Extensive Iliocaval Deep Vein Thrombosis Provoked by Coronavirus Disease 2019 (COVID-19) in the Setting of an Inferior Vena Cava Filter

Thrombotic events are well-known complications of coronavirus disease 2019 (COVID-19). Inferior vena cava filters (IVCF) are devices used to prevent pulmonary embolism (PE) and also increase the risk of thrombotic complications. Here, we describe the case of a 38-year-old female with extensive bilateral lower extremity deep vein thrombosis (DVT) and thrombosis of the infrarenal inferior vena cava (IVC) in the setting of an IVCF and symptomatic COVID-19. The IVCF had been placed a few months prior for a left femoral DVT and PE after spinal surgery. This patient was treated with pharmacomechanical thrombectomy and ultrasound-assisted thrombolysis followed by angioplasty and anticoagulation. The IVCF was retrieved after confirming there was no residual DVT when the patient recovered from COVID-19 infection. This case of a rare combination of IVCF-related thrombosis secondary to COVID-19 highlights the potential pitfalls of IVCF in this situation.

Extensive Postpartum Upper and Lower Extremity Deep Vein Thrombosis in a Patient With a History of Preeclampsia

We describe the case of a 19-year-old woman with no significant medical history who developed progressive right-sided neck pain and palpitations one month following a pregnancy complicated by preeclampsia. Family history was significant for unprovoked deep vein thrombosis (DVT) and pulmonary embolism (PE) in her father at age 44. Systemic examination revealed mild swelling of the right upper extremity with pain on palpation. Computed tomography (CT) of the thorax with contrast demonstrated extensive occlusion of right upper extremity veins and collateralization of chest wall veins. Pulmonary emboli were present bilaterally in the segmental and subsegmental branches of the lower lobe pulmonary arteries. CT of the abdomen with contrast revealed thrombi in the left common and external iliac veins. Thrombophilia screening was normal. The patient was treated with enoxaparin and ampicillin/sulbactam. Her clinical condition improved, and she was discharged with an outpatient clinic follow-up appointment.
