: Increasing focus on reducing morbidity from latissimus dorsi flaps has led to the evolution of muscle-sparing variants and perforator-based flaps. This study aimed to investigate the vascular anatomy of the muscle-sparing variant and to describe its application as a free flap based on the descending branch of the thoracodorsal artery.
: Twelve fresh cadavers underwent anatomical dissection and angiographic injection studies of the thoracodorsal arterial system. The musculocutaneous territories of the descending and transverse branches to the latissimus dorsi muscle were identified and assessed using three-dimensional reconstruction software of computed tomography imaging results. In the clinical study, five patients underwent reconstruction of a variety of defects using the free descending branch muscle-sparing latissimus dorsi flap.
: Three- and four-dimensional (computed tomography) angiography demonstrated perfusion of the latissimus dorsi muscle by the transverse and descending branches, with overlap of vascular territories via cross-linking vessels. The descending branch supplied a slightly greater cutaneous area overlying the muscle, although differences between both branches were not significant (p = 0.76). In the clinical study, the free muscle-sparing latissimus dorsi flap provided excellent coverage with no flap complications or seroma.
: The free muscle-sparing latissimus dorsi flap based on the descending branch of the thoracodorsal artery is a viable reconstructive option. Significant collateral flow between vessels allows for larger flap harvest than would be expected. The flap is technically simple to harvest, provides a large perfusion area, and is a reliable variant of the full latissimus dorsi flap.

[Show abstract][Hide abstract] ABSTRACT: Multiple causes at any level between the brain and the bladder can lead to diminished voiding efficiency and bladder acontractility. Treatment options for patients with an acontractile bladder have been limited as most patients were forced to perform lifelong self-catheterization at the moment. The latissimus dorsi detrusor myoplasty (LDDM) is a recent and promising therapeutic surgical option to restore adequate bladder emptying on demand. This article critically reviews the available literature on LDDM and focuses particularly on the preoperative diagnostic evaluation and patient selection, treatment outcome and the postoperative contractility measurement.

[Show abstract][Hide abstract] ABSTRACT: The purpose of this study was to explore the effectiveness and safety of three-dimensional (3D) digitalized planning for the sural neurovascular island flap in repair of soft tissue defects in the ankle and foot.
This study included 40 patients with soft tissue defects of the ankle and foot who underwent soft tissue reconstruction between October 2008 and June 2012. The patients were randomly assigned into two groups: 3D-reconstruction group (Group A, n=20) and control group (Group B, n=20). Three-dimensional, digitalized virtual planning was performed in the patients in Group A, who underwent computed topographic angiography. The survival rate, operation time, and surgical accuracy were compared between the two groups.
All flaps in Group A survived and the recipient site primarily healed, but 4 flaps in Group B had marginal necrosis after the operation. During the 6-12 month follow-up period, all flaps in Group A had good skin quality. In Group B, hard scarring and mild contracture occurred in 4 cases, and the patients experienced pain when walking. The survival rate of the flap in Group A (100%) was significantly higher than in Group B (70%). The operation time in Group A was significantly less than in Group B. The surgical accuracy in Group A was significantly better than in Group B.
The preoperative use of 3D digitalized virtual planning for the sural neurovascular island flap improves the surgical accuracy, decreases the operation time, and increases the survival rate of the flap.

[Show abstract][Hide abstract] ABSTRACT: This article highlights reconstructive principles in flap selection, use, and insetting to optimize functional and aesthetic outcomes after upper extremity reconstruction. The concept of respecting the aesthetic units of the hand during reconstruction is discussed. A current literature review of the aesthetic outcomes using various flaps, such as fasciocutaneous, fascia only, and muscle flaps, is provided. An approach based on aesthetic unit principles to upper extremity reconstruction is also highlighted to help optimize outcomes.
