand from the ulnar artery). Arteriograms confirmed occlusion of the distal ulnar artery without direct perfusion of the superficial palmar arch and distal digital artery. Surgical bypass with reverse autologous vein grafting was performed between ulnar artery and superficial palmar arch, common digital artery. Results: He had an uneventful postoperative course and has remained asymptomatic for 18 months since discharge. Patency has been confirmed by color doppler with resolution of cold intolerance and successful digital preservation. Conclusion: We introduce very unique pattern of vascular ischemic disease and recommend the arterial bypass with vein interpositional grafting.

Purpose: Artificial dura maters are commonly used in cranioplasty, but sometimes they can result in serious postoperative infection. Once complications such as epidural abscess or chronic draining ulcer arise, they are very difficult to treat. In this case, reclosure of dura defect using artificial dura mater may give rise to recurrence of infection. We experienced a case of intractable epidural abscess caused by use of artificial dura. To avoid repeated infection, we decided to use autologous tissue for the coverage of dura and soft tissue defect. Therefore, autologous tensor fascia lata graft and anterolateral thigh free flap were harvested at the same donor site incision to cover composite defect on the scalp and dura mater. Methods: A 13 year old male patient, who underwent the decompression cranioplasty and duroplasty, suffered from the intractable infection lesion. Twice, the epidural abscess was removed, both times the infection recurred. And eventually dura mater was exposed through the infected open wound. Nine months after dura exposed, infected aritificial dura mater was removed and extensive debridement was performed. Through a surgical incision on donor thigh, first, tensor fascia lata graft was harvested in process of the anterolateral thigh flap elevation. After the fascia lata graft was fixed over the dural defect, the anterolateral thigh flap was used to fill the dead space as well as the scalp defect. Results: Postoperatively, no recurrent infection and cerebrospinal fluid leakage are observed for a year. After the surgery, on the first and second day, venous congestion of the flap was observed, this problem was solved by thrombectomy and vein reanastomosis. And partial necrosis of flap occurred, but completely healed as conservative treatment for two weeks. Conclusion: Using the autologous tensor fascia lata graft and anterolateral thigh flap, we could obtain satisfactory results as treatment for the intractable infection lesion after duroplasty. Autologous tensor fascia lata in conjunction with anterolateral thigh flap is useful method for covering composite defect of scalp and dura mater.

Purpose: The soft tissue injuries of the patellar area are difficult problems because of insufficient arterial blood supply and lack of muscle layer. There have been many methods for reconstructing the soft tissue injuries of the patellar area such as primary closure, skin graft, local flap and free tissue transfer. However, each method has some limitations in their application. After the first introduction, the fasciocutaneous flaps are widely used to reconstruct the soft tissue injuries. The saphenous nerve, one of the superficial sensory nerves in the lower leg, is supplied by the saphenous artery and its vascular network. We used the saphenous fasciocutaneous island flap to reconstruct the soft tissue injuries of the patellar area. Methods: From March 2002 to May 2005, we used the saphenous fasciocutaneous island flap to reconstruct the soft tissue injuries of the patellar area. The flap was elevated with saphenous nerve, saphenous vein and saphenous artery and its vascular network. The flap donor site was reconstructed with primary closure or split-thickness skin graft. Results: Five cases survived completely but 1 case developed partial necrosis of the skin on the upper margin of the flap. However, the necrosis was localized on skin layer, and we reconstructed with debridement and split-thickness skin graft only. After the operation, there was no contracture or gait disturbance in any patient. Conclusion: In conclusion, the saphenous fasciocutaneous island flap is safe, comfortable and effective method to reconstruct the soft tissue injuries of the patellar area.

Purpose: Prevention of acute rejection in skin allografts without continuous immunosuppression lacks reports in worldwide literature. Needs for chronic immunosuppression preclude the use of tissue allograft as a routine surgical reconstructive option. Recently dendritic cells(DC) gained considerable attention as antigen presenting cells that are also capable of immunologic tolerance induction. This study assesses the effects of alloantigen-pulsed dendritic cells in induction of survival increase in a rat skin allograft model. Methods: Recipient-derived dendritic cells were harvested from rat whole blood and cultured with GM-CSF(200 ng/mL) and IL-4(8 ng/mL) for 2 weeks. Then donor-specific alloantigen pulsed dendritic cells were reinjected into tail vein before skin graft. The rat dorsal skin allografts were transplanted in 5 subgroups. Groups: I) untreated, II) anti-lymphocyte serum(ALS, 0.5 mL), III) FK-506(2 mg/kg), IV) DCp, VI) DCp and FK-506. Graft appearance challenges were assessed postoperatively. Results: The group V(DC and FK-506 treated) showed longest graft survival rate(23.5 days) than other groups; untreated(5.8 days), ALS(7.2 days), FK-506 (17.5 days), DCp(12.2 days). Conclusion: Donor antigen pulsed host dendritic cell combined with short-term immunosuppression prolong skin allograft survival and has potential therapeutic application for induction of donor antigen specific tolerance.

Purpose: Reconstruction of full - thickness defects of the nasal ala has always been a challenge. Local flaps can be used easily, and good result can be achieved when it is indicated. But local flaps often result in facial scars and bulky ala that require secondary revisions. Composite auricular chondrocutaneous graft may matches nasal alae well in terms of contour, color and texture, however, the size of composite graft is limited. We performed free vascularized helical root flaps for reconstruction of nasal ala. Methods: Bilateral ala were excised and the defects were reconstructed with a chondrocutaneous free helical root flap. Each side of ala was reconstructed in 3 months interval. Superficial temporal vessels of vascularized helical root flap were anastomosed to facial vessels. Great saphenous vein was used for interpositional vascular graft. Results: Flaps were survived successfully. The contour, texture and color match were satisfactory. Functional problem of nasal obstruction caused by scar stenosis of nostrils was also resolved. Conclusion: The free vascularized helical root flap is a reliable method in reconstruction of nasal alar defects. The donor deformity was minimal.

Aortic arch syndrome is an unusual disease entity characterized by the narrowing or obliteration of major branches of the arch of the aorta regardless of etiology. We have experienced 2 cases. One of them was 22 years old office girl with 3 months history of headache, intermittent syncope and weakness and claudication on left arm especially during her physical exercise. On physical examination, pulseless on left antecubital and radial artery and blood pressure on left arm was inable to check and coldness with weakness were noted on the same side. Aortic angiography reealed 34% narrowing of left subclavian artery as that of right. But both common carotid artery and both axillary arterial patency were relatively good. Through right supraclavicular and left axillary incision, bypass graft with Gore-tex prosthesis (I.D. 6mm, Length 25 cm) was implanted from right subclavian artery on 2cm distal to origin of right common carotid arery to left axillary artery distal to axillary fossa. End to side anastomosis with preservation of left subclavian artery was done. Postoperative state was stable with blood pressure of 110/70 mmHg on left arm and palpable antecubital and radial pulsation. Another one was 41 year old male patient with 8 months history of pain and numbness on right upper arm and shoulder. On admission, right arm blood pressure was 110/80 mmHg, left arm was 160/110 mmHg, but other physical findings had no abnormalities. Angiography revealed segmental narrowing of right axillary artery on the beginning with 2 cm in length. Operative treatment with right wupraclavicular and right axillary incision, bypass graft with great saphenous vein (Length; 15 cm) from right subclavian artery between scalenus anticus and medius to axillary artery at distal end of axillary fossa was done. The authors report two cases of Aortic arch syndrome treated with bypass graft using Autograft or Gore-tex with good result.

최근 혈관 질환의 진단을 위한 비침습적 영상이 발달하면서, 기존의 도자술은 중재적 치료에 국한되는 실 정이다. 그러나 관상동맥이나 우회로는 작은 직경, 심박동 움직임 등으로 도자술이 아직도 진단에 필수적이 며, 비침 응\ulcorner영상 진단의 마지막 도전 영역이다. 전자선 단층 촬영기는 높은 시간 해상능으로 심장 영상을 얻을 수 있다. 전자선 단층 촬영을 이용하여 모관상 동맥 협착이나 관상동맥 우회로 이식술 후 개존성의 평 가가 시도되고 있으며, 이중 관상동맥 우회로술 평가의 정확도는 매우 높아서 임상 적용이 가능하다. 저자와 다른 연구자의 경험에 의하면 복재 정맥은 넓은 직경, 비교적 짧고 직선적인 경로, 심박동에 덜 영 향 받음으로써 EBT조영술의 정확도가 높았다. 전향적 민감도와 특이도가 각각 92%, 97%를 보였다. 그러나 위양성과 위음성을 보인 두 예는 후향적으로 분석 할 때 경험 부족에 의한 초기의 판독 오류로 사료되어 복 재 정맥의 경우 후향적으로는 100%의 정확도를 보였다. 반면 내유동맥 이식혈관은 작은 내경과 주변의 수술 클립에 의한 인공산물로 개존성을 확인하기가 대체로 어려웠고, 역동적 검사를 병행하여 우회로내 혈류를 확인하는 것이 필요하다. 내유동맥의 경우 상대적으로 정확도가 낮아 민감도, 특이도가 각각 100%, 80%를 보였으며, 위양성을 보인 2예는 후향적으로도 개존을 확인할 수 없었다. 전자선 단층 촬영 혈관 조영술은 관상 동맥 우 막\ulcorner이식술 후의 우회 혈관 개존성의 평가, 특히 복재 정맥 우회로의 경우 매우 정확도가 높은 비침습적 검사로써, 임상 적용이 기대된다. 앞으로 촬영 기기와 영상 재구성 software의 발달로 정확도를 더욱 높일 수 있는 잠재성이 있다.
