Techniques of Impella removal while preserving arterial access
1University of California, San Diego Sulpizio Cardiovascular Center, United States.
Summary
Maintaining arterial access after removing large mechanical circulatory devices (MCD) is difficult. This paper presents two new techniques and reviews literature on arterial access site preservation following Impella removal.
Area of Science:
- Cardiology
- Vascular Surgery
- Medical Device Technology
Background:
- Large caliber mechanical circulatory devices (MCD) are increasingly used for hemodynamic support.
- Arterial access site management after MCD removal presents significant clinical challenges.
- Standardized protocols for arterial access site preservation post-MCD are lacking.
Observation:
- The removal of large-bore arterial access sheaths used for MCDs can lead to complications.
- Hemorrhage and pseudoaneurysm formation are common concerns at the arterial access site.
- Current literature offers limited guidance on optimal techniques for managing these access sites.
Findings:
- Two novel techniques for arterial access site preservation after Impella removal are described.
- The described techniques aim to minimize complications and ensure vascular integrity.
- A comprehensive review of existing literature on post-MCD arterial access management is provided.
Implications:
- The presented techniques may offer improved outcomes for patients requiring large caliber arterial access.
- Enhanced understanding of arterial access site maintenance can guide clinical practice.
- Further research is warranted to validate the efficacy and long-term safety of these novel approaches.

Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Arteries, the vasculature responsible for transporting blood from the heart, possess robust walls capable of enduring the elevated pressures exerted by the heartbeat. Arteries near the heart are especially thick-walled and enriched with elastic fibers across their three tunics, classifying them as elastic or conducting arteries. These arteries, usually with a diameter exceeding 10 mm, are characterized by their ability to dilate in response to the blood pumped from the heart's ventricles...

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...

The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...
