Objective: To investigate female iliac vein variations by using the computed tomography angiography (CTA) three-dimensional (3 D) reconstruction technique.
Methods: We retrospectively studied 1623 patients undergoing abdominal and pelvic CTA scanning for gynecological diseases from December 2009 to December 2018. Accurate digital 3 D models of the iliac vein were constructed using Mimics 19.0 software and used to study the morphology and variations. Variations in the common iliac vein (CIV), external iliac vein (EIV) and internal iliac vein (IIV) were classified as type I, abnormal number of veins; type II, abnormal communicating branches; or type III, other variations.
Results: The overall variation rates of the iliac vein and CIV were 51.57% (837/1623) and 20.33% (330/1623), respectively. The main type of CIV variation was type II. The main type I CIV variation was the absence of the CIV (98.15%), which mostly occurred on the right side (64.81%, 35/54). Type II CIV variation was the most common, with abnormal communicating branches between the left CIV and right IIV (81.78%, 211/258). The overall variation rates of the EIV and IIV were 36.66% (595/1623) and 49.60% (805/1623), respectively, mainly on the right side. The main type of variation was type I. Among them, the division of the IIV into two branches plus convergence with the ipsilateral EIV was the most common (22.98%, 373/1623).
Conclusion: In this study, approximately half of the patients had iliac vein variations. The preoperative identification of iliac vein variation may reduce vascular injury in pelvic surgery.

Tuberculosis (TB) is a multisystem infectious disease with both pulmonary and extrapulmonary manifestations. TB can also induce a hypercoagulable state, setting off a cascade of changes in the body, including systemic inflammation, endothelial dysfunction, and abnormalities in the coagulation and fibrinolytic pathways. Collectively, these factors significantly increase the risk of venous thromboembolism, such as deep vein thrombosis and pulmonary embolism.

Purpose: Pelvic ring fractures involving the iliopubic rami can cause functional impairment. Percutaneous retrograde fixation is a less invasive procedure when compared to traditional open approaches, however precise anatomical knowledge is crucial for safe screw placement. This study aims to describe the morphology of the iliopubic rami, define a safety corridor for percutaneous screw fixation, specially focusing on the relationships between the iliopubic rami and neurovascular structures.

Intravenous leiomyomatosis with intracardiac extension is a rare benign tumor originating from uterine smooth muscle. A 50-year-old woman presented with a cardiac mass 3 years after hysterectomy. Imaging revealed a tumor extending from the right internal iliac vein to the right atrium.

A 49-year-old female presented with subacute onset of severe worsening bilateral lower extremity swelling. Bilateral iliac venous thrombus and extensive thrombus of the inferior vena cava with extension to the right atrium and bilateral segmental pulmonary emboli was identified on imaging. She was initiated on therapeutic anticoagulation prior to undergoing percutaneous mechanical thrombectomy with the RevCore TM device (Inari Medical, Irvine, CA) with retrieval of white, relatively well-formed organized clot vs mass.

Objective: To evaluate the feasibility, safety, and clinical applications of ultrasound-guided direct percutaneous access to ectatic abdominal veins for the embolization of vascular malformations.
Methods: The medical records, imaging studies, and procedural details were retrospectively reviewed for patients who underwent embolization procedures for vascular malformations with ultrasound-guided percutaneous access to intraabdominal veins, including pelvic, retroperitoneal, and portomesenteric veins.
Results: A total of 38 direct percutaneous vein accesses were performed across 25 procedures in 9 patients (age range: 3-58 years).
