• Previous history of cerebral hemorrhage
• Brain, spinal, or ophthalmological surgery within 3 months prior to entry into this study
• Previous history of Heparin-induced thrombocytopenia
• Patients for whom anticoagulant therapy is contraindicated or who cannot be taken off anticoagulant therapy due to coexistent condition (e.g. prosthetic heart valve implant)

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Fondaparinux	Drug: Fondaparinux sodium; The dose of Fondaparinux will be determined based on a subject's body weight (< 50 kg, 5 mg; 50 to 100 kg, 7.5 mg; >100 kg, 10 mg) and administered once daily by subcutaneous (SC) injection.; Other Names: GSK576428
Other: unfractionated heparin	Drug: unfractionated heparin (UFH); UFH therapy will be started on Day 1 while adjusting activated partial thromboplastin time (aPTT) to maintain aPTT 1.5 to 2.5 times control.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Recurrent or New Symptomatic Venous Thromboembolism (VTE)	VTE (pulmonary thromboembolism [PE] and/or deep vein thrombosis [DVT]) was adjudicated blindly by the Central Independent Adjudication Committee of Efficacy (CIACE).	From Day 1 to Day 90 (±7 days)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Recurrent or New Symptomatic/Asymptomatic VTE (by Type)	VTE (pulmonary thromboembolism [PE] and/or deep vein thrombosis [DVT]) was adjudicated blindly by the CIACE.	From Day 1 to Day 90 (±7 days)
Percentage of Participants With Perfusion Lung Scan Results Scored as Improved, no Change, or Worse Compared to Baseline	Classifications of "Improved," "No change," or "Worse" were adjudicated blindly by the CIACE.	Baseline, single day between Day 5 and Day 10 (the day when the medication [FPX or UFH] was finished /discontinued) (±1 day)
Total Perfusion Score at Baseline and Mean Change From Baseline at Day 5-10	Change from baseline was calculated as the score on the day medication was finished/discontinued (anywhere from Day 5 to Day 10) minus the baseline score. The perfusion score (0: no perfusion; 0.25, 0.5, 0.75, 1: normal) in each of the six lobes of the lung was adjudicated blindly by the CIACE. Total perfusion score (r) was calculated as: r = (0.25 x right lower lobe) + (0.12 x right middle lobe) + (0.18 x right upper lobe) + (0.20 x left lower lobe) + (0.12 x lingula) + (0.13 x left upper lobe).	Baseline, single day between Day 5 and Day 10 (the day when the medication [FPX or UFH] was finished /discontinued) (±1 day)
Percentage of Participants With a Bleeding Event	Bleeding events (major bleeding [clinically overt bleeding with fatality, location in a critical organ, a fall in hemoglobin >=2 grams (g)/deciliter (dL), or a transfusion >=2 units]; minor bleeding [clinically overt bleeding and not adjudicated as major bleeding], and no bleeding) were adjudicated blindly by the Central Independent Adjudication Committee of Safety (CIACS).	Initial treatment period (from the first dose of FPX/UFH to N days after the last dose of FPX/UFH; specified based on creatinine clearance [CLcr]; N=3, CLcr >=50 mL/min; N=4, 30 =< CLcr < 50 mL/min; N=9, CLcr < 30 mL/min).
