Dr Frijo Jose A
Takayasu’s Arteritis
• 1830- Yamamoto • Kitsuo idan, meaning “Medical records of my private
hospital with the big orange tree”
• 1905- Takayasu, proff oph, presented the case of a 21 year old woman with characteristic fundal arteriovenous anastamoses
• Chronic inflammatory arteritis • Large vessels, esp, Aorta & its main branches
(brachiocephalic, carotid, SCL, vertebral, RA) • as well as Coronary & PA
• Chronic vasculitis • Affects Intima, Media, and Adventitia of larger
vessels • Wall thickening, Fibrosis, Stenosis, & Thrombus
formation →end organ ischaemia• More acute inflammation → destroys arterial
media → Aneurysm (fibrosis inadequate)• Stenotic lesions predominate & tend to be B/L• Nearly all pts with aneurysms also have stenoses
Two stage process
• 1. “Pre-pulseless” phase– Non-specific inflammatory features- fever, myalgias,
weight loss, & arthralgias• 2. Late occlusive phase– Vasc insufficiency, Diminished/absent pulses (84–
96%), Bruits (80–94%), Hypertension (33–83% ), RAS(28–75%) & CCF
• ± Intermittent flares
CHARACTERISTIC FEATURES
• ↓/− pulses (84–96%) -claudication & BP Diff• Bruits (80–94%) -carotids, subcl & abd vess• HTN (33–83%) -RAS (28–75%)• Retinopathy (37%)• AR (20–24%) -Dilated asc ao, valve thickening• CCF -HTN,AR,DCM• Neurological (HTN ±isch) -postural dizziness,
seizures, and amaurosis
d/d Coartation of aorta
• Symmetrical clinical involvement-co a(+rt ul)• Palpable collaterals-co a• Palpable abdominal ao pulsations- ta• Myocarditis- ta• Extensive bruits- ta• Fundus• Ar-both
Tuberculosis
• Erosion of vessel wall • True/False aneurysms• Esp- Desc thoracic & abdominal Ao• Dissection & Rupture rather than Stenoses
Syphilis
• Older age group• Calcification• Spares Desc thoracic Aorta• Stenoses are not a feature

A diagnosis of Takayasu arteritis requires that at least 3 of the 6 criteria are met

Ishikawa clinical classification of Takayasu arteritis
4 Complications Retinopathy, Secondary HTN, AR, & Aneurysm
Severity of Retinopathy (Uyama & Asayama‘s Classification)• stage 1- Dilatation of small vessels• stage 2- Microaneurysm formation • stage 3- Arterio-venous anastomoses• stage 4- Ocular complications
Mild -stage 1Moderate -stage 2Severe -stages 3 & 4
BP values were graded according to: Mild • brachial – SBP -140 to 159 mm Hg and/or 90 to 94 mm
Hg DBP, • popliteal – SBP- 160 to 179 mm Hg and/or 90 to 94
mm Hg DBP; Severe • brachial – SBP - ≥200 mm Hg and/or ≥110 mm Hg
DBP• popliteal – SBP- ≥230 mm Hg and/or ≥110 mm Hg DBPModerate • Between mild and severe forms.
Severity of aneurysm of Ao & branches (Angio)• Severe – D >twice that of normal vesselsSeverity of AR• estimated angiographically or clinically
Lupi-Herrera Classification
4 types: 1.Aortic arch variety • ≥1 of the 3 arch vessels 2.Thoracoabdomimal variety • Descending thoracic and/or abdo aorta and their
branches3.Combined variety• Both Arch vessels & thoracoabdo aorta4.Pulmonary variety • PA in combination with any of the preceding 3 types
4 types Type I (Shimizu- Sano variety) • Aortic arch & Brachiocephalic VesselsType II (Kimoto variety) • Thoracic descending & abdominal AortaType III• Both types togetherType IV (Lupi-Herrera variety)• Features of types I, II, & III in any combination
with PA involvement
Cumulative survival • 5years -91% (event free survival -74.9%)• 10 years -84% (event free survival -64%)Single mild complication or no complication • 5 year event free survival 97% Single severe or multiple complications• 5 year event free survival 59.7%No deaths in groups I and IIA19.6% mortality in groups IIB and III (CVA,CCF)

Treatment of TA
・
Steroids
immunosuppressants:Cyclosporin,Cyclophosphamide,Methotrexate,Mycophenolate mofetil
Anti-platelet therapy( low-dose Aspirin)
angioplasty/surgery
If uncontrolled
Control of vasculitis
Symptomatic occlusion
thrombosis
Medical treatment
• Steroids → 50% response• Methotrexate →further 50% respond• 25% with active disease will not respond to
current treatments
Indications and continual of steroids
Surgical treatment
• HTN with critical RAS• Extremity claudication limiting daily activities• Cerebrovascular ischaemia or critical stenoses of ≥3
cerebral vessels• Moderate AR• Cardiac ischaemia with confirmed coronary involvement
Recommended at quiescent state (restenosis, anastamotic failure, thrombosis,
haemorrhage, & infection)
Renal artery involvement
• Best treated by PTA• Stent placement following PTA– Ostial lesions– Long segment lesions– Incomplete relief of stenoses – Dissection
Sharma S et al, AIIMS Am J Roentgenol. 1992 Feb;158(2):417-22
• Renal PTA - 33 stenoses (20 pts) • Tech success -28 lesions (85%) • Failures - Coexistent abd Ao disease & tight, prox RAS• Tech diffi - tough, noncompliant stenoses, difficult to
cross & resisted repeated, prolonged balloon inflations - backache & ↓SBP during balloon inflation
• Follow-up 1-18 /12 (~8/12) -restenosis in 6(21%)• Renal PTA in TA -tech difficulties; Short-term results -
good, Complication rate-acceptable
aortoarteritic lesions
Balloon dilation diff from atherosclerotic lesions
• Minimal intimal involvement –permits easy wiring and balloon crossing
• Resistance to dilation – high fibrotic element in the stenotic lesion
Rao SA et al, SCT Radiology. 1993 Oct;189(1):173-9
• PTA -desc thoracic and/or abd Ao (TA) stenosis
• 16 pts (12+4)- HTN/severe B/L LL claudication• Aortography – stenosis→ desc
thoracic Ao-5, abd Ao-10, Both -1• Initial tech & clinical success -100% • Follow-up (mean 21/12,2/52)- Restenosis -3 • PTA has a definite role in TA management
Joseph S et al, SCTJ Vasc Interv Radiol 1994;5:573–580
• PTA- Scl A in TA• 24 pts (15 +9) →26 Scl A
VB insufficiency, UL claudication, or both
• Aortography → 19 steno ,7 occlu (focal-14 ,< 3 cm) • Initial tech & clinical success – 81%
(17 /19 steno,4/7occlu) • Follow-up → ~26/12 (max 82/12) → ISR -6 ( all ext)• Long-term results -excellent in focal lesions ,less
durable extensive disease
Tyagi S et al, GB Pant Cardiovasc Intervent Radiol. 1998 May-Jun;21(3):219-24
• To compare PTA- Scl A in TA & athero• 61 Scl A PTA (TA = 32 & athero = 29) • 3-120/12 (~43.3 +/- 28.9/12) follow-up of 40 pts• TA -Higher balloon inflation P• TA -more residual stenosis • TA –restenosis more• These lesions could be effectively redilated • TA -Subclavian PTA - Safe, can be performed as
effectively as in athero, good long-term results
Surgical techniques• Carry high morbidity & mortality• Steno /aneurysm -anastomotic points • Progressive nature of TA• Diffuse nature of TA
Balloon dilation • safe & reasonably effective• Can be performed repeatedly without any
added risks
However
• Post-PTA restenosis more frequently in TA than in atherosclerotic diseases, esp,in diffuse and long stenotic lesions
Takahashi et alAm J Neuroradiol 23:790–793, May 2002
• 1 TA pt –multiple supra-aortic lesions• B/L CCA, innominate, Lt Scl A• 2-staged stent implantation (to avoid drastic
changes in cerebral hemodynamics)• No restenosis -2 years despite rec inflamm
(2relapses) -may be effects of predonisolone
Stage-1
• 30-mm Palmaz stent mounted on a 40 mm PTA balloon-deployed at Lt Scl A stenosis
• Prox Rt CCA -dilated with 40 mm PTA balloon • Because long-term outcome of carotid PTA, with
or without stent , was not known for inflammatory arteritis-did not use stent support for CCA lesion during 1st treatment
• Ticlopidine (100 mg/day), cilostazol (100 mg/ day), prednisolone (5 mg/day)
Stage-2
• After 1/12 • 50 mm self-expanding Easy Wallstent -placed
from Rt CCA to innominate A• 50 mm Easy Wallstent -deployed in Lt CCA• Dilated -40 mm PTA balloon
Coronary involvement in TA
• Occurs in 10~ 30%• Often fatal• Classified into 3 pathorogic types
Type1:stenosis or occlusion of coronary ostiaType2:diffuse or focal coronary arteritisType3:coronary aneurism
Treatment for cor A occulusion in TA
Surgery (CABG,MIDCAB)- often not indicated・ IMA can’t be used often– occlu of Innomi A / Scl A– calcification of aorta
High incidence of restenosis:36%Angioplasty(PTCA)・ alternative to surgery Very high incidence of restenosis:78%DES?
Arterial access in ta-all 4 limbs involved
• Venous- trans-septal• Trans-seeptal problem– No aortic land mark– May be tackled by– His bundle catheter– Atrio-ventricular groove fat visualisation on flouro
PREGNANCY
• Pregnancy per se does not appear to exacerbate TA- management of HTN essential
• Meas of BP in UL –impossible/unreliable → oft more accurate in legs
• HTN in 2nd stage Labour –risk for ICH; shortening stage by low forceps /vacuum –reasonable
• pre-eclampsia, CCF, progressive RF,CVA
Take home messages
• Angiography remains gold standard for diagnosis• 4 most imp complications - Retinopathy,
secondary HTN, AR & aneurysm• ~½ on steroids will respond, and ~½ remaining
respond to methotrexate, mycophenolate mofetil• Pregnancy does not appear to exacerbate the
disease, although management of hypertension is essential
