Right subclavian artery injury during catheter insertion into the right internal jugular vein treated with endovascular stent graft placement after balloon occlusion test: A case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Subclavian artery injuries during internal jugular vein puncture when attempting central venous catheter insertion are rare. A 60-year-old man undergoing treatment for neuromyelitis optica with paralysis and sensory loss developed a complication during catheter placement into his right internal jugular vein for plasmapheresis. His previous physician felt resistance and discontinued the procedure. The patient later developed mild dyspnea and dysphagia. Computed tomography scans indicated thrombus formation and tracheal deviation. Contrast-enhanced computed tomography scans showed right subclavian artery injury with extravasation and a large pseudoaneurysm. Following transferal to our hospital, he was stable and asymptomatic; however, contrast-enhanced computed tomography scans showed a pseudoaneurysm located proximal to the right subclavian artery. Considering challenges with compression hemostasis and the invasiveness of open surgery, endovascular treatment was selected using a VIABAHN stent graft. A balloon occlusion test of the right vertebral artery was performed to assess stroke risk. Prophylactic embolization of the right vertebral artery, internal thoracic artery, and thyrocervical trunk were performed to prevent a type 2 endoleak. On hospital day 5, our patient showed no postoperative complications and was transferred to the referring hospital. Follow-up imaging showed the graft was intact with no pseudoaneurysm, confirming successful treatment. Endovascular treatment with a stent graft is highly effective for peripheral artery injuries. Using a balloon occlusion test to assess collateral blood flow and stroke risk is essential pretreatment, especially when a graft might occlude the vertebral artery. Balloon occlusion tests are recommended when planning treatment for iatrogenic and other types of subclavian artery injuries.
