UEDVT — primary (Paget-Schroetter) vs secondary (catheter-associated) classification is the central differentiator; routes diverge significantly
subtype classified
Patient inputs (7)
Primary UEDVT typically young; secondary UEDVT typically older with comorbidities
Primary vs secondary subtype drives management (CDT consideration vs catheter removal decision)
Compression US is first-line; CT venography or MRV if non-diagnostic (Joffe ASH 2017)
Baseline + platelet count for AC + HIT screening if heparin-exposed catheter
HAS-BLED for AC eligibility
eGFR for DOAC dosing
If indwelling catheter present: is it essential? If not, remove (Joffe ASH 2017); if essential, continue AC while in place

Auto-drafted A&P note
outpatientSubjective
- Possible entry pathways: Unilateral arm swelling, pain, warmth, prominent collateral veins → suggests UEDVT; Young athlete with repetitive arm overhead activity (rowing, swimming, weightlifting) → Paget-Schroetter (primary UEDVT); CVC, PICC, port, or pacemaker lead present → secondary UEDVT (most common cause).
Objective
- No vitals, labs, or imaging entered for this encounter.
Assessment
**Upper-extremity DVT (subclavian / axillary / brachial)** (cardio.dvt.upper-extremity.v1). Scope: UEDVT — primary (Paget-Schroetter) vs secondary (catheter-associated) classification is the central differentiator; routes diverge significantly No severity triggers fired against current inputs.

Regimen axis: **Upper-extremity DVT anticoagulation — DOAC-first per ACCP 2021**. 1. apixaban 10 mg BID × 7 d → 5 mg BID PO BID × ≥3 months (or while catheter in place) (doac_factor_xa_direct, first line) — AMPLIFY PMID 23808982 — UEDVT extrapolated; ACCP 2021 supports DOAC for UEDVT 2. rivaroxaban 15 mg BID × 21 d → 20 mg daily PO BID then daily × ≥3 months (doac_factor_xa_direct, first line) — EINSTEIN-DVT subgroup; ACCP 2021 3. edoxaban 60 mg daily after 5 d LMWH lead-in PO daily × ≥3 months (doac_factor_xa_direct, first line) — Hokusai-VTE PMID 23991958 — UEDVT included in trial 4. enoxaparin 1 mg/kg SC BID SC BID (lmwh, comorbidity specific) — ASH 2018 in pregnancy; CARAVAGGIO PMID 32223112 alt in cancer-UEDVT 5. alteplase 0.5-1 mg/h via catheter for 12-24 h IV_catheter continuous infusion (fibrinolytic_tpa, comorbidity specific) — CDT for primary (Paget-Schroetter) within 14 d restores venous patency; Engelberger Thromb Res 2014; Joffe ASH 2017 Setting playbook (outpatient) — Long-term surveillance: primary post-first-rib resection (most patients durable patency); secondary post-AC course; rare extended-AC scenarios 6. no AC post-treatment for resolved UEDVT n/a n/a n/a — Completed 3 months AC + risk factor resolved (ACCP 2021) 7. extended-phase apixaban if unprovoked or recurrent apixaban 2.5 mg BID PO BID — Unprovoked recurrent UEDVT or persistent risk (AMPLIFY-EXT PMID 23216615) Non-pharmacologic actions: - Activity modification if athlete (primary UEDVT) post-surgery - Catheter alternatives counseling if recurrent secondary UEDVT AVOID / contraindication checks: - Doac_avoid_active_bleeding (FDA labels) - Apixaban_avoid_egfr_below_15 (FDA label) - Cdt_avoid_if_bleed_risk_high (CDT major bleed ~5% — Joffe 2017) - Decision:remove_non_essential_catheter (Joffe ASH 2017 — most catheter UEDVTs resolve with removal + AC) - Decision:retain_essential_catheter_with_AC (Kahale et al. Cochrane 2018)
Monitoring
Regimen monitoring: - cbc q week x first 4 weeks (ASH 2020) - arm circumference at baseline and 3mo for residual swelling - venous patency us at 3mo post cdt for paget schroetter - reassess catheter need weekly if secondary Setting (outpatient) monitoring: - Annual reassessment Follow-up plan: Primary: surgical (thoracic surgery / vascular) consult for first-rib resection within 4-6 weeks. Secondary: AC continued while catheter in place (or 3 months if removed) - Close-out criterion: long-term plan documented Monitoring phase: Bleeding screen; arm function (residual swelling, dexterity); for primary post-CDT: venous patency surveillance; for secondary: re-evaluate catheter need
Disposition
Current setting: outpatient — Long-term surveillance: primary post-first-rib resection (most patients durable patency); secondary post-AC course; rare extended-AC scenarios Disposition criteria: - Long-term annual follow-up Escalation triggers (move to higher acuity): - Recurrent UEDVT → re-evaluate anatomy and AC strategy
Earlier-Return Triggers
Return-precaution thresholds (watch for): - [LIFE_THREATENING] UEDVT extending to or causing SVC syndrome (facial swelling, plethora, dyspnea, dilated chest collaterals) - [LIFE_THREATENING] UEDVT with concurrent PE (~10-15% rate) — particularly common in catheter-associated UEDVT - [SEVERE] Massive UEDVT with brachial plexus compression causing new motor or sensory deficit
