Detection of Chlamydia pneumoniae but not cytomegalovirus in occluded saphenous vein coronary artery bypass grafts. (1/1721)

BACKGROUND: A causal relation between atherosclerosis and chronic infection with Chlamydia pneumoniae and/or cytomegalovirus (CMV) has been suggested. Whether the unresolved problem of venous coronary artery bypass graft occlusion is related to infection with C pneumoniae and/or CMV has not been addressed. METHODS AND RESUTLS: Thirty-eight occluded coronary artery vein grafts and 20 native saphenous veins were examined. Detection of C pneumoniae DNA was performed by use of nested polymerase chain reaction (PCR). Homogenisates from the specimen were cultured for identification of viable C pneumoniae. Both conventional PCR and quantitative PCR for detection of CMV DNA were applied. Differential pathological changes (degree of inflammation, smooth muscle cell proliferation [MIB-1]) were determined and correlated to the detection of both microorganisms. C pneumoniae DNA could be detected in 25% of occluded vein grafts. Viable C pneumoniae was recovered from 16% of occluded vein grafts. Except for 1 native saphenous vein, all control vessels were negative for both C pneumoniae detection and culture. All pathological and control specimens were negative for CMV DNA detection. Pathological changes did not correlate with C pneumoniae detection. CONCLUSIONS: Occluded aorto-coronary venous grafts harbor C pneumoniae but not CMV. The detection of C pneumoniae in occluded vein grafts warrants further investigation.  (+info)

The cyclo-oxygenase-dependent regulation of rabbit vein contraction: evidence for a prostaglandin E2-mediated relaxation. (2/1721)

1. Arachidonic acid (0.01-1 microM) induced relaxation of precontracted rings of rabbit saphenous vein, which was counteracted by contraction at concentrations higher than 1 microM. Concentrations higher than 1 microM were required to induce dose-dependent contraction of vena cava and thoracic aorta from the same animals. 2. Pretreatment with a TP receptor antagonist (GR32191B or SQ29548, 3 microM) potentiated the relaxant effect in the saphenous vein, revealed a vasorelaxant component in the vena cava response and did not affect the response of the aorta. 3. Removal of the endothelium from the venous rings, caused a 10 fold rightward shift in the concentration-relaxation curves to arachidonic acid. Whether or not the endothelium was present, the arachidonic acid-induced relaxations were prevented by indomethacin (10 microM) pretreatment. 4. In the saphenous vein, PGE2 was respectively a 50 and 100 fold more potent relaxant prostaglandin than PGI2 and PGD2. Pretreatment with the EP4 receptor antagonist, AH23848B, shifted the concentration-relaxation curves of this tissue to arachidonic acid in a dose-dependent manner. 5. In the presence of 1 microM arachidonic acid, venous rings produced 8-10 fold more PGE2 than did aorta whereas 6keto-PGF1alpha and TXB2 productions remained comparable. 6. Intact rings of saphenous vein relaxed in response to A23187. Pretreatment with L-NAME (100 microM) or indomethacin (10 microM) reduced this response by 50% whereas concomitant pretreatment totally suppressed it. After endothelium removal, the remaining relaxing response to A23187 was prevented by indomethacin but not affected by L-NAME. 7. We conclude that stimulation of the cyclo-oxygenase pathway by arachidonic acid induced endothelium-dependent, PGE2/EP4 mediated relaxation of the rabbit saphenous vein. This process might participate in the A23187-induced relaxation of the saphenous vein and account for a relaxing component in the response of the vena cava to arachidonic acid. It was not observed in thoracic aorta because of the lack of a vasodilatory receptor and/or the poorer ability of this tissue than veins to produce PGE2.  (+info)

Arterial flow conditions downregulate thrombomodulin on saphenous vein endothelium. (3/1721)

BACKGROUND: The antithrombogenic properties of venous endothelium may be attenuated when vein is implanted in the arterial circulation. Such changes may facilitate thrombosis, which is the final common pathway for saphenous vein arterial bypass graft occlusion. METHODS AND RESULTS: Using human saphenous vein in a validated ex vivo flow circuit, we investigated (1) the possibility that arterial flow conditions (mean pressure, 100 mm Hg, 90 cpm, approximately 200 mL/min) alter the concentration of proteins involved in regulating thrombosis at the vessel wall and (2) the influence of ion channel blockade on such effects. Concentrations of thrombomodulin and tissue factor were quantified by Western blotting (ratio of von Willebrand factor staining) and immunohistochemistry (as a percentage of CD31-staining area). Thrombomodulin concentrations after 90 minutes of venous and arterial flow conditions were quantified by immunostaining (68.9+/-4.8% and 41.0+/-3.0% CD31, respectively; P<0.01) and by Western blotting (1.35+/-0.20 and 0. 15+/-0.03 ratio of von Willebrand factor, respectively; P<0.01). The ability of endothelial cells to generate activated protein C also decreased from 62+/-14 to 19+/-10 ng. min-1. 1000 cells-1 (P=0.01). The significant reduction in thrombomodulin was attenuated if calcium was removed from the perfusate but not by external vein stenting. Inclusion in the vein perfusate of drugs that reduce calcium entry (including Gd3+, to block stretch-activated ion channels, and nifedipine) abolished the reduction in thrombomodulin concentration observed after arterial flow conditions. In freshly excised vein, negligible concentrations of tissue factor were detected on the endothelium and concentrations did not increase after 90 minutes of arterial flow conditions, although the inclusion of nifedipine caused the immunostaining to increase from 3.0+/-0.4% to 8.5+/-0.7% CD31 (P<0.02). CONCLUSIONS: In saphenous vein endothelium exposed to arterial flow conditions, there is rapid downregulation of thrombomodulin, sufficient to limit protein C activation, by a calcium-dependent mechanism.  (+info)

Venous ulceration and continuous flow in the long saphenous vein. (4/1721)

OBJECTIVE: To determine the clinical significance of continuous flow in the long saphenous vein in limbs with venous ulceration. DESIGN: Retrospective review. PATIENTS AND METHODS: Review of 1608 consecutive limbs undergoing colour duplex scanning for venous disease over a 43 month period. RESULTS: Continuous flow in the long saphenous vein is seen in 8% of limbs with venous ulceration and in 37% of limbs with deep venous obstruction. Sixty-six per cent of ulcerated limbs with continuous flow in the long saphenous vein had deep venous obstruction, 27% had deep venous reflux with cellulitis and 7% had lymphoedema in addition to venous ulceration. CONCLUSION: Continuous flow in the long saphenous vein in patients with venous ulceration should alert the clinician to the possibility of deep venous obstruction. Such limbs should be treated by compression bandaging with extreme caution.  (+info)

Isolated femoropopliteal bypass graft for limb salvage after failed tibial reconstruction: a viable alternative to amputation. (5/1721)

PURPOSE: Femoropopliteal bypass grafting procedures performed to isolated popliteal arteries after failure of a previous tibial reconstruction were studied. The results were compared with those of a study of primary isolated femoropopliteal bypass grafts (IFPBs). METHODS: IFPBs were only constructed if the uninvolved or patent popliteal segment measured at least 7 cm in length and had at least one major collateral supplying the calf. When IFPB was performed for ischemic lesions, these lesions were usually limited to the digits or small portions of the foot. Forty-seven polytetrafluoroethylene grafts and three autogenous reversed saphenous vein grafts were used. RESULTS: Ankle brachial pressure index (ABI) increased after bypass grafting by a mean of 0.46. Three-year primary life table patency and limb-salvage rates for primary IFPBs were 73% and 86%, respectively. All eight IFPBs performed after failed tibial bypass grafts remained patent for 2 to 44 months, with patients having viable, healed feet. CONCLUSION: In the presence of a suitable popliteal artery and limited tissue necrosis, IFPB can have acceptable patency and limb-salvage rates, even when a polytetrafluoroethylene graft is used. Secondary IFPB can be used to achieve limb salvage after failed tibial bypass grafting.  (+info)

Superficial femoral eversion endarterectomy combined with a vein segment as a composite artery-vein bypass graft for infrainguinal arterial reconstruction. (6/1721)

OBJECTIVE: The purpose of this study was to determine the results of composite artery-vein bypass grafting for infrainguinal arterial reconstruction. METHODS: This study was designed as a retrospective case series in two tertiary referral centers. Forty-eight of 51 patients underwent the procedure of interest for the treatment of ischemic skin lesions (n = 42), rest pain (n = 3), disabling claudication (n = 1), and infected prosthesis (n = 2). The intervention used was infrainguinal composite artery-vein bypass grafting to popliteal (n = 18) and infrapopliteal (n = 30) arteries, with an occluded segment of the superficial femoral artery prepared with eversion endarterectomy and an autogenous vein conduit harvested from greater saphenous veins (n = 43), arm veins (n = 3), and lesser saphenous veins (n = 2). The main outcome measures, primary graft patency rates, foot salvage rates, and patient survival rates, were described by means of the life-table method for a mean follow-up time of 15.5 months. RESULTS: The cumulative loss during the follow-up period was 6% and 24% at 6 and 12 months, respectively. The primary graft patency rates, the foot salvage rates, and the patient survival rates for patients with popliteal grafts were 60.0% +/- 9.07%, 75.7% +/- 9.18%, and 93.5% +/- 6.03%, respectively, at 1 month; 53.7% +/- 11.85%, 68.9% +/- 12.47%, and 85. 0% +/- 9.92% at 1 year; and 46.7% +/- 18.19%, 68.9% +/- 20.54%, and 53.1% +/- 17.15% at 5 years. For infrapopliteal grafts, the corresponding estimates were 72.4% +/- 7.06%, 72.9% +/- 6.99%, and 92.7% +/- 4.79% at 1 month; 55.6% +/- 10.70%, 55.4% +/- 10.07%, and 77.9% +/- 9.02% at 1 year; and 33.6% +/- 22.36%, 55.4% +/- 30.20%, and 20.8% +/- 9.89% at 5 years. CONCLUSION: The composite artery-vein bypass graft is a useful autogenous alternative for infrainguinal arterial reconstruction when a vein of the required quality is not available or when the procedure needs to be confined to the affected limb.  (+info)

Mid-term results of endoscopic perforator vein interruption for chronic venous insufficiency: lessons learned from the North American subfascial endoscopic perforator surgery registry. The North American Study Group. (7/1721)

PURPOSE: The safety, feasibility, and early efficacy of subfascial endoscopic perforator surgery (SEPS) for the treatment of chronic venous insufficiency were established in a preliminary report. The long-term clinical outcome and the late complications after SEPS are as yet undetermined. METHODS: The North American Subfascial Endoscopic Perforator Surgery registry collected information on 148 SEPS procedures that were performed in 17 centers in the United States and Canada between August 1, 1993, and February 15, 1996. The data analysis in this study focused on mid-term outcome in 146 patients. RESULTS: One hundred forty-six patients (79 men and 67 women; mean age, 56 years; range, 27 to 87 years) underwent SEPS. One hundred and one patients (69%) had active ulcers (class 6), and 21 (14%) had healed ulcers (class 5). One hundred and three patients (71%) underwent concomitant venous procedures (stripping, 70; high ligation, 17; varicosity avulsion alone, 16). There were no deaths or pulmonary embolisms. One deep venous thrombosis occurred at 2 months. The follow-up periods averaged 24 months (range, 1 to 53 months). Cumulative ulcer healing at 1 year was 88% (median time to healing, 54 days). Concomitant ablation of superficial reflux and lack of deep venous obstruction predicted ulcer healing (P <.05). Clinical score improved from 8.93 to 3.98 at the last follow-up (P <. 0001). Cumulative ulcer recurrence at 1 year was 16% and at 2 years was 28% (standard error, < 10%). Post-thrombotic limbs had a higher 2-year cumulative recurrence rate (46%) than did those limbs with primary valvular incompetence (20%; P <.05). Twenty-eight of the 122 patients (23%) who had class 5 or class 6 ulcers before surgery had an active ulcer at the last follow-up examination. CONCLUSIONS: The interruption of perforators with ablation of superficial reflux is effective in decreasing the symptoms of chronic venous insufficiency and rapidly healing ulcers. Recurrence or new ulcer development, however, is still significant, particularly in post-thrombotic limbs. The reevaluation of the indications for SEPS is warranted because operations in patients without previous deep vein thrombosis are successful but operations in those patients with deep vein thrombosis are less successful. Operations on patients with deep vein occlusion have poor outcomes.  (+info)

Popliteal artery occlusion as a late complication of liquid acrylate embolization for cerebral vascular malformation. (8/1721)

Occlusion of arteriovenous malformations of the brain (BAVMs) by means of an endovascular approach with liquid acrylate glue is an established treatment modality. The specific hazards of this procedure are related to the central nervous system. In the case of unexpectedly rapid polymerization of the cyanoacrylate glue and adhesion of the delivering microcatheter to the BAVM, severing the catheter at the site of vascular access is considered an acceptable and safe management. We present a unique complication related to this technique that has not been described yet. Fragmentation and migration of the microcatheter, originally left in place, had caused popliteal artery occlusion, which required saphenous vein interposition, in a 25-year-old man. Suggestions for avoiding this complication are discussed.  (+info)

Coronary artery bypass graft (CABG) surgery is a commonly used revascularization strategy in patients with severe coronary artery disease. Saphenous vein grafts (SVGs) are the most frequently used conduits for this procedure. Unlike arterial grafts, SVGs are particularly susceptible to occlusive thrombosis during the first post-operative year, which exposes patients to increased risks of death, myocardial infarction, and repeat revascularization.. This study is designed to evaluate the effect of antiplatelets (Tirafiban and Prasugrel) on the incidence of early and intermediate graft patency after CABG. Patients will undergo planned cardiac Computed tomographic angiography (CTA) predischarge (at 1 week) and CTA/coronary angiography (CAG) at 6 months to 1 year follow-up. CTA at baseline (predischarge) and follow-up CTA/CAG at 6-12 months after CABG will be used to evaluate graft patency. ...
Percutaneous coronary intervention of degenerated saphenous vein grafts remains relatively high risk when compared to native vessel interventions, despite advances in pharmacotherapy and embolic protection. This article discusses the phenomenon of distal embolization that seems to plague saphenous vein graft interventions, reviews device-based strategies for embolic protection, and offers a perspective on the utility of percutaneous saphenous vein graft intervention in both elective and acute settings.. ...
Primary human endothelial cells have a finite life span in vitro. After 3-4 passages, they tend to de-differentiate and eventually reach senescence. This limits their use in studies of endothelial cell function. To overcome this, we have developed human saphenous vein endothelial cell lines (HSVEC lines). Two cell lines were produced by infection with pZipSVtsA58-U19 which encodes the simian virus 40 large T-antigen, and one cell line was obtained by transfection with pLXSN16E6E7, which encodes the human papillomavirus type 16 E6 and E7 genes. Two of the three HSVEC lines exhibited an extended life span in vitro and retained characteristic endothelial cobblestone morphology. These cell lines expressed the known endothelial markers CD31 and vascular endothelial cadherin, and were able to bind Ulex europaeus lectin I, but they did not retain the expression of von Willebrand factor. Furthermore, one cell line was able to functionally up-regulate the expression of intercellular adhesion molecule-1 ...
Objective: The saphenous vein is the most commonly used graft in coronary artery bypass surgery, since no suitable arterial graft is available. However, the frequency of late graft failure is a cause for research into graft protection. The objective of this study was to investigate the effect of synthetic adhesive cyanoacrylate administration on the saphenous vein graft for preventing vascular damage due to internal pressure on the graft. Methods: In this study we enrolled 20 volunteer subjects who had undergone coronary artery bypass surgery and who had excess saphenous vein grafts. Perivascular cyanoacrylate was administered to one of two saphenous vein grafts explanted from each patient. The other saphenous vein graft from each patient was not treated and was used as the control. A model of the arterial system was created using a saphenous vein cardiopulmonary bypass system. Circulation was maintained at 120 mmHg for 45 minutes. Afterwards, the grafts were subjected to histopathological examination.

The ubiquity of coronary artery disease and the resultant widespread use of saphenous veins for coronary artery bypass surgery has stimulated considerable interest in the morphologic and pathophysiologic alterations these vessels undergo after implantation. This study was undertaken to determine the ability of intravascular ultrasound to identify and characterize abnormalities in saphenous vein grafts. Ten saphenous vein grafts excised at autopsy and nine saphenous vein segments harvested during coronary artery bypass surgery were examined with intravascular ultrasound imaging, quantitative coronary angiographic techniques and histologic analysis.. Intravascular ultrasound lumen measurements were strongly correlated with quantitative coronary arteriographic measurements (r 0.91, SEE 0.5 mm). Wall thickness was significantly greater in the vein grafts after long-term implantation than in the freshly harvested veins (average thickness 1.4 ± 0.5 vs. 0.7 ± 0.2 mm, p , 0.007); this finding ...

Autologous saphenous vein continues to be one of the most widely used conduits for myocardial revascularization7 despite its disappointing long-term patency rate, with ≤50% of vein grafts occluded by 10 years after surgery.8 9 Late occlusion appears to result from both medial and neointimal thickening, caused by migration and proliferation of smooth muscle cells, and the late appearance of mature lipid-laden atherosclerotic plaques. These changes can compromise flow directly or promote thrombotic occlusion.1 10 Neither antiplatelet therapy nor avoidance of surgical preparative injury has been shown conclusively to eliminate medial and neointimal thickening in either experimental models or human vein grafts.1 2 8 Vessel wall thickening may be regarded as an intrinsic adaptation of the vein to arterial pressure,1 10 and grafting per se was recently shown to stimulate the production of endogenous growth factors from pig saphenous vein, which may account for the platelet independence of graft wall ...

In this study we investigated to find out one of the best preparation technique by the effect of different solutions on venous morphology for harvested saphenous vein graft for CABG. Saphenous veins harvested from 10 patients were divided into three groups, and saphenous veins were divided to 3 cm segments. Group I was the control group and saphenous vein graft was enlarged by 20 mmHg, in Group II saphenous vein graft put in isotonic sodium chloride for 20 minutes and enlarged by 100 mmHg, and Group III saphenous vein graft was put in nitroprusside for 20 minutes and enlarged by 100 mmHg pressure. All saphenous vein segments were examined under light microscope for endothelial cell deprivation, intimal and medial edema and scored from 0 to 3. Mean scores were collected as datas. In nitroprusside group all scoring datas were better. As a result we found out that nitroprusside was having better protective effect on saphenous vein endothelium ...

N2 - Background Inferior lower extremity bypass (LEB) outcomes have been reported among women with peripheral arterial disease (PAD), but the mechanisms responsible for this disparity are unknown. Great saphenous vein (GSV) is considered the conduit of choice for LEB; GSV diameter is associated with graft patency and therefore is often used as a criterion for suitability for use as bypass conduit. We hypothesized that gender-based differences in GSV may contribute to LEB outcomes disparities. To explore this hypothesis, we performed a gender-based analysis of GSV anatomic characteristics among patients with PAD who ...

There are multiple treatment options for varicose veins. While the initial treatment is medical consisting of compression stockings and medications, new products are ever evolving. One of the newest products available is the venaseal closure system for great saphenous veins. This treatment option does not require the postoperative use of compression stockings and has no risk of heat induced complications.. The venaseal closure system for great saphenous veins is a unique treatment option that uses a bioglue to obstruct and close the great saphenous vein. Traditional radiofrequency ablation can cause skin necrosis and has the potential to damage cutaneous nerves. The venaseal closure system for great saphenous veins does not use any heat. The surgeon will localize the vein using ultrasound. Then, the surgeon will insert the catheter into the vein. The catheter is manipulated to the proximal part of the vein and injected with the bioglue. The surgeon will gradually pull back on the catheter while ...
Within 6 h, shear stress upregulated intercellular adhesion molecule-1 (ICAM-1) (two- to four-fold, P|0.001) and induced matrix metalloproteinase-2 (MMP-2) in cultured human saphenous vein endothelial cells. By 8 h endothelial ICAM-1 levels returned to baseline, with concomitant increase in soluble ICAM-1 (sICAM-1) (P|0.001) and MMP-9 had been induced. Inclusion of a hydroxamate metalloproteinase inhibitor partially reversed the effects on ICAM-1 and sICAM-1 at 8 h, whereas TIMP-1, -2 or -3 had no effect. MMP-9, but not MMP-2, co-immunoprecipitated with ICAM-1. sICAM-1 was processed distal to Arg441, indicating that MMP-9, docking to ICAM-1, contributes to sICAM-1 shedding and attenuation of the shear stress-induced upregulation of ICAM-1.

BACKGROUND: Externally stenting saphenous vein grafts reduces intimal hyperplasia, improves lumen uniformity and reduces oscillatory shear stress 1 year following surgery. The present study is the first to present the longer-term (4.5 years) performance and biomechanical effects of externally stented saphenous vein grafts. METHODS: Thirty patients previously implanted with the VEST external stent in the randomized, within-patient-controlled VEST I study were followed up for adverse events; 21 of these were available to undergo coronary angiography and intravascular ultrasound. RESULTS: Twenty-one stented and 29 nonstented saphenous vein grafts were evaluated by angiography and ultrasound at 4.5 ± 0.3 years. Vein graft failure rates were comparable between stented and nonstented grafts (30 and 23% respectively; p = 0.42). All failures were apparent at 1 year except for one additional nonstented failure at 4.5 years. In patent vein grafts, Fitzgibbon perfect patency remained significantly higher in the
Aneurysmatic degeneration of saphenous vein coronary artery grafts is a rare complication that generally appears late. Most of these cases are asymptomatic, although they may also be accompanied by angina, heart attack or dyspnea. The suspected diagnosis should be made when a mediastinal mass is discovered in the thoracic x-ray of a patient with a history of coronary revascularization. A computerized tomography and coronary angiography should be performed in order to confirm the diagnosis.. Due to the significant morbidity and mortality risk inherent to the risk of rupture, embolization or heart attack, surgery to remove or exclude the aneurysm should be considered as definitive treatment.. ...
Coronary artery bypass grafting is an effective treatment for myocardial ischaemia and is particularly important in patients with multivessel disease and diabetes. However, up to 40% of saphenous vein grafts will occlude within 10 years of surgery. T
The great saphenous vein (GSV), also long saphenous vein, is the large (subcutaneous) superficial vein of the leg and thigh. The GSV originates from where the dorsal vein of the first digit (the large toe) merges with the dorsal venous arch of the foot. After passing anterior to the medial malleolus (where it often can be visualized and palpated), it runs up the medial side of the leg. At the knee, it runs over the posterior border of the medial epicondyle of the femur bone. The great saphenous vein then courses laterally to lie on the anterior surface of the thigh before entering an opening in the fascia lata called the saphenous opening. It joins with the femoral vein in the region of the femoral triangle at the saphenofemoral junction ...

A 73 year old woman presented with angina 22 years after saphenous vein grafts. All three grafts were in excellent condition, with the exception of a severe stenosis in the proximal portion of the circumflex graft (panel A). For elective percutaneous coronary intervention (PCI), a FilterWire distal protection device was deployed in the body of the graft before pre-dilatation with a 2.5 × 15 mm Maverick balloon. Aiming to minimise the risk of distal embolisation, a (self expanding nitinol) Symbiot polymer covered stent (4.0 × 20 mm) was deployed (panel B). These stents require post-inflation to optimise deployment. Following in-stent inflation (4.0 × 15 mm Extensor) a new filling defect (white arrow) was immediately apparent within the stent at its proximal end (panel C). Filling defects (white arrows) were also present within the FilterWire device (black arrows) (panel C). The in-stent debris was presumed to be material extruded from the proximal margin of the covered stent after high ...
The main trunk of the long saphenous vein arises from the medial marginal vein, anteriorly to the medial malleolus. It ascends vertically behind the medial border of the tibia, then behind the medial condyle of the femur to reach the femoral vein below the inguinal ligament.. In addition to the anatomical variants of its junction with the femoral vein, the long saphenous vein is also characterized by the complexity of its accessory and satellite networks.. It is essential to remember that a dilated long saphenous vein, with reflux at the saphenofemoral junction and upper third of the thigh, may be associated with a small (2 mm), competent trunk in the mid-thigh. This vessel, sometimes not detected on ultrasonography, preserves its normal anatomical course along the aponeurosis in the lower third of the thigh, as the reflux persists in an anterior or posterior accessory saphenous yein (Figure 66 left), or an accessory vein parallel to the main trunk (Figure 66 right).. When the accessory vein is ...

Background Saphenous vein grafts develop an aggressive atherosclerotic process and the efficacy of drug eluting stents (DES) in treating saphenous vein graft (SVG) lesions has not been convincingly demonstrated. The aim of this study was to review and analyze the current literature for controlled studies comparing DES versus bare metal stents (BMS) for treatment of SVG stenoses. Methodology/Principal Findings We searched several scientific databases and conference proceedings up to March 15, 2010 for controlled studies comparing target vessel revascularization (TVR) between DES and BMS. Summary odds ratios (OR) for the primary endpoint TVR and secondary endpoints infarction, stent thrombosis and death were calculated using random-effect models. A total of 29 studies (3 randomized controlled trials RCT) involving 7549 (202 in RCT) patients were included. The need for target vessel revascularization in the DES group tended to be lower compared to BMS for the 3 RCT (OR 0.50 [0.24-1.00]; p = 0.051) and for
Fifty-five consecutive patients with intermittent resting chest pain persisting more than 24 hours after hospitalization and accompanied by ECG changes representative of ischemia were operated urgently more than one year ago. Recent cases with shorter follow-up are excluded. Twenty-eight patients had single grafts, 23 had double grafts, three had triple grafts, and one a quadruple graft. There were three operative deaths (5%) and one sudden late death (2%). There were six early Mls and three late Mls. Follow-up ranges from 12 to 52 months (mean 24 months) with nine patients followed for four years. Actuarial analysis indicates a projected survival rate of 93% three years postoperative. Twenty-three survivors are Functional Class (FC) I, 19 are FC II, and eight are FC III. Functional class could not be determined in one survivor. Thirty patients had postoperative angiography one week to 32 months postop. 35/51 grafts were patent. Only three patients had no patent grafts. There were no significant ...

OBJECTIVES: Early saphenous vein graft (SVG) occlusion is typically attributed to technical factors. We aimed at exploring clinical, anatomical, and operative factors associated with the risk of early SVG occlusion (within 12 months postsurgery). METHODS: Published literature in MEDLINE was searched for studies reporting the incidence of early SVG occlusion. Individual patient data (IPD) on early SVG occlusion were used from the SAFINOUS-CABG Consortium. A derivation (n = 1492 patients) and validation (n = 372 patients) cohort were used for model training (with 10-fold cross-validation) and external validation respectively. RESULTS: In aggregate data meta-analysis (48 studies, 41,530 SVGs) the pooled estimate for early SVG occlusion was 11%. The developed IPD model for early SVG occlusion, which included clinical, anatomical, and operative characteristics (age, sex, dyslipidemia, diabetes mellitus, smoking, serum creatinine, endoscopic vein harvesting, use of complex grafts, grafted target vessel, and

Providing the interface between the blood and the underlying layers of smooth muscle, the endothelium is the guardian of the vessel wall. Dejana et al26 were the first to describe the specific binding of fibrinogen to the endothelium. Since then, there have been numerous reports that particular sequences on the fibrinogen molecule, or its fragments, can interact with cultured endothelial cells and result in a variety of downstream events. In particular, the cleavage of fibrinopeptide B to expose the Bβ15-42 sequence at the amino terminals of the Bβ chains has been considered to mediate the release of von Willebrand factor, endothelial cell spreading, and proliferation on fibrin.14 27 28 Very recently, VE-cadherin has been identified as the endothelial cell receptor for the Bβ15-42 sequence of fibrin.16 The present study indicates that interaction of the Bβ15-42 sequence of fibrinogen with endothelial cells cultured from human saphenous vein leads to the upregulation of ICAM-1 and increased ...

Background: Endoscopic vein harvest (EVH) was introduced in 1996 as an alternative to open vein harvest (OVH) for coronary artery bypass graft (CABG) surgeries utilizing the saphenous vein. EVH has been shown to decrease post operative pain, wound complications, and length of hospital stay. Although EVH has become the preferred method of saphenous vein harvest, the effect of EVH on graft patency has not been well studied. A study published in the New England Journal of Medicine in 2009 concluded that EVH was independently linked to increased morbidity and decreased graft patency. This surprising conclusion was not endorsed by the cardiothoracic community. Much debate about the effect of EVH on graft patency has ensued, however, surgical practice appears to have remained unchanged. The potential harm of EVH must be weighed against its proven benefits in the light of the large number of patients that undergo EVH annually as the predominant mode of saphenous vein harvest Methods: An exhaustive literature
Importance: Observational studies have suggested that the use of radial artery grafts for coronary artery bypass grafting may improve clinical outcomes compared with the use of saphenous vein grafts, but this has not been confirmed in randomized trials.. Objective: To compare clinical outcomes between patients receiving radial artery vs saphenous vein grafts for coronary artery bypass grafting after long-term follow-up.. Design, Setting, and Participants: Patient-level pooled analysis comparing radial artery vs saphenous vein graft in adult patients undergoing isolated coronary artery bypass grafting from 5 countries (Australia, Italy, Serbia, South Korea, and the United Kingdom), with enrollment from 1997 to 2009 and follow-up completed in 2019.. Interventions: Patients were randomized to undergo either radial artery (n = 534) or saphenous vein (n = 502) grafts for coronary artery bypass grafting.. Main Outcomes and Measures: The primary outcome was a composite of death, myocardial infarction, ...

The saphenous vein, which runs from the ankle to the groin along the inside of the leg, is commonly used as a graft for people undergoing a CABG surgery. The vein is removed from the leg and reattached to the heart to create a detour around the blocked part of a coronary artery. Following this procedure, many people are prescribed aspirin as a way to increase the chance that the graft procedure will be successful. However, saphenous vein graft failure may still occur in some people, indicating a need to understand why this happens and who might be at risk for graft failure. Thrombin, a protein involved in the blood clotting process, is somehow related to aspirin resistance, abnormalities in blood flow, and cell disruption within the saphenous vein, all factors thought to increase the risk of graft failure. The purpose of this study is to evaluate the likelihood that a burst in thrombin contributes to graft failure in people who have recently undergone a CABG procedure using the saphenous ...
Endovenous Laser Treatment (EVLT®), also known as laser vein ablation, is a minimally-invasive procedure used to treat the great saphenous vein (GSV), small saphenous vein (SSV) and other superficial veins. It uses laser energy applied inside the faulty (or incompetent) vein to seal it shut. The EVLT procedure has been FDA-approved since 2002 and over 100,000 procedures have been performed. Endovenous laser treatment (EVLT) is commonly performed in a physicians office, under local anesthesia, in less than an hour, generally with rapid return to normal activity. Other names for laser vein ablation include endovenous laser ablation of the saphenous vein (ELAS or ELA), endovenous laser therapy (ELT), and endovenous laser vein system (ELVeS).

1. We investigated the potentiating effect of low concentrations of neuropeptide Y (NPY) on the vasoconstriction induced by transmural nerve stimulation (TNS) and noradrenaline (NA) in human saphenous veins. The effects of (i) endothelium removal; (ii) the addition of the NO pathway precursor L-arginine; (iii) the ET(A)/ET(B) endothelin receptor antagonist Ro 47-0203; (iv) the cyclo-oxygenase inhibitor, indomethacin; (v) the selective thromboxane A2 (TxA2) receptor antagonists Bay u3405 and ifetroban, and (vi) the TxA2 synthase inhibitor, UK 38485, were studied in order to gain information about the mechanisms of NPY-induced potentiation. 2. Contractile response curves for TNS (0.5-8 Hz) and for exogenously administered NA (0.1-3 microM) were obtained in superfused saphenous vein rings. The contractions induced by both TNS and NA at all tested frequencies and concentrations, respectively, were significantly potentiated by 50 nM NPY in endothelium intact veins. Conversely, in endothelium-denuded vessel

Technique Summary Resources and references Saphenous vein sampling in other animals All blood sampling techniques in the guinea pig Please read the general principles of blood sampling page before attempting any blood sampling procedure. Technique Sampling from the lateral saphenous vein is a relatively quick method of obtaining blood samples from all strains of guinea pig. It does not require the animal to be warmed. Slides and videos of restraint, shaving and sampling for this technique with mice are available on the websites of the Norwegian Reference Centre for Laboratory Animal Science. Blood is collected from the lateral saphenous vein, which runs dorsally and then laterally over the tarsal joint. Conscious guinea pigs should be restrained either manually or using a restraint tube. This can cause stress and therefore the duration of restraint should be minimised. Where a restraint tube is used, it should be appropriate for the size of the guinea pig. All forms of restraining equipment should be
More than 50% of aortocoronary saphenous vein grafts are occluded 10 years after surgery. Intimal hyperplasia is the initial critical step in the progression toward occlusion. Internal mammary veins, which are physiologically prone to less hydrostatic pressure, may undergo an accelerated progression to intimal hyperplasia and thus be suitable for investigation of the mechanisms of aortocoronary vein graft disease. Six minipigs underwent aortocoronary bypass grafting using standard cardiopulmonary bypass and cardioplegic arrest. Mammary vein were grafted in a reversed manner from ascending aorta to left anterior descending coronary artery (LAD). The proximal LAD was ligated, rendering the anterior left ventricle vein graft-dependent. Minipigs were killed after 4 weeks, and vein grafts were harvested. Histological and immunohistological investigation were performed with respect to morphometric analysis, endothelial damage/dysfunction (v-Willebrand-factor (vWF)), smooth muscle cells (α-smooth actin) and
Background. According to previously published studies, the most frequent localization of vascular lesions responsible for recurrent varicose vein (RVV) development is a previously ligated saphenofemoral junction (SFJ) site. Discovering the background of these lesions would allow the implementation of suitable methods to reduce their incidence and thus RVV development. Material and methods. We examined 240 patients (283 limbs) with RVV after classic surgical treatment of primary lower limb varicose veins. The reasons for varicose vein recurrence were determined with duplex ultrasound examination. Results. Faults of the surgical technique and neovascularization were causes for true recurrence of varicose veins (TRVV) in 87.6% of all limbs with RVV. Incompletely extirpated great saphenous veins (GSV) or small saphenous veins (SSV) were discovered in 25.1% of cases. Stumps with SFJ or SPJ tributaries were found in 76.3% of limbs. Persistent tributaries were present on stumps in 68.5% of cases, ...
Memorial Medical Center (Springfield, IL) Medical Imaging Services Saphenous vein ablation is used to treat venous insufficiency in the leg by ablating the vein using thermal energy.
Are your veins becoming abnormally large? Do they look twisted? If you are experiencing these symptoms on your legs or any other parts of your body, there is a high chance you might have varicose veins. Varicose veins occur when your blood valves leak and creates a pool of blood in your leg veins. As a result, your veins will start to swell up. Many people will experience discomfort or aches in the region, as the vein continues to enlarge and starts to get inflamed. When the symptoms get severe, it is advised to consult your local vein clinic for treatment.. With modern advancements in the medical field, there are now efficient varicose vein treatments that are non-invasive and safe. One of the most effective procedures for treating varicose veins is Endovenous ablation. Endovenous ablation is an image-guided procedure that takes advantage of ultrasound technology to help close the affected vein. This procedure is minimally invasive and is generally safe to perform. However, unlike other ...

Endovenous laser varicose vein surgery is a procedure that uses heat from a laser to reduce varicose veins. Varicose veins are swollen, bulging veins that often happen on the thighs or calves. A laser is a device that sends a thin beam of radiation in the form of light.
HistoryA 48-year-old man underwent three-vessel aortocoronary bypass graft for unstable angina and high-grade occlusive coronary artery disease. Postoperatively
form of light.. Laser surgery closes and shrinks the varicose vein and causes scar tissue within the vessel. This seals off the vein. Blood then flows through other nearby veins instead.. Your healthcare provider may suggest laser surgery if your varicose veins are sore, or red and swollen (inflamed). Laser surgery may also be recommended if the skin over your varicose veins is irritated.. Varicose veins are not usually a serious health problem, but they can be painful. You may also not like how they look.. All surgeries have some risks. Some possible risks of laser varicose vein surgery include: ...
Historical Background By the 1890s Trendelenburg not only had developed the compression test to evaluate saphenous vein reflux but also had performed great saphenous vein ligations using a transverse upper thigh incision, thus establishing the foundation for surgical treatment of varicose veins. In 1916 Homans described ligation of the saphenofemoral junction as it is commonly…
Despite the apparent superiority of arterial conduits for coronary artery bypass grafting (CABG), the long saphenous vein remains the most commonly used graft. The high failure rate of long saphenous vein grafts (SVGs) over time is therefore an important limiting factor for the long-term outcomes of CABG. Various methods to improve SVG patency have been proposed, although few have had a significant impact on clinical practice. External SVG supports have been a focus of research over the past 50 years, with their use intended to minimize well-documented pathophysiological changes that occur in the SVG following implantation into the coronary circulation. These devices have been trialled extensively in animal models to assess their impact on both the morphology and the function of vascular conduits. Recently, a number of studies have been conducted in patients, leading to a substantial development in their design and the accumulation of a large body of evidence attesting to their potential benefit in CABG
Szabo and colleagues evaluated the effectiveness of EVRF treatment and analysed the three-year results of using the device for endovenous radiofrequency ablation and spider vein treatments from July 2011 to March 2015 to treat 751 saphenous reflux and varicosity patients.. Radiofrequency ablation using the EVRF CR45i catheter was performed on 751 limbs (628 greater saphenous vein, 102 small saphenous vein and 21 for both). Complete occlusion was found in 743 of 751 cases (99%) at one month. At one-year follow-up, 15 of 530 patients showed recanalisation longer than 5cm (97.2% one-year occlusion) without clinical symptoms. The three-year occlusion rate was 96.6% (two of 59 patients had an open vein segment). At one-year follow-up the investigators evaluated the postoperative pain reported by the patients on a visual analogue scale (2.4 preoperatively, 1.2, 0.4 and 0.1 at one week, one month and one year postoperatively, respectively) and Venous Clinical Severity Scores (7.7, 3.9 and 1.8 before ...

N2 - Background: Interleukin-8 (IL-8) secreted from endothelial cells is a powerful neutrophil chemoattractant and activator. We hypothesized that human endothelial cells deprived of oxygen would secrete IL-8, which might translate into elevated IL-8 production after cardiac ischemia. Furthermore, we hypothesized that coronary sinus (CS) IL-8 levels would be particularly high after cardiac preservation for transplantation, due to extended ischemic times. Methods and Results: Human saphenous vein endothelial cells exposed to a hypoxic environment (PO2 ,20 mm Hg) demonstrated a time-dependent release of IL-8 (measured by ELISA) into the culture supernatant as ...
A high intake of the omega-3 fatty acid docosahexaenoate [docosahexaenoic acid (DHA)] has been associated with systemic antiinflammatory effects and cardiovascular protection. Cyclooxygenase (COX)-2 is responsible for the overproduction of prostaglandins (PG) at inflammatory sites, and its expression is increased in atheroma. We studied the effects of DHA on COX-2 expression and activity in human saphenous vein endothelial cells challenged with proinflammatory stimuli. A ≥24-h exposure to DHA reduced COX-2 expression and activity induced by IL-1, without affecting COX-1 expression. DHA effect depended on the NF-κB-binding site in the COX-2 promoter. EMSAs confirmed that DHA attenuated NF-κB activation. Because MAPK, PKC, and NAD(P)H oxidase all participate in IL-1-mediated COX-2 expression, we also tested whether these enzymes were involved in DHA effects. Western blots showed that DHA blocked nuclear p65 NF-κB subunit translocation by decreasing cytokine-stimulated reactive oxygen species ...

Varicose veins are a common cosmetic concern that most frequently affect the legs. In some cases, varicose veins also cause discomfort or pain. If you suffer from varicose veins, there are a variety of non-invasive vein therapy options available to eliminate them and restore your confidence in the appearance of your legs.. Causes of Varicose Veins. Varicose veins occur when the one-way valves inside the veins malfunction or wear out. When these valves do not function properly, blood pools inside the vein rather than being transported up the legs to the heart. Pooling blood causes the vein to expand and turn dark red, blue, or purple, forming a varicose vein. In many cases, the valves simply wear out due to age. However, there are other factors that contribute to the formation of varicose veins. Being overweight and minimally-active puts excess strain on your cardiovascular system, affecting the veins and their valves. Pregnancy can also cause the formation of varicose veins. Varicose veins are ...

We present the case of a 58-year-old man who presented to our wound care centre with a 7 -month history of a progressive unilateral leg ulcer. He reported intermittent, heavy bleeding at the ulcer. The duplex sonography showed a bilateral incompetence of the saphenofemoral junctions and the entire course of the great saphenous veins and, surprisingly, also a bilateral reversed arterial-like pulsating flow in the great and small saphenous veins as well as in the deep veins of the lower extremities. During cardiac examination by auscultation and echocardiography, we detected a previously undescribed severe tricuspid insufficiency with strongly reduced systolic ejection of both the left and the right ventricle and repercussions on the peripheral venous system as a cause for the pulsating veins ...
