Summary
Emergency embolization successfully treated a pelvic fracture bleeding in a patient with a rare persistent sciatic artery. Awareness of this vascular anatomy is crucial for avoiding complications during embolization procedures.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Anatomy
Background:
- Pelvic fractures can cause life-threatening hemorrhage requiring emergency embolization.
- Persistent sciatic artery is a rare congenital anomaly where the sciatic artery remains the primary artery to the lower limb.
Observation:
- A patient presented with a bleeding pelvic fracture necessitating emergency embolization.
- The patient exhibited a persistent sciatic artery, a significant anatomical variation.
Findings:
- Successful hemostasis was achieved through selective catheterization of the internal iliac artery branches.
- The embolization procedure in the presence of persistent sciatic artery was performed without complications.
Implications:
- This case highlights the critical importance of recognizing persistent sciatic artery during endovascular interventions.
- Understanding this vascular anomaly is essential for interventional radiologists and vascular surgeons to prevent procedural misadventures.
- Accurate pre-procedural imaging and anatomical knowledge are paramount for safe and effective embolization in patients with rare vascular variations.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
