Venous Dx Flashcards
(21 cards)
Q/ What’s varicose vein’s, & it’s common in male or female?
it is dilated, usually tortuous, subcutaneous veins 3 mm in diameter measured in the upright position with demonstrable reflux.
More common in females
Give 3 risk factors for venous dysfunction?
● Heredity
● Female sex,
● Hormonal Influence
What are the indications to treat Varicose Veins?
1•Symptomatic (aching, heaviness, and cramps)
2•Complicated pigmentation, dermatitis, induration, superficial ulceration, and thrombosis of varicosities
3•Large varicosities subject to trauma
4•Cosmetic concern
What are the treatment options for varicose veins ?
1- non surgical Tx : compression stockings, elevation of lower limbs, exercise of leg muscles
2- Minimal invasive techniques: thermal oblation, non thermal cyanoacrylate ,sclerotherapy,
3- Surgery: proximal ligation, stab avulsion
What’s the etiology behind VTE ?
1- stasis of blood flow.
2- endothelial damage.
3- the hypercoagulable state.
What is DIAGNOSTIC EVALUATION OF VENOUS DYSFUNCTION?
•Perthes test
•Brodie-Trendelenburg test
•Plethysmography
•Duplex Doppler Ultrasonography
What is VENOUS THROMBOSIS?
is the formation of a semi-solid
coagulum within the venous system and may occur in the superficial system (usually described as
superficial thrombophlebitis) or the deep system (deep venous thrombosis or DVT).
1ry or spontaneous DVT caused by ?
Hypercoagulanle state
2ry DVT caused by?
occur after immobilization, surgical procedures, and trauma.
How Hypercoagulable State happened?
■ Factor V Leiden mutation
■ Prothrombin gene mutation
■ Protein C deficiency
■ Protein S deficiency
■ Antithrombin III deficiency
■ Antiphospholipid syndrome
Sequence of Pathology
Propagation to involve more proximal segments of the deep
venous system
• Pulmonary embolism
• The late consequence of DVT, particularly of the iliofemoral
veins, can be CVI and ultimately post-thrombotic syndrome,
as a result of valvular dysfunction in the presence of luminal
obstruction.
• Recanalization
Give 3 risk factors for DVT ?
• Past history DVT.PE
• Increase age
• Immobility
• Malignancy
• Surgery or trauma
• Cardiac failure , stroke and MI
• Oral contraceptive
• Thrombophilia
What are the complications of DVT ?
PE, CVI, paradoxical emboli, phlegmasia caerulea doles
Approach to patient with suspected DVT ?
1• History pain,swelling,distended vein,skin discolation,ulceration,risk factors
2• Clinical: high index of suspicion, +ve Homans’ sign , Calf tenderness is frequently present, swelling of the foot and calf, phlegmasia alba dolens, phlegmasia cerulea dolens, venous gangrene
3• Investigations: Venography, Impedance Plethysmography, Fibrin, Fibrinogen Assays And Magnetic Resonance Venography
What are the prophylactic measures for DVT ?
1- mechanical: leg elevation, early mobility, intermittent pneumatic compression and graduated compression stockings.
2- Pharmacological: low dose UFH, LMWH, synthetic pentasaccharides, dextran 70 and vitamin K antagonists (warfarin)
Give the treatment options for DVT ?
1- pharmacological (Antithrombotic therapy like UFH, LMWH, Warfarin, apixaban & rivaroxaban
2- non pharmacological :
* Temporary or permeant IVC Filter
* Systemic or direct catheter thrombolytic therapy
* Operative thromboectomy
What is the Surgical Treatment of Chronic Venous Insufficiency?
- Perforator Vein Ligation
- Venous Reconstruction
- Valvoplasty, or valve repair
Chronic Venous Insufficiency
• leg fatigue, discomfort, and heaviness.
• leg fatigue, discomfort, and heaviness.
• varicose veins, edema.
• hyperpigmentation, lipodermatosclerosis.
• venous ulceration.
• Chronic venous insufficiency or the postthrombotic
syndrome develops in approximately 50 percent of the
patients with deep venous thrombosis.
Treatment of Chronic Venous
Insufficiency
Non operative Treatment of Chronic Venous
Insufficiency
Compression Therapy:
•Graduated elastic compression stockings
•Unna’s boot
•Multilayered dressings
Surgical Treatment of Chronic Venous Insufficiency
•Perforator Vein Ligation
•Venous Reconstruction
What is the differences between venous, arterial & diabetic ulcers, regarding their cause, location amd associated signs & symptoms?
1- Venous ulcer:
Cause: venous hypertension 2ry to DVT or varicose veins
Location: medial side of leg, above ankle
Associated signs & symptoms: it’s shallow with sloping edges, bleeds easily after minor trauma & surrounded by pigmentation associated dermatoliposclerosis.
2- Arterial ulcer
Cause: Occlusive arterial disease
Location: lateral ankle, heel, metatarsal heads, tips of the toes
Associated signs & symptoms: painful ulcers, do not bleed, nonhealing, with associated features of ischemia, e.g. claudication, absent pulses, pallor.
3- Diabetic ulcer
Cause: ischemia or neuropathic
Location: plantar aspect of foot or toes
Associated signs & symptoms: it’s deep, painless ulcers associated with cellulitis, deep tissue abscesses, warm foot, pulses may be present.
LMWH advantage over UH:
1- more potent
2- longer duration if action
3- less frequent dosing
4- lower risk of heparin-induced thrombocytopenia
