Drug misuse is now a significant problem in western society; many different pharmaceuticals are administered by drug abusers as intravenous preparations. This has resulted in an increasing number of complications associated with prolonged intravascular and perivascular injection of abused substances. These complications of intravenous drug abuse may lead to limb-threatening arterial injuries that present a considerable management problem in patients who often have significant comorbidity. This article provides a comprehensive review of the vascular complications that result from drug misuse by injection. It discusses the aetiology and clinical features of these complications and highlights the limited role of both the general surgeon and specialist vascular surgeon in the management of these patients.
Only 30 per cent of unselected AAAs presenting to a vascular service are entirely suitable for EVAR; most of these patients can safely undergo open AAA repair. These data suggest that increased use of EVAR is only possible by deploying devices in suboptimal morphology, and in treating patients who would not normally be considered for open AAA repair.
These data indicate that CT has little additional diagnostic value. If in the opinion of an experienced vascular surgeon rupture cannot be excluded on clinical grounds alone, and the patient has no medical contraindications to abdominal aortic aneurysm repair, then the patient should be taken directly to the operating department.
Background: A multicentre randomised controlled trial to determine the effect of a rigid plaster dressing applied at the time of trans-tibial amputation on the number of days to casting for a prosthesis, and the incidence of post-operative stump infection. Methods: Patients requiring trans-tibial amputation were randomised to one of 2 groups: In Group 1 (intervention) a rigid above-knee plaster dressing was applied at operation and patients were managed according to a standard protocol. Group 2 (control) had the individual surgeons' usual non-rigid dressing regime. Rehabilitation data were extracted from the national physiotherapy database. On completion of the trial a questionnaire was sent to all participants. Results: 14 surgeons in 7 centres enrolled 154 patients, with 96 ultimately cast for a prosthesis. Patients who received a rigid dressing (n=78) had reduced days to casting (median 36, confidence interval 30–47) when compared with other dressings (n=76) (median 42, confidence interval 36–45), these differences did not reach statistical significance. There was no significant difference in post-operative infection rates in the two groups. 64% of surgeons, and all physiotherapists and vascular nurses responding to the post-trial questionnaire felt that the rigid dressing was an improvement on their normal regime and wished to continue with the technique. Conclusions: Despite a median reduction of 6 days in time to casting in patients treated with a rigid post-operative dressing this failed to reach statistical significance: The majority of participants who replied to the post-trial questionnaire expressed a wish to continue using the rigid dressing technique. To confirm that the trends shown in this trial are statistically valid a larger trial is needed.
Successful endoluminal aneurysm exclusion is associated with reduced aneurysm diameter. However, longer term results of endoluminal repair, in particular of sealed endoleaks, are required before randomized controlled trials of endoluminal versus conventional repair can be undertaken.
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.
