A 45-year-old man presented with lower back pain and pain in the right leg of 3years duration. A plain radiographic examination revealed grade I isthmic spondylolisthesis, with instability at L4-5. Computed tomography and magnetic resonance imaging demonstrated bilateral foraminal stenosis, with soft foraminal disc herniation on the right side at the L4-5 level. He underwent anterior lumbar interbody fusion[ALIF] with percutaneous posterior fixation[PF] at the L4-5 level. Without removing the posterior bony structures, removal of foraminal disc herniation and reduction of spondylolisthesis were successfully performed using ALIF with percutaneous PF. When there is no hard disc herniation or lateral recess stenosis, ALIF with percutaneous PF can be one of the treatment options for isthmic spondylolisthesis, even in the presence of foraminal disc herniation, as in our case.

Displaced intra-articular calcaneal fractures are difficult to treat because of complex anatomy and high soft tissue complications. Various surgical approaches have been introduced to solve these problems, but the treatment remains complex. Recently, clinically and radiographically superior results were reported using a subtalar arthroscopy in reducing the posterior facet in both percutaneous and open approaches. In the percutaneous approach, the arthroscopically assistant percutaneous approach must be selected carefully for mild-to-moderately displaced fractures because of the limited view. In the open approach, there is little evidence of the utility of subtalar arthroscopy. Therefore, intraoperative arthroscopy should always be used in conjunction with fluoroscopy to achieve reduction and assess the internal fixation placement.

Interventional recanalization is an effective treatment option for postoperative portal vein occlusion. A transhepatic or transsplenic approach is preferred, whereas a percutaneous transmesenteric route enables antegrade cannulation. Here, we present a case of successful percutaneous transmesenteric recanalization in a patient with a postoperative portal vein graft occlusion.

Insufficiency fractures of the sacrum are relatively common and cause severe low back and buttock pain. Percutaneous vertebroplasty is effective for treating vertebral compression fractures. We present a case of percutaneous sacroplasty for the treatment of low back and buttock pain in a sacral insufficiency fracture. A 79-year-old male with non-small lung cancer presented with severe low back and buttock pain after series of radiation treatments. Preoperative MRI showed both a sacral ala and S2 metastatic insufficiency fracture. An epidural port was inserted for continuous morphine infusion and sacral nerve root blocks were performed. However, his pain did not diminish and we attempted percutaneous sacroplasty. Both sides of the sacroplasty were done with a fluoroscopy-guided technique with 1.7 ml and 2.3 ml of bone cement injected into the right and left sacral ala. Pain relief was significant and the patient was able to sit down 1 day after the procedure.

We present a case of an acute psoas muscle hematoma following percutaneous endoscopic lumbar discectomy. A 60-year-old female who presented with far lateral lumbar disc herniation underwent endoscopic discectomy on the right side at the L4-5 level. On the second postoperative day, the patient complained of severe right flank and leg pain and her blood pressure decreased. A computed tomography scan showed a large acute psoas muscle hematoma at right L4-5 level. The patient was transfused with packed red blood cells and placed at absolute bed rest. After observing the patient in intensive care, the severe flank and leg pain subsided, but the mild back pain persisted. Although percutaneous endoscopic lumbar discectomy is an effective minimally invasive surgical technique for the treatment of lumbar disc herniation, this case highlights the inherent risks of acute lumbar segmental vessel injury.

Unstable pelvic ring injuries are potentially life-threatening and associated with high mortality and complication rates in polytrauma patients. The most common cause of death in patients with pelvic ring injuries is massive bleeding. With resuscitation, external fixation can be performed as a temporary stabilization procedure for hemostasis in unstable pelvic fractures. Internal fixation following temporary external fixation of the pelvic ring yields superior and more reliable stabilization. However, a time-consuming extended approach to open reduction and internal fixation of the pelvic ring is frequently precluded by an unacceptable physiologic condition and/or concomitant injuries in patients with multiple injuries. Conservative treatment may lead to pelvic ring deformity, which is associated with various functional disabilities such as limb length discrepancy, gait disturbance, and sitting intolerance. Therefore, if the patient is not expected to be suitable for additional surgery due to a poor expected physiologic condition, definitive external fixation in combination with various percutaneous screw fixations to restore the pelvic ring should be considered in the acute phase. Herein, we report a case of unstable pelvic ring injury successfully treated with definitive external fixation and percutaneous screw fixation in the acute phase in a severely injured polytrauma patient.

Purpose: Diabetic foot gangrene has a high morbidity rate and a great influence on the quality of life. Amputation is an appropriate treatment if conservative treatment is impossible according to the severity of gangrene and infection. The purpose of this study was to evaluate the usefulness of preoperative percutaneous transluminal angioplasty for the postoperative outcome. Materials and Methods: From February 2013 to April 2016, among 55 patients with diabetic foot gangrene, who require surgical treatment, percutaneous transluminal angioplasty was performed on patients with an ankle brachial index (0.9 and stenosis) 50% on angiographic computed tomography. The study subjects were 49 patients, comprised of 37 males (75.5%) and 12 females (24.5%). The mean age of the patients was $70.0{\pm}9.6years$. The treatment results were followed up according to the position and length of the lesion and the changes during the follow-up period. Results: As a result of angiography, there were 13 cases of atherosclerotic lesions in the proximal part, 11 cases in the distal part and 25 cases in both the proximal and distal parts. As a result of the follow-up after angiography, in 13 patients, the operation was not performed and only follow-up and dressing were performed around the wound. Sixteen patients underwent debridement for severe gangrene lesions and 20 patients, in whom the gangrene could not be treated, underwent amputation (ray amputation or metatarsal amputation, below knee amputation). Conclusion: Preoperative percutaneous angioplasty in diabetic foot gangrene patients with peripheral vascular occlusive disease is simple, and 59.2% of the patients with diabetic foot gangrene could be treated by conservative treatment or debridement.

Cervical radicular pain has been recognized as a common cause of neck, shoulder and arm pain. The initial recommended therapy is based on the medical treatment by anti-inflammatory, analgesic agents, rest, traction and physical therapy. In the case of failure with these therapies, the classical alternative is a surgical discectomy, but this is associated with numerous risks inherent to invasive procedures. As a result, a number of percutaneous intradiscal therapies have developed over the last 3 decades, which have specifically focused on the pathology of the disc. However, these treatments have considerable limitations and success rates, and none allow for the extraction of a quantifiable amount of nucleus pulposus via a 17 gauge introducer using fluoroscopic guidance alone. Herein, we describe our experience using a $Dekompressor^{(R)}$ on a 52 year-old female patient with a cervical disc herniation. Percutaneous decompression in the treatment of cervical disc herniation was successfully performed, with a good outcome.

Purpose: It is even less common traumatic pseudoaneurysm of the superficial temporal artery and rare with fewer than 200 cases reported in the recent literature. Most common causes of traumatic pseudoaneurysm is sequelae of blunt, penetrating, or iatrogenic surgical trauma. The diagnosis is based on physical findings and can be confirmed by duplex ultrasonogram, computed tomography, and angiography. Surgical resection, percutaneous embolization and conservative treatment have all been used to treat pseudoaneurysm. However recently, non invasive technique like percutaneous thrombin injection under ultrasonographic guidance has been done rather than surgical ligation. In this report, we proposed the several treatment options such as conservative treatment, thrombin injection, and surgical ligation according to the multifarous conditions of pseudoaneurysm, patient, and causes. Methods: We describe two cases of traumatic pseudoaneurysm of superficial temporal artery in which CT angiography was effective in diagnosis and characterization. One is chronic pseudoaneurysm after traffic accident, which is fusiform shape and small size. Since the patient prefered it, we proposed percutaneous thrombin injection first. But we recognize that this method failed, we used surgical ligation according to information of CT angiographic findings. The other is acute pseudoaneurysm after blunt trauma, which is large size accompanying large hematoma. So we proposed compressive dressing and aspiration of hematoma. Results: Two cases were well treated with no recurrence or complication. Conclusion: In conclusion, when selecting a treatment options, followings should be considered: pseudoaneurysm in CT angiography, chronicity, cause, and patient's preference.

Background and Objective: Percutaneous ethanol injection therapy has been used in the treatment of the benign thyroid diseases. Although the reported side-effects of the therapy was mild and transient, some side-effects including local or radiating pain are troublesome to the patients. Radioactive iodine-131($Ra-^{131}I$) also has been effectively and safely used for management of the benign thyroid diseases. So we developed the percutaneous intranodular injection therapy of $Ra-^{131}I$ as an alternative of percutaneous ethanol injection therapy. Materials and Methods: From December 1998 to October 1999, we treated 29 outpatients (25 women and 4 men, mean age: $47{\pm}12$ years). Inclusion criteria were follows; age >30 years, cytologically benign, with normal thyroid function, cold nodule on thyroid scintigram, solid or mixed natured nodules in sonographical evaluation. Nodular volume was estimated by sonography according to the ellipsoid formula. $Ra-^{131}I$(0.1mCi/ml) was administered in a single dose injection. Follow-up studies every 3 months consisted of full history, thyroid function test, and sonography. We determined the therapeutic response is effective if the volume reduction of the nodule occurred above 30%. Results: After at least 3 months follow-up, 11 patients showed effective response, 12 patients showed minimal or unchanged response and 6 patients showed progression. Although side-effects such as injection pain, febrile reaction, and hormonal changes were absent, an infectious complication in injection site was developed from 1 case. Conclusion: Although we need a more prolonged follow-up to evaluate the delayed sequelae, we can suggest that percutaneous intranodular injection therapy of $Ra-^{131}I$ may be an attractive non-surgical treatment in selected cases of benign thyroid nodules.
