⁣Open Heart Surgery: Aortic Root and Valve Replacement (Bentall Procedure)

This operation was performed by George Lazopoulos in the University Hospital of Heraklion Crete.

The Bentall procedure is a type of open-heart surgery to replace the aortic valve and aortic root. As mentioned in the beginning of the video, this patient presented to our department with dyspnea on exertion and was transferred to the OR to undergo a Bentall Procedure. Everyhting went well during the operation and the patient had an uneventfull recovery.

Digital mucous cysts (DMCs) are benign ganglion cysts of the digits, typically located at the distal interphalangeal (DIP) joints or in the proximal nail fold. They usually occur on the hands, although they have also been noted on the toes. The etiology of these cysts is uncertain but may involve mucoid degeneration. Often, these cysts are asymptomatic and do not require treatment. When treatment is indicated, medical therapies and surgical interventions of varying magnitudes may be attempted. Recurrence is common.

Historically, little attention has been directed at studying these cysts despite their frequency. In the literature, they have been referred to as cystomata, myxomatous cutaneous cysts, myxomatous degenerative cysts, periarticular fibromas, synovial lesions of the skin, periungual ganglions, mucous cysts, myxoid cysts, synovial cysts, dorsal cysts, nail cysts, cystic nodules, digital mucoid cysts, digital myxoid cysts, and digital mucinous pseudocysts.

Hippocrates first appreciated ganglion cysts, describing a knot of tissue full of fluid. In 1746, Eller concluded that ganglia formed from the herniation of the synovial lining of a joint. In 1882, Hyde first described the digital mucous cyst. In 1893, Ledderhose suggested that ganglia arose spontaneously in the subcutaneous tissue. In 1895, Ritschel proposed the earliest formulation of the theory that mucoid degeneration may be responsible for digital mucous cysts; Carp and Stout popularized the theory in 1928. Then, in 1947, Anderson reported that cysts caused the nail deformities.

The mechanism of formation of digital mucous cysts is unknown. Currently, it is believed that the cysts arise from mucoid degeneration of connective tissue and that this process, in most cases, involves communication with the adjacent DIP joint and possible coexistence of osteoarthritis. Clinical and radiographic evidence of osteoarthritis is common at the site of the cysts,[1] and the frequent presence of osteophytes and spurring of the DIP joint were recognized in the 1970s. Active connection to the joint space may or may not exist, as the mucoblasts associated with the cyst appear capable of sustaining the process.

Ganglia are the most common tumor or cyst of the hand. They account for approximately 70% of all such tumors or cysts, with digital mucous cysts comprising 10-15% of the total.

Women are affected more often than men (female-to-male ratio of 2-2.5:1).

⁣ ganglion cyst or synovial cyst or myxoid cyst, also known as a Bible cyst or Bible bump, is a non-neoplastic soft tissue lump that may occur in any joint, but most often occurs on or around joints and tendons in the hands or feet. It is caused by leakage of fluid from the joint into the surrounding tissue.
A ganglion cyst is a noncancerous lump that most commonly develops in the wrist or hand. Some occur in the ankles or feet. If a ganglion cyst presses on a nerve, it may be painful. Depending on its location, a ganglion cyst may restrict movement.
Ganglion cysts are noncancerous lumps that most commonly develop along the tendons or joints of your wrists or hands. They also may occur in the ankles and feet. Ganglion cysts are typically round or oval and are filled with a jelly-like fluid.
This is a surgical video displaying removal of a dorsal wrist ganglion cyst.
