Introduction: Dural arteriovenous fistulas account for 10 to 15% of intracranial malformations. They are defined as malformations short-circuits between dural and extracranial arteries with venous sinuses. Its presentation is in frequent its management a challenge low- middle-income countries where there difficulties accessing high quality technological tools. Case: We present the case an unusu...

BACKGROUND Central venous pressure (CVP) provides important information for the management of critically ill patients. The external jugular vein (EJV) is easier to visualize than the internal jugular vein and may give a reliable estimate of CVP. METHODS To determine the usefulness of the EJV examination in detecting abnormal CVP values, we performed a prospective blinded evaluation comparing ...

Bradykinin caused graded contractions of rings of rabbit aorta and jugular vein with EC50 values of 1.3 microM and 2.2 nM. In denuded preparations, responses of bradykinin in jugular vein but not in aorta were potentiated 1,000-fold. Both preparations bathed in calcium-free solution showed markedly depressed responses to bradykinin, but addition of 1 mM EGTA further inhibited bradykinin respons...

REASONS FOR PERFORMING STUDY The transverse facial venous sinus (TFVS) can be used for blood collection in horses, but information on the validity of blood values from this site is limited. OBJECTIVES To determine if packed cell volume (PCV), total solids (TS) and blood lactate concentrations in blood drawn simultaneously from a TFVS and jugular vein of critically ill horses are correlated an...

Nontunneled hemodialysis catheters (NTHCs) are typically used when vascular access is required for urgent renal replacement therapy. The preferred site for NTHC insertion in acute kidney injury is the right internal jugular vein followed by the femoral vein. When aided by real-time ultrasound, mechanical complications related to NTHC insertion are significantly reduced. The preferred site for t...

RATIONALE Cerebral venous thrombosis (CVT) comprises a group of cerebral vascular diseases resulting from cerebral venous outflow obstruction caused by various etiologies. The etiology of CVT is complex, including infectious and noninfectious factors. The diagnosis is difficult. As a result, many patients are misdiagnosed or never diagnosed. This patient was diagnosed with CVT due to unilateral...
