Objective To retrospectively analysis our experience of embolization of ruptured intracranial aneurysms during the period of cerebral vasospasm (CVS). Methods Thirty-seven patients with ruptured intracranial aneurysms were embolized with electrolytic detachable coils during the period of CVS (days 4 to 14). Group A included the 14 patients with angiographic CVS and group B included 23 patients without angiographic CVS. All except 2 patients were transferred to our department during the CVS period. Results Twelve patients in group A were successfully received the aneurysms embolization and treatment of the CVS with intraarterial papaverine injection and balloon angioplasty. The Glasgow Outcome Scales (GOS) in 3 months were good recovery in 7 patients, moderate disability in 2, severe disability in 1 and dead in 2. Two patients failed the embolization because the microcatheters can't pass the spasmatic parent arteries. All the aneurysms in group B were successfully embolized. The GOS were good recovery in 18 patients, moderate disability in 2, severe disability in 2 and dead in 1. There was no intraprocedural aneurysmal rupture but with 2 thromboembolic events. No rebleeding occurred during the mean 11 months follow-up.Conclusions The so-called “the period of CVS” isn't always associated with CVS in angiograpy. Embolization of ruptured intracranial aneurysms during the period of pure CVS doesn't carry an increased risk. Both the aneurysms and CVS can be treated during the single procedure. It can reduce the rebleeding rate in hospital and improved the prognosis of the patients with CVS.

Objective The Neuroform stent is the first self-expandable intracranial stent designed for the treatment of wide-necked intracranial aneurysms. We report the results of our preliminary experience in combination of this stent and detachable coils to treat patients with wide-necked intracranial aneurysms. Methods From August 2003 to August 2004, 22 patients with 24 wide-necked intracranial aneurysms were treated with combination of Neuroform stents and detachable coils. There are 19 acutely ruptured aneurysms and 5 unruptured aneurysms. Results Twenty-three aneurysms were successfully treated by combination of stents and detachable coils. In one patients with multiple aneurysms, an unruptured small wide-necked aneurysm was successfully treated with the stent deployment but failed coiling. All stents were deployed successfully. Mild stent displacement was found in one patient. Intraaneurysmal contrast media stagnation was not seen immediately after the stents deployment. Total (100%) obliteration of the aneurysm was achieved in 18 aneurysms, and subtotal (more than 90%) obliteration was achieved in 5 aneurysms. All the parent arteries were patency after treatment. In 2 aneurysms, some small coil loops were herniated into the parent artery from the stent struts but did not affect the blood flow within parent artery. No symptomatic brain ischemia was found in perioperative period. Seventeen patients were received a mean of 3 months follow-up and control angiography. No recurrence was found in 16 patients. Recanalization was found in one patient, he received a second embolization and the aneurysm was totally oberliterazation.Conclusions The Neuroform stent is a very safe and effective intracranial stent for treatment of wide-necked intracranial aneurysm. It is very suitable for wide-necked intracranial aneurysm with severely tortuous parent artery. Due to lack of significant radial strength of the stent, the stent can be shifted by a microguidewire or microcatheter when performed superselective catheterization. Because the big struts of this stent, the change of intraaneurysmal hemodynamics after stent deployment was notevident as coronary stent. So dense packing the aneurysm is advocated. Care must be taken when packing the detachable coils after the stent deployment. The administration of dual anti-platelet drug to prevent stent-related thromboembolic complications in the perioperative period is important. Although a good angiographic result is achieved, long-term angiographic follow-up is still necessary.

Group A included the 14 patients with angiographic CVS and group B included 23 patients without angiographic CVS. All except 2 patients were transferred to our department during the CVS period. Glasgow outcome score (GOS) was evaluated 3 months after the treatment. Results Twelve patients in group A successfully received the aneurysm embolization and treatment of the CVS with intraarterial papaverine injection and balloon angioplasty. GOS in 3 months was good recovery in 7 patients, moderate disability in 2, severe disability in 1, and dead in 2, respectively. Embolization failed in 2 patients because the microcatheters could't pass the spasmodic parent arteries. All the aneurysms in group B were successfully embolized. GOS were good recovery in 18 patients, moderate disability in 2, severe disability in 2, and dead in 1, respectively. There was no intraprocedural aneurysmal rupture but with 2 thromboembolic events. No rebleeding occurred during the mean 11 months follow-up. Conclusions The so-called “period of CVS” isn′t always associated with CVS in angiograpy. Embolization of ruptured intracranial aneurysms during the period of pure CVS doesn′t carry an increased risk. Both the aneurysms and CVS can be treated during the single procedure. It can reduce the rebleeding rate in hospital and improve the prognosis of the patients with CVS.

Objective To evaluate double microcatheter technique for detachable coil treatment of wide-necked intracranial aneurysms. Methods Routine endovascular coil occlusion was not achieved in 6 cases of wide-necked intracranial aneurysms. A second femoral arterial sheath was inserted on the opposite side . A second microcatheter was positioned within the aneurysm. The detachable coils were introduced via double microcatheter simultaneously or successively till the aneurysm were compactly embolized. The coils were detached after satisfactorily positioned. Results Total 6 cases of wide-necked aneurysms were successfully embolized with detachable coil. Aneurysmal sacs were 100% embolized in 2 cases, over 90% in 4 cases. 1 case suffered moderate disablement as a result of complication of. Angiographic follow-up in 5 cases revealed no recurrent or rerupture.Conclusions The double microcathter technique may be an optional method during embolization of some complicated wide-necked aneurysms.

Objective:To evaluate the efficacy and safety of lenvatinib combined with camrelizumab as the second-line treatment for advanced intrahepatic cholangiocarcinoma (ICC).Methods:The clinical data of patients with advanced ICC undergoing the second-line treatment of lenvatinib combined with camrelizumab in the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University from June 2021 to June 2022 were screened and analyzed. A total of 12 patients were enrolled, including seven males and five females, aged (67.5±8.6) years. Response evaluation criteria in solid tumor 1.1 was used to evaluate the efficacy of treatment. The safety assessment adopts the Adverse Event Evaluation Standard 5.0. Kaplan-Meier method was conducted to plot survival curves.Results:Among the 12 patients (after 1-7 cycles of immune and targeted therapy), three achieved partial response, four achieved stable disease, and five were defined as progression disease. Adverse events of different degrees occurred in seven cases, among which three patients had adverse events of grade ≥ 3: one with hypertension, which was managed after antihypertensive and symptomatic treatment; one with elevated serum total bilirubin, which was improved after reducing the dose of lenvatinib; one with liver dysfunction, which was considered as immune-related liver toxicity and alleviated after discontinuing camrelizumab. The 1-month, 3-month, and 6-month survival rates and progression-free survival rates of the patients were 100.0%, 91.7%, 66.7%, and 83.3%, 41.7%, and 25.0%, respectively. The median overall survival of patients was 14.7 months (95% CI: 9.2-21.2) and the median time to progression was 8.0 months (95% CI: 4.1-11.9). Conclusion:Combination of lenvatinib and camrelizumab could bring survival benefits with controllable adverse events as the second-line treatment of patients with advanced ICC.
