II. Epidemiology
- Upper extremity accounts for 5-10% of Deep Vein Thrombosis (DVT)
- Patients tend to be younger and of leaner body habitus than those with lower extremity DVT
III. Anatomy
- Deep Veins of Arm- Proximal Deep Veins- Subclavian Vein (most common DVT site)
- Axillary Vein (common DVT site)
- Internal Jugular Vein (included in Upper Extremity DVT by some authors)
- Brachiocephalic Vein
 
- Distal Deep Veins- Brachial Vein
- Radial Vein
- Ulnar Vein
 
 
- Proximal Deep Veins
- Superficial Veins of Arm- Cephalic Vein
- Basilic Vein
 
IV. Causes
- Central Venous Catheter (common)
- PICC Line Thrombosis (complicates 3-5% of PICC Lines)
- Effort Thrombosis (Paget-Schroetter Syndrome)- Incidence 1 to 2 per 100,000 per year in U.S.
- Venous form of Thoracic Outlet Syndrome- Musculoskeletal swelling of axilla and upper arm results in external
- Compression interferes with arm venous outflow
 
- Occurs in athletes with upper extremity Muscle hypertrophy (rowers, swimmers, pitchers, tennis players, weight lifters)- Overuse with hypertrophy of scalene Muscles, especially in dominant arm
- Increased risk with congenital cervical ribs or subclavius ligaments
 
 
- Idiopathic (uncommon)- Evaluate for occult cancer (up to 40% of Upper Extremity DVT causes)- More likely than with lower extremity DVT
 
- Consider evaluation for Hypercoagulable state
 
- Evaluate for occult cancer (up to 40% of Upper Extremity DVT causes)
VI. Signs
- Arm with palpable cord
- Supraclavicular fullness
- Cyanosis or bluish discoloration of the extremity
- Serous drainage from PICC Line insertion site
- Venous distention- Superficial vein distention (esp. chest wall and Shoulder)
- Jugular Venous Distention
 
VII. Differential Diagnosis
VIII. Imaging
- Images
- Duplex Ultrasound of upper extremity- Test Sensitivity and Test Specificity approach 100% with skilled ultrasonagrapher
- Proximal subclavian vein may be difficult to image (clavicle shadowing)
 
- Advanced imaging options in indeterminate Ultrasound- CT or MRI (timed for venous phase evaluation)
 
IX. Management: Proximal Upper Extremity Deep Vein Thrombosis
- Indications: Proximal Deep Vein Thrombosis- Subclavian Vein Thrombosis
- Axillary Vein Thrombosis
- Internal Jugular Vein Thrombosis
- Brachiocephalic Vein Thrombosis
 
- 
                          Anticoagulation
                          - See Anticoagulation in Thromboembolism
- Duration: Typically 3 months (6 months or longer may be required if persistent risk)
 
- Consider catheter directed Thrombolysis (severe acute edema, pain presentations)- Large thrombus
- Acute within last 2 weeks
- Patients with low bleeding risk
 
X. Management: Distal Upper Extremity Deep Vein Thrombosis
- Indications: Distal Deep Vein Thrombosis- Brachial Vein
- Radial Vein
- Ulnar Vein
 
- Approach- Observation (typical) OR
- Prophylactic dose Anticoagulation OR
- Therapeutic dose Anticoagulation (high risk patients)- Catheter-Associated Venous Thrombosis and catheter remaining in place (see below)
- Cancer patients with low risk of bleeding
 
 
XI. Management: PICC Line Venous Thrombosis
- 
                          PICC Line venous thrombosis risk: 2.5%- May present as serous drainage from the PICC insertion site
 
- New Recommendations- PICC Line does not need to be removed in most Upper Extremity DVTs (if functional and ongoing need)
- Anticoagulate for 3 months regardless of presence of cancer (or as long as PICC in place if longer than 3 months)
- Older recommendations were to remove the PICC Line and not replacing (even if placed on opposite side)

XII. Complications
- Pulmonary Embolism (6% of cases; contrast with lower extremity DVT related PE of 33%)
- Post-thrombotic Symdrome (13% of cases)
- Superior Vena Cava Syndrome
