Stent-Graft Placement for Radiation-Induced Abdominal Aortic Stenosis after Renal Autotransplantation.

Renovascular hypertension (RVH) is a common cause of secondary hypertension. However, there have been no reports on RVH due to radiation-induced abdominal aorta stenosis after renal autotransplantation. A 27-year-old woman with a history of neuroblastoma treated by radiation therapy and RVH treated with renal autotransplantation presented with hypertension and dyspnea. At age 19, she had experienced hypertensive heart failure due to RVH from radiation-induced left renal artery stenosis and had undergone renal autotransplantation involving the extraction of her left kidney. Her systolic blood pressure (BP) was well-controlled but had increased progressively. She was diagnosed with hypertensive heart failure and admitted to hospital. Although her dyspnea soon subsided after treatment, her BP remained high. Renal artery ultrasound revealed no obvious stenosis. The ankle brachial pressure index (ABI) showed a significant bilateral decrease to 0.71/0.71 (right/left) from 0.94/0.95 eight years before. Magnetic resonance angiography and aortic angiography revealed severe stenosis in the abdominal aorta, and the systolic pressure gradient of intra-aortic blood flow, distal and proximal to a stenotic lesion, was 58 mmHg. These arterial stenoses in the irradiated area were highly suggestive of radiation-induced vasculopathy. She finally underwent an endovascular VIABAHN VBX balloon-expandable stent-graft placement for this radiation-induced abdominal aorta stenosis, which resolved the pressure gradient. After the procedure, her ABI improved to 0.91/0.88 and her BP was well-controlled. This is the first case of successful stent-graft placement for RVH after renal autotransplantation due to radiation-induced abdominal aorta stenosis as a consequence of neuroblastoma.

Postoperative Infection After Anterior Cruciate Ligament Reconstruction: Prevention and Management.

Because septic arthritis after anterior cruciate ligament reconstruction is an uncommon complication, information on prevention strategies has not been extensively studied. Recommendations that can be made from the available evidence are as follows: (1) prophylactic intravenous antibiotics should be given preoperatively; (2) patellar tendon autograft use decreases the possibility of a postoperative infection; and (3) vancomycin presoaking of grafts is strongly recommended, especially when performing hamstring autograft anterior cruciate ligament reconstruction. When septic arthritis presents after anterior cruciate ligament reconstruction, early management is crucial to allow a satisfactory outcome. Accordingly, early clinical suspicion is the most important factor to achieve a timely diagnosis. The treatment of choice is arthroscopic lavage with intravenous antibiotic treatment. Graft retention, when possible, is important for obtaining better functional results.

MATERIALS AND METHODS: This update includes the potential benefits and risks of using fat transfer techniques on the body. RESULTS: The current literature and author experiences are provided to help understand this growing field of aesthetic procedures. CONCLUSIONS: The use of nonfacial fat transplantation is increasing and will become a larger part of aesthetic practices.

Parathyroid carcinoma arising from auto-transplanted parathyroid tissue after Total Parathyroidectomy in chronic kidney disease patient: a case report.

BACKGROUND: Secondary hyperparathyroidism is a common complication in patients with chronic kidney disease that requires vigilant treatment due to its high mortality rate. Pharmacologic therapy is recommended as an initial treatment; if there is no response, a total parathyroidectomy is performed. In some cases, surgery is accompanied by auto-transplantation of parathyroid tissue. CASE PRESENTATION: The patient was diagnosed with chronic kidney disease and received a kidney transplant. However, due to rejection of the transplanted kidney, medical nephrectomy was carried out and routine hemodialysis was initiated and observed. At this time, secondary hyperparathyroidism with elevated parathyroid hormone and hyperphosphatemia developed and pharmacologic treatment was applied. However, there was no response to pharmacologic treatment; therefore, total parathyroidectomy with auto-transplantation was performed. Eight years after surgery, a growing mass was observed in the transplantation site, accompanied by an elevation of parathyroid hormone. A complete resection of the mass was performed, and the patient was diagnosed with parathyroid carcinoma. Additional adjuvant radiation therapy was ordered, and the patient is being monitored. CONCLUSIONS: This is a rare but remarkable case of parathyroid carcinoma arising from auto-transplanted parathyroid tissue after total parathyroidectomy in a patient with secondary hyperparathyroidism. We suggest caution should be taken when choosing to auto- transplant parathyroid tissue and that careful postoperative observation should be performed.

Macro Fat Embolism After Gluteal Augmentation With Fat: First Survival Case Report.

Gluteal augmentation with fat has become one of the most common cosmetic procedures worldwide. Gluteal augmentation is designed to increase the volume and contour of the gluteal region. Intramuscular lipoinjection has been linked to multiple reports of severe complications, including death due to macro fat embolism (MAFE). The authors present the first reported case of survival and successful recovery after MAFE secondary to gluteal augmentation with fat. A 41-year-old woman, ASA II, was scheduled for augmentation mammaplasty, liposuction, and gluteal augmentation with fat. The patient was operated under general anesthesia with a total intravenous anesthesia technique. A total of 3.5 liters of fat was liposuctioned with no complications. The patient was then positioned in a lateral decubitus position for gluteal augmentation with fat. Right after the last injection, the anesthesiologist noticed a sudden change in capnography followed by hypotension, bradycardia, and hypoxemia. The first reaction in the operating room was to consider that the patient was experiencing a severe episode of fat embolism. She was then resuscitated and transferred to a tertiary facility for intensive care management. To our knowledge, this is the first case report of successful resuscitation in a patient experiencing severe MAFE after gluteal augmentation with fat. We believe that this patient survived the event due to early detection, aggressive management, and proper transfer to an intensive care unit. Level of Evidence: 5.

Reconstruction of iliac crest defect after autogenous harvest with bone cement and screws reduces donor site pain.

BACKGROUND: The iliac crest is the most common autogenous bone graft donor site, although associated with postoperative pain, functional disability, cosmesis, morphology and surgical satisfaction. We assessed each aspect above by comparing iliac crest reconstruction with bone cement and screws following harvest with no reconstruction. METHODS: We evaluated patients who underwent large iliac crest harvesting, including ten patients who underwent iliac crest defect reconstruction with bone cement and cancellous screws (R group) and ten randomly matched patients without reconstruction (NR group) were evaluated prospectively in the same period. Local pain, cosmesis and other complications were assessed postoperatively at 1 week, 6 weeks, 3 months and 6 months. RESULTS: Pain, cosmesis and satisfaction of patients significantly differed between the two groups. The R group exhibited less complications and lower pain visual analogue scores at postoperative 1 week (p < 0.001), 6 weeks (p < 0.001) and 3 months (p < 0.01) but not at 6 months, at which time patients reported almost no pain. One patient reported pain for more than 1 year in the NR group. The R group exhibited better cosmesis, morphology and satisfaction than the NR group. In the NR group, one patient suffered pain when sitting up and another when wearing a belt. CONCLUSION: Postoperative pain can be reduced and cosmesis can be improved through reconstructing the iliac crest defects after autogenous harvesting with bone cement and cancellous screws. The technique is simple, safe and easy to implement.

Anatomical Study of Temporal Fat Compartments and its Clinical Application for Temporal Fat Grafting.

BACKGROUND: Low satisfaction rates and severe complications are two major limitations for temporal hollowing augmentation using autologous fat grafting. Despite fat compartments in temporal region have been reported, its clinical applied anatomy for fat grafting have not been the subject of studies that show its benefits objectively and statistically. OBJECTIVES: To investigate temporal fat compartments and relative neurovascular structures in cadavers, developing a safe and effective fat grafting technique for temporal hollowing augmentation. METHODS: The study was conducted on 8 cadavers (16 temples). The tissue layers, fat compartments, ligaments, and neurovascular structures in the temporal region were analysed. The variables were the number and location of sentinel veins, perforator vessels of the middle temporal vein. Measurements were taken with a digital calliper. RESULTS: Two separate fat compartments, the lateral temporal-cheek fat compartment and lateral orbital fat compartment, were found in the subcutaneous layer, and two separate septum compartments, the upper and lower temporal compartment, were found in the loose areolar tissue layer. One sentinel vein and 1 to 6 perforator vessels were found to travel through the subcutaneous tissue layer, traverse the overlapping tissue layers in the lower temporal septum region, and finally join in the middle temporal vein. CONCLUSIONS: The four fat compartments in the temporal region are ideal receipt sites for fat grafting. The medial border of the junction of the hairline and temporal line is a safe and effective cannula entry site for temporal fat grafting. The anterior half of the lower temporal compartment is a "zone of caution" for temporal fat grafting.

Beta-tricalcium phosphate for orthopedic reconstructions as an alternative to autogenous bone graft.

Autogenous bone graft (autograft) remains the gold standard in the treatment of many orthopedic problems. However, graft harvest can lead to perioperative morbidity and increased cost. We tested the hypothesis that an osteoconductive matrix, beta-tricalcium phosphate (ß-TCP), would be a safe and effective alternative to autograft alone. Beta-tricalcium phosphate (ß-TCP) is considered as one of the most promising biomaterials for bone reconstruction. This study analyzes the outcomes of patients who received ß-TCP as bone substitutes in orthopedic surgery. METHODS: A total of 50 patients were enrolled in a controlled, non-inferiority clinical trial to compare the safety and efficacy of ß-TCP (25 patients) with those of autograft (25 patients) in indications requiring usually autograft. These 50 patients were categorized according to the etiology and morphology of the 54 bone defects resulting from elective surgical procedures, such as 34 open-wedge high tibial osteotomies, and 20 osteonecrosis treatments with core decompression. Radiographic (healing process with or without integration of ß-TCP), clinical (no other surgical procedure), functional outcomes and safety (with or without complications) were assessed through fifty-two weeks postoperatively. RESULTS: With regard to the primary endpoint (radiographic evolution), the fusion rate of the 34 open-wedge osteotomies was 100% (17 among 17) for patients in the group with ß-TCP compared with 94% (16 among 17) for patients in the autograft group. For the 20 cavitary defects (osteonecrosis), the radiographic union rates, as determined by the presence of osseous bridging, were 100% for patients in the group with ß-TCP and 100% for those in the autograft group. Clinically at one year, all quality-of-life and functional outcome data supported non-inferiority of ß-TCP compared with autograft, and patients in the ß-TCP group were found to have less pain and an improved safety profile. CONCLUSIONS: Treatment with ß-TCP resulted in comparable fusion rates, less pain and fewer side effects as compared with treatment with autograft. This study established clinical parameters where the ß-TCP alone can successfully support the osteogenic process.

Quadruple Valve Reoperation after the Ross Procedure.

Reoperations after the Ross procedure are rare, with autograft as well as homograft failure being the dominant causes for redo cardiac procedures. Due to increasing experience with valve-sparing aortic valve procedures, more valves can be preserved during redo surgery. Herein are reported the details of a patient who underwent quadruple valve reoperation comprising redo with a reconstructive approach after the short-term failure of pulmonary autograft and homograft with concomitant mitral and tricuspid regurgitation.

The impact of sensory deficits after harvesting hamstrings autograft for ACL reconstruction.

PURPOSE: The aim of this study was threefold: to investigate the incidence of sensory deficits after harvesting hamstrings autografts, to localise and measure the area of altered sensibility and to investigate the impact of any sensory deficit on the patients daily life. METHODS: A consecutive series of sixty-one patients were examined for sensory deficits related to harvest of hamstrings tendons 10 years after having had an anterior cruciate ligament reconstruction. A neurological examination of the leg was performed to investigate for potential altered sensibility and to quantify the extent of the lesion. The patients answered the anterior knee symptoms (AKS) questionnaire and additional questions regarding impact on activities of daily life by any sensory deficit. RESULTS: Eighty-five per cent of the examined patients had sensory deficits--experienced as numbness (78 %) and paraesthesia (16 %)--distal to the site of tendon harvesting. The mean affected area was 70 (SD 62) cm(2). No patients experienced sensory deficit symptoms to such a degree that it affected their activities of daily life, but the group with sensory deficit had significantly more AKS than patients without sensory deficit, as evaluated by the AKS score (P = 0.02). The most commonly reported complaints were related to strenuous activities and kneeling knee position. CONCLUSIONS: This long-term evaluation shows that sensory deficit after hamstring tendons harvesting affects a majority of patients and is probably permanent. Most patients reported this as being only mildly bothersome, but they have significantly more AKS as assessed by the AKS questionnaire. In clinical practice, patients should be counselled prior to tendon harvesting on the incidence and characteristic of the sensory deficit along with other possible peri- and postoperative complications. LEVEL OF EVIDENCE: Case series, Level IV.

Endovascular repair of a para-anastomotic pseudoaneurysm after renal autotransplantation: an alternative to open reconstruction.

Renal artery anastomotic pseudoaneurysms are rare after renal transplantation. The etiology tends to be technical, infectious, or degenerative, and repair is difficult with a high postsurgical complication rate. We report the first case of a complex autotransplant renal artery pseudoaneurysm repaired with kissing covered stents. A 52-year-old woman presented with severe left lower quadrant abdominal pain 6 years after a renal autotransplant for ureteral stenosis and recurrent pyelonephritis. A computed tomographic angiography (CTA) scan revealed a bilobed aneurysm arising at the anastomosis between the renal and common iliac arteries. Kissing covered stents were placed within the common iliac artery proximally and extending into the transplant renal artery and external iliac artery. Postdeployment angiography confirmed complete exclusion of the pseudoaneurysm and excellent flow into the transplant kidney and left lower extremity. A follow-up CTA scan at 1 month revealed continued stent-graft patency and complete exclusion of the pseudoaneurysm. An endovascular approach to transplant anastomotic pseduoaneurysms using kissing covered stents is a viable option to exclude aneurysmal changes and preserve flow to the transplanted organ in carefully selected patients.

[Characterization and treatment of three cases with complications after frontalis suspension using autogenous fascia lata].

BACKGROUND: To report three cases of severe complications after frontalis suspension using autogenous fascia lata CASES: All three cases showed lagophthalmos and eyelash inversion after frontalis suspension using autogenous fascia lata. During surgery, we found that the tarsus was raised upwards and distorted by the fascia lata which had contracted and adhered to the surrounding tissue. We excised the adhesion of the fascia lata. In case 1, we transplanted the fat and perifascial areolar tissue under the cicatrized orbicularis. In cases 2 and 3, we flattened the distorted tarsus with nylon mattress sutures. In case 2, we added a frontalis suspension using Gore-Tex one year later. In case 3, we fixed Gore-Tex between the tarsus and the released fascia lata. CONCLUSIONS: Lagophthalmos and eyelash inversion due to contraction of the fascia lata may be complications of frontalis suspension using the fascia lata. Prolonged follow-up after the surgery is essential, and if such complications occur appropriate treatment is required.

Osteochondritis dissecans of the metacarpal head in a soldier treated with osteochondral autograft transplantation surgery: A case report.

RATIONALE: Osteochondral autograft transplantation surgery (OATS) was introduced as a treatment for hand osteochondritis dissecans (OCD), and successful results were reported. However, the cartilage height of the donor plug has not yet been established compared with that of other joints. We present a case using OATS for OCD of the 3rd metacarpal (MCP) head that occurred in a soldier and the findings of magnetic resonance imaging (MRI) images taken at 12 weeks after surgery. PATIENT CONCERNS: A 21-year-old male presented with a painful, swollen 3rd MCP joint in the right hand. He was a soldier and right-handed; in addition, he did not recall any traumatic events, nor had he taken any corticosteroid medications before. The patient was excluded from military training and underwent conservative treatment with medication and a brace in a military hospital for 3 months. DIAGNOSIS: The patient was diagnosed with OCD due to avascular necrosis of the 3rd MCP head of the right hand through X-ray and MRI. INTERVENTIONS: OATS was planned as a surgical treatment. Surgery uncovered a 10 × 10 mm2, isolated cartilage defect of the 3rd MCP head that had an irregular margin and a loose body. Using Arthrex OATS, a 10-mm diameter, 10-mm depth hole was made at the articular defect site, and an 11-mm diameter, 12-length plug was harvested from the left lateral femoral condyle. The donor plug was inserted into the prepared defect site with press-fit fixation. OUTCOMES: At the last follow-up, the height of the articular cartilage had subsided with union on MRI 12 weeks after the surgery. However, the patient was asymptomatic with a normal range of motion of the right hand, and he returned to military training. LESSONS: Although the joints of the hand are small and non-weight bearing, the level of articular cartilage of the donor plug was subsided in a follow-up MRI in our case. We suggest that the difference in cartilage thickness between the donor and the recipient might have been the cause of subsidence of the articular cartilage, and therefore, it may be helpful to transplant donors with similar thicknesses of articular cartilage.

Quality of life after total pancreatectomy with islet autotransplantation for chronic pancreatitis in Japan.

BACKGROUND: Patients with chronic pancreatitis (CP) often have severe and intractable abdominal pain, leading to decreased quality of life (QOL), inability to work or attend school, and increased health care costs due to repeated emergency room visits and hospitalizations. METHODS: We evaluated the efficacy of total pancreatectomy and islet autotransplantation (TPIAT) in terms of pain control and QOL in CP patients treated at our center in Japan. To evaluate QOL, we used the Short-Form 36 Health Survey version 2 (SF-36v2® Standard, Japanese), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), and Quality of Life Questionnaire-Pancreatic Modification (QLQ-PAN28). RESULTS: Between August 2016 and June 2019, we performed this procedure in 5 patients. All patients were followed up for 12 months and all transplanted islets were still functioning at the 1-year follow-up. The major adverse events were abdominal wall hemorrhage, intestinal obstruction, intra-abdominal abscess, and abdominal pain requiring hospitalization; no case had sequelae. No major complications were due to islet transplantation. Pain scores improved postoperatively in all patients. Three QOL item dimensions role-physical (p = 0.03125), general health perception (p = 0.03125) and vitality (p = 0.03125) in the SF-36 were significantly improved 12 months after TPIAT. Mean values of many other QOL items improved, though not significantly. CONCLUSION: The QOL improvement after TPIAT for CP suggests its effectiveness in the Japanese population.

Safety and Effectiveness of Autologous Fat Grafting after Breast Radiotherapy: A Systematic Review and Meta-Analysis.

BACKGROUND: The purpose of this study was to evaluate the safety and effectiveness of autologous fat grafting after radiotherapy. METHODS: All studies published before December of 2019 were collected by searching on PubMed, Embase, Cochrane, Web of Science, China National Knowledge Infrastructure, and Wanfang Data. After independently screening the studies and extracting the data, Stata was applied to perform meta-analysis. RESULTS: Seventeen qualified articles were eventually included, involving a total of 1658 patients, of which 1555 underwent autologous fat grafting. Overall, empirically from the data, the use of autologous fat grafting after radiotherapy does not increase the incidence of complications or the risk of tumor recurrence. Through statistical analysis, the authors found that 152 patients suffered complications after undergoing autologous fat grafting [152 of 1555 (9.8 percent)]; 72 patients suffered complications after undergoing postradiotherapy autologous fat grafting [72 of 1040 (6.9 percent)], including seven cases of tumor recurrence [seven of 1040 (0.7 percent)]; and 80 patients suffered complications after undergoing autologous fat grafting without radiotherapy [80 of 515 (15.5 percent)], including seven cases of tumor recurrence [seven of 515 (1.4 percent)]. The authors also found that 970 of 1040 patients (93.3 percent) were satisfied with the results of postradiotherapy autologous fat grafting for breast reconstruction. CONCLUSIONS: This study has provided an evidence-based conclusion supporting the use of autologous fat grafting for breast reconstruction after radiotherapy. Autologous fat grafting can effectively correct breast deformity and contracture caused by breast-conserving therapy and radiotherapy and increase patient satisfaction without increasing the rate of tumor recurrence.

Decision-Making in Adult Cranial Vault Reconstruction.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Define and classify different types of cranial defects 2. Compare both autologous and alloplastic options for reconstruction 3. Develop an optimal approach for cranial vault reconstruction in various clinical scenarios. SUMMARY: Defects of the cranium result from various causes, including traumatic loss, neurosurgical intervention, skull tumors, and infection. Cranial vault reconstruction aims to restore both the structural integrity and surface morphology of the skull. To ensure a successful outcome, the choice of appropriate cranioplasty reconstruction will vary primarily based on the cause, location, and size of the defect. Other relevant factors that must be considered include adequacy of soft-tissue coverage, presence of infection, and previous or planned radiation therapy. This article presents an algorithm for the reconstruction of various cranial defects using both autologous and alloplastic techniques, with a comparison of their advantages and disadvantages.

Borderline tumour arising in a transposed ovary in utero: a rare complication of the Estes operation.

Ovarian transposition into the uterine cavity to restore fertility, the so-called Estes operation, has rarely been performed worldwide. Malignant degeneration of such transposed ovaries has never been reported in the literature. We present a case of a borderline tumour arising in a transposed ovary after an Estes operation.

Complications with Hair Transplantation.

Most complications associated with hair transplant surgery are usually preventable and most often arise as a consequence of poor planning or faulty surgical technique. Patients should be evaluated for having realistic goals and a pattern that is amenable to aesthetic restoration. A good treatment plan must consider the potential for future hair loss. Well-informed patients who carefully follow instructions and take an active role in the postoperative recovery process minimize the chance of patient-controlled complications. This article discusses potential complications associated with hair restoration surgery, and the roles of the patient and physician in decreasing the risk of complications.

Treatment of Chronic Patellar Tendon Rupture with Hamstrings Tendon Autograft.

We describe a new simple reconstruction for neglected chronic ruptures of patellar tendon using ipsilateral hamstrings tendon autograft. This has been validated in thirteen patients with mean follow up six years resulting in favorable outcome. Thirteen patients with mean age 58.2 years (range 30-64 years) presented with chronic patellar tendon rupture. They all underwent patellar tendon reconstruction using ipsilateral hamstrings tendon autograft. The average time from injury was 10 months (range 3-20 months). The cause of rupture was fall from height or after TKA and the preoperative Lysholm score was 65 (range 50-80). Postoperatively with a mean follow up of six years (range 5-7 years), all patients had a stable knee with mean flexion of 123°, extension lag 0°, and Insall-Salvati index 1.2. Quadriceps power was regained in 8 cases to 5/5 and in 5 cases to 4/5. No complications were inspected. The postoperative Lysholm score was 93 (range 89-95). Patellar tendon reconstruction using ipsilateral hamstrings as free autograft, consists an effective treatment option for chronic neglected patellar tendon ruptures. Our technique has favorable clinical outcome, complications are not expected, and consist a simple and anatomic reconstruction with a powerful graft, without the requirement for allograft or implants.
