The Arch of Aorta

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Thoracic Aorta

Thoracic Aorta

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

Abdominal Aorta

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Arteries of the Upper Limbs

Arteries of the Upper Limbs

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...

Aortic Regurgitation I: Introduction

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Endovascular Interventions
Aortic Pathologies

Background:

Complex aortic pathologies, including thoracoabdominal, para-aortal, and juxtarenal aneurysms, present significant treatment challenges.
Existing endovascular techniques may be limited in cases with small aortic diameters or specific anatomical configurations.

Purpose of the Study:

To introduce and describe the semibranch as a novel tool for treating patients with thoracoabdominal, para-aortal, and juxtarenal aortic pathologies.
To evaluate the feasibility and effectiveness of the semibranch technique in complex aortic cases.

Main Methods:

The semibranch technique was applied in two patients with complex aortic pathologies.
A transfemoral approach utilizing a steerable sheath was employed for device placement.
Successful cannulation, bridging stentgraft deployment, and sealing of the semibranches were performed.

Main Results:

The semibranch technique was successfully applied in four instances across two patients.
All four deployed semibranches effectively sealed the aortic pathologies.
The procedure involved treating a type Ia endoleak after EVAR and a juxtarenal aneurysm.

Conclusions:

The semibranch represents a valuable addition to the endovascular interventionalist's toolkit.
This device is particularly beneficial for patients with small aortic diameters or limited space for standard branches.
Semibranches address limitations where fenestrations are unsuitable, such as in kinked aortas.
