Thrombo-embolectomy and thrombolytic therapy in acute lower limb ischaemia. A five year experience
Between 1988 and 1993, 82 patients with a median age (iq range) of 81 (73-87) years underwent thrombo-embolectomy (TE) and thrombolysis for acute lower limb ischaemia at the Royal Hallamshire Hospital, Sheffield. 28 patients (Group 1) underwent TE prior to the introduction of thrombolysis in 1991. TE with intraoperative thrombolysis (IT) as an adjunct was performed in 34 patients (Group 2) and 20 patients (Group 3) were treated using percutaneous thrombolysis (PT) in the first instance. 41 of these patients were in AF at presentation. Although 24 were on digoxin, only 4 were on warfarin. Group 3 patients were younger (p < 0.05; ANOVA) with a longer duration of ischaemia (p < 0.05; ANOVA) and had less limbs suffering a sensorimotor deficit (p = 0.007; chi 2) compared with Groups 1 and 2 which were similar in these respects. Overall mortality was 17%. Successful revascularisation was achieved in 18 (64%), 28 (82%) and 15 (75%) patients in Groups 1, 2 and 3 respectively. 14 of the 15 patients successfully treated initially by PT required further intervention in order to maintain revascularisation. Revascularisation failure was associated with the presence of a sensorimotor deficit but not associated with patient age or duration of ischaemia.
