Combination of High Ligation and Intraoperative Embolization Using Polidocanol for Treatment of Varicoceles
0 Views •
2023
To reduce the postoperative recurrence rate of varicocelectomy, we combined high ligation of varicocele with intraoperative embolization. We injected polidocanol from the spermatic vein during surgery to embolize the branches of the spermatic vein and collateral veins. This is an alternative surgical method for the treatment of varicocele.

2025
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Pulmonary Embolism I: Introduction

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...

A breast cancer brain metastasis mouse model is established with ultrasound imaging-guided intracardiac injection of MDA-MB231/Br-GFP cells. Development of multifocal intracranial metastases has been monitored longitudinally using high-resolution 9.4 T MRI.
FAQs
Three interacting conditions promote thrombus formation: blood stasis, endothelial injury, and hypercoagulability. Stasis allows blood to remain in place, while endothelial injury and a hypercoagulable state favor clot development. When these influences occur within a cardiac chamber, they create the conditions for an embolic mass to form, making assessment of underlying circumstances important to clinical interpretation.
An embolus’s route depends on where it originates and which circulation it enters. A mass arising on the pathway to the lungs can produce pulmonary consequences, whereas one entering the systemic circulation may reach vital organs. Passage through a septal defect can alter the expected route, so cardiac anatomy is central to interpreting potential embolic destinations.
Location determines whether the mass primarily obstructs flow within the heart or continues into another vascular bed. Obstruction can produce hemodynamic compromise, while onward travel may result in pulmonary embolism or systemic injury such as stroke. This distinction explains why identifying both the embolus and its pathway matters when clinicians assess urgency and potential consequences.
Echocardiography and other imaging methods help clinicians determine whether an intracardiac thrombus is present and where it is located. That information supports evaluation of possible obstruction or onward movement and provides a basis for selecting a management strategy. Imaging therefore contributes both to recognition of the condition and to decisions about subsequent intervention.
The findings can help guide several treatment paths, including anticoagulation, thrombolysis, or removal by surgery or catheter-based techniques. These options address the embolic mass through different strategies, so imaging is clinically useful beyond detection. It links the observed intracardiac lesion with a response aimed at limiting obstruction, migration, or resulting organ injury.
Early recognition matters because an intracardiac embolic mass may obstruct blood flow, migrate through the pulmonary or systemic circulation, or cause hemodynamic compromise. Prompt identification allows clinicians to consider anticoagulation, thrombolysis, or surgical and catheter-based removal before consequences worsen. In practice, the major goals are reducing the risk of stroke, pulmonary embolism, and circulatory instability.
