Selective Internal Iliac Artery Oxaliplatin Infusion： Another Facultative Treatment to Unremitting Hematuria in Stage T4 Bladder Carcinoma

OBJECTIVE To observe and evaluate the value of utilizing selective internal iliac artery infusion and selective internal iliac artery embolization for the treatment of unremitting gross hematuria of stage T4 bladder carcinoma. METHODS Fifty-eight stage T4 bladder carcinoma patients were selected. The patients were grouped to the TAI group and the TAE group. The main symptom of hemorrhage was gross hematuria. None of the patients in our study could receive trunk embolization. The infusion plan was oxaliplatin （100 mg/m2） and epirubicin （EPI 50mg/m2）. Embolization was done with coils or strips of gelatin sponge. The duration of gross hematuria was observed. Routine urinalysis and routine blood examination were performed. EORTC QLQ-C30 was used to evaluate the quality of life before and after treatment. RESULTS Gross hematuria and hematuria by light microscope in all patients were reviewed. Resolution time of gross hematuria in the TAI group was 6.7 ± 1.8 days and that in the TAE group was 3.5 ± 0.7 days. The changes in routine urianlysis, routine blood examination and EORTC QLQ-C30 are shown in Figs.l-3. Gross hematuria disappeared in both groups within 7 days after treatment, but the time for the gross hematuria to resolve in the TAE group was much less than that in TAI group （t = 2.51, P 〈 0.01）, and there were no significant differences in the 7th and 21st day between the 2 groups. On the 90th day, the number of erythrocytes in the urine was near 30, close to gross hematuria. The EORTC QLQ-C30 scores decreased after interventional therapy in both groups, which means that quality of life was increased, but there were no significant differences between the 2 groups. CONCLUSION Selective internal iliac artery infusion and selective internal iliac artery embolization are safe, and, in our study, therapeutic efficacy was satisfactory in treating unremitting gross hematuria of stage T4 bladder carcinoma in patients who could not receive trunk embolization. TAE can stop gross hematuria in the short term, but it can be used just once and the long-term therapeutic effect is not satisfactory. TAI had a therapeutic effect similar to TAE, but for a shorter duration, and TAI can be performed multiple times. TAI is one of the facultative treatments for treating gross hematuria of stage T4 bladder carcinoma.

Necrosis of a large hepatic tumor after hemorrhage and subsequent selective arterial embolization

This case report describes a young female patient presenting with acute intra-abdominal hemorrhage originating from a large tumor in the liver, most likely a hepatocellular adenoma. The bleeding was stopped by selective embolization of right hepatic artery branches. Subsequently, partial hepatectomy was performed after 6 mo. Macro- and microscopic examination showed complete necrosis and absence of tumorous tissue. The patient was discharged without complications, and subsequent follow-up until 22 mo after resection did not reveal any new lesions in the liver. This case emphasizes the signifi cance of selective arterial embolization in the management of bleeding liver tumors and questions the need for (partial) hepatectomy after this procedure in selective cases.

Renal artery embolization in the treatment of urinary fistula after renal duplication:A case report and review of literature

BACKGROUND Duplicate renal malformation is a congenital disease of the urinary system,with an incidence rate of 0.8%.Surgical treatment is suitable for symptomatic patients.Urinary fistula is one of the complications of heminephrectomy.Long-term urinary fistula has a great impact on patients'lives.CASE SUMMARY This article mainly reports on a 47-year-old man with duplication of kidney deformity,long urinary fistula after partial nephrectomy,and no improvement after conservative treatment.We have achieved positive results in the arterial embolization treatment of the residual renal artery,indicating that selective arterial embolization is a good way to treat urinary fistula after partial nephrectomy.It is worth noting that this patient violated the Weigert-Meyer law,which also gave us more consideration.CONCLUSION Renal artery embolization may be a simple and safe method to treat urinary fistula inefficacy with conservative treatment.

Hereditary hemorrhagic telangiectasia involving portal venous system:A case report and review of the literature

BACKGROUND Hereditary hemorrhagic telangiectasia(HHT)is an autosomal dominant genetic disorder with an incidence of approximately 1 in 5000 in the general population.It is characterized by vasodilation,which affects specific organs,such as the skin,mucous membranes,brain,lungs,gastrointestinal tract,liver,and others.However,HHT rarely involves the portal venous system to cause serious clinical compli-cations.CASE SUMMARY A 68-year-old woman was admitted to the emergency department due to four consecutive days of abdominal pain and bloody stool and was subsequently diagnosed with HHT.Computed tomography angiography confirmed the presence of an arteriovenous fistula(AVFs).Considering this specific manifestation,whole exome sequencing was performed.After a comprehensive evaluation,a selective superior mesenteric artery embolization was prioritized to avoid intestinal ischemia.The postoperative symptoms of the patient were quickly relieved.Unfortunately,two months post-procedure the patient died from intestinal necrosis and abdominal infection related to remaining AVFs.CONCLUSION For patients with diffuse superior mesenteric AVFs,selective mesenteric arterial embolization may lead to positive short-term outcomes.

Application of super-selective renal artery embolization in renal injuries

Objective: To use super selective renal artery embolization in treatment of patients with renal injuries. Methods: From 1991 to 1998, 11 cases of renal injuries due to different causes underwent super selective renal artery embolization. In these patients, 91% of injury sites were segmental arteries and their branches. All the patients were treated with steel coil for embolization. Results: Nine patients showed prompt cessation of hematuria, and in 2 patients hematuria stopped 2 4 days after embolization. Conclusions: Super selective renal artery embolization (SSRAE) is suitable for severe hematuria, limited size of kidney injuries, stable hemodynamic parameters after conservative treatment and low reserve of renal function. Steel coil is an effective embolic material, rapid hemostasis can be fulfilled and renal function can be reserved. Super selective renal artery embolization has low incidence of complications and can shorten hospitalization time.

Treatments for primary aneurysmal bone cysts of the cervical spine： experience of 14 cases

Background Aneurysmal bone cyst （ABC） is a benign lesion with the potential to be locally aggressive.The optimal treatment of cervical spine lesions remains controversial.This retrospective study was designed to evaluate the different treatments for primary ABCs of the cervical spine.Methods This series included eight men and six women diagnosed between 2002 and 2012.A retrospective review of the hospital charts,operating room reports,office charts,and radiographs was performed.The data collected included patient age,sex,radiological features,pathology,treatment method,outcomes,and complications from biopsies and treatments.The mean age at diagnosis was 17.5 years old with a range of 6-35 years.All patients had experienced local pain for a mean of 7.3 months （range,0.5-18.0 months）,and three patients had neurological deficits （one with radiculopathy and two with myelopathy）.The Frankel classification before treatment was E in 12 cases,D in one case,and C in one case.Results Four patients received radiotherapy alone.Ten patients underwent surgery,including five total spondyiectomies,two local resections,and three curettages.Three patients received preoperative selective arterial embolization,and four received adjuvant radiotherapy.The mean follow-up time was 44.5 months （range 12-96 months）,and no recurrence was identified.Three patients with neurological deficits achieved complete recovery,as noted at the final follow-up examination.One patient received radiotherapy without appropriate immobilization as prescribed and developed C1-C2 subluxation with severe spinal cord compression but without myelopathy.He refused further treatment.Conclusions The results can be achieved by different treatments （surgical resection/curettage,selective arterial embolization,and radiotherapy） for ABC of the cervical spine.Reconstruction of stability is also important for the treatment of cervical ABC.
