Serial transcranial Doppler ultrasonography (TCD) studies were carried out in 61 patients, who had been operated due to supratentorial brain tumours. Among 61 cases have been 26 gliomas, 19 meningiomas and 16 metastases. The Mean Flow Velocity (MFV) exceeding 120 cm/s in Middle Cerebral Artery (MCA) and 90 cm/s in Anterior Cerebral Artery (ACA) has been admitted as pathognomonic for vasospasm. The vasospasm has been stated in 14 cases (23%)--10 gliomas and 4 meningiomas out of 61 patients. The vasospasm has been more intense in ACA on the operated (lesion) side than in MCA and on the non operated (opposite) side.

Metastasis of breast cancer to the colon is rare. We report a case of a 49-year-old female who presented with a stenotic tumor of the descending colon five years after treatment of breast cancer with mastectomy and pedicled transverse rectus abdominis musculocutaneous flap. Laparotomy showed a diffusely infiltrated tumor over the descending colon. Anterior resection with loop ileostomy was performed, and the pathology showed that the colonic wall and the mesentery were diffusely infiltrated with poorly differentiated adenocarcinoma, which stained strongly for cytokeratin 7. The histologic diagnosis is consistent with colonic metastasis from ductal carcinoma of breast origin. In a patient with a history of breast cancer, colonic metastasis from the breast primary cancer should be considered, especially if the colonic lesion is scirrhous in nature. The incision for laparotomy and the probable stoma site should be planned carefully in females after breast reconstructive surgery.

Clear cell adenocarcinoma of the female urethra is extremely rare. We herein describe the 33rd case of clear cell adenocarcinoma of the female urethra in Japan. A 54-year-old female who presented with pollakisuria was referred to our department. Transvaginal examination showed a walnut-sized firm mass on the anterior vaginal wall. Computed tomography, magnetic resonance imaging (MRI), cystourethroscopy and the histopathological findings of the biopsied specimen revealed adenocarcinoma of the urethra. Anterior pelvic exenteration and ileal conduit urinary diversion were performed and the final pathological diagnosis was clear cell adenocarcinoma of the urethra, pT3, pN2. No further adjuvant therapy was conducted. She remains alive 6 months after surgery in spite of paraaortic and inguinal lymph node metastases.

Anterior decompressive surgery with spinal fusion is considered an effective treatment for thoracolumbar fractures and tumors. However, it is also known to be associated with considerable surgical approach-related trauma. The purpose of this study was to show that lumbar corpectomy and spinal reconstruction can be performed via a minimally invasive retroperitoneal (MIR) approach and therefore, the surgical approach-related trauma can be reduced. The hospital records and radiological studies obtained in five patients (mean age 67.4 years, range 59-76 years) who underwent lumbar corpectomy and spinal fusion via an MIR approach were studied retrospectively. Four patients presented with osteoporotic compression fractures at L-2 and L-3 and one patient with metastatic disease at L-4 from prostate cancer. In all patients neurological deficits due to cauda equina compression were demonstrated. The MIR approach provided excellent exposure to facilitate complete spinal decompression and reconstruction in all patients, as verified on follow-up x-ray studies. All patients improved clinically. A 1-year follow-up record, available for four patients, showed evidence of continuing clinical improvement and, radiographically, a solid fusion or a stable compound union and anatomically correct reconstruction. The MIR approach allows anterior lumbar spine surgery to be performed less invasively. The efficacy and safety of this technique compared with the conventional retroperitoneal approach to lumbar spine surgery should be further investigated in a larger series.

Pulmonary nodules that are surrounded by aerated lung cannot be visualized with sonography. Therefore, percutaneous biopsy must be guided with computed tomography or fluoroscopy. Although this restriction only applies to central lung nodules, it has permeated referral patterns for other thoracic lesions and has retarded the growth of ultrasound-guided interventions. Nevertheless, sonography is an extremely flexible modality that can expeditiously guide many biopsy procedures in the thorax. Peripheral pulmonary nodules can be successfully biopsied with success rates exceeding 90% and complications rates of less than 5%. Orienting the probe parallel to the intercostal space facilitates biopsies of peripheral pulmonary nodules. Anterior mediastinal masses that extend to the parasternal region are often easily approachable provided the internal mammary vessels, costal cartilage, and deep great vessels are identified and avoided. Superior mediastinal masses can be sampled from a suprasternal or supraclavicular approach. Phased array probes or tightly curved arrays may provide improved access for biopsies in this location. Posterior mediastinal masses are more difficult to biopsy with ultrasound guidance because of the overlying paraspinal muscles. However, when posterior mediastinal masses extend into the posterior medial pleural region, they can be biopsied with ultrasound guidance. Because many lung cancers metastasize to the supraclavicular nodes, it is important to evaluate the supraclavicular region when determining the best approach to obtain a tissue diagnosis. When abnormal supraclavicular nodes are present, they often are the easiest and safest lesions to biopsy.

The authors describe a technique for total L-5 spondylectomy and reconstruction of the lumbosacral junction. The technique, which involves separately staged posterior and anterior procedures, is reported in two patients harboring neoplasms that involved the L-5 level. The first stage consisted of a posterior approach with removal of all posterior bone elements of L-5 and radical L4-5 and L5-S 1 discectomies. Lumbosacral and lumbopelvic instrumentation included pedicle screws as well as iliac screws or a transiliac rod. The second stage consisted of an anterior approach with mobilization of vascular structures, completion of L4-5 and L5-S1 discectomies, and removal of the L-5 vertebral body. Anterior lumbosacral reconstruction included placement of a distractable cage and tension band between L-4 and S-1. Allograft bone was used for fusion in both stages. No significant complications were encountered. At more than 1 year of follow-up, both patients were independently ambulatory, without evidence of recurrent or metastatic disease, and adequate lumbosacral alignment was maintained. The authors conclude that this technique can be safely performed in appropriately selected patients with neoplasms involving L-5.

Carcinoma of the vagina is a very rare disease. Primary vaginal carcinoma tends to spread by local invasion of the adjacent pelvic organs (without any kind of metastases) and secondarily through lymphatic channels. The aim of this report is to add observations concerning the surgical treatment of this rare occurrence of carcinoma. The 33-year old patient's history began with an acute urinary retention which imposed bladder catheterization. Local examination revealed a hard 3/3 cm large mass on the middle third of the anterior vaginal wall, invasive in the urinary bladder. Cystoscopic examination confirmed the tumor invasion in the trigone. Biopsy specimens of the tumor and histological examination showed carcinoma. Anterior pelvic exenteration with pelvic lymph nodes dissection and total colpectomy was performed and the patient received a continent urinary diversion to the skin (modified Indiana pouch), ovary transposition, vaginal reconstruction with gracilis myocutaneous flaps. Postoperative evolution was uneventful. Organ reconstruction surgery including continent urinary diversion, vaginal reconstruction will significantly improve the quality of life and don't change the body image of the patients after pelvic major surgical procedures such pelvic exenteration.

Only 6 cases of pyogenic spondylitis following vertebroplasty or kyphoplasty have been reported, and their causes remained unclear. The authors report on 4 cases of delayed pyogenic spondylitis (DPS) following vertebroplasty or kyphoplasty for osteoporotic compression fractures and metastatic disease. Four patients presented with DPS after vertebroplasty or kyphoplasty and underwent surgical treatment. Clinical history, laboratory examination, and MR imaging confirmed the diagnosis of DPS. Anterior debridement, reconstruction, and posterior instrumented fusion were performed. The mean interval for the delayed occurrence of pyogenic spondylitis after surgery was 12.3 months. The infections were primarily bacterial in origin, but most patients also suffered diverse medical comorbidities. Despite successful treatment of the infections, comorbidity was and is a factor that compromises good results. Medical comorbidities associated with compromised immunity may increase susceptibility to DPS after vertebroplasty or kyphoplasty. In cases of incapacitating back pain after a pain-free period following either of these surgeries, evaluation of the erythrocyte sedimentation rate and C-reactive protein level and examination of contrast-enhanced MR imaging studies are essential to rule out delayed vertebral infection. Surgical treatment requires cement removal and anterior reconstruction with or without additional posterior instrumented fusion.

Anterior decompression in spinal metastases of the corporal type with impending (n = 5) or present (n = 36) neurological complications was performed in 41 patients. For reconstruction, a titanium cylinder was inserted after spondylectomy and augmented with an anterior plate. The titanium implant can easily be adjusted to the length needed without necessitating expensive additional equipment. Outside the patient the implant is filled with polymethylmetacrylate, facilitating plate transfixation for rotational locking. There was a 30-day mortality of 9.7%. Pain relief was apparent in 38 of 41 patients (92.7%), and motor improvement was manifest in 31 of 35 cases (88.6%). Six patients did not present with any neurological symptoms pre- or postoperatively. Neurological deterioration was registered in only 1 case (2.4%). Surgical efficacy was maintained until the death of the patients. Though tumor recurrence at a different spinal level led to consecutive surgery in 5 patients, no implant dislocation occurred during the observation period (maximum 44 months), characterizing the procedure as a mechanically reliable and safe technique.

Anterior decompression and reconstruction have been used for the treatment of various conditions at the lumbosacral junction, particularly those necessitating corpectomy because of destruction due to primary or secondary bone tumour or infection. The authors conducted a prospective study on 15 consecutive patients who underwent L5 (L4-L5 in 3 cases) corpectomy for tumour or infection, between 2000 and 2005: 6 for tumour, 7 for tuberculous spondylitis, and 2 for pyogenic spondylitis. Corpectomy, bonegrafting (tricortical iliac bone graft or titanium mesh-bone graft) and anterior-only instrumentation (screw-plate or screw-rod) were performed via a retroperitoneal approach. One month of bed rest yielded additional stability. The patients were followed up for an average of 39.7 months (range: 7-73 months). Pain relief and neurological recovery were excellent. Solid fusion was obtained in all patients. There were no cases of plate or screw failure. Three patients with metastases died after 7, 17, and 13 months, in spite of successful fusion. No recurrence was noted in all 9 patients with spinal infection. The results observed indicate that grafting and anterior-only instrumentation and grafting is an effective and safe procedure for reconstruction of the lumbosacral junction following L5 (or even L4-L5) corpectomy; it may obviate the need for additional posterior stabilization in selected patients.
