RESUMEN
OBJECTIVES: Comparison of Reverse Foam Sclerotherapy of the great saphenous vein (GSV) combed with sapheno-femoral junction (SFJ) ligation to standard (Babcock) stripping and invagination (Pin) stripping in a prospective clinical series. DESIGN: Prospective clinical series. MATERIALS AND METHODS: 90 consecutive limbs of 82 patients with incompetence of the GSV resulting in varicose veins were prospectively randomised into 3 groups of 30, treated by SFJ ligation and either reverse foam sclerotherapy, standard stripping or invagination stripping of the GSV. Outcomes were assessed post-operatively and at 2-weeks follow-up. Peri-operative blood loss (24 hrs), analgesic requirement, bruising and residual varicosities were assessed. Bruising was assessed by both patients and independent assessors using questionnaires. RESULTS: SFJ ligation plus reverse foam sclerotherapy of the GSV was associated with significantly less blood loss, bruising and post-op discomfort than either of the stripping techniques. (p<0.001, Mann-Whitney) CONCLUSION: Standard stripping of the GSV and invagination stripping are not associated with major discomfort and problems in the early post-operative period. SFJ ligation and GSV reverse foam sclerotherapy yielded greater patient satisfaction with less post-op bruising and discomfort and reduced analgesic requirements.

AIM: The aim of this study was to assess the effect of a specialised Vascular Unit upon the prevalence of ruptured aortic aneurysms in the same population catchments' area and associated mortality rates. SETTING: prospective computerised data collection from 1997 to today, retrospective from 1990-1996. SUBJECTS: 108 aneurysms were operated upon from 1990-1996, compared to 317 from 1997 to Aug 2002. MAIN OUTCOME MEASURES: statistical analysis was done using SPSS statistics with Kaplan Meier life table curves and compared by the log rank test while the Mann Whitney test was used for comparison of mortality. RESULTS: The median values for ruptured aneurysms per year were 5 for the early period, compared to 10 for the recent years, while the median values for both urgent and ruptured were 7 and 18.5 cases annually, respectively. The number of scheduled procedures increased by 500% in the second period, with median values of 7 and 36.5, respectively. In-hospital mortality according to category was 21% for scheduled, 31% for urgent and 69% for ruptured aneurysms in the early period, compared to 3.7%, 16% and 29% respectively, following the establishment of the Vascular Unit. CONCLUSION: Despite the five-fold increase in the total number of aortic aneurysm repairs (as expected), the number of ruptured aneurysms operated upon increased as well. There was just a trend for a reduction in the absolute numbers of ruptured aneurysms operated upon in the last 2 years. Mortality, on the other hand, decreased dramatically in all categories, with the overall 30-day mortality decreasing more than four-fold, from 40% to 9.3%, while the respective mortalities according to the category of intervention were 3.7% vs 21% for scheduled, 16% vs 35% for urgent and 29% vs 69% for ruptured aneurysms, with a P value of less than 0.01. However, there was no difference in the numbers of patients with ruptured aneurysm reaching the hospital (operated or not) between the two periods (median values of 11 and 10.5 annually). The presence of a Vascular Unit, although it achieves dramatically better results, is not associated with a reduction in the number of emergency proceduresaeat least in the intermediate termaedespite an expansion in the indications for surgery, increased awareness and prompt referrals (centralisation).

AIM: To investigate the anatomic distribution of vein reflux in limbs with healed or active ulcers (CEAP V and VI). METHODS: Sixty limbs (58 patients) belonging to CEAP classes V and VI were identified from 798 limbs (519 patients) with ultrasonically proven chronic venous insufficiency (CVI). Age, gender, duration of the venous ulcer, and history of deep venous thrombosis were correlated to the anatomic distribution of the venous reflux. RESULTS: The prevalence of active or healed ulcers in limbs with CVI was 7.5%. Among 60 limbs with ulcers, primary CVI was present in 34 (56.7%) and post-thrombotic CVI in 26 limbs (43.3%). No difference in age and gender was found between the 2 groups (p=0.2 and p=0.8, respectively). However, the duration of the ulcer was longer in limbs with post-thrombotic CVI (p<0.05). The prevalence of perforator reflux was 41.2% (14/34) in limbs with primary CVI and 38.5% (10/26) in limbs with post-thrombotic CVI (p=0.8). Superficial venous insufficiency, with or without perforating vein reflux, was the commonest pattern in limbs with primary CVI; it was rare in limbs with post-thrombotic CVI (22/34 or 64.7% vs 2/26 or 7.7%, p<0.01). Deep vein insufficiency was present in 35.3% (12/34) of the limbs with primary CVI and in 92.3% (24/26) of the limbs with post-thrombotic CVI (p<0.01). CONCLUSION: Superficial venous insufficiency, with or without perforating vein reflux, was the commonest pattern in limbs with primary CVI, whereas, deep venous insufficiency was present in most of the limbs with post-thrombotic CVI. The prevalence of perforating vein reflux was comparable in both settings. Thus, elimination of superficial reflux is expected to result in ulcer healing of most limbs with primary CVI, whereas, the value of such treatment in post-thrombotic limbs is not clear.
