Finding Perforator "Freeway" for Design Optimization of Expanded Flaps by Indocyanine Green Angiography.

Indocyanine green angiography (ICGA) is a useful tool for the visual assessment of superficial blood flow. Herein, we used ICGA to visualize perforator branches and linking vessels to provide a road map for flap design of an expanded flap. Twenty-eight expansions were planned to use back-cut technique in 26 patients.

Extrinsic Vascular Pathway Preservation Improves Survival in a Rat Three-Territory Flap Model Based on the Deep Circumflex Iliac Artery.

Background: Extended flaps are commonly applied for large defects. However, a postoperative flap necrosis incidence of 11% to 44% remains a major complication. Previous clinical studies have shown that maintaining the extrinsic vascular pathway (EVP) can increase the survival area of extended flaps.

Inclusion of a latissimus dorsi segment in an extended lower trapezius musculocutaneous flap facilitates complex defect reconstruction.

The pedicled lower trapezius musculocutaneous flap (LTMF) can extend far beyond the lateral border of the trapezius muscle, with a reliable blood supply. However, the distal part of the extended LTMF lacks a muscular component, limiting its usage in complex defect reconstruction, which often requires obliteration of dead space and coverage of vital structures. To overcome this limitation, we modified the LTMF by adding a segment of latissimus dorsi muscle (LDM).

Periorbital and Perioral Defect Reconstruction Using the Split Pre-Expanded Medial Arm Flap Aided by Using Indocyanine Green Angiography.

The pre-expanded medial arm flap provides suitable skin for the resurfacing of a periorbital or perioral defect. However, the flap must be intraoperatively split to imitate the appearance of the oral or ophthalmic fissure, which can compromise flap perfusion. This study aimed to evaluate the safety and effectiveness of splitting pre-expanded medial arm flaps with the aid of indocyanine green angiography.

[Flap design and preliminary clinical experience of the lower trapezius musculocutaneous flap carrying a portion of the latissimus dorsi muscle].

Objective: To explore the reliability and effectiveness of soft tissue defect reconstruction using the lower trapezius musculocutaneous flap carrying a portion of the latissimus dorsi muscle.

Methods: Between December 2014 and December 2019, 13 patients underwent the reconstruction of soft tissue defects in various sites using the lower trapezius musculocutaneous flap carrying a portion of the latissimus dorsi muscle. There were 10 males and 3 females, with an average age of 52.

[Indocyanine green angiography technique assisted brachial artery perforator propeller flap to repair soft tissue defects of trunk and upper limb].

Objective: To explore the feasibility of using indocyanine green (ICG) angiography to detect brachial artery perforators, and the clinical application of brachial artery perforator propeller (BAPP) flaps to repair soft tissue defects of the trunk and upper limbs.

Methods: Between August 2016 and February 2019, ICG angiography was used to detect the perforating vessels of the brachial artery muscle septum, and the BAPP flaps were cut out with the detected perforating vessels as the pedicle to repair 19 cases of trunk and upper limb soft tissue defects. There were 12 males and 7 females, with an average age of 28.

Use of Indocyanine Green Imaging for Perforator Identification in Preexpanded Brachial Artery Perforator Flaps.

The tissues of the medial arm as a donor site for perforator flap design have several advantages. However, they are relatively underused with limited reports, partly due to unreliable perforator anatomy. Therefore, we aimed to review our preliminary experience using indocyanine green (ICG) angiography to design and elevate preexpanded pedicled brachial artery perforator (BAP) flaps for regional reconstruction.

Movement speed effects on beta-band oscillations in sensorimotor cortex during voluntary activity.

Beta-band oscillations are a dominant feature in the sensorimotor system, which includes movement-related beta desynchronization (MRBD) during the preparation and execution phases of movement and postmovement beta synchronization (PMBS) on movement cessation. Many studies have linked this rhythm to motor functions. However, its associations to the movement speed are still unclear.

[Prevalence of infection and effect of albendazole treatment among residents in two communities of Zhongshan City].

Objective: To understand the prevalence of infection among residents in two communities of Zhongshan City, and evaluate the effect of albendazole treatment, so as to offer the evidence for formulating the strategy of clonorchiasis prevention and control.

Methods: The stool specimens were collected from the residents of two comprehensive demonstration areas, and the eggs of were detected by Kato-Katz technique. Those who were tested positive were treated with albendazole (0.
