1/21. Balloon compression of the intramaxillary sinus for intractable post-traumatic bleeding from the maxillary artery. Case report.We present a case of severe intractable epistaxis after midfacial trauma in which the bleeding was identified as coming from the descending palatine artery, a branch of the maxillary artery. It could not be controlled by simple packing, and was stopped by inserting a balloon into the maxillary sinus, tamponading the injured vessel in the sphenopalatine fossa (pterigopalatine fossa). We describe an easy and practical emergency manoeuvre to control bleeding from inaccessible branches of the maxillary artery and to prevent rebleeding after embolisation.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/21. Usefulness and limitations of artificial dermis implantation for posttraumatic deformity.We have previously reported the use of artificial dermis implantation to cover exposed major vessels and to correct a depressed region after tissue resection and bone deformity with satisfactory results. In this paper, we present cases with depressed lesions and adhesive lesions after trauma, treated with artificial dermis implantation. Artificial dermis (Terudermis, Terumo Co. Ltd., tokyo, japan) was implanted in 12 cases of posttraumatic deformity. Eight of the 12 cases involved a depressed lesion, and the other four involved adhesive lesions. There was no postoperative infection or allergic reaction in any of the patients. Improvement of the deformity was obtained in all cases, but the degree of volume reduction in traumatic cases is likely to be more severe than that in the non-traumatic cases previously reported. In conclusion, artificial dermis implantation is an easy, safe, and useful method to correct a posttraumatic deformity, such as a depression or an adhesion, although it is important to note that depressions require overcorrection in order to obtain satisfactory results, as compared with non-traumatic cases treated with artificial dermis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/21. First successful replantation of face and scalp with single-artery repair: model for face and scalp transplantation.Successful replantation of the scalp with microanastomosis of a single artery and vein has been reported to produce reliable results. In fact, there have been several reports of scalp replantations based on one-artery and vein repair. There has been a face and scalp replantation reported in the literature, but this was as two separate parts and was based on several arterial and venous repairs. The authors performed the first successful replantation of a face and scalp with repair of a single artery and, of course, two veins. A 21-year-old man presented after his face and scalp were completely severed. The patient's long hair was caught in a conveyor belt at work. The face and scalp underwent replantation, with repair of the right superficial temporal artery with an interposition vein graft. A multiteam approach allowed for minimization of overall ischemic time and simultaneous preparation of the vessels on the patient and amputated part as well as vein graft harvest from the arm. Also critical to the success of the procedure, the small portions of the vessels of the amputated part were sent for frozen section to differentiate artery from vein. Initially, only the right superficial temporal vein was repaired. One week after replantation, the patient returned for treatment of venous congestion of an area to the opposite side of the forehead partial transection, with repair of the left superficial temporal vein, also. This saved the entire part that underwent replantation, and the entire part survived. The face and scalp can undergo replantation based on single-artery repair.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
4/21. Prefabricated galeal flap based on superficial temporal and posterior auricular vessels.scalp layers are widely used in reconstructive procedures. The authors used prefabricated galeal flaps based on the superficial temporal or postauricular vessels for ear, cheek, mandible, and cranium reconstructions in three cases. In case 1, synchronous beard and ear reconstructions were accomplished by using the temporoparietal and retroauricular flaps. In case 2, a buccomandibular defect was reconstructed by transposing the supra-auricular and retroauricular galea with prefabricated bone and skin. In case 3, an epidural hematoma in the left frontoparietal area was evacuated after a circular craniectomy. The harvested bone was not put back on the defect area but buried between the periosteal and galeal layers because of brain edema. These layers were raised as an osteogaleoperiosteal flap and transposed onto the defect area after 7 weeks. When used with a prefabrication method, scalp layers offer versatile options for repairing composite defects of the head region. A galeal flap based on the posterior auricular vessels is practical and reliable in reconstructive procedures. The authors suggest that this flap is an option in cases in which the temporoparietal fascia artery or the superficial temporal artery is not available. Prefabrication of the harvested cranial bone inside the adjacent tissues offers several advantages in that a viable bone is provided at the end of the procedure, intervention at a distant area is avoided, the graft is placed on osteogenic tissue (periosteum) that is also transposed onto the defect, and sophisticated procedures such as microsurgical techniques are not needed.- - - - - - - - - - ranking = 6keywords = vessel (Clic here for more details about this article) |
5/21. Loss of facial identification of the survivor after firearm injury to the head.Firearm wounds to the head are often fatal and are routinely encountered in the practice of forensic medicine. Herein we presented a patient who was wounded with a military rifle. This condition is unique and interesting for forensic medicine because none of the vital structures or major vessels were injured although the patient had a firearm injury to his head. In contrast to many other cases, the vital signs of our patient were normal and he was conscious on admission. Although the patient was considered lucky because he was still alive, he now had an unrecognizable face.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/21. An ideal and versatile material for soft-tissue coverage: experiences with most modifications of the anterolateral thigh flap.Free anterolateral thigh flaps are a popular flap used for the reconstruction of various soft-tissue defects. From April, 2002 to June, 2003, 32 free anterolateral thigh flaps were used to reconstruct soft-tissue defects. Twenty-three of these flaps were used for lower extremity reconstruction, and nine were used for head and neck reconstruction. There were 24 male and eight female patients, with ages between nine and 82 years. The size of the flaps ranged from 11 to 32 cm in length and 6 to 18 cm in width. Five flaps required reoperation for vascular compromise in four patients and for twisting of the pedicle in another patient. While four of these were salvaged, one flap was lost due to recipient vessel problems. Musculocutaneous perforators were found in 23 cases, and septocutaneous perforators were found in nine cases. In four cases, thinning of the flap was performed. The flap was used as a flow-through type for lower extremity reconstruction in three patients. In two patients, the flap was used as a neurosensory type for foot reconstruction. Eighteen cases underwent split-thickness skin grafting of the donor site and, in the remaining cases, the donor sites were closed primarily. In three patients, the donor areas required a partial skin regrafting procedure. No infections or hematomas were observed. Despite some variations in its vascular anatomy, the anterolateral thigh flap offers the following advantages: 1) it has a long and large-caliber vascular pedicle; 2) it has a wide, reliable skin paddle; 3) it may be harvested as a neurosensory flap; 4) it can be harvested whether its pedicle is septocutaneous or musculocutaneous; 5) it can be designed as a flow-through flap; 6) it can be elevated as a thin or musculocutaneous flap; and 7) the procedure can be performed by two teams working simultaneously, and no positional changes are required.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/21. Clinical applications of free soleus and peroneal perforator flaps.Clinical applications of two free lateral leg perforator flaps are described: a free soleus perforator flap that is based on the musculocutaneous perforator vessels from one of the three main arteries in the proximal lateral lower leg, and a free peroneal perforator flap that is based on the septocutaneous or direct skin perforator vessels from the peroneal artery in the distal and middle thirds of the lateral lower leg. The authors applied free soleus perforator flaps to 18 patients and free peroneal perforator flaps to five patients with soft-tissue defects. The recipient site was the great toe in 14 patients, the hand and fingers in five patients, the leg in two patients, and the upper arm and the jaw in one patient each. The largest soleus perforator flap was 15 x 9 cm, and the largest peroneal perforator flap was 9 x 4 cm. Vascular pedicle lengths ranged from 6.5 to 10 cm in soleus perforator flaps and from 4 to 6 cm in peroneal perforator flaps. All flaps, except for the flap in one patient in the peroneal perforator flap series, survived completely. Advantages of these flaps are that there is no need to sacrifice any main artery in the lower leg, and there is minimal morbidity at the donor site. For patients with a small to medium soft-tissue defect, these free perforator flaps are useful.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
8/21. The free serratus anterior flap and its cutaneous component for reconstruction of the face: a series of 27 cases.BACKGROUND: The serratus anterior flap is commonly used without its cutaneous component and is covered with a skin graft. The authors have successfully used the free serratus anterior flap along with its skin paddle and have found it to be valuable for reconstruction of the face. methods: Fresh cadaveric dissections and arteriography were performed to identify perforator vessels to the skin overlying the muscle. Clinically, free transfer of the musculocutaneous flap to the face was carried out in 27 patients, mostly for severe noma (infection) sequelae. RESULTS: Anatomical dissection and arteriography revealed no cutaneous perforator vessels directly communicating with the vascular pedicle of the muscle. However, large perforators from the intercostal vessels were found passing through the muscle to reach the skin. In the clinical cases, flap survival was 100 percent in 24 patients. CONCLUSIONS: The serratus anterior musculocutaneous flap is reliable and particularly well-suited for reconstruction of the face, and has many advantages. The authors speculate that the skin paddle may be vascularized by perforators from the intercostal vessels communicating with the thoracodorsal pedicle through intramuscular choke vessels.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
9/21. Haemostasis by angiographic embolisation in exsanguinating haemorrhage from facial arteries. A report of 2 cases.life-threatening exsanguinating haemorrhage from arteries of the face following trauma is uncommon. When it occurs it is often located in the relatively inaccessible parts of the vessels and requires deep face or neck exploration and ligation of the main feeding vessel. The procedure requires expert head and neck vascular surgery performed under general anaesthesia, which is often not suitable in these haemodynamically unstable patients. In addition, surgery is often rendered more difficult by the associated post-traumatic swelling and disfigurement. Because of these considerations, angiographic embolisation of the bleeding vessels was performed as an alternative to surgical exploration. This report illustrates its use in achieving haemostasis in 2 patients.- - - - - - - - - - ranking = 3keywords = vessel (Clic here for more details about this article) |
10/21. The versatile temporoparietal fascial flap: adaptability to a variety of composite defects.The unique properties of the temporoparietal fascial flap (TPFF) offer adaptability in reconstruction of a variety of composite defects. The broad, thin sheet of vascularized tissue may be transferred alone or as a carrier of subjacent bone or overlying skin and scalp. As a pedicled flap, it is ideal for defects of the orbital, malar, mandibular, and mastoid regions. As a free-tissue transfer, the large vessels and lack of bulk find broad utility in reconstruction of the extremities. This flap is our choice for reconstruction of the dorsal hand and non-weight-bearing surfaces of the foot. A viscous gliding surface decreases friction for tendon excursion. The thin contour is aesthetically superior to thicker flaps, allowing unmodified footwear or gloves. The pliable fascia convolutes into surface defects (e.g., bone craters) or drapes over skeletal frameworks (e.g., ear cartilage). The rich capillary network offers nutrition to saucerized bone, cartilage or tendon grafts, and overlying skin grafts. The geometry of the skull lends to fabrication of membranous bone for complex facial puzzles. The donor site is well disguised by hair growth. Twelve cases performed over a 2-year period demonstrate the versatility of this flap. These include complex foot reconstruction, ear and scalp avulsion, shotgun wound of the cheek and orbit, posttraumatic jaw recontouring, chronic osteomyelitis of the hand and foot, and acute resurfacing of dorsal hand with tendon reconstruction.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
