5-5.9cm 25%
6-6.9cm 35%

50% prehospital mortality
50% perioperative mortality
25% of rAAA will survive
How do we improve this?
18. UK small Aneurysms trial UK small aneurysm trial
1090 Asx patients randomised to either early surgery or observation
Rupture rate of <2%/yr less than 5cm diameter
No evidence for survival benefit with diameter <5.5cm
19. Screening Several trials
Gloucester
Cambridge
Chichester
55% reduction in ruptures in screened population vs controls
Favourable results with single US at 65
National programme Prevent upto 80% of ruptures
Implementation in progress

33. EVAR 1
1100 patients
Open vs EVAR in patients fit for surgery
No change in all cause mortality despite promising 30d decrease mort in EVAR
Cost roughly equal for procedure but much higher ongoing cost in EVAR
34. EVAR I Trial
36. EVAR 2 Small 388pts

No diff in all cause or AAA related mortality
Overall mortality at 4yrs=64%

41. Bottom line Seen by Vascular Surgeon
Appropriate Imaging

42. Late complications requiring surgical management Graft limb occlusion
Persistent endoleaks with continued aneurysm expansion
Graft failure
Endotension
AAA rupture
Miscellaneous (graft infection, aortoduodenal fistula)
44. The Future?
45. Day 1 post op
46. The Future Screening
More EVAR
Currently 30-40% in York
More complex EVAR
Branched
Fenestrated
Less Open Surgery
But More Complicated
47. Acute Limb Ischaemia Aetiology:
emboli
thrombosis
trauma
iatrogenic
drug abuse
venous outflow blockade
low flow states
49. Acute Limb IschaemiaEmbolus vs Thrombosis
50. Acute Limb Ischaemia Incidence of embolic occlusion :
femoral 36%
aortoiliac 22%
popliteal 15%
upper extremity 14%
visceral 7%
other 6%
51. Acute Limb Ischaemia Signs of acute ischaemia :
pale extremity
temperature change - sharp demarcation
pain
paraesthesia
paresis
mottled or cyanotic limb
53. Acute Limb Ischaemiaclinical categories
54. Clinical scenarios of acute limb ischaemia Sudden onset in previously asymptomatic individual
History: age, PMH, co morbidity
Remember POPLITEAL ANEURYSM
Sudden deterioration in a patient with PVD
Recurrence of symptoms in a patient with a previous bypass graft
All Require urgent referral
56. Management of acute limb ischaemia Diagnosis of underlying pathology
Prevention of deterioration whilst awaiting Rx
Avoidance of complications
Preparation for theatre
Management of thrombus
57. Acute Limb Ischaemia Definitive measures
embolectomy
thrombectomy
bypass procedure
Thrombolysis
+/- fasciotomy
58. Thrombolysis Catheter directed
Potentially a high-risk strategy
Complications include CVA, GI bleeds, bleeding from puncture sites and compartment syndrome
Usually reserved for limb-threatening ischaemia; but remember contraindications
Monitor for development of complications
61. Claudicants Risk Factor Management
Smoking cessation
Anti platelet
Statin
Routine referral for consideration of intervention
No defined distance for treatment
62. Critical Ischaemia PVD +
Tissue loss
Rest pain
Urgent outpatient referral
Next available clinic
Fax referral to Harrogate/York Secretaries
If concern regarding infection or viability refer to on call vascular team
63. Carotid Disease
64. Surgery For Symptomatic Stenoses ECST/NASCET: similar results
Stenosis*
<70% conservative management
>70% CEA & medical treatment
6-10x decreased risk of stroke compared to best medical treatment alone
*Using ECST measurement criteria 2 large studies in symptomatic patients, European and North American. Used different measurement criteria. Best medical therapy was antiplatelet plus risk factor management.2 large studies in symptomatic patients, European and North American. Used different measurement criteria. Best medical therapy was antiplatelet plus risk factor management.
65. ACST Conclusions Patients under 75 with ASx Stenosis >70% and best medical therapy who are offered immediate CEA half their 5 year stroke risk (from 12% to 6%)
Outside trials patient selection, poor surgery or delay could obviate benefits No reason to scan over 75s who are asymp.No reason to scan over 75s who are asymp.
