1

Raynaud's disease pathophysiology

Digital ischaemia caused by paroxysmal vasospasm

2

Raynaud's phenomenon

pale (ischaemia)  -> blue (deoxy) -> red (reactive hyperaemia) 

3

Raynaud's rx in mild disease

Keep warm

Stop smoking

Meds: Nifedipine, sildenafil

Primrose oil

 

4

Raynauds rx in severe (gangrenous) disease

Prostacyclin

Digital or lumbar sympathectomy 

5

Carotid endarterectomy indication

Symptomatic + ipsilateral obstruction ≥70%

 

(no point in doing it for a fully blocked vessel)

6

How soon after presentation should the carotid endarterectomy be carried out

within 2 wks

7

Main complications of endarterectomy

Stroke/death 

hypoglossal n injury

8

Post-phlebitic syndrome aka

post-thrombotic syndrome

9

Cause of post phlebitic syndrome

long term complication of DVT

10

Post phlebitic pathogenesis

Clot/damage to valve -> venous HTN

Rupture of superficial valves

-> bleed/swelling/pain

11

Trendelenberg's test procedure

1. Supine patient, raise leg, tourniquet the thigh (to occlude superficial vessels). 

2. Stand up the patient, time how long it takes for blood to return 

3. If no refill after 20 s at all, release turniquet and time how long it takes for blood to return

12

Trendelenberg's interpretation 

Step 2 normally takes around 30-35 s

If no refill, but step 3 happens rapidly, shows the deep veins are competent and it's a superficial vein problem
