Hemarthrosis occurring after arthroscopic surgery for lesions of the shoulder joint is a very rare complication that can develop due to an injury to the blood vessels when an anterior portal is formed. This is a complication that rarely develops in patients who are taking antithrombotic drugs or who do not have associated diseases, such as thrombocytopenia. We report a case of hemarthrosis that occurred after performing arthroscopic surgery to repair a rotator cuff tear in a patient with a stenosis in an arteriovenous fistula for hemodialysis in the ipsilateral upper arm.

Background: Arteriovenous fistula formation is not always easy to perform in hemodialysis patients because of poor preservation of veins due to repeated venipuncture and cannulation. We analyzed the patency rate and complications of prosthetic arteriovenous fistulas using the vena comitantes as a venous outflow in the antecubital fossa, which are protected from venipuncture. Material and Method: Between January 2006 and June 2008, 12 patients underwent prosthetic arteriovenous fistula formation using the vena comitantes as a venous outflow. Arterial inflow was via the brachial artery and the graft was placed in a loop fashion. The male-to-female ratio was 7 : 5 and the mean age was $59{\pm}14$ years. Six patients had diabetes mellitus and 10 patients had hypertension. Result: There were no complications, such as a graft infection or bleeding. Five patients showed postoperative stenosis at an average of 3 months. The primary patency rate was 75.0, 65.6, and 52.2% at 3, 6, and 12 months, respectively. All the patients with stenosis were able to continue hemodialysis after intervention therapy. The secondary patency rate was 100% at 12 months. Conclusion: Creation of a prosthetic arteriovenous fistula using uninjured vena comitantes resulted in a good patency rate and this vein may become a substitute for inappropriate superficial veins.

The arteriovenous fistula (AVF), which maintains satisfactory blood flow, is necessary to the patients of end-stage renal disease for the long term hemodialysis. We performed the snuffbox fistula as the first operation for hemodialysis vascular access. This study was performed to investigate the patency rates, complications, risk factors for occlusion of the AVF, and the types of reoperations. Material and Method: We performed 146 snuffbox fistulas from Jun. 1994 to Dec. 2001 The records of the patients except six patients who were lost from follow up were analyzed retrospectively, Mean age and male:female ratio were 52$\pm$15 years (range, 17∼79 years) and 80 : 60 respectively. Diabetes mellitus and hypertension were combined in 47 patients and 101 respectively. Preoperative levels of creatinine and potassium were 9.09$\pm$3.68 mg/dL (range, 2.55∼20.09 mg/dL) and 4.7$\pm$0.9 mmol/L (range, 2.3∼8.1 mmol/L). One hundred thirteen cases of the snuffbox fistulas were done at left side hand and the others at right hand. Result: Mean follow up period of the patients was 41.8$\pm$31.0 months (range, 0.2∼108,8 months). During the follow up period, 35 occlusions of AVF occurred and these AVFs were patent for 9.8$\pm$10.1 months (range, 0.1∼40.4 months). The patency rates of f month, and 1, 2, 3, 5 years were known as 92.8, 80.2, 73.8, 71.3, 69.6% respectively. Right sided snuffbox fistulas (p-value=0.045) and old age (p-value=0.048) were revealed as significant risk factors for occlusion of AVF. The postoperative complications consisted of occlusions of AVF caused by intimal hyperplasia of vein in 24, thrombosis in nine, stenosis of anastomosis site in three, and venous hypertensions in two. After the first operation 37 patients underwent 86 reoperations. Conclusion: The snuffbox fistulas showed acceptable patency rates and low complication rates. The snuffbox fistulas as the first operation for AVF formation can be a good option for the patients with end-stage renal disease.

A 76-year-old woman with a history of chest pain and palpitation, was diagnosed with bilateral coronary to pulmonary artery fistulae with a concomitant saccular aneurysm, which is quite rare. Suture closure of the fistular vessels around the pulmonary artery root, the removal of a saccular aneurysm, and the transpulmonary closure of coronary to pulmonary artery fistulae were performed. The patient was well at 4 months after surgery.

A 60-year-old man with a history of gunshot vascular injury on the right inguinal area, and this happened in the military service 40 years ago, was admitted to our hospital with claudication and dyspnea on exertion. The patient was diagnosed with a chronic traumatic femoral arteriovenous fistula. The patient underwent a successful operation for arteriovenous fistula closure with bovine pericardium and for femoropopliteal bypass with using a right greater saphenous vein graft. The patient is well at 14 months after the operation.

A 40 year-old male patient admitted for dyspnea and edema of the lower extremities. A pulsatile abdominal mass with a bruit was palpable in the right lower quadrant. Four months previously, he had underwent left partial lam-inectomy ($L4{\sim}5$) and discectomy at the L4 level due to disc protrusion, Computed tomography showed an ilio-iliac AV fistula with pseudoaneurysm at the L5 level. Because massive bleeding occurred when the aneurysm was entered, we closed the aneurysm and performed resection and suture of the aorta and both iliac arteries very near the aneurysm. After exclusion of the arterial side, we performed reduction angioplasty at the aneurysm and aorto-biiliac reconstruction with an artifcial graft. Twenty-four months after operation, he is doing well and hasn't had any complications on the follow-up.

Spinal epidural arteriovenous fistulas (SEDAVFs) are rare spinal vascular malformations that are difficult to diagnose and treat. SEDAVFs can be asymptomatic; however, symptoms can arise from the compression of adjacent nerve roots by dilated vein and perimedullary venous reflux, caused by shunting into the epidural venous plexus. A 31-year-old male presented to our institution with a 2-year history of progressively worsening low-back pain, radiating thigh pain, and sensory changes in his lower extremities. MRI and CT angiography demonstrated dilated epidural vascular lesion compressing the nerve root. The SEDAVF was embolized with multiple coils, which alleviated the nerve root compression from the engorged venous varix and improved the patient's radiculopathy. Our experience from this case shows that endovascular coil embolization using the transarterial approach can be an effective treatment for SEDAVF and an alternative to surgical ligations.

Background: Owing to the fact that the average life span has increased and the progress in medical science has been made, the number of patients with chronic renal failure (CRF) who have to take hemodialysis (HD) has been going up gradually. Accordingly, it is considered to be as a significant issue to obtain blood vessels which can be used repetitively and supply enough blood flows. Therefore, there have been various kinds of study on an inosculation rate andfactors influencing it following an arteriovenous fistula (AV fistula) and lots of studies are ongoing for the purpose of escalating the inosculation rate. The authors analyzed the effects of short-term result, age, sex, diabetes and hypertension on arteriovenous inosculations in 134 anatomical snuffbox operated subjects among the patients who have taken an AV fistula at this center. Material and Method: Based on 134 patients who underwent an AV fistula at the department of thoracic surgery of this center from July, 2000 to May, 2004, the difference in arteriovenous inosculation rate was compared and analyzed depending or age (discriminated by 65-year-old), sex and the condition of the presence or absence of diabetes and hypertension. Correlation analyses were conducted for each parameter and statistical tests were performed by using SPSS for windows Release 11.0.1, which were determined to be statistically significant if p value was below 0.05. Result: The total number of operations was 169 including 35 of re-operations. The male/female rate was 70 : 64 (52% : 48%). The average age was $56.3{\pm}12.26$ years and there were 33 (24%) old aged patients above 65-year-old; there were 103 (71%) patients with hypertension and 90 (67%) patients with diabetes. Overall arteriovenous inosculation rate was $93{\pm}2.4%,\;91{\pm}2.7%,\;89{\pm}3.0%$ at 6, 12, 24 months, respectively. The arteriovenous inosculation rate of above 65-year-old patient group was $85{\pm}4.8%,\;80{\pm}5.8%,\;80{\pm}5.8%$ and below 64-year-old patient group's was $85{\pm}4.8%,\;80{\pm}5.8%,\;80{\pm}5.8%$ at given time points, respectively, which showed higher inosculation rate in below 64-year-old patient group with a statistical significance (p=0.0034). However, no statistical significance was found between the patients with hypertension and diabetes and the patients with no complication. In addition, there was no statistical significance in inosculation rate between male and female. Conclusion: The arteriovenous inosculation ratewas higher in the treated patient below 64-year-old than in the treated patient above 65-year-old. Thus it is advantageous for increase in long-term inosculation rate to obtain hemodialysis routes at an early age. The conditions of sex and the presence or absence of diabetes and hyper- tension do not make statistically significant effect on the arteriovenous inosculation rate.

A twenty six year old man was admitted to our clinic for bleeding from a venous ulcer of the left leg. His left femoral vein had been ligated for bleeding control after a traffic accident that happened when he was 5 years old. He had a varicose vein, stasis dermatitis, and a venous ulcer on his left leg. To shunt left femoral venous return to the right femoral vein, we did a crossover bypass with arteriovenous fistula using the right greater saphenous vein. To get good patency of the arteriovenous fistula, the bypass graft was closed 6 weeks after the initial operation. He maintained his left leg circumference relatively well for 6 months after the operation. We report the case of a patient who had a vein crossover bypass for a chronic femoral vein ligation.

Systemic arteriovenous(AV) fistulas are a rare but well-recognized cause of hyperkinetic circulation that, if undetected, may lead to congestive heart failure. We experienced a very rare case of acquired arteriovenous fistula. A 61-year-old female patient presented with congestive heart failure symptoms after percutaneous pinning for right sternoclavicular joint dislocation. We surgically obliterated the fistula between aorta and innominate vein and performed tricuspid annuloplasty for severe tricupid insufficiency simultaneously. She was discharged with complete relief of her symptoms and has been well during 2 years and 6 months follow up.
