RESUMO
BACKGROUND: Total arch replacement (TAR) and the frozen elephant trunk (FET) routinely are performed to treat aortic dissection. When aortic dissection combines with the aberrant right subclavian artery (aRSA), routine TAR+FET will occlude the ostium of aRSA. But there is no consensus regarding the optimal surgical strategy to revascularize the aRSA. We seek an uncomplicated and less time-intensive way to reconstruct the aRSA. METHODS: From July 2020 to April 2022, six patients with aortic dissection and aRSA underwent TAR+FET and intraoperative fenestration on the descending trunk. The mean age of the patients was 51.7 (SD 16.2; range 30.0-72.0). TAR+FET was performed via a median sternotomy and under cardiopulmonary bypass (CPB) and moderate hypothermic circulatory arrest (HCA). A fenestra of descending trunk was made intraoperative. RESULTS: There was no operative death in hospital and follow up. The average aortic cross-clamp time, SACP time, and lower body circulatory arrest time was 138.8 (SD 22.5; range 103.0-156.0) min and 28.3 (SD 3.9; range 25.0-35.0) min. Bleeding, neurological deficit, visceral ischemia, injury to the spinal cord, or organ dysfunction was not observed. Follow-up CTA showed the blood flow of aRSA was patent in all patients. CONCLUSION: TAR+FET and intraoperative fenestration on the descending trunk is an efficacious approach. It also reduces the difficulty of reconstruction the aRSA in aortic dissection patients.

BACKGROUND: The prognosis of hepatocellular carcinoma with portal vein tumor thrombus remains extremely poor. This pilot study aimed to evaluate the technical feasibility, effectiveness and safety of transcatheter chemoembolization for tumors in the liver parenchyma plus intra-arterial ethanol embolization for portal vein tumor thrombus. METHODS: A pilot study was carried out on 31 patients in the treatment group (transcatheter chemoembolization plus intra-arterial ethanol embolization) and 57 patients in the control group (transcatheter chemoembolization alone). Enhanced computed tomography/magnetic resonance images were repeated 4 weeks after the procedure to assess the response. Overall survival and complications were assessed until the patient died or was lost to follow-up. RESULTS: Median survival was 10.5 months in the treatment group (2.4 ± 1.7 courses) and 3.9 months in the control group (1.9 ± 1 courses) (P = 0.001). Patients in the treatment group had better overall survival (at 3, 6 and 12 months, respectively), compared to patients in the control group (90.3% vs. 59.6%, 64.5% vs. 29.8%, and 41.9% vs. 10.6%; p = 0.001). Furthermore, the rate of portal vein tumor thrombus regression was higher in the treatment group (93.1%) than in the control group (32.1%) (P < 0.001). CONCLUSIONS: Based on the results of this study, transcatheter chemoembolization combined with intra-arterial ethanol embolization may be more effective than transcatheter chemoembolization alone for treating hepatocellular carcinoma with portal vein tumor thrombus. Intra-arterial ethanol embolization for treating portal vein tumor thrombus is safe, feasible and prolongs overall survival.

OBJECTIVE: To investigate the feasibility, safety and operative techniques of percutaneous vertebroplasty (PVP) in treating osteolytic bone metastasis of cervical vertebra and reconstructing the function of cervical vertebra. METHODS: From March 2005 to December 2007, 10 patients with osteolytic bone metastatic carcinoma in single cervical vertebral body received PVP, including 5 males and 5 females aged 38-75 years (mean 54.5 years). Among them, 5 patients had primary lung tumor, 1 primary renal tumor, 1 primary breast tumor, 1 primary cervical tumor and 2 unknown primary lesion. The course of disease was 2-4 years. All the patients suffered from obviously cervical pain and limitation of activity, including 4 cases of metastatic tumor of the C2 vertebral body, 2 of C3, 2 of C6 and 2 of C7. The general condition of patients was stable before operation, and no blood coagulation dysfunction, radiculalgia and spinal cord compression were detected. Lateral PVP was performed on 6 cases, approaching between the vertebral artery and the carotid sheath under CT guidance and anterolateral PVP was performed on the rest 4 cases, approaching between the trachea and the internal carotid artery under continuously X-ray fluoroscopy. The amount of bone cement injected was 3-4 mL, and the filling rate was 50%-100%. RESULTS: Without obvious bleeding or organ injury, the puncture was performed successfully on all the patients. Without symptom of spinal cord compression, patients suffered from pain during operation (1 case) and such complications noted by immediate CT or X-rays examination after operation as paravertebral epidural cement leakage (2 cases), transverse foramen cement leakage (1 case) and pinhole reflux (3 cases). The pain of patients was improved to various degree postoperatively, the visual analogue scales score was (5.9 +/- 1.2) points before operation, which was changed to (2.6 +/- 1.2) points at 1 hour after PVP and (1.6 +/- 1.3) points at 1 week after PVP, indicating there was a significant difference between pre- and postoperation (P < 0.05). During the regular follow-up at 1 week, 3 and 12 months after PVP, all patients had no dislocation of cervical vertebra body, spinal cord compression and paralysis. Five patients died from multiple organ failure due to primary tumor progression, including 3 cases at 6 months after PVP and 2 at 12 months after PVP, and the rest 5 patients' cervical pain were under control, with sound functional recovery. CONCLUSION: PVP can relieve pain quickly and reinforce the stability of the vertebral body, and has slight complications; the lateral approach is safe and effective.

BACKGROUND: To investigate the indication, complication and efficacy of bronchial artery embolization for the management of lung cancer with massive hemoptysis. METHODS: Thirty-eight cases of lung cancer with massive hemoptysis were retrospectively analyzed in our hospital from January 1996 to January 2003. All cases presented with acute hemoptysis from 220 to 980 ml daily, with a mean of 290 ml daily. A digital subtracted bronchial arteriogram was perfomed and bleeding arteries were embolized. RESULTS: Hemoptysis decreased gradually in all cases and ceased in 3 or 4 days after embolization. Recurrence was found only in one case 2 months after embolization and second embolization was applied to control hemoptysis. No serious complications occured. CONCLUSIONS: Bronchial artery embolization is safe and efficient for the management of lung cancer with massive hemoptysis.
