Central venous lesion is a difficult problem in the vascular access complications of hemodialysis, which can cause serious clinical symptoms and affect the quality of hemodialysis and life of patients. We established arteriovenous fistula of the contralateral graft blood vessel with the used vein on the diseased side of the central vein of the patient. The arteriovenous fistula of the graft blood vessel was successfully punctured and hemodialysis was performed 2 weeks later. In this way, we not only solved the problem of venous hypertension and subsequent vascular access in the patient, but also reserved more vascular resources.

The three-day-old female infant was admitted to the hospital due to respiratory distress after birth. She was born premature at 36⁺² weeks gestational age. Prenatal ultrasound suggested abnormal development of the fetal liver vessels, and she had dyspnea that required respiratory support after birth. Chest X-ray indicated an enlarged cardiac silhouette, and cardiac ultrasound revealed enlargement of the right atrium and right ventricle. Diagnosis of hepatic hemangioma with arteriovenous fistula was confirmed through liver ultrasound and abdominal enhanced CT. At 19 days old, she underwent ligation of the hepatic artery under general anesthesia, which led to an improvement in cardiac function and she was subsequently discharged. Genetic testing revealed a mutation in the ACVRL1 gene, which was inherited from the mother. The article primarily introduces a case of neonatal heart failure caused by hepatic hemangioma with arteriovenous fistula, and multi-disciplinary diagnosis and treatment of this disease.

A girl, aged 15 years, was admitted due to sudden convulsion once and multiple pulmonary nodules on lung CT. Acrocyanosis or acropachy/toe deformity was not observed. Laboratory examinations showed an increase in hemoglobin (162 g/L) and a reduction in arterial partial pressure of oxygen (61.5 mm Hg). Lung CT showed irregular slightly high-density nodules in the middle lobe of the right lung, and contrast-enhanced CT scan showed obvious enhancement with thick vascular shadow locally. An investigation of medical history revealed that the girl's mother had a history of epistaxis and resection of pulmonary mass and the girl presented with tongue telangiectasia. The girl was diagnosed with hereditary hemorrhagic telangiectasia and pulmonary arteriovenous malformation. she was given interventional embolization therapy. Transcutaneous oxygen saturation reached 98% without oxygen inhalation on the day after surgery. Pulmonary angiography at 3 months after surgery showed the recurrence of pulmonary vascular malformation, and embolization of pulmonary arterial fistula was not performed since the guide wire could not enter the branch artery. There was still a need for long-term follow-up.

Carotid-cavernous fistula (CCF) is a rare and dangerous neurological disorder that arises due to an abnormal communication between the internal carotid artery (ICA) or the external carotid artery (ECA) and their branches and the cavernous sinus. It can either be a direct fistula (high-flow with acute symptoms) most commonly resulting from trauma (70-90%) or an indirect fistula (low-flow with insidious symptoms) secondary to hypertension, atherosclerosis and collagen vascular disorders. The shunting of arterial blood into the venous system leads to venous hypertension causing various clinical manifestations depending on the venous drainage patterns and the shunt flow. Increased anterior, posterior and superior venous drainage results to orbital/ocular, cavernous and cortical symptomatology, respectively. This paper aims to present a case of 58-year old Filipino female with a 2-day history of sudden, severe headache, vomiting and blurring of vision followed by decrease in sensorium and sudden proptosis and chemosis of the left eye. Patient had no co-morbidities, history of trauma, surgeries, facial skin infections or prior febrile illness. The left eye had exophthalmos, subconjunctival hyperemia, scleral edema/chemosis and ocular bruit. Neurologic examination showed a stuporous patient with multiple cranial nerve deficits (impaired direct and consensual pupillary reflex left, complete ptosis left, sluggish corneal reflex left, impaired oculocephalic reflex left), right hemiplegia and meningeal signs. Cranial Computed Tomography (CT) Angiogram revealed an acute parenchymal hemorrhage in the left frontotemporal lobe with subarachnoid component, with engorged left cavernous sinus and dilated left superior ophthalmic vein. Digital Subtraction Angiography (DSA) was done revealing a direct type of left carotid-cavernous fistula with massive ICA shunting to the cavernous sinus, superior ophthalmic vein and inferior petrosal sinus. The clinical and radiographic evidence were consistent with a Direct/Type A CCF. Unique in this case was a patient with no history of trauma presenting with simultaneous orbital/ocular, cavernous and cortical symptomatology – a clinical picture of CCF that has never been documented in any literature nor included in any classification system. The presence of all three symptomatology can be explained by a direct/highflow fistula that resulted to increased anterior, posterior and superior venous drainage as documented in the DSA. In addition, spontaneous intracranial hemorrhage in CCF is exceptionally rare and it is the most daunting symptomatology of this disease. With that, this specific case may pave the way to a new classification scheme and determine its corresponding treatment approach.

BACKGROUND: Controversies exist whether arteriovenous fistula (AVF) placement is preferred over arteriovenous graft (AVG) for elderly patients. Current guidelines did not offer specific recommendations. Thus, this study was conducted to analyze the all-cause mortality and primary patency associated with various vascular access (VA) types according to age group. METHODS: This retrospective observational study investigated the Korean insurance claims data of chronic kidney disease patients who began hemodialysis between January 2008 and December 2016. We investigated all-cause mortality associated with initial VA in incident hemodialysis patients and primary patency between AVF and AVG according to age group. RESULTS: The proportion of patients with a tunneled dialysis catheter (TDC) that was first placed for VA increased from 18.4% in 2008 to 52.3% in 2016. Incident hemodialysis patients with a TDC or AVG for the initial VA had significantly higher mortality risk than patients with an AVF, except for patients over 85 years, who showed no significant difference in all-cause mortality regardless of VA type. In the patency analysis on initial AV access, AVG had significantly poorer primary patency than AVF in all age groups. CONCLUSION: AVF had better patency than AVG in all age groups; however, the benefit of AVF attenuated in the older age groups. The mortality rate between AVF and AVG was not significantly different in patients over 85 years. Therefore, a “patient-first” approach should be emphasized over a “fistula-first” approach in AV access creation for incident hemodialysis patients older than 85 years.

Central venous disease (CVD) is difficult to treat and often resistant to treatment. In CVD, hemodialysis vascular access should sometimes be abandoned, or in serious cases, the patient's life may be threatened. Therefore, prevention is ideal. However, as the prevalence of chronic kidney disease (CKD) has increased steadily with population aging, CKD patients with a peripherally inserted central catheter (PICC) are encountered frequently. PICCs can cause CVD, and the basilic vein, which is regarded as the important last option for native arteriovenous fistula (AVF) creation in end-stage renal disease (ESRD) patients, is destroyed frequently after its use as the entry site of PICC. The most well-established risk factors for CVD are a history of central venous catheter (CVC) insertion and its duration of use. Therefore, to reduce the incidence of CVD, catheterization in the central vein (CV) should be minimized, along with its duration of use. In this review, we will first explain the basic territories of the CV and introduce its pathophysiology, clinical features, and advanced treatment options. Finally, we will emphasize prevention of CVD.

OBJECTIVE: To evaluate the efficacy of ultrasound or fluoroscopic-guided percutaneous transluminal angioplasty (PTA) combined with thrombolysis for the treatment of acutely thrombosed arteriovenous fistula (AVF) or grafts (AVG). METHODS: One hundred and ninety-two hemodialysed patients, in whom the thrombosed arterio-venous AVF or AVG developed less than 72 h and there were no contraindications for thrombolysis and PTA, underwent PTA combined with thrombolysis therapy in Sir Run Run Shaw Hospital of Zhejiang University from October 2014 to October 2017. Under ultrasound and/or fluoroscopic guidance, balloon catheter was introduced to thrombosis sites along a guide wire. Then the balloon was inflated and normal saline mixed with urokinase and heparin was injected for thrombolysis. After blood flow was restored, angioplasty was performed on vascular stenosed sites. RESULTS: A total of 274 endovascular interventional operations were performed for 192 patients. The procedure success rate was 98.2%, clinical success rate was 93.8%and complication rate was 1.46%. The post-intervention primary patency rates for AVF group were 87.4%, 76.7%and 63.9%at 3, 6 and 12 months, respectively; while the post-intervention secondary patency rates were 93.7%, 91.6%and 83.0%, respectively. The post-intervention primary patency rates for AVG group were 60.7%, 51.5%and 43.1%at 3, 6 and 12 months, while the post-intervention secondary patency rates were 82.7%, 77.1%and 70.8%, respectively. CONCLUSIONS PTA combined with thrombolysis is an effective and safe therapeutic option for AVF and AVG thrombosis, which would prolong hemodialysis access and save vascular resources for hemodialyzed patients.
