INTRODUCTION: Most patients with acute Paget-Schroetter syndrome (PSS) present in one of two manners: (1) thrombosis managed initially with thrombolysis and anticoagulation and then referred for surgery, and (2) initial treatment with anticoagulation only and later referral for surgery. Definitive benefits of thrombolysis in the acute period (the first 2 weeks after thrombosis) over anticoagulation alone have not been well reported. Our goal was to compare patients managed with early thrombolysis and anticoagulation followed by first rib resection (FRR) and later postoperative venography with venoplasty (PTA) with those managed with anticoagulation alone followed by FRR and PTA using vein patency assessed with venography and standardized outcome measures. METHODS: We reviewed a prospectively collected database from 2000 to 2019. Two groups were compared: those managed with early thrombolysis at our institution (Lysis) and those managed with anticoagulation alone (NoLysis). All patients underwent FRR. Venography was routinely performed before and after FRR. Standardized outcome measures included Quick Disability of Arm, Shoulder, and Hand (QuickDASH) scores and Somatic Pain Scale. RESULTS: A total of 50 Lysis and 50 NoLysis patients were identified. Pre-FRR venography showed that thrombolysis resulted in patency of 98% of veins, whereas 78% of NoLysis veins were patent. After FRR, postoperative venography revealed that 46 (92%) patients in the Lysis group and 37 (74%) patients in the NoLysis group achieved vein patency. Thrombolysis was significantly associated with final vein patency (odds ratio: 17 [4-199]; P < .001). Lysis patients had a trend toward lower QuickDASH scores from pre-FRR to post-FRR compared with NoLysis patients with a mean difference of -16.4 (±19.7) vs -5.2 (±15.6) points (P = .13). The difference in reduction of Somatic Pain Scale scores was not statistically significant. CONCLUSIONS: Thrombolysis as initial management of PSS, combined with anticoagulation, followed by FFR and VenoPTA resulted in improved final vein patency and may lead to an improved functional outcome measured with QuickDASH scores. Therefore, clinical protocols using thrombolysis as initial management should be considered when planning the optimal treatment strategy for patients with acute PSS.
