Purpose  

Previous studies of cutaneous perforators of the peroneal artery have shown great variability, and attest to the significant anatomical variability in this region. Furthermore, the vascular anatomy of the region has been considered unreliable in the prediction of ideal perforator topography. Preoperative imaging has been suggested as a means for improving preoperative awareness, with Doppler ultrasound and eco-colour (duplex) ultrasound as useful tools. Multi-detector row computed tomographic angiography (CTA or angio CT), has emerged as a significant improvement, providing non-invasive operator-independent details of the vascular anatomy. We utilised this tool to perform an in vivo, anatomical study of the peroneal artery perforators, and demonstrating the usefulness of CTA in planning the osteocutaneous free fibula flap.  相似文献

Arterial anatomy of the lateral orbital and cheek region and subsequently of the “peri-zygomatic perforator arteries” flap is described, based upon the dissection of the 24 human cadaver head halves. Each specimen was dissected in subdermal, first fascial and deep level. The subdermal vascular network of lateral orbital and cheek region, its orientation and contributing arteries were studied. Origin, perforation sites and diameters of transverse facial, zygomaticoorbital, zygomaticofacial and zygomaticotemporal arteries were also described and measured. Our findings support the view that the cheek island flap used for lower eyelid is a reverse flow axial pattern flap. It includes arterioles of the transverse facial artery, which are part of the subdermal vascular plexus and are uniformly longitudinally oriented. The flap receives its blood supply via perforators of the zygomaticoorbital, zygomaticofacial and zygomaticotemporal arteries, which are connected via their terminal branches with transverse facial artery.  相似文献

The anterior abdominal wall integument is frequently used in a range of reconstructive flaps. These tissues are supplied by the deep and superficial inferior epigastric arteries (DIEA and SIEAs) and the deep and superficial superior epigastric arteries (DSEA and SSEAs). Previous abdominal wall surgery alters this vascular anatomy and may influence flap design. One hundred and sixty‐eight patients underwent abdominal wall computed tomographic angiography (CTA) for preoperative imaging. Fifty‐eight of these patients had undergone previous abdominal surgery, and were assessed for scar pattern and relationship to the course and distribution of all major axial vessels and perforators. Two cadaveric abdominal wall specimens with midline abdominal scars underwent contrast injection of the DIEAs and DSEAs, with subsequent CTA. The course and distribution of all cutaneous vessels were assessed. In all clinical and cadaveric cases, the vasculature of the abdominal wall had been altered by previous surgery. In the clinical cases, vascular architecture was universally altered in the region of the scar, often modifying the filling patterns of the abdominal wall and occasionally precluding the use of an abdominal wall flap. In both cadaveric specimens, regions of non‐filling were evident upon contrast injection, highlighting the angiosomes not supplied by the DIEA or DSEA. Previous abdominal wall surgery necessarily alters the vascular architecture of the abdominal wall, and may alter the source vessels supplying cutaneous tissues. CTA was useful in identifying and delineating these changes, and may be used as a preoperative tool in this role. Clin. Anat. 22:815–822, 2009. © 2009 Wiley‐Liss, Inc.  相似文献

The abdominal wall integument is becoming the standard donor tissue for postmastectomy breast reconstruction, with its vascular supply of key importance to the reconstructive surgeon. Refinements in tissue transfer, from pedicled to free flaps and musculocutaneous to perforator flaps, have required increasing understanding of finer levels of this vascular anatomy. The widespread utilization of the deep inferior epigastric artery (DIEA) perforator flap, particularly for breast reconstruction, has rekindled clinical interest in further levels of anatomical detail, in particular the location and course of the musculocutaneous perforators of the DIEA. Advances in operative techniques, and anatomical and imaging technologies, have facilitated an increase in this understanding. The current review comprises an appraisal of both the anatomical and clinical literature, with a view to highlighting the key anatomical features of the abdominal wall vasculature as related to reconstructive flaps.  相似文献

The introduction of perforator flaps represented a significant advance in microsurgical reconstruction. However, confusion has developed due to the erroneous belief that perforator flaps are different from conventional flaps. The concept of the perforator is not new, but is an idea that evolved from the conventional flap. In fact, some of the flaps used by microsurgeons were perforator flaps. The only difference is the anatomical level of the blood vessels involved; the perforator concept is focused on the distal circulation, so-called ''perforator''. Therefore, thinner sections of tissue can be taken from the conventional donor sites of myocutaneous flaps. With the use of perforators, there are no longer "flap of choice" for specific reconstructions, because conventional donor sites have become universal donor sites, enabling the harvesting of a variety of flaps. Moreover, depending on the surgeon''s ability, any flap can be utilized as a perforator-based island flap whose source vessel has been completely preserved. Therefore, tissues can be efficiently customized and tailored into any configuration required for reconstruction. The application of perforator flap technique enables more precise dissection, and allows more selective harvesting of thinner flaps, which will expand options in reconstructive surgery. No doubt the technique will continue to evolve.

Background  Image-guided stereotaxy is a recent advancement in imaging technology, allowing computer guidance to aid surgical planning and accuracy. Despite the use of multiple techniques for patient registration in several surgical specialities, only fiducial marker registration has been described for use in soft tissue reconstructive surgery. The current study comprises an evaluation of the current techniques available for this purpose. Methods  A cohort of nine consecutive patients planned for elective free flaps were recruited, with the first five patients (four for the abdominal wall and one anterolateral thigh donor site) undergoing fiducial marker registration with a variable number of fiducial markers in order to determine the optimal number of fiducial markers to be used. Four subsequent patients undergoing perforator flap surgery underwent registration using three available registration modalities: fiducial marker registration, surface matching pointer/landmark and surface matching laser registration. Results  For the abdominal wall, registration was not able to be achieved with five fiducial markers, and was successfully achieved in all cases with either six or seven fiducial markers. For the anterolateral thigh, registration was achieved with either nine or ten markers. The four patients who also underwent surface-landmark registration and ‘Z-touch’ laser surface matching registration all failed the registration process. Conclusion  Stereotactic navigation is a useful adjunct to the preoperative imaging of perforator flaps. Fiducial marker registration was able to be achieved in all cases, can be successfully achieved with a low and predictable number of fiducial markers, is highly accurate, and was the only reliable registration process in our experience.

Background

To delineate the distribution and course layer of the perforator vessels using a modified technique.

Methods

Twelve perforator flaps were obtained from the crura of six fresh adult cadavers. The flaps were randomized into three groups (n = 4 per group): the full-thickness flap group; the deep fascia-free flap group, and the subcutaneous adipose layer-free group. The flaps were smoothened on a silk screen on a batten frame and the isolated flaps were perfused at a perfusion pressure of 140 mmHg for 10 min via the trunk of the posterior tibial artery. Perforator flaps were photographed using a digital camera and radiographed using a mammography device. The imaging data were processed by digital software system.

Results

The mean number of the posterior tibial artery perforator was 4.17 ± 0.94. The three relatively constant perforators varied in the projection points as well as the diameter and the length. The vascular branches and courses of the perforators were clearly visible on the mammograms. Elimination of all the deep fascia or the subcutaneous adipose tissues in the distal portion had no significant impact on the blood supply of posterior tibial artery perforator flaps while the vascular areas of the artery perforators were significantly reduced after the subcutaneous adipose tissue was eliminated in the proximal portion.

Conclusions

We developed an effective modified technique for delineating the vascular territory on perforator flaps of different thicknesses. Our results provide significant guidance for clinical surgeons by providing them with more detailed anatomical knowledge of perforator flaps.

With the increasing popularity of perforator flaps as “musculocutaneous flaps without muscle,” a new interest in the intercostal vessels as source vessels for perforator flaps has arisen. In a recent study, the branches of the three lowermost intercostal vessels to the latissimus dorsi were studied in detail. Now that these muscular branches are well understood, the present study examines how many of these branches reach the overlying skin as musculocutaneous perforators. We identified the intercostal artery perforators in the ninth, tenth, and eleventh interspaces, in 42 hemithoraces. Only branches that measured 0.5 mm or more in external diameter were included. The course of the perforators was followed from their exit from the latissimus dorsi muscle up to the entrance at the undersurface of the skin. This entrance point was punctured by a pin and thus marked on the skin. This study showed that at least three musculocutaneous perforators were present over the intercostal spaces IX–XI in every dorsal hemithorax (average 8 ± 3, range 3–16). Potentially, each of these vessels can be used as a pedicle for a separate perforator flap, leaving the more proximal parts of the latissimus dorsi intact for a second flap based on the dominant thoracodorsal vessels.

Abstract: Although abdominal perforator flaps based on a cutaneous branch of the deep inferior epigastric artery (DIEP flaps) have many advantages, preparing these flaps is technically difficult and requires great skill, especially as the portion of the artery running under the anterior rectus abdominis sheath must be operated upon “blind”. To allow easier preparation and elevation of a DIEP flap pedicle, we propose that the arterial perforator should: 1) be more than 1.0 mm large; 2) run a straight intramuscular course, parallel to the rectus abdominis m. fibers, with no large muscular branches; and 3) have only a short portion running immediately under the anterior rectus abdominis sheath. We examined 329 perforators (more than 0.5 mm in diameter at the anterior sheath) in 66 rectus abdominis mm. from 33 cadavers among them: 1) 52 “large” perforators were over 1.0 mm in diameter; 2) 107 “suitable” perforators ran parallel to the muscle fibers without giving off large muscular branches; and 3) 35 “ideal” perforators combined these characteristics. The ideal perforators were usually located in the mid-abdominal region, 10-30 mm lateral to the umbilicus. The suitable perforators were usually present, often in combination with the ideal perforator(s), in a restricted area 20 mm cranial and 40-50 mm lateral to the umbilicus. We classified the course and ramification pattern of the deep inferior epigastric a. into six patterns, depending on whether the anastomosis was sited in the medial or lateral branch and the level at which the branches originated.  相似文献

Background  Vessels in the supraclavicular area and their contribution to skin vascularization have always been studied for flaps planning in head and neck reconstruction and many pedicled flaps have been described based on those vessels. Little has been written instead about the vascularization of the supraclavicular skin itself for the use as a free flap. The purpose of this anatomical study was to assess the vascularization of the supraclavicular skin and the possibility of finding an adequate pedicle to harvest it as a free flap in order to close the donor site directly. Methods  A total of 25 cadavers, 10 formalin fixed and 15 fresh, have been studied in cooperation with the Division for Clinical–Functional Anatomy, Department of Anatomy, Histology and Embryology, Innsbruck Medical University, Innsbruck, Austria and the Laboratoire d’Anatomie, Universiteé R. Descartes, Paris, France. Results  The supraclavicular skin was nourished by perforators coming from the transverse cervical artery and constantly present in an average number of four. Venous drainage was accomplished through the superficial cervical vein, and not through the venae comitantes of the transverse cervical artery. Conclusions  Based on the results of this investigation, a free supraclavicular transverse cervical artery perforator (STCAP) flap seems to be feasible pedicled on perforators from the transverse cervical artery and drained by the superficial cervical vein. Due to its thickness and skin texture, it can be indicated for facial and intraoral defects, with the limitations of a relatively short pedicle. Primary closure of the donor site can be accomplished concealing the scar in the neck crease.  相似文献
