The Lymphatic Microsurgical Preventing Healing Approach (LYMPHA) procedure entails performing a lymphovenous bypass (LVB) at the time of axillary lymph node dissection to reduce lymphedema risk. The two most common fluorophores utilized in LVB are blue dye and indocyanine green. We developed a novel application of fluorescein isothiocyanate for intraoperative lymphatic mapping. Our goal is to demonstrate the safety and efficacy of fluorescein isothiocyanate for this application. We reviewed a prospectively collected database on breast cancer patients who underwent LYMPHA from March to September 2015...

BACKGROUND: Management of ruptured arteriovenous malformations (AVMs) with a mass-producing intracerebral hematoma (ICH) represents a surgical dilemma. OBJECTIVE: To evaluate the clinical outcome and obliteration rates of microsurgical resection of AVM when performed concomitantly with evacuation of an associated space-occupying ICH. METHODS: Data of patients with AVM were collected prospectively. Cases were identified in which an AVM was resected and an associated space-occupying ICH was evacuated at the same time, and divided into "group 1," in which the surgery was performed acutely within 48 h of presentation (secondary to elevated intracranial pressure); and "group 2," in which selected patients were operated upon in the presence of a liquefying ICH in the "subacute" stage...

BACKGROUND: Superior cerebellar artery (SCA) aneurysms are usually grouped with aneurysms that arise from the upper basilar artery or more broadly, the posterior circulation. However, the SCA aneurysm has distinctive anatomy that facilitates safe surgical management, notably few associated perforating arteries, and excellent exposure in the carotid-oculomotor triangle. OBJECTIVE: To demonstrate the outcomes of patients treated with microsurgery in a continuous surgical series...

BACKGROUND: In this study, markers of coagulation and fibrinolysis were assessed during early and delayed microsurgical reconstruction in patients with traumatic defects of their lower legs to analyse whether an imbalance of the hemostasis after trauma might predispose the development of vascular complications. METHODS: The prospective study included 70 patients. In 35 patients, surgery was performed within 72 hours after injury. In 35 other patients, delayed free flap transfer was performed between 14-21 days after trauma...

BACKGROUND: Prolonged mean life expectancy gives rise to a more populated and older patient group. With increasing number of cases during the past decades, older patients are regarded as candidates for microsurgical interventions. Whether advanced patient age is an independent risk factor for microsurgical reconstruction is still an ongoing matter of debate. METHODS: The Cochrane Central Register of Controlled Trials, PubMed, MEDLINE, CINAHL and EMBASE databases were screened for combination of the key words "elderly", "geriatric", "advanced age", "free flap", "microsurgery", free tissue transfer" by using time limits between 1989 and 2015...

BACKGROUND: Multiple free tissue transfer from the same donor site is not well described for microsurgical head and neck reconstruction. METHODS: Between (8/2011 and 11/2012), 103 patients received 103 free ALT flaps for head and neck reconstruction; flaps were called first-time ALT flaps. Intra-operative findings were used to assess the presence of a favorable anatomy for a future second flap from the same donor site. And, between 9/2009 and 12/2013, second-time flaps from previously used anterior thighs were attempted either freely or guided by the intra-operative data from the previous surgery...

PURPOSE: Which infants with brachial plexus birth palsy (BPBP) should undergo microsurgical plexus reconstruction remains controversial. The current gold standard for the decision for plexus reconstruction is serial clinical examinations, but this approach obviates the possibility of early surgical treatment. We hypothesize that a new technique using 3-dimensional volumetric proton density magnetic resonance imaging (MRI) without sedation can evaluate the severity of BPBP injury earlier than serial clinical examinations...

BACKGROUND: The meniscus plays an important role in controlling the complex biomechanics of the knee. Meniscus injury is common in the knee joint. The perimeniscal capillary plexus supplies the outer meniscus, whereas the inner meniscus is composed of avascular tissue. Angiogenesis factors, such as vascular endothelial growth factor (VEGF), have important roles in promoting vascularization of various tissues. VEGF-mediated neovascularization is beneficial to the healing of injured tissues...

Recent studies using cone-beam computer tomography (CBCT) have added to our understanding of anatomical variation in the mandible of humans. However, the distribution of nerves cannot be revealed by CBCT. There have been investigations of the distribution of nerves relating to the mandible, but some proposed causes of these variations remain controversial. In this study, we observed a total of 10 sides from five mandibles of Macaca fascicularis of unknown age and sex using CBCT and dissection under stereomicroscopy...

Corneal transplant is the main treatment for blindness caused by corneal diseases. The common methods of corneal transplant include penetrating keratoplasty and lamellar keratoplasty. With the advances of microsurgical instruments and technology in recent years, deep anterior lamellar keratoplasty (DALK) has gradually increased. Compared with conventional penetrating keratoplasty, the optical effects of DALK are not much different, but DALK has fewer complications. So DALK is expected to become the mainstream of corneal transplantation...
