The number of patients with chronic renal failure who require renal replacement therapy is increasing and dialysis is still the mainly used renal replacement therapy. The first choice of surgical technique currently used is side-to-end anastomosis of the radial artery and the cephalic vein. The authors report on a case of an effective arteriovenous shunt operation performed using microscopy. A 53-year-old male with chronic renal failure was referred to plastic and reconstructive surgery department to undergo an arteriovenous shunt operation. Venography was performed before surgery in order to find the appropriate vessel for the arteriovenous shunt operation. The cephalic vein on the wrist showed a diameter of over 4 mm, which was appropriate for an arteriovenous shunt operation. Anastomosis of the vessels was performed under microscopy using Nylon #9-0. Blood flow and vessel diameter were evaluated by venography after surgery and showed well maintained function of the shunt. Complications such as bleeding, edema of the upper arm, and wound dehiscence did not occur. Many factors and certain complications may affect the long-term patency of an arteriovenous shunt; however, exquisite surgical technique is the most important factor in a successful operation. Thus, arteriovenous shunt operation using microscopy is thought to be a good treatment option.

우리는 만성 신부전 환자에서 혈액투석을 위한 상완동맥-두정맥단락술(brachiocephalic arteriovenous shunt)을 시행한 후 최근 빠르게 성장하는 아주 거대한 정맥의 동맥류 1예를 경험하였기에 보고하는 바이다. 환자는 48세 남자로 7년 전 본원에서 동정맥단락술을 시행한 후 혈액투석을 해왔으나 좌측 상완의 정맥을 따라 점점 성장하는 정맥의 동맥류와 박동성 통증으로 혈액투석을 지속할 수 없었다. 내원 1개월 전 혈액투석을 지속하기 위해 타 의료기관에서 우측 손목관절부에 새로운 동정맥루를 조성하여 혈액 투석을 하고 있었다. 동정맥류가 너무 거대하여 동정맥단락 재건술은 시도하지 않았으며 수술은 전신마취하에서 동정맥루를 결찰하고 확장된 정맥의 동맥류를 모두 제거하였다. 환자의 술 후 경과는 양호하였다.

Since January 1973 we have performed 47 arteriovenous shunts and 22 arteriovenous fistulas for 57 patients with acute or chronic renal failure. Of these 57 cases, 50 cases had chronic renal failure and the other 7 cases had acute renal failure. The most frequent complications after operations were thrombosis, bleeding and infection. Less frequently dislodgement of shunt and aneurysmal change of the fistula were found. After 47 arteriovenous shunts, 21 those complications [44%] were found. On the other hand after 22 arteriovenous fistulas, 5 complications were found. Now we are using the arteriovenous shunt only for the patients who need emergency short term hemodialysis and temporary dialysis until arteriovenous fistula could be used.

Pulmonary arteriovenous fistula (PAVF) is a complication of the Glenn shunt. A 57-year-old tetralogy of Fallot (TOF) patient, who had undergone a Glenn shunt and TOF total correction, complained of dyspnea and cyanosis. PAVFs were present in the rig ht lung, and rig ht lung perfusion was nearly absent. After coil embolization, takedown of the Glenn shunt, and reconstruction of the rig ht pulmonary artery, the patient's symptoms were relieved. Extrapulmonary radioisotope uptake caused by the PAVFs shown in lung perfusion scans decreased, and right lung perfusion increased gradually. Although the development and resolution of PAVFs after a Glenn shunt have been reported in the pediatric population, this may be the first report on this change in old age.

The fact there are increase of intrapulmonary arterioveneous shunt amount in the liver cirrhosis patient has been known since 1950. And the method of shunt amount calculation by radionuclide method using $^{99m}Tc-MAA$ was introduced in the middle of 1970. We measured intrapulmonary shunt amount by means of perfusion lung scan using $^{99m}Tc-MAA$ in the various type of liver diseases especially in chronic liver diseases and acute liver disease. The results were as followed. 1) The amount of arteriovenous intrapulmonary shunt in the total case of liver disease was $9.3{\pm}3.9%$, and that of in the control group was $4.6{\pm}2.1%$. 2) The amount of arteriovenous intrapulmonary shunt in the chronic liver disease was $10.8{\pm}4.4%$, and that of in the acute liver disease was $7.2{\pm}2.8%$. We observed significant differences between normal control group and liver disease group, and between chronic liver disease group and acute liver disease group in the amount of shunt by the nucleolide method.

양방향 상행대정맥-폐동맥 단락술 후 폰탄 수술의 위험이 큰 2명의 환자에서 청색증의 증가와 운동 능력의 감소를 보여 액와동정맥루 형성술을 시행하였다. 수술 후 두 환자 모두 수술 후 1일째 일반 병실로 전원되었으며, 수술 후 각각 4일, 3일에 퇴원하였다. 두 증례 모두 수술 후 volume loading의 소견은 없었고, 8개월째 추적 관찰 중이며 청색증의 감소와 운동 능력의 향상을 관찰할 수 있었다. 그러나 수술 후 6개월째 시행한 폐관류스캔이나 contrast심초음파 검사에서 폐동정맥루가 아직 충분히 경감되지 않아, 향후 이에 대한 면밀한 추적 관찰이 필요할 것으로 생각한다.

Pulmonary arteriovenous fistula can occur in a variety of clinical situations including liver diseases, infections, metastatic carcinomas, systemic disorders, and after the palliation of congenital heart diseases. A 72-day-old male infant with Tetralogy of Fallot and pulmonary atresia underwent surgical correction without difficulty. However, ventilator weaning in the ICU failed initially because of an unexplained postoperative hypoxemia(FiO2: 0.8, PaO2: 40 mmHg, SaO2: 80∼90%). Postoperative follow-up lung perfusin scan at postoperative 15 days showed right-to-left shunt(33.6%) and ventilator weaning was performed on the 20th day after the operation (FiO2: 0.4, PaO2, 50mmHg, SaO2: 86.9%). Arterial oxygen saturation under room air was 80∼85% at 7 months postoperatively. One and half year follow-up lung perfusion scan showed decreased amount of right-to-left shunt (11.2%). We report a case with a review of the literatures.

The radioisotope study using $^{99m}Tc-macroaggregated$ Albumin is a simple, non-invasive test for the diagnosis of pulmonary arteriovenous fistula(PAVF). It can show the presence. of the right-to-left shunt at the lung level using the dynamic study, and also the shunt fraction can be estimated. Here we presented the results of the radioisotope study on two patients with PAVF. In one patient, the cardiac catheterization was clone and calculated shunt fractions by both method were well matched.

From november, 1985 to May, 1993, 222 arteriovenous fistulae were made in 201 patients with chronic renal failure. Among them, a total of 183 arteriovenous fistulae in 173 patients were reviewed to evaluate the factors influencing patency rate of the vascular access. The results were revealed as follows: There were 102 men and 71 women,aged 10 to 76 years [mean = 45.7 years]. Sixteen patients of them had previous shunts. The procedures included establishment of 214 radiocephalic or brachioocephalic fistulae, 203 side to end, 9 side to side, 2 end to end, 2 autologous saphenous vein grafts, 6 Gore-Tex grafts. There were 28 early shunt failures[12%] due to use of 23 inadequate veins and 5 thrombosis.There were 32 late complications[14%]; 19 thrombosis, 4 aneurysm, 4 venous hypertension, 3 steal syndrome, 2 infections. There were 32 diabetic patients [17 %]. No significant differences in graft patency were noted between diabetic and nondiabetic individuals. There were no significant difference in graft patency between male and female. Overall shunt patency in 183 cases with chronic renal failure was 96% at I month, 95% at 3 months, 93% at I year, 91% at 2 years, 84% at 3 years, 56% at 5years.This Study showed that early postoperative thrombosis and diabetic vasculopathy were most causes of the vascular access failure and suggested that prevention of thrombi and well control of diabetes mellitus were most important to enhance patency rates of the vascular access.
