A patient was admitted to our hospital and scheduled to receive left knee arthroplasty and right knee arthroscopic debridement under epidural anesthesia. After anesthesia and surgery, the patient developed below T12 sensory perception lost, urinary retention and fecal incontinence. Magnetic resonance examination was conducted. Spinal hematoma, injury and other epidural anesthesia related complications were excluded. Spinal dural arteriovenous fistula (SDAVF) was diagnosed and removed under indocyanine green staining. Indocyanine green staining is a simple and accurate method for the differential diagnosis of spinal dural arteriovenous fistula with spinal complications. It can also be used to judge the accurate location of arteriovenous fistula and evaluate the effect of arteriovenous fistula resection.

Renal arteriovenous fistula (RAVF) is a rare vascular disease and is usually presented with severe hypertension. Renin-angiotensin-aldosterone system (RAAS) activation was proposed to play a key role in RAVF-induced hypertension but the data was inconsistent. We reported a case of RAVF presented as malignant hypertension, which was detected by contrast-enhanced ultrasonography and successfully managed by interventional embolization. A 35-year-old male was presented with a headache and blurred vision. His blood pressure was up to 220/110 mmHg, with significantly elevated serum creatinine and proteinuria. Hypertensive target organ impairments were noted. A RAVF was detected by contrast-enhanced renal ultrasonography. He underwent renal artery angiography and renal arteriovenous fistula embolization. RAAS activation was also evaluated by separate renal vein sampling. The patient's blood pressure and target-organ damage improved after RAVF embolization and blood pressure control. This is a rare case of renal arteriovenous fistula with malignant hypertension. Contrast-enhanced ultrasonography can be useful for diagnosis.

Post-traumatic arteriovenous fistulae (AVF) can lead to congestive heart failure and limb ischaemia. The objective of this study was to determine the presentations, interventions, and outcomes (morbidity and mortality) of the patients treated with traumatic AVF at a university hospital between January 1995 to December 2018. Nine patients (M: F 8:1) with median age of 30 [IQR 24.5] years were included in the study. They presented as 'missed injuries' with median delay of 4 [IQR 55.25] months. Most had penetrating injuries and presented with painful limb swelling, pain, and venous ulcer. Superficial femoral and popliteal were the most involved vessels. Seven (77.7%) patients had surgery, while 2 (22.2%) had endovascular interventions. Open arterial reconstruction was performed with interposition vein in 4 (44.4%) or with prosthetic grafts in 1(11.1%) patient. There was no peri-operative morbidity or 30-day mortality. All patients had smooth recovery with limb salvage rate of 100%.

INTRODUCTION
Spinal perimedullary arteriovenous fistula (PMAVFS) is a rare intradural vascular malformation with a high rate of misdiagnosis. In adults, most spinal PMAVFs are small and low-flow, starting with progressive spinal dysfunction.
PATIENT CONCERNS
The patient was a 58-year-old male who presented with both lower limbs numb with intermittent walking weakness, obvious at both ankles, and no obvious inducing and relieving factors. The local hospital considered the diagnosis of lumbar disc herniation after MR examination; he was treated with lumbar fixation and fusion.
DIAGNOSIS
After admission, a ce-MRA examination showed that the left spinal artery at the T10 level showed small branch blood vessels in the local area. The distal end was unclear, which seemed to be connected with the drainage vein of the spinal cord. The digital subtraction angiography (DSA) result indicated that the left intercostal artery of T10 sent the Adamkiewicz artery down to the level of L4, and an arteriovenous fistula was seen. The fistula was located at the lower edge of the L4 level and then drained to the upper premedullary vein to the level of T4 after a short descending. It was finally diagnosed as a perimedullary arteriovenous fistula.
INTERVENTIONS
It was cured by cutting the arteriovenous fistula in the spinal canal by indocyanine green-assisted angiography.
OUTCOMES
we report a case of PMAVFS misdiagnosed as lumbar disc herniation with resection and internal fixation. In our hospital, the final diagnosis was a perimedullary arteriovenous fistula, which was cured by cutting off the arteriovenous fistula within the spinal canthus.
CONCLUSION
Spinal perimedullary arteriovenous fistula (PMAVFS) is a rare intradural vascular malformation with a high rate of misdiagnosis. In adults, most spinal PMAVFs are small and low-flow, starting with progressive spinal dysfunction. It is hoped that this can provide warnings to more neurosurgeons and reduce the occurrence of misdiagnosis.

A 46 years old female, with chronic stage renal failure for 15 years, presents to the emergency room with a thrombosis of her brachiocephalic arteriovenous fistula (functional for 13 years). The cephalic vein was aneurismal (6cm diameter) and the brachial artery was not dilated. After proximal and distal control of the brachial artery and the proximal cephalic vein, the aneurismal arteriovenous fistula was excise, the cephalic vein was ligatured, and the brachial artery was repaired with an end to end anastomosis.

BACKGROUND This report presents a rare case of a traumatic innominate artery to left innominate vein fistula following a stab wound to the base of the neck. CASE REPORT We report a case of a 23-year-old patient with a traumatic innominate-innominate arteriovenous fistula, after being stabbed in the suprasternal notch area 3 years prior. The patient presented with fatigue, and shortness of breath on exertion. Examination revealed a wide pulse pressure, bounding pulses, and a continuous murmur on the upper sternal area. Chest X-rays, echocardiography, CT angiography, and cardiac catheterization were useful to aid in diagnosis and work-up for fistula repair. A complex 8-mm fistula between the left innominate vein and the proximal innominate artery was noted, with multiple tortuous channels and demonstrating a reversible left-to-right shunt. After medical optimization, successful surgical ligation and division of the fistula was done through median sternotomy without cardiopulmonary bypass. The postoperative recovery was uneventful. CONCLUSIONS Traumatic innominate-innominate arteriovenous fistulas are rare and can pose a diagnostic challenge. High index of suspicion, careful history, examination, and radiologic evaluation usually result in correct diagnosis. Endovascular and surgical approaches are the mainstay treatment.
