Bilateral traumatic carotid-cavernous fistula(CCF)is rare. It is most commonly caused by a direct head or face injury involving the cavernous sinus and develops immediately after trauma. We report a case of bilateral traumatic CCF that occurred as an intracerebral hematoma(ICH)mimicking apoplexy 5 months later. We treated the patient with point occlusion of venous reflux causing an ICH using coil embolization to remove the hematoma. Three days after we performed trans-venous occlusion of the intercavernous connection and right cavernous sinus using coil embolization through the right inferior petrosal vein, it was identified that the left CCF was occluded after first embolization into the left sylvian vein...

BACKGROUND: The Effect of Surgery and Compression on Healing and Recurrence (ESCHAR) trial previously reported that patients with venous leg ulcers treated with saphenous stripping experienced a significantly reduced incidence of ulcer recurrence compared with patients treated with compression therapy. Most patients with leg ulcers and saphenous insufficiency are currently treated with endovenous thermal ablation (EVTA), but little information is available on the long-term results after EVTA in Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) clinical class 5 (C5) and class 6 (C6) patients...

The jet of fluid returning to the patient through a hemodialysis venous needle has previously been reported as a potential source of endothelial damage which can lead to intimal hyperplasia (IH) in arteriovenous fistulae (AVF). Metal needles are the current standard practice for accessing the vascular system in hemodialysis. However, plastic cannulae have been used in Japan for 30 years. This study utilized computational fluid dynamics to analyze the hemodynamics of blood exiting a plastic cannula and determined the optimal placement and blood flow rate...

Purpose To investigate whether sinovenous outflow restriction (SOR) is more strongly associated with hemorrhage than cortical venous reflux (CVR) in patients with lateral sinus dural arteriovenous fistulas (DAVFs). Materials and Methods An institutional review board approved this retrospective study and waiver of informed consent was obtained. From 1995 to 2016, 163 cases of lateral sinus DAVFs were included and divided into hemorrhagic and nonhemorrhagic groups based on initial presentation. Their angiograms and magnetic resonance images were evaluated, with two evaluators independently grading CVR and SOR...

BACKGROUND: Magnetic resonance spectroscopy (MRS) is a potentially useful modality for evaluating brain metabolites in patients with dural arteriovenous fistula (dAVF). Here, we propose a different pattern of MRS-based cerebral metabolism findings in patients with dAVF. CASE DESCRIPTION: We performed MRS in three patients with transverse sigmoid sinus dAVF associated with cortical venous reflux. In case 1, which was associated with vasogenic edema on T2-weighted imaging, decreasing preoperative N-acetylaspartate/creatine, myo-inositol/creatine and increasing lactate/creatine ratios improved after treatment...

Dural arteriovenous fistulas are abnormal communications, within the dural leaflets, between meningeal arteries and dural venous sinuses and/or subarachnoid veins. Although many fistulas remain clinically silent and do not require treatment, presence of cortical venous reflux, intracranial bleed, and intolerable symptoms are the main indications for treatment. A thorough understanding of the natural history is of prime importance in the decision making and management of these lesions. In this chapter we discuss the epidemiology and natural history of intracranial dural arteriovenous fistulae...

Spinal vascular malformations include several types of pathologic entities with multiple variations in their neurologic presentation and risks. Spinal dural arteriovenous fistulae (SDAVF) are the most frequent type, and account for 70% of all lesions affecting the spinal cord. The nonspecific early neurologic symptoms of SDAVF often make early diagnosis of this clinical entity challenging, and a delay in diagnosis or appropriate treatment often has devastating consequences on spinal cord function. The lesion can invariably be obliterated with surgical occlusion of the intradural arterialized venous reflux, and progression of neurologic deficits is usually arrested and sometimes reversed...

Dural arteriovenous fistulae are high flow, low resistance intracranial vascular malformations defined by an aberrant connection between an artery and dural vein or sinus. Symptomatology and presentation are highly dependent on location, generally categorized as supratentorial, tentorial, or infratentorial, and consist primarily of sequelae secondary to local venous hypertension, insufficiency, and cortical venous reflux. Surgery is generally reserved for high risk or persistently symptomatic lesions that are unamenable or unresponsive to endovascular therapy...

PURPOSE: A continuous spermatic venous reflux (SVR) at colour Doppler ultrasound (CDU) is an evidence for varicocele, a frequent correlate for male subfertility. We explored whether SVR after left varicocele repair is predictive for changes in semen quality in subfertile men. METHODS: Blood hormones (FSH, LH, and total testosterone) and scrotal CDU were obtained in subfertile patients with left grade II or grade III varicocele on physical evaluation and a poor sperm quality...

Objective Ultrasound-guided foam sclerotherapy (UGFS) - one of the most frequently recommended methods for treating great saphenous vein incompetence - is easy and inexpensive. However, it achieves a lower occlusion rate compared to endovenous thermal ablation. The application of UGFS to pre-terminal great saphenous vein interruption, eliminating the saphenous stem wash out effect, enhances the short-term occlusion rate. This study explores the results of this technique at 12 months. Method Thirty great saphenous veins (28 patients) with junction incompetence, with calibres >6 mm and >30 cm reflux stem length were submitted to echo-guided pre-terminal great saphenous vein interruption and foam great saphenous vein occlusion...

Essentials Acute iliofemoral deep vein thrombosis can be treated with catheter-directed thrombolysis (CDT). We performed a randomized trial comparing conventional CDT versus ultrasound-assisted CDT (USAT). Clinical and duplex sonographic outcomes at 12 months were similar in the CDT and USAT groups. In both groups, incidence of postthrombotic syndrome was very low with good quality of life. SUMMARY: Background In patients with acute iliofemoral deep vein thrombosis (IFDVT), catheter-directed thrombolysis (CDT) aims to prevent the postthrombotic syndrome (PTS)...
