Cardiac Catheterization IV: Nursing Management

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Cardiac Catheterization III: Left Heart Catheterization

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Cardiac Catheterization II: Right Heart Catheterization

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Summary

This summary is machine-generated.

This study presents a novel endovascular technique for treating rare proximal basilar artery aneurysms. Reconstructing the fenestrated artery with stents enables safe coiling of wide-necked aneurysms.

Area of Science:

Endovascular neurosurgery
Cerebrovascular surgery
Interventional neuroradiology

Background:

Proximal basilar artery aneurysms are uncommon cerebrovascular lesions.
These aneurysms frequently occur with fenestrated basilar arteries.
Endovascular approaches are often suitable for treating these aneurysms.

Observation:

A 48-year-old female patient presented with a proximal basilar artery aneurysm.
The treatment involved reconstructing a fenestrated basilar artery using two stents in an X-configuration.
The wide-necked aneurysm was subsequently coiled, achieving successful occlusion.

Findings:

The endovascular reconstruction and coiling procedure were technically successful.
The patient experienced no new neurological deficits post-procedure.
Follow-up at 15 months showed no evidence of aneurysm recanalization.

Implications:

This stent-assisted coiling technique provides a viable treatment option for wide-necked aneurysms in fenestrated basilar arteries.
It avoids the potential complications of sacrificing a physiologically significant branch of the fenestrated artery.
This method offers an alternative to open surgical repair for complex basilar artery aneurysms.
