Q

What is venous reflux?

A

Where the pressure of gravity on the veins causes the veins to dilate over time until the valve is incompetant and blood flows backwards down the vein

Q

What is superficail Thombophlebitis?

A

Causes redness, pain and tenderness.

Q

How are varicose veins investigated?

A

An ECHO
Looks at valves at sapheno-popliteal & sapheno-femoral junctions for incompetence & backflow

Q

When do we intervene in varicose veins?

A

If theres:
- Superficial Thrombophlebitis
- Haemorrhage
- Anxiety about progression
- Serious cosmetic issues
- Signs its progresse to CVI

Q

What surgical treatments are there for varicose veins?

A

Ligation of of the junction where the incompetent valve is. (tying it up)
Vein Stripping with multiple stab avulsions (small holes through which its removed, also called phlebectomy)

Q

What are the low invasion treatments for Varicose Veins?

A

Foam Sclerotherapy - A chemical reaction with endothelium closes the vein with foam

Endovenous Laser Ablation (EVLA) or Radiofrequency Ablation both close the vein.

Q

How does CLI arise from Varicose veins?

A

Varicose veins cause the deep veins to act as collateral circulation.
Eventually they too can undergo venous reflux and become tortuous & dilated, the now hypertensive veins ooze exudate which inflames surrounding tissue causing CVI

17
Q

What is ambulatory venous pressure?

A

The venous pressure when upright and moving.
A high one = venous hypertension

18
Q

What possible causes are there for CLI?

A

Superficial & deep Venous reflux (superficial can mean varicose veins)
Venous obstruction
Obesity
Neuromuscular causes
Inactivity

19
Q

What aer the risk factors for CLI?

A

Female
Prolonged Standing (often occupational)
Crossing Knees
Obesity
