Frame
DVT with coexistent PE = combined VTE; manage as PE-driven (typically more dangerous given hemodynamic + gas-exchange dimensions); inherit DVT diagnostic + AC arc; route to pulm.pe.core.v1 for PE-specific hemodynamic management when RV strain present
both DVT and PE confirmed on imaging
Patient inputs (11)
Age modifies PESI/sPESI score for early mortality risk; informs outpatient candidacy (HESTIA)
Confirms DVT and laterality / proximal extent for IVC-filter and CDT consideration
CT-PA is gold-standard for PE confirmation, clot location (saddle vs lobar vs segmental), and RV/LV ratio measurement (RV/LV >0.9 = RV strain per ESC 2019)
Baseline Hgb + platelets before AC + thrombolytic-bleed risk stratification
SBP <90 for ≥15 min OR vasopressors needed = massive (high-risk) PE per ESC 2019 — fundamentally changes management to systemic thrombolysis
Hypoxemia magnitude correlates with PE clot burden + RV strain; informs O2 + escalation
Bleed history drives AC + thrombolytic eligibility; absolute contraindications shift to IVC-filter consideration
Bedside echo for RV dilation, septal flattening, TAPSE, McConnell — drives sub-massive vs low-risk classification when CT-PA shows PE without hypotension
Elevated troponin in PE = RV myocardial injury; combined with RV strain → sub-massive (intermediate-high risk per ESC 2019)
Provoked vs unprovoked drives AC duration decision at 3 mo (same as isolated DVT/PE)
eGFR for DOAC + LMWH dosing + contrast load for CT-PA
* = hard-required. Engine cannot meaningfully run until these are filled.

Disposition
Current setting: outpatient — Long-term AC management, PTS surveillance, CTEPH monitoring if at risk, annual reassessment of duration vs bleed risk Disposition criteria: - Annual outpatient follow-up; lifelong if extended AC or CTEPH; cross-link to pulm.pe.core.v1 for any PE-specific concerns Escalation triggers (move to higher acuity): - New PE/DVT → resume indefinite AC; evaluate APS / cancer - Persistent dyspnea → V/Q + RH cath for CTEPH (refer to PH clinic per ESC 2019) - Major bleed on extended AC → reassess risk-benefit, may stop for transient-risk provoked or switch class - Pregnancy → switch DOAC to LMWH per ASH 2018
