Arterial supply to the sciatic nerve in the gluteal region

CLINICAL ANATOMY, Issue 1 2008
Effrossyni Georgakis
Abstract The arterial supply to the sciatic nerve was investigated in 20 human lower limbs (10 right, 10 left) from 20 cadavers (14 females, aged 84 ± 9.6 years, range 66,95 years: 6 males, aged 80 ± 8.2 years, range 70,90 years). In all limbs examined at least 1 sciatic artery could be identified supplying the sciatic nerve in the gluteal region. In total 28 sciatic arteries were identified, of which 14 arose from the medial circumflex femoral artery, 11 from the inferior gluteal artery, 2 from the first perforating artery, and 1 from the internal pudendal artery. In 5 limbs, 2 sciatic arteries were observed, being independent branches from the medial circumflex femoral and inferior gluteal arteries in 4 limbs and separate branches of the medial circumflex femoral artery in 1 limb. In 1 limb, 4 sciatic arteries were observed: 1 from the inferior gluteal artery, 2 from the medial circumflex femoral artery, and 1 from the first perforating artery. In the remaining 14 limbs a single sciatic artery was observed, which in one case arose from the internal pudendal artery, a previously unreported observation. Clin.

Persistent sciatic vessels associated with an arteriovenous malformation

JOURNAL OF ANATOMY, Issue 3 2001
ZELIHA KURTO
The sciatic artery is the major arterial supply to the lower limb bud at an early embryological stage. It primarily originates from the dorsal root of the umbilical artery. After the 22 mm embryological stage, the sciatic artery involutes and the femoral artery system develops as the major inflow source to the lower limb. In the adult, remnants of the sciatic artery persist as the proximal portion of the inferior gluteal artery, the popliteal and peroneal arteries (Williams et al. 1989). It is suggested that either failure in development of the femoral system or failure in regression of the sciatic artery results in persistence of this artery (Arey, 1965). We report a rare example of persistent sciatic artery (PSA) accompanied by arterio-arterial and arteriovenous anastomoses. [source]

Breast reconstruction using perforator flaps

JOURNAL OF SURGICAL ONCOLOGY, Issue 6 2006
Jay W. 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]

Ischial pressure sores: Reconstruction using the perforator-based reverse flow musculocutaneous 180° propeller flap

MICROSURGERY, Issue 8 2009
Rafael G. Jakubietz M.D.
The treatment of pressure sores requires soft tissue reconstruction with thick tissue to provide padding of bony prominences and obliterate dead space. Fasciocutaneous flaps may not provide adequate bulk. Propeller flaps (180°) based on perforators from the gluteal artery may be harvested as a reverse flow musculocutaneous flap including a muscle plug to reconstruct deep cavities. Three patients presenting with deep pressure sores required reconstruction of large cavities. In addition to a regular 180° propeller flap, a muscle plug based on a perforator found in the blade of the propeller was used to add bulk to the flap and obliterate the cavity with well-vascularized tissue. One flap required secondary closure of the donor site due to dehiscence, one hematoma required drainage. All flaps survived completely. No recurrence of osteomyelitis or pressure sores was seen. The 180° propeller flap can be harvested as a reverse flow musculocutaneous flap including a muscle plug in the distal blade. This adds volume which is required to adequately obliterate large cavities in cases of osteomyelitis. This new technique may be useful in other areas as well. © 2009 Wiley-Liss, Inc.
