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...

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Given the overwhelming amount of information captured by the sensory organs, it is crucial that the brain is able to prioritize the processing of certain stimuli, to spend less effort on what might not be currently important and to attend to what is. One heuristic the brain uses is to ignore stimuli that are frequent or constant in favor of stimuli that are unexpected or unique. Therefore, rare events...
FAQs
The obstructing material influences both the clinical pattern and the response that clinicians consider. Blood clots, air, fat, and other material can travel to different vascular territories, so the consequences are not uniform. Identifying the likely material helps frame diagnostic evaluation and supports selection between anticoagulation, another targeted treatment, or prevention-focused management when appropriate.
Vessel location and blockage extent determine how severely tissue perfusion is compromised. A small obstruction in one territory may produce a different presentation from a more extensive obstruction elsewhere, even when both are embolic events. This relationship explains why clinicians interpret symptoms alongside the suspected vascular territory and assess the affected organ rather than relying on a single symptom pattern.
Ischemic stroke, pulmonary embolism, and systemic arterial occlusion illustrate why embolic events must be considered across multiple vascular beds. The same broad complication can affect the brain, lungs, or systemic circulation, with evaluation guided by the organ involved. This comparison broadens clinical recognition and helps connect the suspected site of obstruction with the appropriate diagnostic and treatment pathway.
Rapid recognition is important because ongoing obstruction can compromise tissue perfusion while the affected organ remains at risk. Evaluation therefore combines clinical recognition with diagnostic imaging and assessment of the likely vascular territory. In practice, this approach helps clarify the obstruction’s location and extent, supporting timely risk assessment and targeted management.
Diagnostic imaging is used to investigate where the obstruction lies and how extensively blood flow may be affected. These findings are interpreted with the patient’s symptoms and the involved organ, because location and extent influence the clinical consequences. The resulting picture supports risk assessment and helps clinicians determine whether anticoagulation or another targeted treatment should be considered.
Management depends on the clinical context rather than a single universal intervention. Anticoagulation may be used when appropriate, while other targeted treatments may be selected for particular presentations. Risk assessment helps align treatment with the event’s characteristics, and preventive strategies address patients with conditions that promote clot formation or embolization as part of ongoing care.
Conditions that promote clot formation or embolization increase concern for recurrent or future vascular obstruction. For that reason, medical evaluation extends beyond the acute episode to identify relevant risk and plan preventive strategies. This context is important when deciding how risk should influence the broader management plan, including consideration of anticoagulation or another appropriate approach.
