Plastic and reconstructive surgery relies on the knowledge of angiosomes in the raising of microsurgical flaps. Growing interest in muscle-sparing perforator flaps calls for reliable methods to assess the clinical feasibility of new donor sites in anatomical studies. Several injection techniques are known for the evaluation of vascular territories.(More)
BACKGROUND One promising surgical treatment of lymphedema is the VLNT. Lymph nodes can be harvested from different locations; inguinal, axillary, and supraclavicular ones are used most often. The aim of our study was to assess the surgical anatomy of the lateral thoracic artery lymph node flap. MATERIALS AND METHODS In total, 16 lymph node flaps from nine(More)
Bone perfusion evaluation methods in cadaver studies have yet to be established. The aim of this report was to introduce and validate the feasibility of indocyanine green (ICG) fluorescence angiography for evaluation of bone perfusion in the femoral medial condyle in cadavers. In 4 fresh nonembalmed cadavers (2 female), the descending genicular artery was(More)
BACKGROUND Vascularized lymph node transfer is an effective surgical method in reducing lymphedema. This study provides the first detailed description of the surgical anatomy of the supraclavicular lymph node flap in regard to pedicle length, pedicle diameter, and the number of lymph nodes and their exact location inside the flap. METHODS Bilateral(More)
BACKGROUND Harvesting the submental flap for vascularized lymph node transfer (VLNT) presents a challenging procedure because of, the topographic variation of the submental artery (SA) and the marginal mandible nerve (MMN) and the limited pedicle length for a free tissue transfer. The aim of this study was to evaluate surgical anatomical landmarks and(More)
In the last decades there have been a few reports of transient changes of breast implants during air travel and travel at high altitudes. Silicone implants exposed in a hypobaric chamber at a simulated altitude of 35,000 feet, far higher than the pressure typically achieved in commercial airline cabins, showed only minimal expansion; however the idea of(More)
PURPOSE We explore the relationship of aqueductal flow of cerebrospinal fluid (CSF) and the changes of the anatomical configuration of the cerebral aqueduct (AC) in patients with communicating hydrocephalus (CH) in a routine MRI setting. METHODS/PATIENTS We performed a retrospective evaluation of different anatomical configurations of the AC on(More)
