During the last decade, the use of primary amputation has decreased, and a larger number of patients are being treated with resection and reconstruction with limb preservation. The advantage of chemotherapy, improvements in diagnostic imaging methods and newer techniques for reconstruction have made limb salvage an alternative to amputation for most patients with malignant bone tumor. Clinical results and functional results of the limb salvage operation of bone tumors treated at the Department of Orthopaedic Surgery, Guro Hospital, Korea university was reviewed. Eighteen bone tumors(seven giant cell tumors and eleven malignant bone tumors.) were studied over a period of five years. The limb salvage group included fourteen endoprothesis, two pasteurized autograft, one near total scapulectomy and one rotationplasty. Functional evaluation was performed according to the Enneking's modified system. The results were as followed; 1. At a mean follow-up of thirty two months (15-77 months), fourteen(83%) of the eighteen patients with limb salvage procedures had been continuously disease free. 2. There are no local recurrence but deep infection developed in two patients and three patients with distant metastasis. 3. Thirteen(87%) of the fifteen patients showed above 60% of functional results. 4. Fourteen(93%) of the fifteen patients were satisfied with the limb salvage procedures.

Recently limb-salvage operation is widely used for the treatment of malignant bone tumor. But distal leg is out of range of limb-salvage operation due to its technical problem. We report satisfactory limb-salvage operation with tumor prosthesis in 3 cases of osteosarcoma of the distal tibia and fibula. Two cases involved in the tibia and 1 case in the fibula. Average age at operation was 23 years. Neoadjuvant and adjuvant chemotherapy were performed in all 3 cases. We used custom made tumor prosthesis which is designed by Seoul National University Orthopaedic Department. Overall Functional Evaluations by Enneking rating system were good in all 3 cases. All cases are CDF(continuosly disease free since the surgical procedure) state at mean follow-up 2 year and 9 months. In conclusion limb-salvage with tumor prosthesis is useful treatment modality for malignant bone tumor of distal tibia and fibula. Good functional results and few complications suggests limb salvage of distal lower leg may be replaceable with B-K amputation.

We retrospectively evaluated our results of replantations of distal digital amputations and analyzed the factors deterrent to the survival of replanted digits. From January 2004 to 2005 June, we performed 101 cases of replantations following complete amputations at or distal to interphalangeal joint level. The study included 98 patients with a mean age of 35.6 years (range 1 to 63 years). Amputation level correlated to zone I (distal to the lunula)in 47 cases and zone II (lunula to distal interphalangeal joint) in 54 cases according to Yamano's classification. According to the mechanism of amputation, 24 cases (22.9%) suffered from guillotine type injury, 27 cases (27.1 %) from avulsion type injury and 50 cases (50%) from crush type injury. In all cases, a single arterial anastomosis was performed. Venous anastomosis on either volar or dorsal side was performed in 12 cases of amputation in zone II. Salvage procedure for venous drainage was performed in 98 cases. The mean duration of salvage procedures was 5.9 days (ranging from 4 to 14 days). Successful replantation was achieved in 96 cases (95.1%), which included 93.7% cases in zone I amputations and 96.3% cases in zone II amputations. A single venous anastomosis was performed in 12 cases of amputation in zone II. All of them survived completely. Among the 5 cases that failed to survive, 3 cases were related with avulsion injury in zone I. Initial mechanism of injury determines the survival rate of amputated parts as it is directly related with the status of vessels and soft tissues. Meticulous precaution during the salvage procedure may affect the overall survival rate of distal digital replantations.

Background: The major limitation of arteriovenous graft access is the high incidence of thrombotic occlusion. This study investigated the outcomes of our salvage strategy for thrombosed hemodialysis arteriovenous grafts (including surgical thrombectomy with balloon angioplasty) and evaluated the efficacy of intragraft curettage. Methods: Salvage operations were performed for 290 thrombotic occluded arteriovenous grafts with clinical stenotic lesions from 2010 to 2018. Of these, 117 grafts received surgical thrombectomy and balloon angioplasty from 2010 to 2012 (group A), and 173 grafts received surgical thrombectomy and balloon angioplasty, with an additional salvage procedure using a curette and a graft thrombectomy catheter, from 2013 to 2018 (group B). Outcomes were described in terms of post-intervention primary patency and secondary patency rates. Results: The post-intervention primary patency rates in groups A and B were 44.2% and 66.1% at 6 months and 23.0% and 38.3% at 12 months, respectively (p=0.003). The post-intervention secondary patency rates were 87.6% and 92.6% at 6 months and 79.7% and 85.0% at 12 months, respectively (p=0.623). Multivariate Cox regression analysis demonstrated that intragraft curettage was a positive predictor of post-intervention primary patency (hazard ratio, 0.700; 95% confidence interval, 0.519-0.943; p=0.019). Conclusion: Surgical thrombectomy and balloon angioplasty showed acceptable outcomes concerning post-intervention primary and secondary patency rates. Additionally, intragraft curettage may offer better patency to salvage thrombotic occluded arteriovenous grafts with intragraft stenosis.

It has been known that the vessels of the finger tip are very small and have many branches, so the anastomosis of this vessel is very difficult. But when this operation achieves success, the replanted finger tip provides adequate soft tissue, restoration of the length, sensory and nail. The authors describe the result of finger tip replantation in 94 patients, 103 finger tips, from October 1999 to June 2002. We performed the salvage procedure in all cases. The success rate of finger tip replantation was 74.8%. We achieved higher success rate, when we succeeded anastomosis of the central artery. The function of the replanted fingers was good. The average TAM was 80% and patient satisfaction was high. We be live that we can achieve higher success rate by anastomosing central artery and performing delicate salvage procedure.

Background The prosthetic dura is an essential element in the protection of the cranial parenchyma and prevention of cerebrospinal fluid leakage. Although prosthetic dura are widely used in neurosurgery, they occasionally provoke infection, which can be a major concern after neurosurgical treatment. However, removal of the prosthetic dura carries a risk of brain parenchyma injury and cerebrospinal fluid leakage. The salvage of infected prosthetic dural material has not been adequately addressed in the literature. In this study, we demonstrate the value of the combination of a meticulous surgical debridement of necrotic tissue and simultaneous muscle free flap for intractable postoperative epidural abscess without removal of the infected prosthetic dura. Methods Between 2010 and 2012, we reviewed the data of 11 patients with persistent infection on the prosthetic dura. The epidural infections each occurred after a neurosurgical procedure, and there was soft tissue necrosis with the disclosure of the underlying prosthetic dura and dead bone around the scalp wound. To salvage the infected prosthetic dura, meticulous debridement and a muscle free flap were performed. Results All 11 patients experienced complete recovery from the complicated wound problem without the need for further surgical intervention. No signs of prosthetic dural infection were observed during the mean follow-up period of 11 months. Conclusions The combination of a meticulous surgical debridement and coverage with a muscle free flap is an effective treatment for salvage of infected prosthetic dura.

Pharmacological ablation of the ciliary body by intravitreal injection of a cytotoxic dose of gentamicin was utilized for the treatment of absolute glaucoma in 13 dogs. Complications of this procedure were hyphema(2), corneal opacity(2), iris bombe(1), cataract(1) and chronic inflammation(1). Injection time was one time in 10 dogs, two times in 2 dogs and 3 times in a dog. Intravitreal injection of gentamicin was thought as a economic salvage procedure and has resulted in successful lowering of intraocular pressure.

Although the success rate of deep inferior epigastric perforator (DIEP) flaps has increased, late flap failures still occur and have a low salvage rate. The present article describes a case of salvage of a case of late flap failure using the pedicle vein as a vein graft source. A 50-yearold woman underwent a bilateral DIEP free flap procedure. On postoperative day 6, she experienced flap compromise and underwent emergency flap revision. In the flap revision, flap venous drainage and the superficial inferior epigastric vein were completely obstructed. A Fogarty catheter was used to remove a thrombus from the completely obstructed pedicle vein, and this pedicle vein was used as a graft source and was ligated in retrograde fashion to the flap vein stump. After injection of urokinase into the arterial branch, venous flow to the flap was restored. At a 6-month follow-up visit in the outpatient clinic, only partial fat necrosis at the flap was noted. By dissecting various perforators in the initial operation, decisions regarding immediate revision can be made with more confidence. Additionally, the combined procedures performed in this case may be helpful even for practitioners treating cases of late flap compromise.
