Catastrophic hemothorax on the contralateral side of the insertion of an implantable subclavian venous access device and the ipsilateral side of the removal of the infected port -A case report-

A Rare Complication of Internal Jugular Vein Cannulation Following Subcutaneous Implanted Port Placement

Port-a-Cath also known as a subcutaneous implantable catheter is a common device used in patients undergoing drug infusions. Port-a-Cath placements are widely used among cancer patients who need multiple intravenous infusions with chemotherapeutic agents. The surgical approach to implanting a Port-a-Cath is associated with risks and benefits; however, it may also be associated with serious complications. We describe a rare case of a large right-sided hemothorax following right internal jugular vein cannulation after Port-a-Cath placement. We discuss possible causes of hemothorax in this patient and describe possible factors such as abnormal anatomy of vessels and body habitus contributing to this complication. We also highlight the use of imaging such as ultrasound-guided techniques and the importance of postoperative chest radiographs to screen for possible complications.

Long-Term Results of a Standard Algorithm for Intravenous Port Implantation

Intravenous ports serve as vascular access and are indispensable in cancer treatment. Most studies are not based on a systematic and standardized approach. Hence, the aim of this study was to demonstrate long-term results of port implantation following a standard algorithm. A total of 2950 patients who underwent intravenous port implantation between March 2012 and December 2018 were included. Data of patients managed following a standard algorithm were analyzed for safety and long-term outcomes. The cephalic vein was the predominant choice of entry vessel. In female patients, wire assistance without use of puncture sheath was less likely and echo-guided puncture via internal jugular vein (IJV) with use of puncture sheath was more likely to be performed, compared to male patients (p < 0.0001). The procedure-related complication rate was 0.07%, and no pneumothorax, hematoma, catheter kinking, catheter fracture, or pocket erosion was reported. Catheter implantations by echo-guided puncture via IJV notably declined from 4.67% to 0.99% (p = 0.027). Mean operative time gradually declined from 37.88 min in 2012 to 23.20 min in 2018. The proposed standard algorithm for port implantation reduced the need for IJV echo-guided approach and eliminated procedure-related catastrophic complications. In addition, it shortened operative time and demonstrated good functional results.

Implantable central venous access device in infants: Long-term results

BACKGROUND

The management of central venous access device (CVAD) is extremely difficult in babies and small infants (BSI). We therefore compared the long-term results and complications of CVAD in BSI with those in children.

METHODS

One hundred and twenty patients were divided into two groups as follows: age <1 year or weight <10 kg (group A; 25 patients); and age ≧1 year and weight ≧10 kg (group B; 95 patients). The clinical results were retrospectively compared between the groups.

RESULTS

Mean age and weight were 12.5 ± 5.9 months and 8.2 ± 1.2 kg in group A, and 78.8 ± 58.9 months and 20.9 ± 13.6 kg in group B. Operation time was 57 ± 29 min in group A and 52 ± 21 min in group B (P = 0.38). The catheter was advanced with difficulty into the central vein in five and in 16 patients (P = 0.77), and surgical complications occurred in one and in seven patients in groups A and B, respectively (P > 0.99). The CVAD remained in place for 627 ± 494 and 550 ± 414 days (P = 0.47) and was removed before treatment completion in five and in 14 patients in groups A and B, respectively (P = 0.54).

CONCLUSION

The clinical results for CVAD in BSI did not differ from those in children. CVAD are useful and safe for the treatment of BSI with serious diseases.

The Treatment Results of a Standard Algorithm for Choosing the Best Entry Vessel for Intravenous Port Implantation

Vascular cutdown and echo guide puncture methods have its own limitations under certain conditions. There was no available algorithm for choosing entry vessel. A standard algorithm was introduced to help choose the entry vessel location according to our clinical experience and review of the literature. The goal of this study is to analyze the treatment results of the standard algorithm used to choose the entry vessel for intravenous port implantation.During the period between March 2012 and March 2013, 507 patients who received intravenous port implantation due to advanced chemotherapy were included into this study. Choice of entry vessel was according to standard algorithm. All clinical characteristic factors were collected and complication rate and incidence were further analyzed.Compared with our clinical experience in 2006, procedure-related complication rate declined from 1.09% to 0.4%, whereas the late complication rate decreased from 19.97% to 3.55%. No more pneumothorax, hematoma, catheter kinking, fractures, and pocket erosion were identified after using the standard algorithm. In alive oncology patients, 98% implanted port could serve a functional vascular access to fit therapeutic needs.This standard algorithm for choosing the best entry vessel is a simple guideline that is easy to follow. The algorithm has excellent efficiency and can minimize complication rates and incidence.

Common and uncommon complications of totally implantable central venous ports: a pictorial essay

PURPOSE

The purpose of this study is to present the characteristic radiologic features of common and uncommon complications in totally implantable central venous ports.

MATERIAL AND METHODS

The authors reviewed 138 implantations of central venous ports in oncologic patients during an 18-month period and present the characteristic imaging features of the complications detected.

RESULTS

All chest ports were placed via the internal jugular vein using both fluoroscopic and ultrasound guidance. The technical success rate was 99.3% (137/138). All catheter or port-related complications were retrospectively assessed. Sixteen complications were detected during the follow-up period, and catheter removal was required in 10 patients.

CONCLUSIONS

Image-guided central venous port catheter implantation is a very safe procedure with a low rate of complications. The typical imaging features of common and uncommon complications are very helpful in establishing the correct diagnosis and thus tailoring the appropriate therapy.

Should a Double-Lumen Catheter be withdrawn?

Haemodialysis needs a credible and recurrent access to the systemic circulation which can be accomplished by way of central vein catheterization. We report the case of bleeding after withdrawal of the double lumen catheter. A 36-year-old woman who was a known case of end-stage renal disease referred to a dialysis center because of her arteriovenous fistula malfunction. A double-lumen catheter was inserted via the right internal jugular vein but failed to become functional so in the emergency department we decided to withdrawal catheter under cardiac monitoring and pulse oximetry but unfortunately A few minutes after the withdrawal of the double lumen Catheter the patient became agitated and confused. The resuscitation team after infusing IV fluid and blood decided to emergent thoracotomy. We control bleeding by direct pressure and repaired a rupture of the posterior aspect of the right internal jugular and right subclavian vein junction. Six hours later she became alert and one week after discharged, she was in well general condition.
