Incidence of Stent Thrombosis after Endovascular Treatment of Iliofemoral or Caval Veins in Patients with the Postthrombotic Syndrome.
2019
Abstract Background Patients with postthrombotic syndrome (PTS) treated with stents are at risk of stent thrombosis (ST). The incidence of ST in the presence and absence of anticoagulation therapy (AT) is unknown. Risk factors are not well understood. Patients and Methods From the prospective Swiss Venous Stent registry, we conducted a subgroup analysis of 136 consecutive patients with PTS. Incidence of ST was estimated from duplex ultrasound or venography, and reported for the time on and off AT. Baseline, procedural, and follow-up data were evaluated to identify factors associated with ST. Results Median follow-up was 20 (interquartile range [IQR] 9–40) months. AT was stopped in 43 (32%) …
Spontaneous echo contrast caused by platelet and leukocyte aggregates?
2001
Background and Purpose —Spontaneous echocardiographic contrast (SEC) is correlated to clinical thromboembolic events. We sought to determine the origin of SEC by utilizing direct analysis of left atrial blood. Methods —We examined the blood of 13 patients with and 19 without SEC. Blood samples were taken from the femoral vein and artery and from the right and left atria after transseptal puncture. Samples were incubated with fluorescence-labeled antibodies directed against the platelet (CD41a-PE, CD42b-PE, and CD62p-FITC) and leukocyte membrane epitopes (CD45-APC and CD14-FITC). The expressed epitopes were analyzed by dual laser flow cytometry immediately after blood withdrawal. Results —I…
Optimal duration of treatment in surgical patients with calf venous thrombosis involving one or more veins.
2006
The aim of this study was to evaluate different durations of treatment in patients with calf venous thrombosis (CVT) involving 1 or more deep veins. The authors studied 2 groups of patients with postsurgical CVT diagnosed by echo-color Doppler. The first group consisted of 68 patients with CVT involving a single vein, and the second group consisted of 124 patients with CVT involving 2 or more veins. Immediately after diagnosis, all patients were treated with nadroparin calcium and sodium warfarin. Heparin treatment was withdrawn after 5–6 days of treatment, when the international normalized ratio (INR) was stabilized between 2 and 3. Each group was divided into 2 subgroups receiving antico…
[Inferior vena cava malformations and deep venous thrombosis].
2006
We carried out a prospective study of 116 patients under 50 years of age who had deep venous thrombosis of the lower extremities to determine whether the presence of congenital anomaly of the inferior vena cava (IVC) was a risk factor for the disease. All patients were investigated by Doppler echography. Some 37 patients who had iliac vein occlusion also underwent phlebography. In 10 patients in whom the IVC was difficult to image, magnetic resonance angiography or computerized axial tomography was carried out. In all patients, studies of antithrombin, protein C and protein S deficiency, factor V Leiden, prothrombin G20210A, antiphospholipid antibodies, and acquired risk factors were also p…
A longitudinal single-center cohort study on the prevalence and risk of accessory saphenous vein reflux after radiofrequency segmental thermal ablati…
2015
Objective Endothermal ablation has become a commonly used technology for occlusion of refluxing great saphenous veins (GSVs). However, the risk for primarily untreated accessory saphenous veins (ASVs) to develop reflux during follow-up has not yet been defined. Here, the prevalence and risk of ASV reflux is explored. Methods During a prospective multicenter cohort study on radiofrequency segmental thermal ablation of refluxing GSVs, the presence and reflux status of ASVs were monitored in 93 legs in a single center. Control examinations were performed after 1 week and at 12, 24, 36, and 48 months. Life-table and multiple regression analyses were used to describe frequency and risk factors f…
Paradoxical embolism after a femoral fracture
1998
The foramen ovale is anatomically open in 25 % of individuals, but functionally closed by the higher pressure in the left antrum. Right-to-left shunt and subsequent paradoxical embolism may occur when pressure in the left antrum rises, for example, as a result of pulmonary embolism. In the present case we demonstrate a patient who presented 20 days after osteosynthetic treatment of a femoral fracture with word-finding deficits. Cerebral MRT revealed a fresh ischemic insult. Duplex ultrasound of the legs showed a fresh thrombosis of the superficial femoral vein and scintigraphy of the lungs detected pulmonary embolism. Transesophageal contrast echocardiography trapped a hemodynamically spont…
Use and durability of femoral vein for autologous reconstruction with infection of the aortoiliofemoral axis.
2014
Objective To analyze early and late mortality, venous morbidity, reinfection, and freedom from reintervention after using the femoral vein (FV) for vascular reconstruction with infection of the aortoiliofemoral axis. Methods By reviewing our database, 86 patients could be identified with implantation of FV grafts in infected fields between November 1995 and July 2012. The patient records were retrospectively analyzed and follow-up information obtained from patients or their general physician. Seventy-one patients presented with prosthetic graft infection and 15 with an infected aneurysm. For data analysis, patients were divided into an aortoiliac (n = 67) and a femoral group (n = 19). Study…
Infrapopliteal Composite Bypass with Autologous Vein and Second Generation Glutaraldehyde Stabilized Human Umbilical Vein (HUV) for Critical Lower Li…
2007
Objective. To audit a single center consecutive series of infrapopliteal composite bypasses with second generation glutaraldehyde stabilized human umbilical vein. Design. Retrospective study. Patients. From January 1996 to July 2006 89 femoro-distal bypasses were constructed in 85 patients with HUV and residual vein segments as composite grafts in the absence of sufficient length of autologous vein. Methods. All patients with infrainguinal bypass operations were registered prospectively. Bypasses to infrapopliteal arteries performed with HUV-composite grafts were reviewed for graft patency, limb salvage, patient survival and possible biodegeneration of the HUV. Results. Early graft thrombos…
The DETOUR procedure: no more need for conventional bypass surgery?
2018
Background Long segment occlusive disease in the superficial femoral artery remains a treatment challenge despite advances in open surgical and endovascular approaches. We report initial clinical results of an entirely new procedure to perform percutaneous femoro-popliteal bypass using the DETOUR System. First-in-human patients were performed in New Zealand from December 2013 to June 2014. After modifications to the technique and devices had significantly refined the procedure, the Detour I Trial commenced. Methods Review of initial results in the first five patients treated at a single site enrolled in IRB-approved, prospective clinical study using the DETOUR System. All patients signed in…
Digital Subtraction Angiography in Staging Renal Cell Carcinoma: Comparison with Computerized Tomography and Hlstopathology
1984
Digital subtraction angiography was compared to computerized tomography and histopathological findings for staging renal cell carcinoma in 24 patients. Injection of contrast material through a 16 gauge angiocatheter into the femoral vein provided digital subtraction cavography, digital subtraction arteriography and excretory urography during 1 investigation. Computerized tomography established the diagnosis in all patients, while digital subtraction angiography showed all angiographic signs of renal cell carcinoma in 14 (58 per cent). T staging was correct on computerized tomography in 18 patients and on digital subtraction angiography in 16. Absence or presence of venous involvement was in…
