Now let me analyze the prescription carefully and provide a comprehensive breakdown.
Patient Summary
Patient: Hasina, 29F | Institution: NIMS, Hyderabad | Department: Vascular Surgery | Date: 02-Jun-2025
Diagnosis
K/o (Known case of) Vasculitis with:
- Bilateral total vessel disease
- Stopped medicines & lost to follow-up
- Presenting complaint: C/o leg pain
Doppler Study Findings
| Parameter | Left | Right |
|---|---|---|
| Normal CAS | — | — |
| DP (Dorsalis Pedis) | Absent | Absent |
| PT (Posterior Tibial) | Normal | Normal |
| Pop (Popliteal) | Normal | Normal |
| Fem (Femoral) | Normal | Normal |
Absent DP pulses bilaterally with preserved proximal flow suggests distal small vessel vasculitis — consistent with Buerger's disease (Thromboangiitis Obliterans) pattern in a young patient, or systemic small vessel vasculitis.
Prescribed Medications (Decoded)
First Visit Medications (1 month):
| # | Drug | Dose | Frequency | Purpose |
|---|---|---|---|---|
| 1 | T. Rosuvas / Rosuvastatin | 2.5 mg | 9am + 7pm | Vascular inflammation, dyslipidemia |
| 2 | T. Roverstat-A (Rosuvastatin + Aspirin) | 75/20 mg | 2pm | Antiplatelet + statin |
| 3 | T. Pletodol / Cilostazol | 50 mg | 9am + 7pm | Vasodilator, antiplatelet for claudication |
| 4 | Cap. Dobesilate (Calcium Dobesilate) | 500 mg | Once daily | Capillary stabilizer, microangiopathy |
| 5 | Cap. CoEnzyme Q10 | 10 mg | Once daily | Antioxidant, vascular support |
| 6 | T. Reno-MNP (Modified-release Isosorbide Mononitrate) | — | 7pm | Vasodilator |
| 7 | T. Homostron Forte | — | 6pm | Likely analgesic/supportive |
Management Principles for Bilateral Vasculitis (Lower Limb)
1. Lifestyle & Causative Factors
- Complete smoking cessation is the single most critical intervention (Bailey & Love, p. 1045)
- Avoid cold exposure, trauma to extremities
- Wound care for any ulcers
2. Pharmacological Management
Antiplatelet therapy:
- Aspirin 75 mg (antiplatelet) — as in Roverstat-A
- Cilostazol 50–100 mg BD — vasodilation + antiplatelet; improves walking distance and reduces claudication
Vasodilators:
- Isosorbide Mononitrate (Reno-MNP) — improves peripheral perfusion
- Nifedipine in Raynaud's component
Statin therapy:
- Rosuvastatin — anti-inflammatory + pleiotropic vascular benefit
Microcirculation support:
- Calcium Dobesilate — reduces capillary permeability, anti-inflammatory at microvessel level
Immunosuppression (for systemic vasculitis, if ANCA-associated or autoimmune):
- Glucocorticoids + Rituximab — now standard initial therapy, particularly for ANCA-associated vasculitis (Harrison's, p. 12739)
- Cyclophosphamide + glucocorticoids — alternative
- Mepolizumab — for eosinophilic granulomatosis with polyangiitis
3. Investigations Recommended
- Duplex Doppler (done — bilateral)
- ANA, ANCA (p-ANCA/c-ANCA), anti-dsDNA
- ESR, CRP, CBC
- Ankle-Brachial Index (ABI)
- Angiography if surgical intervention considered
4. Surgical Options (if conservative fails)
- Sympathectomy (lumbar) — improves distal flow
- Revascularization — limited in distal disease
- Amputation — last resort if gangrene develops (Bailey & Love, p. 1045)
Key Points for This Case
- Patient is 29F — young; Buerger's is more common in young male smokers, but vasculitis (autoimmune) should be strongly considered in a young woman
- Absent DP bilaterally with preserved proximal flow = distal vessel involvement
- Patient was lost to follow-up and stopped medications — medication adherence counseling is critical
- 1-month follow-up prescribed — reassess symptoms, repeat Doppler if needed
- Autoimmune workup (ANCA, ANA) should be done if not already completed given the demographic
