Long-term clinical observations and venous functional abnormalities after asymptomatic venous thrombosis following total hip or knee arthroplasty

The long-term clinical and physiological sequelae of venographically diagnosed, asymptomatic postoperative venous thrombosis were studied in a group of 51 patients following total hip or total knee arthroplasty. After a mean follow-up period of 49.7 months, the patients were recalled for interview, physical examination, air plethysmography (APG), and photoplethysmography (PPG). At the time of follow-up examination, legs with prior postoperative venous thrombosis were not more likely to have clinical findings of deep venous insufficiency than legs with a negative venogram. Abnormal venous emptying, as measured by APG, was significantly correlated (p less than 0.005) with postoperative venous thrombosis and was found in patients with both proximal and calf vein thrombi, but was not clearly associated with symptoms. There was, however, a significant correlation (p less than 0.0005) between clinical findings of venous insufficiency and incompetent valves, as reflected by rapid refilling time after exercise shown by PPG. The findings indicate that asymptomatic postoperative venous thrombosis involving calf or proximal veins can lead to abnormal vein function, but is not closely correlated with later development of symptoms. These observations also suggest that symptomatic venous insufficiency is more closely associated with calf vein valve incompetence than with proximal vein obstruction.     

A novel approach: ascending venous arterialization for atherosclerosis obliterans.

OBJECTIVE: Lower limb arterial occlusion with no patent distal artery suitable for revascularisation is a common problem. The aim of this study was to assess the role of revascularisation to distal veins (ascending venous arterialization) in patients not reconstructable by conventional bypass. METHOD: Ascending venous arterialization is a distal arteriovenous fistula. Reversed great saphenous vein grafts, from above the knee, were anastomosed to the common femoral artery, superficial femoral artery or popliteal artery and distally to the saphenous vein at the level of medial malleolus. No intervention was done to destroy the venous valves. The great saphenous vein was ligated below the knee. In this way, oxygenated blood could reach to dorsal venous arch and the tissues below the knee in an ascending fashion through the great saphenous vein, which was not removed. RESULTS: All of the patients recovered immediately after the operation. The lesions on the feet and on the toes of the patients improved in a short time. Intermittent claudication of the patients disappeared. Strong pulses were detected on the dorsal venous arch with manual Doppler in 3 weeks. The below knee tissues were perfused with the applied technique. CONCLUSION: Ascending venous arterialization can be applied for limb salvage to the patients who do not have a suitable arterial bed to revascularize with conventional techniques.     

The influence of elastic compression stockings on deep venous hemodynamics.

To determine the effect of elastic compression stockings on deep venous hemodynamics we measured ambulatory venous pressure, venous refill time, maximum venous pressure with exercise, amplitude of venous pressure excursion, and duplex-derived common femoral and popliteal vein diameter and peak flow velocities with and without stockings in 10 healthy subjects and 16 patients with chronic deep venous insufficiency. The effects of below-knee and above-knee 30 to 40 torr and 40 to 50 torr gradient stockings were studied. Despite documentation of substantial stocking compressive effects by skin pressure measurements, neither below-knee or above-knee elastic compression stockings significantly improved ambulatory venous pressure, venous refill time, maximum venous pressure with exercise, or the amplitude of venous pressure excursion in healthy patients or in patients with deep venous insufficiency (p greater than 0.05). In patients with deep venous insufficiency stockings modestly increased popliteal vein diameter and flow velocity in the upright resting position (p less than 0.02). After tiptoe exercise without stockings deep venous peak flow velocity increased in healthy patients and in patients with deep venous insufficiency by a mean of 103% in the popliteal vein and 46% in the common femoral vein (p less than 0.01). With the application of elastic compression stockings only modest augmentation of deep venous flow velocity occurred in both groups above that seen in the bare leg after exercise. Thus elastic compression stockings did not improve deep venous hemodynamic measurements in patients with deep venous insufficiency. The beneficial effects of stockings in the treatment of deep venous insufficiency must relate to effects other than changes in deep venous hemodynamics.     

Patterns of venous insufficiency after an acute deep vein thrombosis

BACKGROUND: The purpose of this study was to investigate patterns of venous insufficiency during a 12-month period after an acute deep vein thrombosis. STUDY DESIGN: Seventy limbs in 67 patients with an acute deep vein thrombosis (DVT) involving 147 anatomic segments were evaluated with duplex scanning at 1 month, 3 months, 6 months, and 1 year. Venous segments were examined whether they were occluded, partially recanalized, or totally recanalized, and the development of venous reflux was evaluated. RESULTS: The segments investigated were the common femoral vein (38 segments), femoral vein (33 segments), popliteal vein (36 segments), and calf veins (40 segments). There were 35 limbs with isolated DVT and the remaining 35 had multisegment DVT. At 1 year, thrombi had fully resolved in 76% of the segments, 20% remained partially recanalized, and 5% were occluded. The venous occlusion was most predominant in the femoral vein (21%) at 1 year. On the contrary, rapid recanalization was obtained in calf veins than in proximal veins at each examination (p < 0.01). Deep vein insufficiency was detected as early as 1 month after development of DVT, and the reflux was most predominant in popliteal veins (56%), followed by femoral veins (18%). No reflux was found in calf veins. Multisegment DVTs had a significantly higher incidence of deep vein insufficiency than single segment DVTs at 1 year. Development of superficial venous insufficiency was found in 5 limbs (7%) and perforating vein insufficiency in 5 (7%). CONCLUSIONS: Lower extremity venous segments showed different proportions of occlusion, partial recanalization, and total recanalization. Calf veins showed more rapid recanalization than proximal veins. Venous reflux was noted as early as 1 month. The limbs involving multisegment DVTs on initial examination had a higher incidence of deep vein insufficiency and could require much longer followup studies.     

Surgery of the superficial venous system in elderly patients

Chronic venous insufficiency, which traditionally has been attributed to failure of the deep venous system, may result from reflux in the superficial venous system. Chronic venous insufficiency is common in elderly patients, but surgical treatment is seldom offered to this patient population. We evaluated the results of superficial venous surgery for the treatment of severe chronic venous insufficiency in a cohort of elderly patients. The authors assessed patients aged 70 years or more with chronic venous insufficiency that had failed conventional conservative treatment. The superficial and deep venous systems were thoroughly investigated by duplex ultrasonography. Associated medical conditions were reevaluated and their treatment optimized. Twenty-eight patients (11 men, 17 women), aged between 70 and 89 years (mean 79), underwent superficial venous surgery. Open ulcers, active dermatitis and recurrent erysipelas were evident in 12, 9 and 7 patients, respectively. Limb swelling and severe pain were present in 25 (89%). The operations were performed under general or regional anesthesia with overnight hospitalization. Surgical treatment consisted of ligation of the points of reflux at the junctions of the superficial and deep systems, as defined by the duplex examination (21 saphenofemoral junctions, 5 saphenopopliteal junctions, 10 perforator veins), and stripping of the long saphenous vein to knee level (15 patients). Postoperative ambulatory treatment was continued until the wounds were completely closed. All ulcers healed completely within 8 weeks. No cardiac, respiratory, or renal complications were encountered. Wound infection at the groin occurred in 1 patient. Cellulitis of the calf area developed in 4 patients. Two ulcers recurred during follow-up of 1 to 5 years (mean 2.5). Surgery of the superficial venous system for treatment of severe chronic venous insufficiency is effective and can be achieved with minimal morbidity in selected elderly patients. The risk/benefit ratio for this procedure has been reduced sufficiently to ensure a major improvement in the quality of life of such patients.     

Revascularization of the limbs using vein grafts after vascular injuries

We report on 32 patients with vascular injury of a limb undergoing a total of 41 revascularization procedures with interposition vein grafts. A combined arterial and venous injury was present in nine cases, an isolated venous injury in four, and an isolated arterial injury in 19 cases. Eighteen per cent of patients with arterial injuries had normal distal pulses on initial examination. Preoperative arteriography was performed in 12 cases, and intraoperative arteriography in four. All venous injuries were diagnosed at operation. In most cases, the contralateral greater saphenous vein was used for grafting. Four patients had postoperative thrombosis after arterial reconstruction resulting in below knee amputation in two cases. Two patients suffered from postoperative swelling caused by venous insufficiency, one after ligation of an injured axillary vein, and the other one following venous thrombosis of a superficial femoral vein repair. It is concluded that revascularization of arterial and venous injuries of the extremities with interposition vein grafts is successful in most cases resulting in low amputation rates, and should be attempted in all major vascular injuries in viable limbs.     

Reverse venous outflow of a free fibular osteocutaneous flap: a salvage procedure.

The authors report 2 patients with a massive bony defect of the tibia due to chronic osteomyelitis. They reconstructed the defect using a free vascularized fibular osteocutaneous flap. Unfortunately, venous insufficiency was diagnosed 24 hours postoperatively. The previous anastomosed veins were promptly explored. The peroneal veins of the vascularized fibular bone graft were noted to be full of thrombi. After thrombectomy, the vessels became very fragile and broke down easily. It was impossible to achieve normal antegrade venous outflow from the previous vein of the donor graft; however, they found that distal runoff of the peroneal vein achieved a reverse venous outflow from the donor graft. The great saphenous vein was dissected and reanastomosed to achieve adequate venous drainage. This procedure may offer an alternative treatment for a flap with venous insufficiency.     

Der Stellenwert der autologen Klappentransplantation in der Behandlung der chronisch venösen Insuffizienz im Rahmen des postthrombotischen Syndroms

Although deep vein thrombosis now has a better prognosis than in the era before anticoagulation, a number of patients remain in whom ulcus cruris cannot be adequately controlled by conservative treatment. The case report of a 50-year-old woman with stage III chronic venous insufficiency associated with the post-thrombotic syndrome is presented. Progress in imaging techniques and functional diagnostics of the post-thrombotic syndrome make a reliable differentiation of the chronic venous insufficiency possible with respect to obstruction or reflux. If conservative treatment fails, autological valve transplantation is described as a suitable reconstructive management method in the treatment of reflux. Following this report, the results and limitations of this method are discussed.     

Treatment of incompetent vein of Giacomini (thigh extension branch)

Most varices secondary to truncal insufficiency arise from the greater saphenous vein (GSV), short saphenous vein (SSV), or accessory saphenous branch. However, an important etiology for varices that arise on the posterior thigh or calf is often overlooked. The thigh extension (TE) branch, also known as the vein of Giacomini in many patients, may also contribute to venous pathology. Patients were assigned to one of three categories depending on the anatomical findings. All patients were treated with a combination of endovenous ablation using a 940 nm Skin Pulse S laser and foam sclerotherapy. Eighteen patients were treated and followed for at least 2 years. There were no complications. All patients had successful ablation of the TE branch with successful obliteration of any perforators or collateral vessels. Varices secondary to TE branch insufficiency are common when coexisting SSV insufficiency is present. The incidence increases when both SSV insufficiency and GSV insufficiency exist. This study groups the pattern of TE branch pathology into three anatomical patterns. Combination therapy based on the prevalent anatomical group being treated was done. There was successful ablation in all groups with no complications. As experience in venous disease and expertise by the surgeon increases, more examples of this pattern of pathology will become evident.     

Correction of lower extremity deep venous incompetence by ablation of superficial venous reflux

Chronic venous insufficiency which produces lipodermatosclerosis, varicosities, or ulceration, is frequently caused by superficial venous reflux and deep venous incompetence. The anatomy of venous insufficiency has been clarified with duplex ultrasound, thus allowing appropriately directed therapy. However, postoperative venous physiology in patients undergoing superficial venous ablation has been infrequently reported. This study was undertaken to document the effect of superficial venous ablation on deep venous reflux. Between April 1994 and May 1995, 45 patients were examined preoperatively with duplex ultrasound. All patients had symptomatic venous insufficiency and were found to have greater saphenous vein reflux. Clinical classification of venous insufficiency (according to the criteria of the joint councils of the vascular societies) included class I in 30 patients, class II in 12, and class III in 3. Seventeen patients (38%) had reflux in the femoral venous system in addition to superficial reflux. All patients underwent removal of the proximal greater saphenous vein in concert with multiple stab avulsions of identified varicosities. Postoperative interrogation of the venous system revealed that in 16 (94%) of 17 patients, coexistent femoral venous insufficiency completely resolved. Thus ablation of superficial venous reflux eliminated incompetence in the deep venous system in patients with combined disease. These preliminary results suggest that superficial venous incompetence may be a cause of deep venous insufficiency. Whereas alternative methods to correct deep venous insufficiency have met with limited success, it appears that saphenectomy (when combined disease is present) may be effective in correction of deep venous reflux.Presented at the Twentieth Annual Meeting of the Peripheral Vascular Surgery Society, New Orleans, La., June 10, 1995.     

B-cell lymphoma related iliac vein occlusion treated by endovenous stent placement

Unilateral leg swelling is most often caused by deep vein thrombosis but other conditions may mimic this disorder. We describe the case of a patient with symptoms of unilateral lower extremity swelling caused by external compression of the iliac vein by a mass originating from the iliopsoas muscle. Initially this mass was diagnosed as an iliopsoas hematoma in a patient using anticoagulants. However, it proved to be B-cell non-Hodgkin lymphoma. Compression was relieved by placement of an endovenous stent in the left common iliac vein. Endovenous stenting is a relatively new treatment modality that is used to treat post-thrombotic venous occlusions and chronic venous insufficiency. Only a few case series have been described of stenting of compressed pelvic veins by adjacent structures such as gynecological malignancies. Although stent patency lasted only four weeks in this patient, venous stent placement quickly reliefs symptoms and should therefore be considered as an option to bridge time to allow development of sufficient venous collaterals.     

Radiofrequency Ablation and Laser Ablation in the Treatment of Varicose Veins

Chronic venous insufficiency is a major medical disease in the United States. With a total population of 300 million, it is estimated that 25 million persons in this country alone have symptoms of this disease (1 in 12). Great saphenous vein reflux is the most common form of venous insufficiency in symptomatic patients and is most frequently responsible for varicose veins of the lower extremity. Therefore, therapy directed toward correcting superficial venous pathology is beneficial to many patients.     

Radiofrequency ablation of the long saphenous vein without high ligation versus high ligation and stripping for primary varicose veins: pros and cons

Primary varicose vein disease is prevalent in our society, and although it is infrequently the cause of serious venous insufficiency, it often is associated with symptoms of local discomfort. These symptoms eventually may outweigh any cosmetic concerns of patients with this disease. Greater saphenous vein (GSV) reflux is the most important pathophysiologic component of primary venous insufficiency. To date, the surgical treatment of GSV reflux has evolved into 1 of 3 procedures: high ligation of the saphenofemoral junction, with or without perforator ligation; high ligation and stripping of the GSV; and high ligation with retrograde sclerotherapy of the GSV. High ligation and stripping of the GSV to below the knee enjoys the most durable success yet is associated with significant perioperative morbidity. A new treatment, radiofrequency ablation of the GSV without high ligation, recently has been described and promises a less invasive alternative to stripping with decreased morbidity and increased patient acceptance. The results of high ligation and stripping of the GSV will be compared with those with radiofrequency ablation of the GSV without high ligation.     

Use of Ipsilateral Greater Saphenous Vein as a Valved Transplant in Management of Post-Thrombotic Deep Venous Insufficiency: Long-Term Results

Incompetence of the deep venous valve is a common feature of post-thrombotic deep venous insufficiency. Various surgical techniques have been proposed to treat reflux. In this study we describe long-term results of a novel transposition technique using the ipsilateral greater saphenous vein. From 1984 to 1994 we used this procedure to treat 16 patients including 10 men and 6 women with a mean age of 56 years (range: 25 to 76 years). In all 16 cases the indication for surgery was incapacitating pain associated with recurring ulceration in 9 patients. From the results of using this technique we conclude that transposition using the ipsilateral greater saphenous vein is safe and effective with good mid-term results, especially for pain. For ulcers the primary success rate was 55% but this increased to 84% with proper surveillance and treatment of secondary insufficiency of the superficial venous system.     

Deep axial reflux, an important contributor to skin changes or ulcer in chronic venous disease

OBJECTIVE: We undertook this cross-sectional study to investigate the distribution of venous reflux and effect of axial reflux in superficial and deep veins and to determine the clinical value of quantifying peak reverse flow velocity and reflux time in limbs with chronic venous disease. PATIENTS AND METHODS: Four hundred one legs (127 with skin changes, 274 without skin changes) in 272 patients were examined with duplex ultrasound scanning, and peak reverse flow velocity and reflux time were measured. Both parameters were graded on a scale of 0 to 4. The sum of reverse flow scores was calculated from seven venous segments, three in superficial veins (great saphenous vein at saphenofemoral junction, great saphenous vein below knee, small saphenous vein) and four in deep veins (common femoral vein, femoral vein, deep femoral vein, popliteal vein). Axial reflux was defined as reflux in the great saphenous vein above and below the knee or in the femoral vein to the popliteal vein below the knee. Reflux parameters and presence or absence of axial reflux in superficial or deep veins were correlated with prevalence of skin changes or ulcer (CEAP class 4-6). RESULTS: The most common anatomic presentation was incompetence in all three systems (superficial, deep, perforator; 46%) or in superficial or perforator veins (28%). Isolated reflux in one system only was rare (15%; superficial, 28 legs; deep, 14 legs; perforator, 18 legs). Deep venous incompetence was present in 244 legs (61%). If common femoral vein reflux was excluded, prevalence of deep venous incompetence was 52%. The cause, according to findings at duplex ultrasound scanning, was primary in 302 legs (75%) and secondary in 99 legs (25%). Presence of axial deep venous reflux increased significantly with prevalence of skin changes or ulcer (C4-C6; odds ratio [OR], 2.7; 95% confidence interval [CI], 1.56-4.67). Of 110 extremities with incompetent popliteal vein, 81 legs had even femoral vein reflux, with significantly more skin changes or ulcer, compared with 29 legs with popliteal reflux alone (P =.025). Legs with skin changes or ulcer had significantly higher total peak reverse flow velocity (P =.006), but the difference for total reflux time did not reach significance (P =.084) compared with legs without skin changes. In contrast, presence of axial reflux in superficial veins did not increase prevalence of skin changes (OR, 0.73; 95% CI, 0.44-1.2). Incompetent perforator veins were observed as often in patients with no skin changes (C0-C3, 215 of 274, 78%) as in patients with skin changes (C4-C6, 106 of 127, 83%; P =.25). CONCLUSION: Continuous axial deep venous reflux is a major contributor to increased prevalence of skin changes or ulcer in patients with chronic venous disease compared with segmental deep venous reflux above or below the knee only. The total peak reverse flow velocity score is significantly higher in patients with skin changes or ulcer. It is questionable whether peak reverse flow velocity and reflux time can be used to quantify venous reflux; however, if they are used, peak reverse flow velocity seems to reflect venous malfunction more appropriately.     

Deep vein thrombosis after elective knee surgery. An incidence study in 312 patients

The incidence of venous thromboembolism after elective knee surgery has previously been studied almost exclusively in patients receiving total knee replacements, in whom the risk of a deep vein thrombosis is approximately 60%. We report the results of ipsilateral ascending venography in 312 patients undergoing a wide variety of elective knee operations under tourniquet ischaemia, none of whom received any specific prophylaxis against thromboembolism. Total knee replacement was confirmed to carry a high risk with ipsilateral deep vein thrombosis in 56.4% and symptomatic pulmonary embolism in 1.9%. By contrast, arthroscopy was associated with a low incidence of venous thrombosis (4.2%). Meniscectomy, arthrotomy, patellectomy, synovectomy and arthrodesis were all high-risk procedures, particularly in patients over 40 years of age, and were associated with deep vein thrombosis rates of 25% to 67%. On the basis of these findings, we advise prophylaxis against venous thromboembolism in all patients over 40 years of age undergoing elective knee surgery other than arthroscopy.     

Correlation of clinical findings with venous hemodynamics in 386 patients with chronic venous insufficiency

Deep venous insufficiency secondary to deep valvular incompetence predominated over superficial venous insufficiency in an unselected patient population with advanced chronic venous insufficiency. Venous obstruction was uncommon (5 percent), suggesting that venous bypass surgery may have limited applicability in the management of chronic venous insufficiency. Although the majority of patients (72 percent) with stage III venous disease (ulcer) had deep venous insufficiency alone and would be potential candidates for deep valvular reconstruction, 13 percent were found to have superficial venous insufficiency alone, and the remaining 15 percent, deep venous insufficiency with a hemodynamically significant component of superficial venous insufficiency. These findings suggest that not all patients with stage III disease have altered hemodynamics on the basis of deep venous valvular incompetency. Although most stage III chronic venous insufficiency is secondary to altered deep venous hemodynamics, as demonstrated by shortened venous refill time, there is a significant group of patients with severe chronic venous insufficiency having superficial venous insufficiency alone or in combination with deep venous insufficiency (28 percent). Thus, it is imperative that those patients with superficial venous insufficiency be identified by a widely available and reproducible method, such as light reflection rheography, since they may respond to surgery of the superficial venous system alone.     

Popliteal vein entrapment: a benign venographic feature or a pathologic entity?

PURPOSE: Asymptomatic morphologic popliteal vein entrapment is frequently found in the healthy population (27%). In our institution, popliteal vein compression on plantar flexion was observed in 42% of all ascending venograms. Some authorities consider the lesion benign, without pathologic significance. This study examines the pathophysiologic importance in select patients, describes treatment with surgery, and suggests a diagnostic tool. METHOD: Thirty severely symptomatic patients with venographic evidence of popliteal entrapment were selected to have popliteal vein release after a process of elimination (ie, other causes of chronic venous insufficiency [CVI] were ruled out by means of comprehensive hemodynamic and morphologic studies). In the last nine limbs, popliteal vein pressure was also measured by means of the introduction of a 2F transducer tip catheter. Patients were clinically and hemodynamically assessed before and after surgery, and anatomical anomalies encountered during surgery were recorded. RESULTS: Popliteal vein release was performed without mortality or serious morbidity. Anomalies of the medial head of the gastrocnemius muscle caused entrapment in 60% of the patients; anatomic course venous anomalies were infrequent (7% of the patients). Significant relief of pain and swelling occurred in the patients who had surgery. Stasis ulceration/dermatitis resolved in 82% of patients. Popliteal venous pressures had normalized in the six patients who were studied postoperatively. CONCLUSION: Popliteal vein entrapment should be included in the differential diagnosis of CVI in patients in whom other, more common etiologies have been excluded on the basis of comprehensive investigations. Popliteal vein compression can be demonstrated venographically in a large proportion of patients with CVI, but the lesion is likely pathological only in a small fraction of these patients. A technique for popliteal venous pressure measurement is described; it shows promise as a test for functional assessment of entrapment. Immediate results of popliteal vein release surgery are encouraging; long-term follow-up is necessary to judge the efficacy of surgical lysis of entrapment in symptomatic patients who fail to improve with conservative treatment measures.
