What are the 6 P’s of acute PAD clinical presentation ?
- Pain, Pallor, Poikilothermia, Pulselesness, Parasthesia and Paralysis.
What is the chronic presentation of PAD ?
- upto 50% are asymptomatic.
- It usually presents bilaterally with leg fatigue, intermitent claudication and ulcers.
What is the common vessel involvement in PAD ?
- Iliofemoral 44%
- Carotids 31%
- Aorta 31%
- CAD 18%
What are the risk factors for PAD ?
→ Older age
→ HTN
→ Tobacco use
→ Diabetes mellitus
→ Hypercholesterolaemia
What are the investigations in PAD ?
- Complete CV examination.
- Ankle-Brachial Index (ABI)
to assess severity of disease. - Duplex Ultrasound
- CT-angiogram
- MR-angiogram
- Angiography
What is the ABI in PAD ?
→ Normal >0.90
→ Mild 0.71-0.90
→ Moderate 0.41-0.70
→ Severe 0.0-0.40
How to perform Burger’s test in PAD ?
https://youtu.be/qJ4FR20zDzk
→ Raise 1 or both legs to 450
for 1-2 minutes
→ Observe the colour of the limbs and Note at what angle pallor occurs and the angle is Known as Buerger’s angle.
→ Sit the pt up and hang their legs over
the side of the bed
→ Look for reactive hyperaemia
What is the Burger’s test indication for severe ischemia ?
- colour change in <20 degree angle of leg elevation.
What is the non pharmacological management of PAD ?
- Lifestyle modifications
- Secondary prevention of CVD and smoking cessation.
What is the pharmacological management of PAD ?
PDE inhibitors such as
→ Cilostazol (Pletal)
→ Pentoxiphylline (Pentoxil)
What is the revascularization approaches in PAD ?
- Angioplasty
- Stenting
- Bypass grafting
- Amputation
What is the nidus of DVT ?
Virchow’s triad
What is the clinical presentation of DVT ?
→Pain
→Tenderness
→Swelling
What are the Px findings in DVT ?
→Swelling
→Palpable cord
→Discoloration
→Superficial vein dilation
What are the risk factors for DVT ?
- Major surgery
- Periods of
immobilisation - # s
- Cancer
- Hx of DVT
- OCP use
- Pregnancy or postpartum
What is the Well score classification of DVT risk ?
- ≤ 0 Low probability ( 5%)
- 1-2 moderate probability ( 17%)
- ≥ 3 high P ( 17-53%)
What is the Well’s criteria to manage low probability DVT cases?
First step is to check D-Dimer. If negative DVT excluded. If positive, perform duplex US and if positive begin anticoagulation or DVT excluded.
What is the Well’s criteria to manage Mod/High probability DVT cases?
First step is to Perform US (± D-Dimer). If positive begin anticogaulation, if uncertain repeat US and specialist consult. If negative DVT excluded.
What are the contraindications for anti-coagulants in DVT ?
Transient contraindication if retrievable IVC in situ and permanent contraindication, if permanent IVC in situ.
What are the indications for out patient management of DVT ?
If the patient does not have Phlegamisa or extensive illio-femoral DVT and no-contraindications for thrombolysis outpatient anti-thrombotic therapy with LMWH or tondaparinux can be done.
What are the indications for in patient management of DVT ?
If there are contraindications for thrombolysis in patient admission for catheter directed thrombolysis or IV systemic thromobolysis with UFH or LMWH or Tondaparinux can be done.
What is the duration of out-patient DVT managment ?
3 months
What are the drug choices in DVT?
→LMWH as bridge to PO agent
→Vit K antagonist (warfarin)
→Dabigatran
→Rivaroxaban or Apixaban
→UFH (only as inpt)
What are the preventive measures in DVT ?
- May require indefinite anticoagulation with Factor Xa inhibitors or Warfarin
- IVC filter for repeat DVT or high-risk PE.
- Ambulation
- Monitor for post-thrombotic syndrome.
- Prophylaxis for inpatients.
