We report a case of pulsatile varicose veins successfully managed by endovenous laser treatment (EVLT) of the great saphenous vein (GSV). A 77-year-old woman taking an anticoagulant was transferred to our hospital for pulsatile varicose veins complicated with repeated venous bleeding from an ulcer of her left lower leg. Doppler echocardiography showed severe tricuspid regurgitation, and duplex ultrasonography revealed an arterial-like pulsating flow in the saphenofemoral junction and along the GSV, but an arteriovenous fistula, obstruction of the deep veins, and the distal incompetent perforators were not detected...

BACKGROUND: A mathematical model to help explain the hemodynamic characteristics of perforator flaps based on blood flow resistance systems within the flap will serve as a theoretical guide for the future study and clinical applications of these flaps. METHODS: There are 3 major blood flow resistance network systems of a perforator flap. These were defined as the blood flow resistance of an anastomosis between artery and artery of adjacent perforasomes, between artery and vein within a perforasome, and then between vein and vein corresponding to the outflow of that perforasome...

Patients receiving methotrexate (MTX) for the treatment of autoimmune disease are at a high risk of developing lymphoproliferative disorders (LPD), the so-called methotrexate-associated lymphoproliferative disorders (MTX-LPD). We recently performed abdominal ultrasonography (US) in a patient with rheumatoid arthritis (RA) who had developed hepatic dysfunction during the course of MTX therapy; the examination revealed multiple well-demarcated hepatic tumors with slightly irregular borders, the largest one measuring 9 cm in diameter...

Our new modification is a perforator cheek island flap. Flap pedicle is solely based on the facial artery and vena comitans on its surface without facial vein, which is usually sacrified during level I node dissection in most of head and neck cancer surgeries. Our new flap can utilize the entire cheek mucosal area, larger than conventional facial artery myomucosal flap to repair various upper aerodigestive tract defects after head and neck cancer ablation irrespective of pre/postoperative irradiation. The procedure for our flap is more simplified than that of the existing tunnelized facial artery myomucosal island flap...

BACKGROUND: Vertebroplasty carries multiple complications due to the leakage of polymethylmethacrylate (PMMA) into the venous system through the iliolumbar or epidural veins. The rate of venous cement complications may vary from 1 to 10 %, with cement extravasation into the venous system in 24 % of patients. Emboli may further migrate into the right heart chambers and pulmonary arteries. Patients may vary in presentation from asymptomatic or symptoms such as syncope to life-threatening complications...

Although vessel perforation rarely occurs during percutaneous transluminal angioplasty of a central venous stenosis, it can be a rapidly fatal complication when accompanied by pericardial tamponade. The present case report details our experience with this dangerous complication. It also highlights the risk factors for and the pathogenesis of central venous stenosis, the clinical findings associated with inadvertent vessel perforation during an intervention, and anesthetic management strategies for pericardial tamponade resulting from vessel perforation...

BACKGROUND/AIM: The aim of this paper was to present our 3-year multicenter experience in creating a vascular access using the basilic vein. The third choice in creating vascular access is the brachiobasilic arteriovenous fistula (AVFs) with transposition of the basilic vein. MATERIALS AND METHODS: During 2010-2012, out of a total of 874 AVFs that were performed in our two centers, 54 were brachiobasilic fistulas (6.71%), performed on 54 patients. All surgical procedures were performed by two surgical teams, one for each center...

BACKGROUND: The current gold standard for preoperative perforator mapping in breast reconstruction with a DIEP flap is CT angiography (CTA). Dynamic infrared thermography (DIRT) is an imaging method that does not require ionizing radiation or contrast injection. We evaluated if DIRT could be an alternative to CTA in perforator mapping. METHODS: Twenty-five patients scheduled for secondary breast reconstruction with a DIEP flap were included. Preoperatively, the lower abdomen was examined with hand-held Doppler, DIRT and CTA...

A 70-year-old woman with persistent atrial fibrillation underwent pulmonary vein isolation and linear ablation with a contact sensor catheter. During cavotricuspid isthmus ablation, a steam pop resulted in cardiac tamponade, and the patient developed severe hypotension despite successful pericardial puncture and minimal residual pericardial effusion. Right coronary artery angiography revealed extravasal contrast medium accumulation posterior of the Crux Cordis. Emergent cardiac surgery confirmed isolated disruption of the artery in the absence of additional heart perforation...
