The use of a microanastomotic device for direct connection of intracranial vessels can be helpful to facilitate removal of distally located middle cerebral artery (MCA) aneurysms. The authors report on two patients who presented for treatment with large aneurysms distally located on the MCA. The aneurysms were completely excised and the proximal and distal portions of the parent vessel were connected in an end-to-end fashion by using a microanastomotic device. The time required to crossclamp the vessel for excision of the aneurysm and primary anastomosis was 10 minutes in one case and 15 minutes in the other. The short crossclamp time and high-quality anastomosis afforded by this device may be useful in the treatment of these difficult lesions and the prevention of cerebral ischemia.

Mobile Smartphone Thermal Imaging Characterization and Identification of Microvascular Flow Insufficiencies in Deep Inferior Epigastric Artery Perforator Free Flaps.

Background: Mobile smartphone thermal imaging (MTI) devices correlate with blood flow, which makes them appealing adjuncts during reconstructive surgery. MTI was assessed in the setting of deep inferior epigastric artery perforator (DIEAP) free flaps. We hypothesized that MTI can be a surrogate for blood flow to identify microvascular flow insufficiencies.

While a simple interrupted sutured anastomosis remains the gold standard in microsurgery, the introduction of the microanastomotic coupler device (MACD) has decreased procedure time and thrombosis risk, and improved the patency of venous anastomoses. The aim of this review is to update the evidence-based advantages of the MACD on arteries, based on clinical and experimental data, and to compare them to the hand-sewn approach in free flap transfer. All relevant articles that appeared in the PubMed and Medline/Ovid databases during the past three decades were reviewed.

The radial forearm flap is one of the most used micro-anastomotic flaps in cervicofacial reconstruction in a carcinological context. This flap is an ideal in terms of reliability and fineness; it has, however, some disadvantages in terms of the functional and aesthetic complications of its donor site. In alternative to a radial forearm free flap, we report the use of the free super thin external pudendal artery flap (STEPA flap) for an oropharyngeal reconstruction.

Background: The timing of surgical reexploration in microanastomotic thrombosis is directly related to the salvage rate of free flap. Near-infrared spectroscopy (NIRS) is a noninvasive technique, which allows a continuous bedside monitoring of flap oxygenation. The current literature is lacking in the assessment of variables able to modify the NIRS monitoring.

Microvascular flap reconstruction is known as successful technique, although vascular thrombosis can cause free flap failure. To analyze the histologic characteristics and causes of free flap failure, this clinical study examined failed free flaps, including the microanastomosed sites. This study included a total of 5 failed flaps, including 3 radial forearm free flaps, 1 latissimus dorsi free flap, and 1 fibular free flap, all performed with microvascular reconstruction surgery from 2009 to 2011 at Seoul National University Dental Hospital.
