Peritonitis causing acute limb ischaemia.

A patient presented with an acutely ischaemic leg and mild abdominal pain. Arteriography showed an iliac occlusion and some distal occlusive disease. At laparotomy a perforated gastric ulcer was found, and by the end of this operation the foot was well perfused. This case exemplifies the serious reduction in limb blood supply which can be caused by an acute illness, without thrombosis of vessels. It emphasises the importance of general assessment and treatment of any associated acute condition, in cases of acute limb ischaemia.

Sliding hip screws: modes of failure.

The modes of failure of the sliding hip screw devices were investigated by reviewing 223 cases. There were 35 mechanical failures. Two of these occurred when the components separated in highly comminuted fractures. The use of the locking screw is recommended to prevent this. The other 33 occurred when the device had lost its sliding action. The reasons for this included jamming, insufficient slide being available and additional fixation. To reduce the complication rate it is recommended that any additional fixation (such as cerclage wires) should be used with care to ensure that they do not block the barrel. For patients with short femoral necks, a shorter barrelled version of the device should be used as it would have a greater sliding capacity. Guidelines for its use are given.

Arterial embolectomy. A long-term perspective.

One hundred and thirteen elderly patients (median age 77 years, range 37-99) were followed up for 2-10.5 years after embolectomy in order to assess the late outcome. There were two groups of patients: those who had suffered an embolism (84) and those who in retrospect had thrombosis in situ (29). Thirty three of the embolus group (39%) died within 30 days of surgery, and factors associated with mortality (p less than 0.05) were age greater than 80 years, and failure to save the limb (17%). In the thrombosis group limb loss was more common (76%) and these patients also had a higher mortality (55%). Mean long term survival in the embolus group was 35 months (range 1-108 months) with a high mortality rate in the first 6 months after embolectomy and improved survival after this. There were no significant differences in mortality or cardiovascular events between the 27 patients on long term warfarin and the 19 patients not anticoagulated. Mortality after embolectomy is high but there remains a group of long term survivors. The value of oral anticoagulation for these patients remains unresolved.
