Large scalp defects resulting from high-voltage electrical burns require free flaps, preferably skin, to permit optimal coverage and enable future or simultaneous cranial vault reconstruction. The anterolateral thigh permits the harvest of a large area of skin supplied by a reliable perforator. The superficial temporal vessels offer the proximate choice of recipient vessels to enable adequate reach and coverage. The lack of a second vein at this site implies the inability to perform a second venous anastomosis; however, this obstacle can be overcome by using an interposition vein graft, to the neck veins primarily. This assures adequate venous drainage and complete flap survival.

During the period from Mar. 1983 to Feb. 1986, 22 patients with vascular trauma were treated at Capital Armed General Hospital. 1] 11 patients had arterial injury alone, 6 patients had venous injury alone, and 5 patients had both arterial and venous injuries. 2] The mechanism of injury in these 22 patients was 7 penetrating non-gun shot wounds, 5 blast fragments injuries, 4 iatrogenic injuries, 4 blunt injuries, 2 gun shot wounds. 3] The method of 16 arterial repair was 5 autogenous saphenous vein graft, 8 synthetic vascular graft, 1 end to end anastomosis, 2 lateral suture. Midterm patency of 16 repairs was 100% within 1 months. 4] The method of 11 venous repair was 1 autogenous saphenous vein graft, 2 onlay vein patch, 2 ligation, 1 lateral suture. The thrombotic obstructions occurred in 4 repairs [36.4%], but they were resolved somewhat with heparinization. 5] Uncommon cases of false aneurysm of internal carotid artery and laceration of retrohepatic inferior vena cava were summarized.

We report a case of 44 years old male patient with neuroma-in-continuity of ulna nerve. In the patient's past history, he had received operative treatment for the open supracondylar fracture of right distal humerus and ulnar nerve injury at 10 years ago, and neurolysis was tried 2 times due to severe neuropathic pain. Despite of these operations, the symptom was not improved. In operative field, we noticed neuroma-in-continuity and decided to resect the neuroma until normal nerve fascicle was noted. The nerve cable graft was done with auto sural nerve on the defect site and the nerve was wrapped with small saphenous vein. At post operative 7 months, pain was markedly decreased and sensory recovery was slightly improved and patient was satisfied with the result.

배경: 관상동맥에 내흉동맥편과 복재정맥편을 동시에 문합할 때 두 이식편 사이에 생기는 혈압과 혈류의 차이 때문에 내경이 작은 내흉동맥편의 개존이 나빠질 수 있다. 이런 수술을 받은 환자에서 중단기적 임상 결과를 보고 특히 상경적인 혈류의 영향을 많이 받는 내흉동맥편의 개존 상태를 알고자 하였다. 대상 및 방법: 좌전하행지에 문합된 내흉동맥의 혈류가 충분하지 못하다고 판단된 14예의 환자에서 같은 관상동맥에 좌내흉동맥편과 복재정맥편을 동시에 문합하였다. 평균 33.5개월의 추적기간동안 증상이 재발한 경우, 좌내 흉동맥편의 혈류를 확인하고자 하는 경우, 수술 직후에 Q파를 보인 경우 등 6예에서 관상동맥 조영술을 시 행하였다. 결과: 복재정맥편과 내흉동맥편은 모두 개존되어 있었으며, 2예에서는 양측 균등한 혈류를 보인 반면, 다른 2예에서는 상경적인 혈류를 보였고 나머지 2예에서는 내흉동맥편이 개존되어 있었으나 관상동맥 으로 가는 혈류는 거의 없었다. 결론: 좌내흉동맥편을 좌전하행지에 문합하는 수술에서 복재정맥편을 부가 적으로 좌전하행지에 문합하는 경우에 수술 후 좌전하행지의 혈류를 충분히 유지할 수 있으며, 이러한 이중 문합이 내흉동맥편의 중단기적 개존에 영향을 미치지는 않을 것으로 생각된다.

배경: 하지동맥의 협착성 질환에서 슬와동맥 및 그 이하 분지들의 협착이 있을 경우 인조혈관과 슬와 동맥 사이의 크기 불일치가 발생하여 원위부 문합이 곤란하게 된다. 본원에서는 자가 대복재정맥 정위 이식편을 이용하여 하지동맥의 혈류를 복원하고자 하였다. 대상 및 방법: 2000년 7월부터 2005년 7월까지 총 26명의 환자에서 대복재정맥 정위 이식편을 이용한 수술을 시행하였으며, 임상 결과들을 환자의 차트 기록에 근거하여 후향적으로 분석하였다. 결과: 술 후 원내 사망이나 조기 사망은 없었으며, 추적기간 동안 총 6명의 만기 사망이 발생하였다. 수술 도중 및 술 후 합병증으로는 5예의 조기 이식편 폐쇄, 2예의 창상 열개, 1예의 이식편 내 동맥류 형성, 1예의 서혜부 창상 장액종 형성, 1예의 이식편 손상이 발생하였으며, 추적기간 동안 이식편 개통률은 69.3%였다. 결론: 대복재정맥 정위 이식편은 슬와동맥 및 그 이하 분지의 협착을 동반한 하지동맥 폐쇄성 질환에서 유용한 혈관 이식편으로 생각된다.

The purpose of this study is to investigate if there is a higher rate of free flap failure in cases of vein grafts compared to non-vein graft, and to analyze the clinical usefulness and necessity in elective free flap surgery. We have used 24 vein grafts in 208 free flaps from May, 1986 until August, 1995. Vein grafts were from 2cm to 50cm in length between the recipient and donor vessels. Reconstructed sites were 10 lower extremities, 8 head and neck, 4 hand, and 2 trunk. Vein grafts were used 14 for arterial, 6 venous, 4 in both arterial and venous anastomoses. We intentionally used long vein grafts longer than 5cm for improved blood flow in cases of peripheral vascular disease, radionecrotic wounds, lower leg trauma. Short vein grafts of about 3cm in length were used to overcome the shortage of vascular length in cases of unexpected vessel anomaly, short donor vessel, and difficult access to recipient vessels after radical neck dissection. All veins were carefully handled with ligation of very small branches and were transferred to the recipient site without irrigation. 8 flaps were failed out of a total of 208 free flaps, however there was no failure among the 24 cases that needed vein grafts between the donor and recipient vessels. Success rates between non-vein grafts free flaps and vein graft free flaps were 95.6%(8/184) and 100%(0/24). Even though the vein grafts increase the operation time and the number of anastomoses, they do not result in any increased failure rate of free flap surgery(4.4% versus 0%). In addition to the reducing tension between recipient and donor vessels, the surgeon can select better recipient vessels with excellent blood flow so that vein grfats in microsurgery can provide a high success rate of free flaps.

Reconstruction of the pharynx and cervical esophagus presents a tremendous challenges to surgeons. Over the past 2 years[1990, Dec.-1993, Jun], the free jejunal graft has been performed in 17 cases in Korea Cancer Center Hospital.The indications of this procedures were almost malignant neoplasms involving neck and upper aero-digestive tract; Hypopharyngeal cancer[12 cases, including 2 recurrent cases], laryngeal cancer[2 cases], thyroid cancer[2 cases, including 1 recurrent case], cervical esophageal cancer[1 case]. There were fifteen men and two women, and the mean age was 59.6 years. The anastomosis site of jejunal artery were common carotid artery[16 cases] or external carotid artery[1 case] and that of jejunal vein were internal jegular [15 cases] or facial[1 case] and superior thyroid vein[1 case]. The length of jejunal graft was from 9 cm to 17 cm[mean 13 cm] and the mean ischemic time was 68 minutes. There was one hospital mortality which was irrelevant to procedures[variceal bleeding] and one graft failure[1/16]. Other postoperative complications were neck bleeding or hematoma[3 cases], abdominal wound infection or disruption[5 cases], anastomosis site leakage[1 case], pneumonia[2 cases], graft vein thrombosis[1 case], and food aspiration[1 case]. The function of conduit was excellent and ingestion of food was possible in nearly all cases. Postoperative adjuvant radiation therapy was also applicable without problem in 7 cases. During follow-up periods, the anastomosis site stenosis developed in four patients, and the tracheal stoma was narrowed in one case but easily overcome with dilation. In conclusion, we think that the free jejunal graft is one of the excellent reconstruction methods of upper digestive tract, especially after radical resection of malignant neoplasm in neck with a high success rate and low mortality and morbidity rate.

혈관 내 재개통 인터벤션은 수술 후 정맥폐색에 있어 효과적인 치료 방법 중 하나이다. 간경유 또는 비장경유를 통한 접근을 흔히 시도하지만, 경피적 장간막 경유 접근 방법은 전향적인 접근이 가능한 장점이 있다. 본 증례는 수술 후 간문맥 이식편 폐색 환자에서 경피적 장간막 경유 접근법으로 성공적인 혈관 내 재개통을 보여준다.
