This group has previously reported that UK Asians are significantly less likely to undergo surgery for lower limb venous disease than age and sex matched Caucasians. The aim of the present study was to estimate the prevalence of lower limb chronic venous disease (CVD) in the UK Asian male population.
A prospective, epidemiological survey.
100 unselected Asian men attending a local Mosque were assessed for the evidence of lower limb CVD, involving the collection of data on history and clinical signs and objective assessments of venous pathophysiology using lower limb venous ultrasonography and venous photoplethysmography (PPG).
On clinical examination, 80 limbs (in 50 subjects) had clinical evidence of CVD, the majority of cases consisting of varicose veins (CEAP C2). No limbs had either healed or active ulceration (C5/6), and only 2 limbs had thread veins (C1). Eight subjects had had previous venous surgery. The venous refill time (vRT) measured by PPG was lower in limbs with CVD. On venous ultrasound, reflux was present in 73/200 limbs, affecting primarily the GSV system, with only 7 limbs having deep venous reflux.
Present data strongly suggest that the low rates of superficial venous surgery in UK Asians is not because they are inherently less likely to develop CVD.
该研究小组此前报告称，与年龄和性别匹配的白种人相比，英国亚裔因下肢静脉疾病接受手术的可能性要低得多。本研究的目的是估计英国亚裔男性人群中下肢慢性静脉疾病（CVD）的患病率。
一项前瞻性流行病学调查。
对100名到当地清真寺做礼拜的未经过挑选的亚洲男性进行下肢CVD评估，包括收集病史和临床体征数据，并使用下肢静脉超声和静脉光电容积描记法（PPG）对静脉病理生理学进行客观评估。
临床检查发现，50名受试者中有80条下肢有CVD的临床证据，大多数病例为静脉曲张（CEAP C2）。没有下肢有愈合或活动性溃疡（C5/6），只有2条下肢有毛细血管扩张（C1）。8名受试者曾接受过静脉手术。PPG测量的静脉充盈时间（vRT）在患有CVD的下肢中较低。静脉超声检查显示，200条下肢中有73条存在反流，主要影响大隐静脉系统，只有7条下肢存在深静脉反流。
目前的数据有力地表明，英国亚裔进行浅静脉手术的比例较低并非因为他们天生患CVD的可能性较小。
