Summary
Percutaneous endoscopic thoracic discectomy (PETD) is a safe and effective minimally invasive treatment for upper and midthoracic disc herniation. This study demonstrates significant improvements in pain and function for patients undergoing this procedure.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
Background:
- Percutaneous endoscopic thoracic discectomy (PETD) is established for lower thoracic disc herniations.
- Technical feasibility and outcomes for upper and midthoracic disc herniation remain largely unreported.
Purpose of the Study:
- To evaluate the feasibility and clinical outcomes of PETD for symptomatic upper and midthoracic disc herniation.
- To assess the safety and efficacy of a minimally invasive approach for thoracic disc disease.
Main Methods:
- Fourteen patients with upper/midthoracic disc herniation underwent PETD under local anesthesia and sedation.
- A transforaminal approach with foraminoplasty was utilized.
- Outcomes assessed via Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), and modified MacNab criteria.
Main Results:
- All 14 patients demonstrated statistically significant postoperative improvements in VAS (7.3 to 2.3) and ODI (53.5 to 16.9) (p<0.05).
- Procedures were performed at T2-3 (n=4), T3-4 (n=5), and T5-6 (n=5).
- Mean follow-up was 43.4 months with no serious complications reported.
Conclusions:
- PETD is a technically feasible and effective minimally invasive treatment for upper and midthoracic disc herniation.
- The procedure offers favorable clinical results and a good safety profile.

01:15Thoracic Aorta
1.6K
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,...

01:17The Thoracic Cage: Sternum
5.9K
The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12).
The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid...

01:20The Thoracic Cage: Ribs
8.4K
Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal...

01:12Arteries of the Upper Limbs
2.2K
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...

01:24Pressure Relationships in Thoracic Cavity
6.3K
Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs...

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
