Loupes-only microsurgery.

Standard magnification in microsurgery is accomplished with the operating microscope. Loupes are perceived by the microsurgical community as technically less safe. However, after several years of microscope-only microsurgery, most of our microvascular procedures are performed under loupes 3.5-4x. Considering our results using loupes-only microsurgery, which are comparable with those obtained when using the microscope, we suggest that loupe-aided microsurgery might represent a natural progression for the experienced microsurgeon. Microsurgical skills and experience outweigh the importance of the magnification factor. While the microscope is mandatory for replantations distal to the palmary arch, microneurosurgery, and supramicrosurgery, loupes should be used in so-called "macro-microsurgery." One may include in this category replantations down to the palmar arch and free flaps with vessels more than 1.5 mm, such as the latissimus, serratus, (para)scapular, fibula, radial forearm, rectus abdominis, dorsalis pedis, omentum, and jejunum. Before starting loupes-only microsurgery, intensive training under the microscope is crucial. Less magnification does not mean less quality.

Vascular access in chronic dialysis: a plastic surgeon's approach.

Thirty-five years after Brescia et al. (N Engl J Med 275:1089-1092, 1966) realized the first peripheral autogenous arteriovenous fistula, the "Achilles' heel" of chronic dialysis is still the absence of a good-quality permanent vascular access. The number of patients depending on hemodialysis is increasing. Until 10 years ago, in Romania, there was a need to treat isolated critical cases. Nowadays, every dialysis center needs algorithms for a standardized approach, adaptable for each case. We reviewed 171 consecutive arteriovenous fistulas (132 patients) performed in adults in identical standard conditions: use of an inflatable tourniquet during the vascular dissection, microsurgical techniques, and use of only autogenous tissues. We analyzed our results, the technical difficulties encountered, and their management in long-term follow-up. The aim of this study was to set up the basic principles of our algorithms. Our approach, based on our education as plastic surgeons involved in hand surgery and microsurgery, might present the advantage of sparing renal patients vascular capital.
