Blood pressure is a critical parameter for evaluating cardiovascular health, assessing effects of drugs and procedures, monitoring physiologic status during anesthesia, and making clinical decisions. The placement of an arterial catheter is the most direct and accurate method for measuring blood pressure; however, this approach is invasive and of limited use during brief sedated examinations. The objective of this study was to determine which method of indirect blood pressure monitoring was most accurate compared with measurement by direct arterial catheterization...

This study in α-chloralose anesthetized cats aimed at investigating the bladder responses to saphenous nerve stimulation (SNS). A urethral catheter was used to infuse the bladder with saline and to record changes in bladder pressure. With the bladder fully distended, SNS at 1 Hz frequency and an intensity slightly below the threshold (T) for inducing an observable motor response of the hindlimb muscles induced large amplitude (40-150 cmH2O) bladder contractions. Application of SNS (1 Hz, 2-4T) during cystometrograms (CMGs), when the bladder was slowly (1-3 ml/min) infused with saline, significantly (p<0...

Dynamic ultrasound-guided short-axis needle tip navigation is a novel technique for vascular access. After venipuncture, the needle and catheter are further advanced within the vessel lumen under real-time ultrasound guidance with constant visualisation of the needle tip in the short-axis view. This can minimise the risk of transfixing the cannulated vessel. We compared two techniques for non-visible saphenous vein cannulation under general anaesthesia in children weighing ≥ 3 kg and less than four years of age: dynamic ultrasound-guided short-axis needle tip navigation technique (ultrasound group) vs...

A 73-year-old man, who had undergone coronary artery bypass grafting (CABG) 10 days prior, presented with a great saphenous vein graft aneurysm (SVGA). CT revealed the increasing size of the aneurysm. Since the SVGA occurred immediately after CABG and there were no other complications, the aneurysm was treated percutaneously. While intravascular ultrasonography (IVUS) and optical coherence tomography failed to detect the entry point, an IVUS catheter with the addition of ChromaFlo imaging clearly revealed the entry point, size and length of the SVGA...

An arteriovenous fistula in a limb involves an abnormal connection between a limb artery and vein. It can be due to trauma or iatrogenic injury. Traumatic arteriovenous fistulas can be caused by penetrating or gunshot injuries to the limb, while iatrogenic causes include catheter intervention to the groins or open surgery of the inguinal space. By contrast, the occurrence of multiple spontaneous arteriovenous fistulas is rare. We report a case of endovascular therapy for multiple spontaneous arteriovenous fistulas between the iliac artery and the vein, common femoral artery and the vein, superficial artery and the saphenous vein, and deep femoral artery and the vein...

BACKGROUND: Varices and venous insufficiency are common and serious health problems in the general population which affect the quality of life. Endothermal treatment of the great saphenous vein has become the first line of treatment for superficial venous reflux, and the endovenous laser ablation (EVLA) method has been widely accepted all over the world. In this method, ablation is provided by a laser fiber inserted into the lumen of the vein. Initially, the fibers were 810 nm, but today the fibers are usually 940, 980, or 1470 nm...

BACKGROUND AND OBJECTIVES: Patients undergoing major elective ankle surgery often experience pain from the saphenous nerve territory persisting beyond the duration of a single-injection saphenous nerve block. We hypothesized that perineural dexamethasone as an adjuvant for the saphenous nerve block prolongs the duration of analgesia and postpones as well as reduces opioid-requiring pain. METHODS: Forty patients were included in this prospective, randomized, controlled study...

An 86-year-old female patient with a history of bypass surgery was admitted for recurrent dyspnea and chest pain on exertion. She underwent coronary angiography showing high-grade saphenous vein graft stenosis supplying the right coronary. During an attempt to perform percutaneous intervention, saphenous vein graft to the right coronary artery was injured by the guide catheter resulting in dissection with thrombus formation but with normal distal blood flow. The procedure was abandoned since she had normal distal flow and also due to a fear of causing extension of the dissection with further manipulation...
