The objective of this study was to investigate the feasibility of external jugular vein catheterization through an ear vein in piglets. Forty-six sevoflurane-midazolam anaesthetized piglets were included. External jugular vein catheterization was conducted through the ear vein using the Seldinger technique. Part 1 ( = 27): optimal puncture site was based on the deltoid tuberosity as a landmark to reach the external jugular vein. The final position of the catheter was verified in 25 piglets using computer tomography. Catheterization time was recorded and patency of the catheter assessed by repeated blood sampling for up to 4 h. Part 2 ( = 19): ear vein catheterization was without taking into account any landmarks. Functionality for blood sampling was evaluated as described in part 1. Catheter advancement was possible in 25/27 and 18/19 piglets in parts 1 and 2, respectively. Median (range) time required for successful catheterization was 1.95 (1-10) min ( = 38). The deltoid tuberosity was a good landmark to reach the external jugular vein. But blood sampling was also possible through catheters ending slightly cranial to the external jugular vein. Despite successful catheter advancement, blood sampling was not possible from one catheter in each part of the study (total: two piglets). One of these catheters presented luminal damage, while the other one presented as normal after being removed from the animal. Summarizing, central vein catheterization through the ear vein was feasible in 93.5% and repeated blood sampling was possible in 89.1% of the piglets ( = 46).

Review
Lemierre's syndrome is a rare, life-threatening complication of an acute oropharyngeal infection. It is generally characterised by pharyngitis secondary to , causing thrombophlebitis of the internal jugular vein and sepsis, with subsequent formation of septic emboli that can rapidly spread to different organ sites. The condition is associated with high mortality if treatment with antibiotics is delayed, and recent evidence suggests that patients are at significant risk of in-hospital morbidity and long-term neurological sequelae. Although it is agreed that antibiotics are the mainstay of treatment, there is currently no consensus on the use of anticoagulation in the condition. This review article aims to summarise our current understanding of Lemierre's syndrome with regard to its definition, epidemiology, microbiology, presentation, diagnosis, and treatment.

Review
OBJECTIVES
Internal jugular vein phlebectasia (IJVP) is a rare type of vascular abnormality that causes dilatation of internal jugular vein in the neck. There is presently no consensus on the most effective method of treatment for this condition, that is commonly seen in children. We conducted a systematic review of the literature reported till date to comprehend the key features of IJVP and its most effective therapeutic modalities.
METHODS
Five databases were searched until October 10, 2022 for articles of any design (including case reports) reporting IJVP in pediatric subjects. Individual patient data on demographics, clinical features of this entity and the differential diagnosis, methods of imaging, management, and outcome of illness were recorded. The quality assessment was performed using the Joanna Briggs Institute's Critical Appraisal Checklist for studies.
RESULTS
A total of 51 articles including 169 cases were retrieved and included in the analysis. Of the 169 patients, most of them were male children, and in 77% of cases right internal Juglar vein was involved. All patients had some symptoms suggestive of IJVP with most common ones being neck swelling or tenderness, and difficulty in breathing. In 90% of cases, it was observed that the neck swelling typically increases in size with Valsalva maneuver. Once jugular vein phlebectasia was clinically suspected, ultrasonography, CECT, or color Doppler flow imaging were used to confirm the diagnosis. The management of most of the cases was either conservative or surgical, and in surgery mostly ligation was performed. There have not been any cases of serious complications, therefore, according to included studies, a conservative approach is recommended with continuous monitoring. Out of the 51 studies included, most of them had low risk of bias.
CONCLUSION
Internal jugular vein phlebectasia, a rare benign condition, is most commonly found in children, and affects predominantly the right internal jugular vein. Although most patients did well with merely conservative treatment, still management of this vascular anomaly has to be on a case-by-case basis.

OBJECTIVES
The internal jugular vein (IJV) provides critical drainage from the brain, skull, and deep regions of the face and neck. Compromise to the bilateral IJVs has severe sequelae, but even unilateral IJV sacrifice or thrombosis after treatment can have sequelae. Despite the potential role of IJV reconstruction for head and neck surgeons, information about the indications, technique, and outcomes of the procedure are sparse.
PATIENTS AND METHODS
We present a woman who had IJV sacrifice for an oral cavity cancer along with a contralateral selective neck dissection and adjuvant chemoradiation who developed occlusion of the contralateral IJV after her treatment, resulting in unacceptable cervical lymphedema and extensive neck varicosities. An end-to-side bypass from the superior IJV to the ipsilateral external jugular vein was performed.
RESULTS
There were no complications from the procedure, which resulted in dissipation of her preoperative symptoms. We describe the literature surrounding IJV reconstruction, considerations for its use, the technique itself, and advice for perioperative management.
CONCLUSION
IJV reconstruction is a valuable but underutilized technique for the head and neck microvascular surgeon in cases of bilateral threatened IJV outflow.
