Aortoiliac thrombosis in COVID-19 patients: A case series.

Severe acute respiratory syndrome coronavirus 2 infection has been associated with a prothrombotic state. Reports of arterial and venous thrombosis have emerged. Here, we report three cases of aortoiliac thrombosis presenting as mesenteric and lower extremity ischemia in coronavirus disease 2019 patients with no identifiable proximal embolic source or history of prothrombotic condition.

Comparative Analysis of Intranodal Lymphangiography with Percutaneous Intervention for Postsurgical Chylous Effusions.

Purpose: To evaluate clinical success and time to resolution of intranodal lymphangiography (INL) alone or with thoracic duct embolization (TDE) or thoracic duct disruption (TDD) based on initial effusion volume for postsurgical chylothorax.

Materials And Methods: Retrospective review was performed of 57 patients (mean age 63 y; 65% male) undergoing INL alone or in conjunction with other percutaneous techniques for postsurgical chylous effusions. INL alone was performed when chylothorax output was ≤ 500 mL/d and no leak was identified during fluoroscopy.

CT-Fluoroscopic Cervical Transforaminal Epidural Steroid Injections: Extraforaminal Needle Tip Position Decreases Risk of Intravascular Injection.

Background And Purpose: Cervical transforaminal epidural steroid injections are commonly performed for temporary pain relief or diagnostic presurgical planning in patients with cervical radiculopathy. Intravascular injection of steroids during the procedure can potentially result in cord infarct, stroke, and even death. CT-fluoroscopy allows excellent anatomic resolution and precise needle positioning.
