A prospective randomised trial of 50 patients was carried out to assess the
autoclavable Lofquist cuff (Boazal, Sweden) as a tourniquet in varicose ve
in surgery and determine the effect on bleeding, bruising, cosmesis and pat
ient pain and activity.
Patients undergoing unilateral long saphenous vein Ligation, stripping and
avulsions were randomised to tourniquet or no tourniquet. Lofquist cuffs we
re applied after inflation to 120 mmHg to the upper thigh for the duration
of the surgery, Varicose vein grade, duration of surgery, blood loss, exten
t of bruising at 7 days, pain and activity scores over the first week, and
wound complications and cosmetic result at 6 weeks were recorded. Patients'
age, sex, and varicose vein grade were similar in the two groups. Peropera
tive blood loss (median, range) was significantly reduced in the tourniquet
group (0 ml, 0-20 ml) compared to the no tourniquet group (125 ml, 20-300;
P < 0.01). Operative time and thigh bruising (median, range) were also red
uced in the tourniquet group (30 min, 11-47 min; 72 cm(2), 30-429 cm(2)), r
espectively, compared to the no tourniquet group (37 min, 18-50 min; 179 cm
(2), 24-669 cm(2)) both (P < 0.01). There was no difference in pain and act
ivity scores in the two groups and cosmetic results were also similar
The use of the Lofquist cuff tourniquet during varicose vein surgery reduce
s peroperative blood loss, operative time and postoperative bruising withou
t any obvious drawbacks.
