The dehiscence of saphenous vein grafts (SVGs) is a rare, often fatal, complication of coronary artery bypass grafting (CABG). We present the case of a 57-year-old man who underwent hemiarch graft interposition and CABG for a Stanford type A aortic dissection. Five months after discharge, the patient developed streptococcal sepsis caused by a hemodialysis catheter. Complete rupture of the proximal anastomoses of the saphenous veins and containment by the obliterated pericardial cavity was observed 25 months after the initial operation...

BACKGROUND: Endovenous radio frequency ablation for small saphenous vein incompetence by and large appears to be superior and safer than conventional open surgery. Small saphenous vein ablation from approximately mid-calf to the point proximally where the small saphenous vein dives into the popliteal fossa is considered to be safe, as the sural nerve is in most cases separated from this segment of the small saphenous vein by the deep fascia. The outcome of the distal incompetent small saphenous vein remains unclear...

The presence of cold agglutinins (CA) during cardiac surgery with cardiopulmonary bypass usually creates the need for an altered surgical plan. In this case, the CA were discovered after the initiation of bypass, limiting the time, and cardioplegia solutions that could be used in the new approach. The inability to cannulate the coronary sinus with a retrograde cardioplegia catheter excluded the standard approach to myocardial preservation with CA of using continuous warm blood. For this case, we used intermittent cold crystalloid delivered via the antegrade needle for the first half of the procedure and through the saphenous vein graft anastomosis during the aortic valve portion of the cross-clamp period...

BACKGROUND There is little data comparing catheter-directed thrombolysis (CDT) via small saphenous veins vs. systematic thrombolysis on complications and efficacy in acute deep venous thrombosis patients. The aim of our study was to compare the efficacy and safety of CDT via the small saphenous veins with systematic thrombolysis for patients with acute deep venous thrombosis (DVT). MATERIAL AND METHODS Sixty-six patients with acute DVT admitted from June 2012 to December 2013 were divided into 2 groups: 27 patients received systemic thrombolysis (ST group) and 39 patients received CDT via the small saphenous veins (CDT group)...

OBJECTIVE: Mechanochemical ablation is a novel technique for ablation of varicose veins utilising a rotating catheter and liquid sclerosant. Mechanochemical ablation and radiofrequency ablation have no reported neurological side-effect but the rotating mechanism of mechanochemical ablation may produce microbubbles. Air emboli have been implicated as a cause of cerebrovascular events during ultrasound-guided foam sclerotherapy and microbubbles in the heart during ultrasound-guided foam sclerotherapy have been demonstrated...

Distal embolization of a fractured indwelling central catheter is a rare complication. The pinch-off syndrome (POS) should be known, prevented and early detected. We present a case in which further radiological exams were required to find the fragmented catheter with an atypical migration, requiring local surgery for removing. After chest and abdominal CT scan, neck X-ray, and heart echography, the catheter was found on the lower limbs X-ray on the internal side of right knee corresponding to a location of saphenous vein...

Iatrogenic dissections of the ascending aorta are an uncommon and severe complication during cardiac catheterization. A 68-year-old female patient underwent diagnostic cardiac catheterization due to non-ST-elevation myocardial infarction. During the procedure, a catheter-induced 360(°) Class I dissection of the right coronary artery occurred. The patient developed severe bradycardia, which was treated with a temporary pacemaker. She underwent an emergency operation with ligation and a saphenous vein graft in the right coronary artery...

Although endovenous heat-induced thrombosis (EHIT) is frequently reported after endovenous laser ablation (EVLA), the incidence and timing of occurrence of EHIT are not fully understood. We present a case of EHIT successfully treated with a combination of surgical and endovascular treatments. A 57-year-old woman, two months post bilateral EVLA, presented with a swollen leg. Deep vein thrombosis was diagnosed by Doppler ultrasonography and computerized tomographic venography. We treated the patient with catheter-directed thrombolysis with urokinase after insertion of an inferior vena cava filter...

BACKGROUND: Excimer laser coronary atherectomy (ELCA) recently became available in Japan, but ELCA's effectiveness and safety are not clear. METHODS AND RESULTS: We enrolled consecutive patients who underwent ELCA and were registered in the Utility of Laser for Transcatheter Atherectomy-Multicenter Analysis around Naniwa (ULTRAMAN) registry comprising six Japanese medical centers around Naniwa in Japan with patients registered from April 2006 to June 2015. We evaluated the catheter sizes used and compared the success rate, thrombolysis in myocardial infarction (TIMI) flow, blush score, and complications between the rich-thrombus (RT) group [acute coronary syndrome (ACS) and saphenous vein graft (SVG)] and the poor-thrombus (PT) group [in-stent restenosis (ISR), chronic total occlusion (CTO), calcification, and long or bifurcation (L&B) lesions]...

Patients with advanced post-thrombotic syndrome (PTS) and chronic iliac vein obstruction suffer major physical limitations and impairment of health-related quality of life. Currently there is a lack of evidence-based treatment options for these patients. Early studies suggest that imaging-guided, catheter-based endovascular therapy can eliminate iliac vein obstruction and saphenous venous valvular reflux, resulting in reduced PTS severity; however, these observations have not been rigorously validated. A multidisciplinary expert panel meeting was convened to plan a multicenter randomized controlled clinical trial to evaluate endovascular therapy for the treatment of advanced PTS...

INTRODUCTION: Percutaneously inserted central venous catheters (epicutaneo-cava-catheter - ECC) are widely used in neonatal intensive care, facilitating the parenteral nutrition and the treatment of critically ill newborns. This invasive procedure is regarded as safe and associated with low complication rate. Possible life-threatening complications may result from malpositioning of ECC. Paraspinal misplacement of ECC is one of the most serious complications. CASE PRESENTATION: The authors report a case of misplacement of ECC inserted via left saphenous vein for intravenous feeding...

PURPOSE: Native arteriovenous fistula (AVF) is the ideal vascular access for hemodialysis. Once upper extremity vessels are exhausted or not suitable for AVF creation, the remaining options were either arteriovenous graft (AVG) or lower limb arteriovenous fistula. METHODS: A 45-year-old male patient with chronic kidney disease (CKD) stage V was initiated on hemodialysis through a central venous catheter. He was referred for AVF creation after failed left radiocephalic AVF...

BACKGROUND: Adductor canal block (ACB) has emerged as an appealing alternative to femoral nerve block (FNB) that produces a predominantly sensory nerve block by anesthetizing the saphenous nerve. Studies have shown greater quadriceps strength preservation with ACB compared with FNB, but no advantage has yet been shown in terms of fall risk. The Tinetti scale is used by physical therapists to assess gait and balance, and total score can estimate a patient's fall risk. We designed this study to test the primary hypothesis that FNB results in a greater proportion of "high fall risk" patients postoperatively using the Tinetti score compared with ACB...

INTRODUCTION: Endovascular radiofrequency with first generation catheters was not successful due to its technical difficulty and restrictions in veins with diameters larger than 12mm. However, using the new catheter there is not enough scientific evidence to affirm that the diameter represents a technical limitation. The aim of this study was to evaluate and compare pre and post-operative venous trunks diameter, aiming at the reduction of size after 6 months with last generation catheters...

Regardless of the clinical setting, a good back-up represents one of the most important conditions to ensure guide wire and balloon advancement and stent delivery. As a "mother and child" system, the GuideLiner catheter (Vascular Solutions Inc., Minneapolis, MN, USA) provides an extension to the guide catheter with better coaxial alignment and stability. We report two didactic cases showing the usefulness of the GuideLiner device in everyday catheterization laboratory practice. The first case was a primary percutaneous coronary intervention (PCI) in a 71-year-old diabetic man admitted for inferior ST-elevation myocardial infarction, related to tight proximal stenosis in a dominant tortuous and calcified left circumflex...

OBJECTIVE: During maturation the vascular system undergoes structural and functional remodeling. At the systemic level it results in a gradual increase of arterial blood pressure during postnatal ontogenesis. The mechanisms of maintaining the blood pressure at a comparatively low level during the early postnatal development are not completely understood. Recently we showed that the hindlimb arteries of young (1-2 wk-old) rats exhibited an enhanced endothelial NO-pathway activity, which weakened their contractile responsiveness compared to the arteries of adult rats...
