Extensive Deep Vein Thrombosis and Pulmonary Embolism in a Young Patient With Heterozygous Factor V Leiden Mutation and Antiphospholipid Syndrome.

Although thrombotic events are uncommon in young individuals, patients with genetic mutations in coagulation factors may develop extensive multisite thrombosis. We present the case of a 26-year-old patient, a smoker for nine years, who was admitted to the hospital complaining of right thigh pain with swelling, right flank abdominal pain, dyspnea, and hemoptysis. A medical history provided by the patient indicated that one month prior to presentation, an accidental fall had resulted in multiple rib fractures, bilateral hemopneumothorax, and pneumomediastinum.
