Recipient Vessels (recipient + vessel)
Selected AbstractsThe distal superficial femoral arterial branch to the sartorius muscle as a recipient vessel for soft tissue defects around the knee: Anatomic study and clinical applicationsMICROSURGERY, Issue 6 2009Fernando A. Herrera M.D. Complex wounds surrounding the knee and proximal tibia pose a significant challenge for the reconstructive surgeon. Most of these defects can be managed using local or regional flaps alone. However, large defects with a wide zone of injury frequently require microvascular tissue transfers to aid in soft tissue coverage and closure of large cavities. We describe a unique recipient vessel for microvascular anastomosis for free flap reconstruction involving the knee and proximal tibia through anatomic and clinical studies. © 2009 Wiley-Liss, Inc.

[source] Reverse flow facial artery as recipient vessel for perforator flapsMICROSURGERY, Issue 6 2009D.D.S., Frank Hölzle M.D., Ph.D. In perforator flaps, anastomosis between flap and recipient vessels in the neck area is often difficult due to small vessel diameter and short pedicle. The aim of this study was to investigate whether the retrograde flow of the distal, paramandibular part of the facial artery would provide sufficient pressure and size to perfuse perforator flaps. Before and after occlusion of the contralateral facial artery, retrograde and anterograde arterial pressure was measured on both sides of the facial artery in 50 patients. The values were compared with the mean systemic arterial pressure. Diameters of facial arteries in the paramandibular region and perforator flap vessels were evaluated by morphometry. Arterial pressure in the distal facial artery with retrograde flow was 76% of the systemic arterial pressure. The latter equaled approximately the anterograde arterial pressure in the proximal end of the facial artery. Mean arterial pressure of the facial arteries decreased after proximal occlusion of the contralateral facial artery, which was not significant (P = 0.09). Mean diameter of the distal facial arteries in the mandibular region was 1.6 mm (range 1.3,2.2 mm; standard deviation 0.3 mm; n = 50), that of the perforator flap arteries 1.3 mm (0.9,2.6 mm; 0.4 mm; n = 20). Facial arteries, based on reverse flow, successfully supported all 20 perforator flaps. Retrograde pulsatile flow in the distal facial artery sustains perforator flaps even if the contralateral facial artery is occluded. Proximity of the distal facial arteries to the defect compensates for short pedicles. Matching diameters of the arteries are ideal for end-to-end anastomosis. © 2009 Wiley-Liss, Inc.

[source] Usefulness of vascular bundle interposition of the descending branch of the lateral circumflex femoral vessels for free flap reconstruction of the calvarial defect,MICROSURGERY, Issue 7 2008Kazufumi Sano M.D. Usefulness of the descending branch of the lateral circumflex femoral vessels as a vascular bundle interposition graft was introduced. Large calvarial defect with no recipient vessel for direct anastomosis was successfully covered with free flap nourished by the cervical vessels through the vascular bundle interposition graft of the descending branch of the lateral circumflex femoral artery and its venae comitantes. The vascular bundle interposition has remarkable advantages over the venous graft regarding its patency and durability, especially in the head and neck region in which grafted vessels is difficult to be set on the straight. The descending branch of the lateral circumflex femoral vessels can be harvested up to 20 cm, and its diameter is suitable for interposition between conventional free flaps and recipient vessels in the head and neck region. © 2008 Wiley-Liss, Inc.

Granzow MD Abstract Background Perforator flaps allow the transfer of the patient's own skin and fat in a reliable manner with minimal donor-site morbidity. The deep inferior epigastric artery (DIEP) and superficial inferior epigastric artery (SIEA) flaps transfer the same tissue from the abdomen to the chest for breast reconstruction as the TRAM flap without sacrificing the rectus muscle or fascia. Gluteal artery perforator (GAP) flaps allow transfer of tissue from the buttock, also with minimal donor-site morbidity. Indications Most women requiring tissue transfer to the chest for breast reconstruction or other reasons are candidates for perforator flaps. Absolute contraindications to perforator flap breast reconstruction include history of previous liposuction of the donor site or active smoking (within 1 month prior to surgery). Anatomy and Technique The DIEP flap is supplied by intramuscular perforators from the deep inferior epigastric artery and vein. The SIEA flap is based on the SIEA and vein, which arise from the common femoral artery and saphenous bulb. GAP flaps are based on perforators from either the superior or inferior gluteal artery. During flap harvest, these perforators are meticulously dissected free from the surrounding muscle which is spread in the direction of the muscle fibers and preserved intact. The pedicle is anastomosed to recipient vessels in the chest and the donor site is closed without the use of mesh or other materials. Conclusions Perforator flaps allow the safe and reliable transfer of abdominal tissue for breast reconstruction. J. Surg. Oncol. 2006;94:441,454. © 2006 Wiley-Liss, Inc. [source] Scrotal reconstruction with a free greater omental flap: A case reportMICROSURGERY, Issue 5 2010Darren Ng M.B.B.S., M.R.C.S. We report a case of Fournier's gangrene, where we used the greater omentum as a free flap for scrotal reconstruction and outline the advantages over previously described methods. The greater omentum was harvested using a standard open technique. The deep inferior epigastric vessels were passed through the inguinal canal into the scrotal area as recipient vessels. The detached greater omental flap was prefabricated into a three-dimensional sac prior to inset and microvascular anastomoses. The flap was then covered by skin graft. The reconstruction had shown good early results with complete survival of the flap, as well as good functional and esthetic outcome at six months. The greater omentum can therefore be used as a free flap for scrotal reconstruction. It allows easy prefabrication and flap inset. The deep inferior epigastric vessels are also suitable recipient vessels. © 2010 Wiley-Liss, Inc. Microsurgery 30:410,413, 2010. [source] Head and neck reconstruction using cephalic vein transposition in the vessel-depleted neckMICROSURGERY, Issue 8 2009M.B.B.S., Vasileios Vasilakis B.Sc. In microvascular reconstructive surgery the patency of the recipient vessels is the key to successful outcome. In head and neck surgery there is often a lack of adequate recipient vessels as a result of chemoradiation therapy and ablative surgery. To overcome this it is crucial to identify vessels of adequate length and diameter outside the field of injury. We report our experience with cephalic vein transposition for drainage of seven free flaps,six intestinal and one osteocutaneous,for head and neck reconstruction. In five cases the cephalic vein was used during the free flap transfer and in two cases in salvage re-exploration surgery. All flaps survived completely. The anatomical course and location of the cephalic vein allow good patency and straightforward harvesting. Its vascular properties are predictive of reduced incidence of complications such as flap congestion and failure. We suggest that the cephalic vein offers a high venous flow drainage system for large free flaps and advocate its use in free intestinal transfer in the vessel-depleted neck as well as in re-exploration surgery. © 2009 Wiley-Liss, Inc.

Hanasono M.D. Microvascular reconstruction of head and neck defects can be extremely challenging in patients with a history of prior neck dissection and/or irradiation. We reviewed of 261 head and neck free flaps performed between 2004 and 2007 at a tertiary cancer center. One hundred twenty-four (52%) free flaps were performed in patients with a history of prior neck dissection and/or irradiation. The ipsilateral external carotid artery or one of its branches was not available in 43 (19%) cases: 13 with no history of prior neck dissection or irradiation, and 30 with a history of prior neck dissection and/or irradiation (P = 0.03). The ipsilateral internal/external jugular veins (IJ/EJ) were not available in 37 (16%) cases: 11 with no history of prior neck dissection or irradiation, and 26 with a history of prior neck dissection and/or irradiation (P = 0.002). Strategies for dealing with lack of a recipient vessels included anastomosis to contralateral neck vessels, transverse cervical vessels, internal mammary vessels, the cephalic vein, and the pedicle of another free flap. We propose an algorithm for locating recipient vessels adequate for microvascular anastomosis should the ipsilateral external carotid arterial and/or the internal/external jugular venous systems not be available, such as in the setting of prior neck dissection or irradiation. © 2008 Wiley-Liss, Inc.

[source] Selection of recipient vessels in microsurgical free tissue reconstruction of head and neck defectsMICROSURGERY, Issue 7 2007Sukru Yazar M.D. The development of microsurgical techniques has facilitated proper management of extensive head and neck defects and deformities. Bone or soft tissue can be selected to permit reconstruction with functional and aesthetic results. However, for free tissue transfer to be successful, proper selection of receipient vessels is as essential as the many other factors that affect the final result. In this article selection strategies for recipient vessels for osteocutaneous free flaps, soft tissue free flaps, previously dissected and irradiated areas, recurrent and subsequent secondary reconstructions, simultaneous double free flap transfers in reconstruction of extensive composite head and neck defects, and the selection of recipient veins are reviewed in order to provide an algorithm for the selection of recipient vessels for head and neck reconstruction. © 2007 Wiley-Liss, Inc.

[source] Incidence and significance of microscopic pathological lesions found in pedicle and recipient vessels used in microsurgical breast reconstructionMICROSURGERY, Issue 1 2003H.H. El-Mrakby M.D. The purpose of this study was to assess the incidence of abnormal vascular histology and to determine whether or not this was correlated with the incidence of postoperative microvascular problems. The microvascular histology of both donor and recipient vessels was studied in 38 patients (40 flaps) undergoing breast reconstruction with free TRAM flaps. Preoperative risk factors were assessed and correlated with histological changes in vessels, and both were tested against anastomotic complications. Thrombosis of either the artery or the vein of the flap was seen in 6 cases (15%), and of these, two flaps failed completely and one suffered partial necrosis. The occlusion affected the arterial anastomosis in 3 patients, and the venous anastomosis in 2 patients, while both the artery and the vein were thrombosed in one case. Preoperative risk factors such as smoking, obesity, radiotherapy, and chemotherapy were not associated with a significantly higher incidence of thrombosis or with significant histological abnormalities in vessels (P value varied between 0.3,0.06). Microvascular histology showed variable degrees of pathological changes in six flaps (15%); nevertheless, in this group, only one flap suffered a venous thrombosis, which ended in total flap loss. Among those with one or more risk factors (24 patients), only 2 had some evidence of histological abnormality of the blood vessels used for the microvascular anastomosis (P = 0.2). © 2003 Wiley-Liss, Inc.
