Ultrasound guided sclerotherapy combined with sapheno-femoral ligation was less expensive, involved a shorter treatment time and resulted in more rapid recovery compared to sapheno-femoral ligation, saphenous stripping and phlebectomies.
In most patients, ultrasound-guided foam sclerotherapy is a safe treatment for recurrent varicose veins, with an excellent immediate result. However, the presence of proximal reflux may decrease the immediate results and predispose to superficial thrombophlebitis.
Aims: We evaluated long‐term impact of iliofemoral thrombosis (IFDVT) on walking capacity, venous haemodynamics, CEAP class, venous‐clinical‐severity score (VCSS) and quality of life (SF‐36), and determined prevalence of venous claudication.
Methods: All patients with prior IFDVT at our institution since 1990 were followed up. Excluded were those with walking impairment due to arterial (ABI < 1.0 post‐exercise) or unrelated causes, and those thrombectomized or thrombolyzed. Thirty‐nine patients (22–83 years) were included. Median follow‐up was 5 years (range: 1–23). Investigation included CEAP and VCSS stratification, air‐plethysmography (outflow fraction: OF; venous‐filling index: VFI; residual‐volume fraction: RVF), duplex, treadmill (3.5 km h−1, 10 per cent) to determine initial (ICD) and absolute (ACD) claudication distances, and SF‐36 assessment. Non‐affected limbs of patients with unilateral IFDVT (37/39) comprised the control group; data presented as median and interquartile range.
Results: A total of 75.6 per cent of limbs with IFDVT had superficial and deep reflux and 26.3 per cent superficial reflux; reflux in control limbs was 13.5 and 19 per cent, respectively (P < 0.01); 43.6 per cent (17/39) (95 per cent CI: 27–60 per cent) of patients developed venous claudication ipsilateral to IFDVT (ICD: 130 (105–268) m), compelling 15.4 per cent (6/39) (95 per cent CI: 3.5–27 per cent) to discontinue treadmill (ACD: 241 (137–298) m). Limbs with prior IFDVT had a lower OF (37 (32.2–43) per cent; P < 0.001), abnormally higher VFI (3.8 (2.5–5.7) mL s−1; P < 0.001) and RVF (45 (32.5–51.5) per cent; P = 0.006), and clinical impairment in CEAP and VCSS (P < 0.0001). Patients with IFDVT had impaired physical functioning and role (P < 0.034), general health (P < 0.001), social function (P = 0.047) and mental health (P = 0.043).
Conclusions: Of those with prior IFDVT 43.6 per cent developed venous claudication, compelling interruption of walking in 15.4 per cent; prior IFDVT caused outflow impairment, and large residual‐venous volume and reflux, resulting in marked clinical and quality‐of‐life compromise. Standardized challenge enabled discrimination of those with clinically relevant impairment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
