Urinary Tract Calculi VI: Surgical Management

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Mitral Stenosis III: Medical Management

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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...

Venous Thrombosis III: Interprofessional Care

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Urinary Tract Calculi III: Medical Management

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Summary

Shockwave intravascular lithotripsy effectively treats underexpanded stents in heavily calcified coronary lesions. This technique can improve stent expansion, even in challenging chronic total occlusion cases.

Vascular Medicine
Medical Device Technology

Background:

Heavily calcified lesions pose challenges during percutaneous coronary intervention (PCI), often leading to suboptimal stent expansion and adverse outcomes.
Underexpanded stents, a known predictor of poor long-term results, can result from inadequate lesion preparation in calcified arteries.

Observation:

A case study involving a 66-year-old male with severe left anterior descending (LAD) artery calcification and significant stent underexpansion post-PCI for chronic total occlusion (CTO).
The patient experienced marked stent underexpansion due to insufficient predilatation and postdilatation during the initial procedure.

Findings:

Shockwave intravascular lithotripsy (S-IVL) was successfully employed to address the underexpanded stent.
S-IVL treatment resulted in excellent stent expansion, overcoming the limitations imposed by severe calcification.

Implications:

S-IVL demonstrates potential as a valuable tool for optimizing stent expansion in cases of acute and late underexpansion caused by severe coronary calcification.
This case suggests S-IVL may be a viable option for improving procedural success and long-term outcomes in complex PCI scenarios involving calcified lesions.
