Abstract
Chronic leg ulceration is a major cause of morbidity in homozygous sickle cell (SS) disease in Jamaica. These ulcers have features in common with venous ulcers in patients with a normal haemoglobin genotype (AA). Thus we sought to determine whether there is abnormal venous function in the legs of patients with SS disease who have ulcers. Experiments were performed on 15 SS patients with ulcers, and on 15 SS patients and 15 AA subjects with no history of leg ulcers. Changes in venous blood volume of the bottom one-third of the leg induced by venous occlusion and release were studied by air plethysmography, providing indices of segmental venous capacitance (SVC), maximal venous outflow (MVO) and venous emptying time (VET). The changes in volume (ambulatory volume change; AVC) induced by a period of leg exercise were also measured at the ankle (AVCa) and calf (AVCc); venous refilling times at these sites (RTa and RTc respectively) were also measured. Finally, cutaneous red blood cell flux recovery time (FRT) after ankle exercise was assessed by laser Doppler flowmetry. Measurements were also made of haematological variables. SVC, MVO and VET did not differ between the groups, indicating no deep venous obstruction in the SS patients with ulcers. AVCc, AVCa and RTc did not differ among the three subject groups. However, compared with AA subjects, SS patients with ulcers had reduced RTa and FRT. Moreover, RTa and FRT were further shortened in SS patients with ulcers relative to SS patients without ulcers. Since the levels of anaemia were similar in SS patients with and without ulcers, these differences cannot be attributed to differences in arterial flow secondary to anaemia. These results suggest abnormal venous function in SS patients with ulcers, relative to both AA subjects and SS patients without ulcers. We propose that there is incompetence of venous valves draining the ankle region of SS patients with ulcers: the consequent raised venous pressure contributes to the slow healing and, possibly, to the onset of leg ulceration in SS disease.

Abstract
BACKGROUND The aim of the study is to investigate the development of subjective and objective findings during the first two years after DVT (deep venous thrombosis). METHODS This prospective two-year follow-up study was established in Tampere University Hospital in Finland. Twenty-six patients with a two-year follow-up after a phlebographically confirmed DVT were followed. Patients were treated conventionally with heparin and warfarin. Phlebography was repeated 7 months after DVT. Color-flow duplex imaging (CFDI) was performed in both legs 7 and 20 months after DVT. The subjective symptoms in both legs were recorded at the beginning and at the end of the follow-up. The development of venous reflux, obstruction and subjective symptoms after DVT were studied. RESULTS 50% of the legs with DVT had a pathological (deep reflux or obstructive change) CFDI-finding in the popliteal segment after a 20-month follow-up. The pathological findings in the control legs were rare. The rate of recanalisation was high. There was no difference between calf and more proximal DVTs. Pain (62%), oedema (46%) and pigmentation (35%) were common and only 27% of the legs with DVT were asymptomatic. CONCLUSIONS The development of the post-thrombotic syndrome begins quite early. The frequency of the subjective symptoms is high. Calf DVT may lead to postthrombotic sequelae in the popliteal segment.

Abstract
Treatment of venous and lymphatic insufficiency of the lower limbs is based on 3 components: elastic support, venotonic drugs and radical treatments (surgery or sclerotherapy) of insufficient veins. Venotonic drugs have specific indications limited to functional impairment: heavy feeling in the legs, pain and impatience in the evening. There are different categories of venolymphatic drugs. Flavonoids have various pharmacological actions, most notably an increase in venous tone, reduction of capillary permeability and increase of capillary resistance. Choice of a venotonic drug is funded on knowledge of pharmacodynamics and pharmacokinetics of the molecule, critical evaluation of clinical studies, physician's personal experience and drug cost. Venotonic drugs are useful when venous insufficiency leads to functional manifestations. They are especially the treatment of heavy leg syndromes during warm seasons when elastic support is uncomfortable.

Abstract
Painful sensation of heavy or swollen legs are non-specific symptoms frequently associated with chronic venous insufficiency. Clinical evaluation is the first step in defining the cause of the complaint and offering adequate treatment. When a heavy or swollen leg is associated with oedema, venous insufficiency, lymphatic or systemic disease must be considered. If symptoms occur during walking a vascular or nervous disease must be suspected. Associated erythema suggests infection (erysipelas). If clinical data are the cornerstone of diagnosis, difficulty may arise from the high frequency of superficial venous insufficiency and the readiness of linking too quickly any non specific complaint to this particular venous disease.

Abstract
BACKGROUND A chronic exertional compartment syndrome has only been observed in athletes and soldiers. In the vast majority, the disease affects the anterior compartment and the fibular muscle group, and only rarely the lateral and dorsal muscle compartments. Muscle tissue necrosis does not occur. In the course of venous diseases with a severe chronic venous stasis syndrome, a chronic venous compartment syndrome develops that differs considerably from the familiar functional syndrome. The predominant symptom is an uncurable cuff ulceration on the lower leg. PATIENTS AND METHODS From 1993 to 1996 a total of 16 patients with a chronic fascial compression syndrome underwent surgery on 18 extremities. The crural fascia was resected and a mesh graft was applied. RESULTS In the group of ten controls with healthy veins the average pressure in the deep compartment was 13.6 mmHg (range 9-17 mmHg) lying down and 29.9 mmHg (range 15-42 mmHg) standing up. In 14 patients with chronic fascial compression syndrome, the average pressure was higher, measuring 21.1 mmHg (range 8-47 mmHg) lying down and 62.5 mmHg (range 33-87) standing up. After surgery, the pressure dropped to 15.5 mmHg (range 5-24 mmHg) lying down and 34.5 mmHg (range 10-58 mmHg) standing up, but did not fall as low as the average values recorded in the control group or in the patient's healthy leg. The results from the standing up position were statistically significant (p = 0.003). Computed tomography showed major changes in the muscles indicating muscle atrophy and fatty degeneration. The crural fascia seemed to be incorporated in the scars of the subcutaneous tissue in large areas. After crural fasciectomy and healing of the ulceration, the tissue structure of the muscles recovered. CONCLUSIONS In chronic fascial compression syndrome, the trellis arrangement of the collagen fibres becomes disordered. This results in a loss of flexibility during muscle contraction. Every step causes an increase of intracompartmental pressure and microstructural injury. The consequence is resection of the crural fascia.

Abstract
The purpose of the present study was to evaluate the relationship between calf muscle pump dysfunction (CMD) and the presence and location of valvular incompetence. Deep vein obstruction might influence CMD, and so venous outflow resistance (VOR) was measured. VOR and calf muscle pump function were measured in 81 patients, 7-13 years after venographically confirmed lower-extremity deep venous thrombosis. The supine venous pump function test (SVPT) measures CMD, and the VOR measures the presence of venous outflow obstructions, both with the use of strain-gauge plethysmography. Valvular incompetence was measured using duplex scanning in 16 vein segments of one leg. Venous reflux was measured in proximal veins using the Valsalva manoeuvre, and in the distal veins by distal manual compression with sudden release. Abnormal proximal venous reflux was defined as a reflux time of more than 1 s, and abnormal distal venous reflux as a reflux time of more than 0.5 s. No statistically significant relationship was found between the SVPT and either the location or the number of vein segments with reflux. Of the 81 patients, only nine still had an abnormally high VOR, and this VOR showed no relationship with the SVPT. In conclusion, venous reflux has a limited effect on CMD, as measured by the SVPT. The presence of a venous outflow obstruction did not significantly influence the SVPT. Duplex scanning and the SVPT are independent complementary tests for evaluating chronic venous insufficiency.

Abstract
Advanced practice nurses caring for patients with venous disease may not be aware of the patient's understanding of illness, including the disease process, treatment, or outcomes. The advanced practice nurse uses his or her interpretation of illness to teach patients. Greater congruence between the nurse's and patient's understanding may result in enhanced communication, learning, and adherence. Exploration of the patient's reality may provide insight into a unique view of illness that may or may not be congruent with the biomedical model of disease. The current investigation attempts to identify an explanatory model of illness for chronic venous disease, by using the researcher-developed Diseases of Veins Explanation Survey. Data from a nonprobability sample of 114 primarily white, rural Midwestern, well-educated patients with medically confirmed and patient-acknowledged venous disease was collected at 7 sites. Twelve (10.5%) patients were men and 102 (89.5%) were women. Age range was 18 to 81 years. The factor analysis is presented. Elements of illness according to Kleinman (factors) did not fit within Kleinman's explanatory model of illness categories identified a priori in the instrument.

Abstract
PURPOSE To evaluate the role of intercellular adhesion molecule 1 (ICAM-1) in cutaneous leukocyte trapping in venous disease, we used our rodent model of venous hypertension (VH). MATERIALS AND METHODS VH was created in adult rats by ligation of the inferior vena cava, bilateral common iliac veins, and bilateral common femoral veins. In the Phase I experimental (exptl) group, anti-ICAM-1 monoclonal antibody (1A29) was given intravenously prior to venous ligations. Acute venous pressures were measured in the exptl and control (ctrl) (ligation only) groups. Bilateral forelimb and hindlimb skin specimens were harvested for myeloperoxidase (MPO) assay. In Phase II, VH was created in a chronic group; in a sham-operated group, ties were placed around the same vessels without ligations. Two weeks later, venous pressures were measured and radiolabeled ((125)I and (131)I) monoclonal antibody (mAb) to ICAM-1 was injected and allowed to circulate for 5 min before the level of radiolabeled antibody within forelimb and hindlimb specimens was measured. RESULTS In the acute study with 1A29, hindlimb pressures were significantly elevated in both the ctrl (n = 4) and exptl (n = 4) hindlimbs (15.4 +/- 0.239 and 13.8 +/- 1.89 mm Hg, respectively) compared with ctrl and exptl forelimbs (1.38 +/- 0.554 and 1.50 +/- 0.612 mm Hg, respectively). However, MPO activity was significantly elevated in the hindlimbs of the ctrl group compared with the hindlimbs of the exptl animals (19.8 +/- 1.54 U vs 6.71 +/- 2.46 U). In the chronic VH rats (n = 5) given radiolabeled anti-ICAM-1 mAb, the hindlimb pressures (10.1 +/- 4.52 mm Hg) were significantly elevated (P < 0.05) compared with forelimb pressures (1 +/- 0.447 mm Hg) and compared with the forelimb and hindlimb pressures in the sham-operated animals (n = 4) (1.63 +/- 0.813 and 4.25 +/- 2.13 mm Hg, respectively). However, there was not a significant difference in the quantity of ICAM-1-hindlimb versus forelimb or chronic VH versus sham. CONCLUSIONS Anti-ICAM-1 mAb decreased MPO activity in hypertensive hindlimb skin, supporting the instrumental role of ICAM-1 in cutaneous leukocyte trapping. However, the constituent endothelial ICAM-1 is not elevated by VH.

Abstract
The aim of the present study was to assess the influence of venous and lymphatic congestion on lymph capillary pressure (LCP) in the skin of the foot dorsum of healthy volunteers and of patients with lymph edema. LCP was measured at the foot dorsum of 12 patients with lymph edema and 18 healthy volunteers using the servo-nulling technique. Glass micropipettes (7-9 microm) were inserted under microscopic control into lymphatic microvessels visualized by fluorescence microlymphography before and during venous congestion. Venous and lymphatic congestion was attained by cuff compression (50 mm Hg) at the thigh level. Simultaneously, the capillary filtration rate was measured using strain gauge plethysmography. The mean LCP in patients with lymph edema increased significantly (p < 0.05) during congestion (15.7 +/- 8.8 mm Hg) compared to the control value (12.2 +/- 8.9 mm Hg). The corresponding values of LCP in healthy volunteers were 4.3 +/- 2.6 mm Hg during congestion and 2.6 +/- 2.8 mm Hg during control conditions (p < 0.01). The mean increase in LCP in patients with lymph edema was 3.4 +/- 4.1 mm Hg, and 1.7 +/- 2.0 mm Hg in healthy volunteers (NS). The maximum spread of the lymph capillary network in patients increased from 13.9 +/- 6.8 mm before congestion to 18.8 +/- 8.2 mm during thigh compression (p < 0.05). No increase could be observed in healthy subjects. In summary, venous and lymphatic congestion by cuff compression at the thigh level results in a significant increase in LCP in healthy volunteers as well as in patients with lymph edema. The increased spread of the contrast medium in the superficial microlymphatics in lymph edema patients indicates a compensatory mechanism for lymphatic drainage during congestion of the veins and lymph collectors of the leg.

Abstract
Using morphometry with the following variational-statistical analysis the study of the structural reorganization of brain capillary bed in different model disturbances of intracranial venous circulation was performed. It was shown that in acute stage of venous congestion, obtained by different ways, capillary bed displayed reaction of one type, in chronic stage it was dependent on the level of the venous block. Integrative index of degrees of capillary bed blood supply is a value of its volume in 1 cubic millimeter brain parenchyma.

Abstract
BACKGROUND Measurement of foot venous pressure (FVP) is useful for evaluating chronic venous insufficiency (CVI) functionally, because CVI always causes venous hypertension. In the present study, the various FVP parameters were analysed according to the new classification of venous disorders based on clinical, aetiological, anatomical and pathophysiological data (the CEAP classification). METHODS During the past 7 years, a total of 257 legs in 196 consecutive patients with CVI have been studied. The following FVP parameters were assessed: the percentage decrease in pressure from rest with manual calf compression, the rate of increase of pressure during 4 s after compression (4SR) and the time to 50 per cent recovery of pressure (RT50) after release of compression. RESULTS The incidence of skin changes due to venous stasis increased as the percentage pressure drop and RT50 fell. In addition, a pressure drop of less than 72 per cent and an RT50 of less than 20 s could detect legs with skin changes with a sensitivity of 76 per cent and a specificity of 62 per cent. In legs with primary varicose veins, pressure drop, 4SR and RT50 values deteriorated in proportion to the severity of the associated deep venous reflux. CONCLUSION FVP parameters correlate well with the severity of clinical manifestations and venous reflux, and could be used quantitatively to evaluate the severity of CVI.

Abstract
The objective of this study was to compare different quantitation parameters of venous reflux by duplex scan in different venous disease manifestations. Duplex scan is a new modality to quantify venous reflux. Several studies propose different parameters. In addition, there is controversy about the importance of deep and superficial involvement in different disease manifestations. It is not clear whether there is an increased venous reflux associated with varied clinical stages. Venous conditions were classified in seven stages and their differences for several quantitation variables studied. Most quantitation variables, such as average and peak velocity, average and peak flow, and reflux volume disclosed significantly increased reflux from normal, pain only, and edema group to varicose vein, with or without edema, to lipodermatosclerosis and ulcer groups at every location in the lower extremity. Reflux time was not as consistent as other variables. Totalization of the results of every parameter for the whole extremity points to an increased reflux from pain only to edema and from lipodermatosclerosis to ulcer group. Chronic edema is not usually associated with increased venous reflux. The greater saphenous vein (superficial system) seems to be the main contributor to reflux in all stages of disease. Different quantitation methods of venous reflux are equivalent. Increased deep and superficial reflux and its totalization are associated with a more advanced disease stage. Reflux time may be the least useful variable. Chronic edema is frequently not associated with venous reflux. Greater saphenectomy may be the most useful intervention, even in the presence of deep vein reflux.

Abstract
PURPOSE The efficacy of prophylactic inferior vena cava filters in selected trauma patients at high risk has come into question in relation to risk/benefit assessment. To evaluate the usefulness of prophylactic inferior vena cava filters, we reviewed our experience and overall complication rate. METHODS From February 1991 to April 1998, the trauma registry identified 7333 admissions. One hundred eighty-seven prophylactic inferior vena cava filters were inserted. After the exclusion of 27 trauma-related deaths (none caused by thromboembolism), 160 patients were eligible for the study. The eligible patients were contacted and asked to complete a survey and return for a follow-up examination to include physical examination, Doppler scan study, vena cava duplex scanning, and fluoroscopic examination. The patients' hospital charts were reviewed in detail. The indications for prophylactic inferior vena cava filter insertion included prolonged immobilization with multiple injuries, closed head injury, pelvic fracture, spine fracture, multiple long bone fracture, and attending discretion. RESULTS Of the 160 eligible patients, 127 were men, the mean age was 40.3 years, and the mean injury severity score was 26.1. The mean day of insertion was hospital day 6. Seventy-five patients (47%) returned for evaluation, with a mean follow-up period of 19.4 months after implantation (range, 7 to 60 months). On survey, patients had leg swelling (n = 27), lower extremity numbness (n = 14), shortness of breath (n = 9), chest pain (n = 7), and skin changes (n = 4). All the survey symptoms appeared to be attributable to patient injuries and not related to prophylactic inferior vena cava filter. Physical examination results revealed edema (n = 12) and skin changes (n = 2). Ten Doppler scan studies had results that were suggestive of venous insufficiency, nine of which had histories of deep vein thrombosis. With duplex scanning, 93% (70 of 75) of the vena cavas were visualized, and all were patent. Only 52% (39 of 75) of the prophylactic inferior vena cava filters were visualized with duplex scanning. All the prophylactic inferior vena cava filters were visualized with fluoroscopy, with no evidence of filter migration. Of the total 187 patients, 24 (12.8%) had deep vein thrombosis develop after prophylactic inferior vena cava filter insertion, including 10 of 75 (13.3%) in the follow-up group, and one patient had a nonfatal pulmonary embolism despite filter placement. Filter insertion complications occurred in 1.6% (three of 187) of patients and included one groin hematoma, one arteriovenous fistula, and one misplacement in the common iliac vein. CONCLUSION This study's results show that prophylactic inferior vena cava filters can be placed safely with low morbidity and no attributable long-term disabilities. In this patient population with a high risk of pulmonary embolism, prophylactic inferior vena cava filters offered a 99.5% protection rate, with only one of 187 patients having a nonfatal pulmonary embolism.

Abstract
Sixty patients (mean age 73.5 years) with 88 leg ulcers that had not responded to conservative treatment had split skin grafts applied at the Department of Plastic Surgery, Linköping, Sweden. Of 51 venous leg ulcers 45 (88%) healed after a mean of 15 days (range 5-30); and 13 (62%) of the 21 arterial ulcers healed after a mean of 18 days (range 8-30). Additional skin grafting was done on nine of the venous and on three of the arterial ulcers. Twenty-two (49%) of the healed venous ulcers recurred after a mean of four months while only two (15%) of the healed arterial ulcers recurred after a mean of 10 months. At late follow up after a mean of four years 18 of the patients were dead and 10 had had the leg in question amputated. Of the 34 patients still alive who had not had amputations, 31 were investigated at open ward or interviewed by telephone and 23 patients were examined with colour duplex scan. Seven of these patients had open leg ulcers. At duplex scan six patients had no venous or arterial insufficiency that could cause a leg ulcer. Of 16 patients with venous insufficiency 10 patients had only an inadequate superficial system. The mean cost for treating one leg ulcer by skin grafting is estimated at SEK 89000 (US$11125). We conclude that leg ulcers often heal with skin grafting but that venous ulcers often recur. To reduce the recurrence rate we suggest a better preoperative aetiological evaluation and improved postoperative treatment with a compression bandage.

Abstract
Chronic venous insufficiency with venous hypertension causes leukocyte trapping, lipodermatosclerosis, and finally, skin ulceration involving the lower extremity. Perforator vein incompetence has been identified as an important contributing factor to ulceration when abnormally elevated pressure is transmitted to areas of affected skin, usually at the ankle medially. Surgical techniques for ligation of incompetent communication veins were first popularized by Linton and Dodd from 1940 to 1950. Early techniques used extensive longitudinal incisions for subfascial ligation through indurated skin. These procedures were plagued with wound complications: delayed healing, skin necrosis, and infection. Techniques continued to evolve that used minimally invasive incisions and avoided zones of affected skin. With the availability of endoscopic, fiberoptic, and laparoscopic advances in surgery, instrumentation has been developed for minimally invasive endoscopic approach to accomplish subfascia endoscopic perforator surgery (SEPS) under direct vision. SEPS is now used alone and in combination with other venous interventions to reduce transmission of venous hypertension to affected skin areas. The SEPS procedure, its indications, and the history of surgical treatment of perforator vein incompetence are discussed. Unique problems related to short hospital stays and postoperative care are outlined. This review will help the vascular nurse understand the rationale and techniques of SEPS. This comprehension will enable provision of accurate information to the patient and a knowledge-based plan of care.

Abstract
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.

Abstract
Chronic venous ulcer disease is often refractory to conservative treatment modalities. After surgery of the superficial vein system, endoscopic methods can be used for division of incompetent perforators or to perform paratibial fasciotomy in cases of chronic functional compartment syndromes. We report on 13 endoscopically performed paratibial fasciotomies with or without concomitant endoscopic subfascial division of perforators (ESDP) in patients with stasis ulcers present for a median duration of 15 years. In all patients we observed immediate reduction of pain and edema. In 8 of 13 cases the ulcers healed within 3 months, another ulcer healed within 6 months and the remaining 4 ulcers showed a reduction in size of more than 75%. We conclude that endoscopically performed fasciotomy with or without ESDP is highly effective and has its place in the treatment of chronic venous ulcer disease.
