Effect of super selective intra-arterial infusion of verapamil for the treatment of cerebral vasospasm after subarachnoid hemorrhage:an efficacy analysis / 中国脑血管病杂志

Objective To investigate the efficacy of super selective intra-arterial infusion of verapamil for the treatment of cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH).Methods From January 2013 to February 2016,the clinical data of 15 patients with subarachnoid hemorrhage (SAH) who had CVS after intracranial aneurysm clipping (n=8) or endovascular treatment (n=7) were analyzed retrospectively.All patients received whole brain digital subtraction angiography (DSA).Microcatheter super selection to spastic arteries was used and verapamil (11.1±3.4 mg) was infused.The findings of whole brain DSA before and after treatments were compared.The blood pressure and heart rate were collected during the treatment and the findings of transcranial Doppler ultrasonography were recorded.The patients were followed up for 6 months and the Glasgow outcome scale (GCS) scores were obtained.Results (1) A total of 20 intra-arterial infusion treatments were performed in 15 cases.They were compared before and after perfusion.CVS was improved on DSA in 14 cases,there was no significant change in on cases.(2) Transcranial Doppler ultrasonography showed that the mean blood flow velocity (mBFV) of the middle cerebral artery was decreased from 181±4 cm/s before the super selective intra-arterial infusion to 126±4 cm/s within 1 hour after treatment.There was significant difference (t=42.46,P0.05).(4) All patients were followed up for 6 months.The GOS score at 6 months:good recovery in 9 cases,moderate disability but could take care of themselves in 3 cases,severe disability and could not take care of themselves in 3 cases,no persistent vegetative state or death.Conclusion Super selective intra-arterial infusion of verapamil can effectively improve the treatment of aneurysmal SAH caused CVS.At the same time,it has no obvious effect on blood pressure and heart rate.

Combined chemotherapy and intra-arterial chemotherapy of retinoblastoma / 소아과

PURPOSE: Retinoblastoma (RB) is the most common primary malignant intraocular tumor in children. Although systemic chemotherapy has been the primary treatment, intra-arterial chemotherapy (IAC) represents a new treatment option. Here, we performed alternate systemic chemotherapy and IAC and retrospectively reviewed the efficacy and safety of this approach. METHODS: Patients diagnosed with intraocular RB between January 2000 and December 2011 at Severance Children's Hospital, Yonsei University, were reviewed. Before February 2010, the primary treatment for RB was chemotherapy (non-IAC/CTX). Since February 2010, the primary treatment for RB has been IAC (IAC/CTX). External beam radiotherapy or high-dose chemotherapy were used as "last resort" treatments just prior to enucleation at the time of progression or recurrence during primary treatment. Enucleation-free survival (EFS) and progression-free survival were assessed. RESULTS: We examined 19 patients (median age, 11.9 months; range, 1.4 to 75.6 months) with a sum of 25 eyes, of which, 60.0% were at advanced Reese Ellsworth (RE) stages. The enucleation rate was 33.3% at early RE stages and 81.8% at advanced RE stages (P=0.028). At 36 months, EFS was significantly higher in the IAC/CTX group than in the non-IAC/CTX group (100% vs. 40.0%, P=0.016). All 5 patients treated with IAC achieved eye preservation, although most patients were at advanced RE stages (IV-V). CONCLUSION: Despite the limitation of a small sample size, our work shows that an alternative combined approach using IAC and CTX may be safe and effective for eye preservation in advanced RB.

Neoadjuvant intra-arterial chemotherapy combined with radiotherapy and surgery in patients with advanced maxillary sinus cancer

PURPOSE: The optimal treatment of advanced maxillary sinus cancer has been challenging for several decades. Intra-arterial chemotherapy (IAC) for head and neck cancer has been controversial. We have analyzed the long-term outcome of neoadjuvant IAC followed by radiation therapy (RT) and surgery. MATERIALS AND METHODS: Twenty-seven patients with advanced maxillary sinus cancer were treated between 1989 and 2002. Five-fluorouracil (5-FU, 500 mg/m2) was infused intra-arterially, and followed by RT (total 50.4 Gy/28 fractions). A planned surgery was performed 3 to 4 weeks after completion of IAC and RT. RESULTS: At a median follow-up of 77 months (range, 12 to 169 months), the 5-year rates of overall survival in all patients were 63%. The 5-year rates of overall survival of stage T3/T4 patients were 70.0% and 58.8%, respectively. Seven of fourteen patients with disease recurrence had a local recurrence alone. The 5-year actuarial local control rates in patients with stage T3/T4, and in all patients were 20.0%, 32.3%, and 27.4%, respectively. Overall response rate after the completion of IAC and RT was 70.3%. During the follow-up, seven patients (25.9%) showed mild to moderate late complications. The tumor extent (i.e., the involvement of either orbit and/or base of skull) appeared to be related with local recurrence. CONCLUSION: Neoadjuvant IAC with 5-FU followed by RT and surgery may be effective to improve local tumor control in the patients with advanced maxillary sinus cancer. However, local failure was still the major cause of death. Further investigations are required to determine the optimal treatment schedule, radiotherapy techniques and chemotherapy regimens.

Clinical observations on mandibular chronic osteomyelitis: Combination therapy of decortication and intra-arterial infusion chemotherapy

Mandibular chronic osteomyelitis with diffuse osteosclerosis is recognized as an intractable infectious disease. We emplyed decortication and intra-arterial infusion of antibiotics in 6 cases. Decortication on the affected mandible was performed with retrocatherization to the superficial temporal artery of affected side under general anesthesia. Antibiotics, IPM/CS or FOMX was used through the artery for 4-11 days. In addition, we administered FOMX, PIPC intravenously for 8-17 days. CT and MRI were taken postoperatively. The postoperative follow-up period ranged from 1 year and 6 months to 2 years and 5 months. Postoperative MR showed that bone marrow signal was recovered to approximately normal in 4 cases. High signal area of bone marrow and osteosclerosis image remained in 2 cases, but showed improvement. The results were satisfactory without recurrence in all of 6 cases.

Methods Chemotherapy of 42 patients were randomly divided into group A (n = 20) with continuously constant arterial infusion, and group B (n = 22) with arterial chrono-modulated infusion. And the toxic effects and efficacy of two groups were compared. Results A significant difference was found in the toxic effects of digestive system between the two groups. The treatment response was similar in the two groups. Conclusions Intra-arterial chrono-chemotherapy may decrease the toxic effects and improve the life quality of these patients.

Intra-arterial infusion chemotherapy in patients with advanced hepatocellular carcinoma with portal vein thrombosis / 대한내과학회지

BACKGROUND: Advanced hepatocellular carcinoma (HCC) with portal vein thrombosis has a poor prognosis and has little hope for meaningful therapy. Transarterial chemoembolization has been performed as a treatment for advanced HCC, but some patients die from progressive liver failure after therapy. This study was undertaken to evaluate the therapeutic effects of intra-arterial infusion chemotherapy in advanced HCC with portal vein thrombosis, and to compare with those of systemic chemotherapy, and to identify prognostic factors that could affect survival. METHODS: Between January 1995 and January 2001, a total of 102 patients with advanced HCC having portal vein thrombosis (TNM stage IVa) were enrolled and divided into 3 groups; Group 1 (n=24) was managed with only conservative treatment, group 2 (n=25) received systemic combination chemotherapy consisting of 5-fluorouracil (FU) + Adriamycin + Mitomycin C, or 5-FU + Etoposide + Cisplatin, and group 3 (n=52) received intra-arterial infusion chemotherapy with 5-FU (250 mg for 5 days) + cisplatin (10 mg for 5 days) via implanted chemoport. RESULTS: One-year survival rates were 0%, 4%, 21%, and median survivals were 2-, 4-, 6 months in group 1, group 2, group 3, respectively (p=0.003). When we divide group 3 patients into long term survivors (more than 8 months) or short term survivors (less than 8 months), former had significantly lower level of serum AST (p=0.032) and alkaline phosphatase (p=0.033). Especially, all female patients (n=9) survived more than 8 months, and had a longer survival than male patients (p=0.000). Other favorable prognostic factors for survival were cirrhosis of Child-Pugh class A (p=0.003), only one major branch involvement of the portal vein by tumor (p=0.005), presence of enhancement of tumor portion in arterial phase of CT scan (p=0.044), presence of enhancement of non-tumor portion in portal phase of CT scan (p=0.029). CONCLUSION: Intra-arterial infusion chemotherapy achieved favorable results in advanced HCC with portal vein thrombosis and showed better survival in selected patients. This therapy can be tried as a treatment option for the management of advanced HCC.
