Effectiveness and Influencing Factors of Percutaneous Transluminal Angioplasty for Stenosis of Transposed Brachiobasilic Arteriovenous Fistula

PURPOSE@#To evaluate effectiveness of percutaneous transluminal angioplasty (PTA) for transposed brachiobasilic arteriovenous fistula (tBBAVF), and to analyze the factors influencing patency after PTA.@*MATERIALS AND METHODS@#In 101 patients who underwent operation for tBBAVF from January 2006 to February 2008, we identified 42 patients undergoing PTA. We conducted a retrospective analysis of sequential PTAs in these patients from 2006 to 2017.@*RESULTS@#A total of 100 PTAs were performed. The technical success rate was 93% and the clinical success was 100%. Only ruptures occurred in 12% as minor complications. Primary patency rate was 61%, 29%, 7%, and secondary patency was 91%, 82%, 59% at 6, 12, and 24 months, respectively. Primary patency rate was lower in tBBAVF with rupture (p = 0.024). Secondary patency rate was significantly lower in the diabetes (p = 0.002).@*CONCLUSION@#Repetitive PTAs in tBBAVF are acceptable due to excellent secondary patency. Primary patency of tBBAVF is low in patients with rupture. Diabetes itself has a significant effect on secondary patency.

Aberrant Ovarian Artery Arising from the Common Iliac Artery: Case Report

A 46-year-old Vietnamese woman received embolization therapy in order to control postpartum hemorrhage. Angiography revealed an aberrant ovarian artery arising from the right common iliac artery. Superselective catheterization and subsequent embolization of the aberrant ovarian artery and bilateral uterine arteries were performed. Precise knowledge of the anatomic variations of the ovarian artery is important for successful embolization.

Sonographic Features of Dual Ectopic Thyroid: Report of Two Cases

Ectopic thyroid is an uncommon congenital abnormality, but ectopic thyroid tissue can be present anywhere along the course of the thyroglossal duct and the embryologic descent from the base of the tongue. We report here on two cases with the ultrasonograpic findings of dual ectopy of the thyroid, and these findings were well correlated with the findings of nuclear scintigraphy.

A Case of Atypical Distribution of Pulmonary Tuberculosis in Bedridden Patient with Quadriplegia / 결핵및호흡기질환

Pulmonary tuberculosis has intermediate prevalence in Korea. It is known that tuberculosis infection predominantly involves the upper lobes, based on the fact that multiplication of Mycobacterium tuberculosis is favored in areas with decreased pulmonary blood flow, impaired lymphatic drainage, and high oxygen tension. We report this case of a 40-year-old man who was brought to our hospital with hemoptysis and dyspnea. Prior to admission, the patient had been in a bedridden state for 15 years due to an injury of the cervical spine 4~5. A 3-Dimensional computed tomography showed predominantly longitudinal distribution of centrilobular nodules along the anterior chest wall, in the left lung. MTB-PCR and AFB culture of bronchial washing fluid revealed pulmonary tuberculosis. This case shows that long-standing supine posture and decreased motion of the anterior chest wall may change the distribution of preferential infection site of Mycobacterium tuberculosis in the lung, resulting in a ventral predominance of tuberculosis infection in the quadriplegic patient.

A case of lung metastasis of papillary thyroid carcinoma presenting with tuberculous pleurisy / 대한내과학회지

Papillary thyroid carcinoma is the most prevalent type of thyroid cancer. Metastasis of this carcinoma commonly occurs in the lung and has been reported to present 5 to 30 years after the initial diagnosis of thyroid cancer. Pleural effusion can mask this metastatic spread. In patients with pleural effusion, laboratory measurement of the adenosine deaminase (ADA) level in the pleural fluid can be effective in identifying and ranking pulmonary metastasis in the differential diagnosis. A 70-year-old female patient visited our hospital with dyspnea. She presented with a considerable amount of pleural effusion. A pleural biopsy was performed and the Ziehl-Neelsen stains revealed a few acid-fast bacilli, but the ADA level in the pleural fluid was 2.4 IU/L. After drainage of the pleural effusions, we discovered pulmonary nodules by computed tomography (CT), which were later diagnosed through histologic examination as pulmonary metastasis from papillary thyroid carcinoma. We report this case.

Hounsfield Number Measurement after a Uterine Fibroid Embolization: Significance as a Predictive Factor of Embolization Success

PURPOSE: To assess the usefulness of the Hounsfield number, measured by a non-contrast enhanced pelvic CT, after a uterine artery embolization as an index of the successful outcome of a uterine fibroid embolization (UFE). MATERIALS AND METHODS: The study subjects included 15 women (age range: 28-49 years, mean age: 36.4 years) diagnosed with symptomatic uterine myomas and seen from March 2003 to August 2005. A non-contrast enhanced pelvic CT scan was performed six hours after a uterine artery embolization. The global and maximal CT numbers were measured for each myoma. In addition, a pelvic MRI was performed to measure the volume of each myoma prior to and 6 months after the UFE. The relationship between fibroid volume reduction and the global CT number were prospectively analysed. RESULTS: The mean global CT number was 91.25 HU in Group I and 40.8 HU in Group II. Further, the mean fibroid volume reduction rate was 73% in Group I and 10% in Group II (p < 0.05). CONCLUSION: The global CT number measured by a non-contrast enhanced pelvic CT is a useful predictive factor of a successful uterine fibroid embolization.

Subcutaneous Cavernous Hemangioma of the Breast: A Case Report

Vascular tumors of the breast are uncommon and occur, for the most part, in the form of angiosarcomas. Benign breast hemangiomas are especially rare, with few reports existing in the literature. We report a case of a subcutaneous cavernous hemangioma of the breast and describe the sonographic, MRI findings and pathologic features.

Mucocele of the Remnant Appendix Following Incomplete Appendectomy: A Case Report

Appendiceal mucoceles are rare lesions. There has been only one report of a mucocele of the remnant appendix not communicating with the cecum. We report a remnant appendiceal mucocele following an incomplete incidental appendectomy, which presented as a lobulated cystic mass on ultrasonography and a cystic mass with an irregular wall on computed tomography. A borderline malignant mucinous tumor of the appendix was diagnosed.

Early Ultrasonographic Findings after a Uterine Fibroid Embolization: The Value of Differentiate from Procedure-Related Uterine Infection

PURPOSE: To evaluate the early ultrasonographic (US) findings from the uterus and myoma after a uterine fibroid embolization (UFE). MATERIALS AND METHODS: From March 2004 to January 2006, eleven patients (27-48 years, mean: 37 years) with UFE to treat symptomatic uterine myoma, were retrospectively reviewed. A serial follow up gray-scale and color Doppler US were performed from one day to two weeks following a UFE. The US findings were evaluated for the presence and distribution pattern of air, time of air loss, and presence of fluid collection in the uterine cavity and color Doppler (SD Comment: Doppler is name. Should perhaps be upper case) signal. RESULTS: Numerous high echoes with reverberation artifacts (which suggest air), were observed within the myoma (in all cases), one day after UFE. A branching linear echo pattern was observed in 4 cases (36%), whereas scattered echoes were observed in 7 cases (64%). Progressive loss of air, within 7 days of a UFE, was observed in 9 cases (82%), whereas 2 cases (12%) were observed within 14 days of a UFE. Abnormal fluid collection in the uterine cavity and a color Doppler signal within the myoma was not observed for all cases. CONCLUSION: Branching or scattered echoes (suggesting air), are normally found within the myoma after a UFE, but these echoes disappeared within 2 weeks. These early US findings can be useful in differentiating from myoma infections after a UFE.

Tuberous Sclerosis Manifested by Spontaneous Rupture of Renal Angiomyolipoma in a Patient with Polycystic Kidney Disease / 대한신장학회지

Tuberous sclerosis is an autosomal dominant disorder characterized by seizure, mental retardation and harmatomatous lesions in multiple organs. The renal lesions of tuberous sclerosis are multiple angiomyolipomas often associated with cysts of various sizes. A 47-year-old man who had been on hemodialysis for 12 years was admitted to our hospital because of sudden onset of right flank pain. He had polycystic kidney disease and adenoma sebaceum. Abdominal computed tomography showed an enlarged right kidney with massive hemorrhage, and renal arteriography showed massive bleeding. Immediate transarterial embolization and radical nephrectomy on the right kidney was done. Pathologic examination revealed ruptured renal angiomyolipoma, confirming that he had contiguous gene syndrome. We experienced a case of tuberous sclerosis with spontaneous rupture of renal angiomyolipoma in a hemodialysis patient with autosomal dominant polycystic kidney disease.

The Usefulness of Transcatheter Arterial Embolization for Panfacial Injury

PURPOSE: A life-threatening hemorrhage resulting from a severe facial fracture is rare, but it needs a prompt and aggressive treatment. Especially, a massive oronasal bleeding combined with midfacial fracture which may result from the rupture of the internal maxillary artery. With the recent advances in the radiologic intervention, its use has increased for managing these life threatening case. We reviewed its usefulness with our experiences and literatures. METHODS: A retrospective review was performed to determine the usefulness of the transcatheter arterial embolization in patients with panfacial trauma. If the vital signs were unstable, cardiopulmonary resuscitation was performed. Oronasal bleeding was controlled with nasal packing and electrocautery. All injured regions were studied by radiologic study including CT. Even after primary management, if the oronasal bleeding was persistent, radiologic intervention was performed 10 patients were treated with transcatheter arterial embolization and the bleeding focus controlled by embolization with polyvinyl alcohol and gelfoam. RESULTS: After the intervention, the vital signs became stable and there were no complications from embolization in the follow-up for 6 months. Also patients could recover through appropriate operations. CONCLUSION: Transcatheter arterial embolization for maxillofacial injury has many advantages for both, the doctor and the patient. First, less pain is induced than a compression device or an operation, which is another way to treat oronasal bleeding. Second, it does not need general anesthesia. And through a single procedure not only we can know the accurate bleeding point, but we can also bleeding by embolization.

Selective Uterine Artery Embolization for Management of Interstitial Ectopic Pregnancy

Interstitial ectopic pregnancy is a rare condition of pregnancy and may be very dangerous if not identified and treated urgently. We report a case of successful treatment of an interstitial pregnancy using selective uterine artery embolization. A 27-year-old woman with interstitial pregnancy was treated by uterine artery embolization after failure of systemic methotrexate treatment. Her serum beta-human chorionic gonadotropin (β-hCG) was undetectable one month after the therapeutic embolization and transvaginal sonography 31 days after embolization showed normal endometrium and cornu. The patient achieved a normal pregnancy eight months after embolization.

High-Resolution Ultrasonography (US) of Appendiceal Specimens: Differentiation of Acute Non-perforated Appendicitis from Perforated Appendicitis

PURPOSE: To analyze surgical specimens from patients with acute non-perforated and perforated appendicitis using high-resolution ultrasonography (US), and to correlate the US features with the pathologic findings. MATERIALS and METHODS: One hundred and six surgical appendix specimens obtained from patients with suspected acute appendicitis were evaluated. The following US features were evaluated for differentiating acute non-perforated appendicitis from perforated appendicitis: circumferential loss of the echogenic submucosal layer, disruption of the serosal layer, asymmetrical wall thickening, the sum of opposing walls > or = 9 mm and the presence of appendicoliths. The sensitivity and specificity of the US findings for diagnosing perforated appendicitis were determined. RESULTS: All US features were detected significantly more often in the perforated appendicitis group of specimens. The disruption of the serosal layer was the most significant independent predictor of perforation (p or = 9 mm, and the presence of appendicoliths individually was 84.6%, 69.2%, 61.5%, 73.1% and 46.2%, respectively. The specificity for all of these findings was 86.3%, 98.7%, 95.0%, 85.0% and 85.0%, respectively. CONCLUSION: High-resolution US of appendiceal specimens was very useful for differentiating acute non-perforated from perforated appendicitis.

Usefulness of Modified Intravenous Analgesia: Initial Experience in Uterine Artery Embolization for Leiomyomata

PURPOSE: We wanted to evaluate the usefulness of modified intravenous analgesia for the management of pain during uterine artery embolization for leiomyomata. MATERIALS AND METHODS: Between April 2004 and July 2004, 15 patients with symptomatic fibroids underwent uterine artery embolization and pain management. Except the three patients for whom the Visual Analogue Scale (VAS) score was not obtained, twelve patients were included in this study. For pain management, epidural PCA (Patient Controlled Analgesia) was used in two patients, intravenous PCA was used in two patients and modified intravenous analgesia injection was used in eight patients. For all the patients, we used the 2.8 Fr coaxial microcatheter and 500-710 μm PVA particles for the embolic materials. The protocol of the modified intravenous analgesia injection was as follow, 1) prior to femoral artery puncture, 30 mg of ketorolac tromethamine (Tarasyn) was injected via an intravenous route. 2) At the time that the one side uterine artery embolization was finished, normal saline mixed 150 mg meperidine (Demerol) was administered through the side port of the intravenous line that was used for hydration. 3) Additional ketorolac tromethamine 30 mg was injected after 6 hour. The VAS score and side effects were then checked. After 12 hours, the VAS score was rechecked. If the VAS score was above 4, this was considered as failure of pain management. The VAS scores, complications and side effects for the modified intravenous analgesia injection were compared with that of IV PCA and epidural PCA. RESULTS: The average VAS score of the modified intravenous analgesia injection, intravenous PCA and epidural PCA was 1.4, 1 and 0, respectively; the number of additional intramuscular injections of analgesia was 0.5, 0.5 and 0, respectively. All the patients who underwent epidural PCA had back pain at the puncture site and 1 patient who underwent modified intravenous analgesia injection experienced mild dyspnea, but they easily recovered with such conservative treatment as an oxygen supply. No serious side effects or complications developed from the modified intravenous analgesia injection. CONCLUSION: Modified intravenous analgesia injection is well tolerated for the pain management of uterine fibroid embolization and it is a relatively inexpensive, safe method as used in our radiologic practice.

Bilateral Uterine Arterial Embolization for Treatment for Uterine Myoma / 대한산부인과학회지

OBJECTIVE: The purpose of this study is to evaluate the effectiveness and safety of uterine artery embolization for the treatment of symptomatic leiomyomas in the patients who want to preserve uterus, want fertility or feel fear for operation. METHODS: From January 2003 to June 2005, among the patients with symptomatic uterine leiomyoma, fifteen women who wanted to preserve uterus or wanted fertility or had fear for operation were included in this retrospective study. Bilateral Uterine artery embolization (UAE) was performed. At the preprocedure and at 2, 6, and 12 weeks of postprocedure, transvaginal ultrasonography was performed for all patients. Clinical symptoms and follow-up information for each patient were evaluated. RESULTS: 15 leimyomas were treated with UAE. The initial mean volume of leiomyomas was 55.4 (46.3-67.4) cm3. The mean volume decrease was 58.6+/-9.7%, 77.5+/-12.3%, 86.8+/-23.5% at 2, 6, 12 weeks. The outcome of clinical symptoms were as followed; 'much improved' 20% (3/15), 'somewhat improved' 60% (6/15), 'no improvement' 20% (3/15), 'somewhat worsen's 0% (0/15), and 'much worsen' was 0% (0/15). There was no case of hysterectomy or myomectomy after UAE. And also no case of increasement of volume nor worsening of clinical symptoms were found. Lower abdominal pain was the most common symptoms after UAE, but complications were not detected. CONCLUSION: In this study, UAE to treat patients with uterine leiomyoma is proved to be effective not only in volume reduction, but also in symptom improvement. And it is a relatively less-invasive procedure which decreases the risk of side effects of operation. Above all things, it preserves fecundity in young women. Therefore, UAE is very effective and safe procedure in the treatment of symptomatic uterine leiomyoma.

Ovarian Protection by Selective Coil Embolization of a Uteroovarian Anastomosis before Uterine Fibroid Embolization: A Report of Two Cases

Premature menopause can be developed as a result of undesired nontarget ovary embolization during the performance of uterine fibroid embolization. The etiology of ovarian failure after uterine fibroid embolization is not yet clearly defined, but one of the leading possibilities is nontarget embolization of the ovaries. We report here on two cases in which superselective coil embolization of distal uterine artery collateral pathways to the ovary was performed during uterine fibroid embolization.

Granular Cell Tumor Simulating Breast Malignancy: A Case Report

Granular cell tumor is a rare and usually benign tumor that occasionally involves the breast. The physical examination, the mammographic and ultrasonographic findings and the pathologic findings are often suggestive of carcinoma. We report here a rare case of granular cell tumor of the breast that mimicked carcinoma on the mammography, ultrasonography and MR imaging.

A Case of Transvaginal Expulsion of Intramural Leiomyoma after Uterine Artery Embolization / 대한산부인과학회지

Uterine artery embolization for the treatment of uterine leiomyomas is gaining acceptance as an effective alternative to surgical treatment in preserving uterus and reducing symptoms. Vaginal expulsion of leiomyomas after UAE is uncommon, and has been regarded as a side effect of the procedure, as well as a natural phenomenon of treatment response. A-28-year-old unmarried woman who has been suffered from menorrhagia underwent UAE. MRI revealed the remnant leiomyomas were reduced in size and volume and also symptoms of leiomyomas were much improved. After 6 month, We've made sure about non-visualization of leiomyoma on follow-up pelvic dynamic MRI. We report this rare case of vaginal expusion of intramural leoimyoma with a brief literature.
