Purpose: The wound of a patient who has chronic venous insufficiency is easy to recur. Also they develop a complication even after the conservative therapy or skin graft. We have to diagnose the venous stasis ulcer correctly and remove the cause to improve the effectiveness of treatment. We operated endoscopic perforating vein ligation and splitt thickness skin graft on a patient with venous stasis ulceration on right leg. Methods: A 26 year old male patient who had a scalding burn on his right leg in July 2005 checked into our hospital in March 2008. Even though he got three operations - the split thickness skin graft - at different clinics, the wound did not heal. The size of the wound was 12 by $8cm^2$ and granulation with edema and fibrosis had been formed. We kept observation on many collateral vessels and perforating vein through venogram and doppler sonography and firmly get to know that the wound came with chronic venous insufficiency. After a debridement and an application of VAC$^{(R)}$ for two weeks, the condition of granulation got better. So we proceeded with the operation using subfascial endoscopic perforating surgery and split thickness skin graft. Results: Through the venogram after the operation, we found out that the collateral vessels had been reduced compared to the previous condition and the widened perforating vein disappeared. During a follow up of 6 months, the patient did not develop recurrent stasis ulcer and postoperative complications. Conclusion: Subfascial endoscopic perforator ligation is relatively simple technique with a low complication rate and recurrence rate. Split thickness skin graft with subfascial endoscopic perforator surgery can be valuable method for treating severe venous stasis ulcers.

Use of the left internal thoracic artery(ITA) to bypass the left anterior descending(LAD) coronary artery has become the standard of care based on its superior graft patency, reduced cardiac events, and enhanced survival. But rarely we encountered with injury to the artery during harvesting which leads to loss of the merits of surgery. We reconstructed inadequate ITAa with other arterial conduits so proximal stump to be a blood source if possible. Maternal and method: Between January 1996 and March 1999, 12 patients received bypass with the reconstructed left internal thoracic artery grafts to left anterior descending artery because of an injury(n=8), short or small(n=4). Right or left ITA was used to LAD as a free graft(n=2). And the other 10 left ITAs were extended with radial artery(n=6), right ITA(n=3), saphenous vein(n=1). Composite "T" graft was made with other arterial conduits in these extended graft(n=5). Result: There was only one morbidity of minor would problem, and no mortality. The patency of extended graft to LAD was complete in 5 patients who received angiography during the period of 2wks to 2 years postoperative, but one of side branch of "T" graft occluded. All of these patients were well. Conclusion: Reconstructive extension with the use of other arterial conduit for the injured proximal ITA is warranted in any patients with acceptable results. acceptable results.

Purpose: An aneurysm is defined as a permanent, localized dilation of an artery with a 50% increase in diameter over its expected normal diameter. Aneurysms can be classified by cause as traumatic and nontraumatic. Traumatic aneurysms can be divided into true and false aneurysms. Nontraumatic causes of peripheral artery aneurysms include mycotic, atherosclerotic, inflammatory, and idiopathic. In the hand, true aneurysms occurring at the common digital artery have been rarely reported. We present a rare case of a true aneurysm of the common digital artery that was resected and reconstructed using a reversed vein graft. Methods: A 49-year-old male patient was refered to our institution with a $0.73{\times}0.44{\times}1.37cm$ sized pulsating mass between 2nd and 3rd flexor digitorum tendons on Lt. palm area. The mass had been present for 5 years and had increased in size over the previous year. No history of trauma was reported. After a physical examination and ultrasound sonography review, a diagnosis of aneurismal dilatation of common digital artery was made. Surgical treatment by excision of the aneurysm, and a reversed vein graft was performed. Results: Histologic examination of the specimen ($3.4{\times}0.7cm$) showed aneurismal dilatation, with elastin fibers present in the arterial wall. The lesions were healed without any complications and there were no evidence of recurrence. Doppler examination of the reconstruction showed good perfusion. Conclusion: Early excision is recommended to relieve symptoms and avoid neurologic damage. Also, artery reconstruction can be performed by primary end-to-end anastomosis or the placement of a reversed interposition vein graft. Micro surgical repair was the only possible treatment in this case. The authors believe that the vascular anatomy should always be restored as natural as possible.

The saphenous vein has been the principal conduit for coronary bypass grafting from the beginning, circa 1970. This report briefly traces this history and concomitantly presents one surgeons experience and personal views on use of the vein graft. As such it is not exhaustive but meant to be practical with a modest number of references. The focus is that of providing guidance and perspective which may be at variance with that of others and recognizing that there may be many ways to accomplish the task at hand. Hopefully the surgeon in training/early career may find this instructive on the journey to surgical maturity.

A patient with benign superior vena cava syndrome caused by the thrombus and fibrotic membrane in superior vena cava is described. Surgical treatment of superior vena cava syndrome remains controversial still. After endvenectomy and thrombectomy of superior vena cava, angioplasty with use of Gore-Tex patch and bypass graft using 10mm diameter Dacron vessel graft from left innominate vein to right atrial appendage were performed. The early postoperative course was uneventful with achievement of good decompression. But 12 months later, the symptoms of superior vena cava syndrome were reoccurred.

관상동맥우회로술 시에 이식편으로 사용되는 혈관들의 조합은 다양하다. 또한 수술 후의 장기 추적조사에 침습적인 관상동맥조영술을 이용하는데는 제한이 되어왔다. 본 연구에서는 좌내흉동맥을 좌전하행지에, 나머지의 목표혈관에는 복재정맥편을 사용하는 고전적인 방법으로 수술한 환자들에서 외래에서 비침습적인 MDCT로 이식편의 개존유무를 수술자의 입장에서 확인하는 방법의 유용성을 평가하고자 하였다. 대상 및 방법: 아주대학교의료원 흉부외과에서 1995년부터 2003년 사이에 다중관상동맥질환으로 관상동맥우회로술을 받았던 환자들 중 외래추적조사에서 특별한 증세의 재발을 호소하지 않았던 환자들을 대상으로 환자의 동의 하에 16 Channel MDCT를 시행하였던 80명의 환자들을 대상으로 이식도관의 개존성을 분석하였다. 결과: 대상환자 중 남녀비는 61:19였으며 평균연령은 $58.9\pm8.9$세였다. MDCT의 촬영시점은 최소 수술 후 7일에서 수술 후 9년으로 중앙값은 6.5년이었다. 환자당 평균 $3.10\pm1.9$개의 도관이 이식되었다. 좌전하행지에 좌내흉동맥을 72명의 환자에 이식하였고, 나머지의 목표혈관에는 복재정맥편을 이식하였다. 복재정맥편의 목표혈관은 좌전하행지 8예, 우관상동맥에 47예, 둔각지에 61예, 대각지에 60예를 각각 이식하였으며, 이중 42예에서 연속문합을 시행하였다. 이식편의 5년개존율이 좌내흉동맥이 $93.1\%$였고 복재정맥괸이 $89.3\%$였다 복재정맥편의 목표혈관별 5년개존율은 대각지 $94.9\%$, 둔각지$92.1\%$, 그리고 우관상동맥이 $79.2\%$순이었다. 복재정맥편의 경우 단독문합의 페쇄율이 $5\~21.3\%$로 연속문합의 $4.8\%$에 비해 높았다. 걸론: 관상동맥우회로 술 후에 외래추적기간 중 시행한 MDCT는 이식도관의 개존을 확인하는데 효과적이었으며, 향후 영상의 해상도가 높아지면 관상동맥의 질환을 진단하는데도 크게 기여할 것으로 기대된다. 본 조사의 결과에 의하면 관상동맥우회로술시에 좌내흉동맥과 복재정맥편을 혼용한 수술의 결과는 만족한 것으로 판단된다.

Brachial artery aneurysms are rare diseases that may be caused by infection or trauma. We report a case of a 71-year-old man who presented with a mass in his right antecubital fossa that increased in size slowly over time. Three years ago, the patient underwent ascending and total-arch replacement with artificial vessel graft to treat aortic root and ascending aorta aneurysm. Preoperative physical examination of right upper extremity showed a nonpulsatile mass with normal pulse of axillary, brachial, and radial arteries. The mass was removed and brachial artery reconstruction was done initially using saphenous vein graft. Two months later, the patient revisited with recurrent pseudoaneurysm, involving the bifurcation point of brachial artery. Aneurysm was totally resected and the brachial artery was reconstructed by interposition graft using a bifurcated GORE-TEX artificial vessel graft. The patient healed without complication and no recurrence was observed. Artificial vessel graft is an available option for reconstruction, and revascularization of vessel defect after excision of brachial artery aneurysm may involve bifurcation point.

Two patients with chronic Budd-Chiari syndrome resulting from segmental obstruction of the inferior vena cava underwent operation. There were 1 man and 1 woman. The obstructed segment was directly visualized by a transthoracic, transdiaphragmatic, retroperitoneal approach. In these two cases, severe segmental obstruction of the inferior vena cava was observed just above the right hepatic vein. These patients underwent successful retrohepatic cavoatrial bypass with a polytetrafloroethylene [PTFE] graft [ 16mm plain and 16mm ringed graft ]. There were no operative mortality and postoperative complication. These patients have been followed up for 6months and 36months without evidence of re-obstruction. When there is a severe stricture of the IVC with hepatic veins draining freely into the obstructed segment of the IVC, a dorsal cavoatrial bypass with a PTFE graft, preferably ringed, is the method of choice.

활액 막육종은 발생 빈도가 낮은 악성종양이며 주로 청소년 연령군에 호발한다. 이 종양은 주로 사지의 관절주위의 연부조직에 발생하며,사지의 주요 혈관을 침범하거나 인접하여 발생하는 경우가 있다. 종래에는 이런 환자들에서 사지 절단술이 자주 시행되 었으나, 최근에는 침윤된 주요혈관들을 종괴와 함께 광범위하게 절제하고 혈관 재건술을 하여 사지 기능 보존을 도모하고 있다. 이와같은 사지의 악성종양 환자에서 사지보존수술을 시행할 수 있는것은 최근의 항암요법 발전에 힘 입은바가 크다. 저자들은 우측대 퇴 정맥에 활액 막육종이 침윤한 35세의 남자에서 종괴를 침윤된 혈관과 합께 제거하고, 복재정맥을 이용한 재건술을 시행하여 양호한 결과를 얻었기 에 보고하는 바이다.

Cutaneous squamous cell carcinoma (CSCC) overlying an arteriovenous fistula (AVF) is rare and presents unique challenges. This case report describes a method of fistula preservation after CSCC excision using a flow-through venous free flap. The saphenous vein of the venous flap was used as flow-through segment for AVF preservation. The flap was inserted along the dorsal aspect of the forearm wound and microvascular anastomosis of the arterial inflow was completed using a vein just proximal to the radiocephalic fistula anastomosis. Venous outflow was established by creating an end-to-end vascular anastomosis between the cephalic vein and the greater saphenous vein. A separate subcutaneous vein was used to provide a low-pressure outflow for the flap to avoid congestion. This case demonstrates an option for AVF preservation that has not been previously described. It also highlights the importance of a multidisciplinary approach for the safe treatment of CSCCs overlying AVFs.
