An ultrasound-guided supraclavicular approach for tunneled central venous catheter insertion can be safely performed by junior residents.

PURPOSE: Ultrasound-guided supraclavicular catheterization (UGSC) of the brachiocephalic vein (BCV) for long-term tunneled central venous catheter (tCVC) insertion may be safer than the internal jugular vein approach due to its superior field of view. We examined the clinical outcomes of tCVC insertions performed by junior residents through UGSC of the BCV. PATIENTS AND METHODS: From January 2018 to December 2023, we assessed clinical outcomes and compared the experience levels of surgeons conducting tCVC insertions. Surgeons were categorized into three groups: junior residency (JR), senior residency (SR), and board-certified pediatric surgeons (BCPS). RESULTS: 177 tCVC insertions were done on 146 patients. Intraoperative complications included 6 cases of arterial puncture, 1 case of pneumothorax, 1 case of over insertion of catheter tip, and 1 case of suspected hemothorax. Distribution across groups was as follows: 28 cases (15.8%) in JR group, 92 (52.0%) in SR group, and 57 (32.2%) in BCPS group. Although the JR group exhibited longer operation times than the BCPS group, no significant differences in intraoperative complications were noted. CONCLUSION: Junior residents can safely perform UGSC for tCVC insertion. However, careful consideration of complications such as arterial or thoracic puncture is essential and case selection should be based on experience.

An unusual case of duplicated left brachiocephalic vein with right sided aortic arch and aberrant origin of LSCA in a patient undergoing implantable cardioverter defibrillator (ICD) implantation.

BACKGROUND: Anomalous left brachiocephalic vein (ALBCV) is a rare venous anomaly. Double Left brachiocephalic vein is the rarest type of ALBCV anomaly. CASE REPORT: Here we report a case of gentleman with post myocardial infarction ventricular tachycardia who underwent ICD implantation, where we could not place the lead initially through left side. CT angiography revealed presence of a duplicated circumaortic left BCV. It's cranial limb coursing normally anterior to arch and compressed at its confluence with RBCV and the caudal limb with a subaortic course draining into the RSVC. We report this first case of double LBCV along with right sided aortic arch and aberrant origin of LSCA arising from Kommerel's diverticulum. CONCLUSION: This case highlights that interventional cardiologists should be aware of these venous anomalies for proper planning and implantation of CIED successfully via transvenous approach.

Resection and a rare type of reconstruction of the superior vena cava with the left brachiocephalic vein.

Resection and reconstruction of the superior vena cava (SVC) are required in a selected group of patients with anterior mediastinal tumors and lung neoplasms. We present the case of a 63-year-old woman who underwent invasive type B2 thymoma resection and a rare type of reconstruction of the superior vena cava using a patch of the left brachiocephalic vein (LBV). The various types of reconstruction of the superior vena cava are discussed.

Clinical outcome of percutaneous angioplasty and covered stent placement for treatment of left brachiocephalic vein obstruction in hemodialysis patients.

BACKGROUND: Left brachiocephalic vein (LBV) obstruction is a common complication in patients undergoing hemodialysis. This study aimed to compare the clinical characteristics and outcomes of patients with LBV obstruction who underwent percutaneous angioplasty or stenting. METHODS: We performed a retrospective study of 67 hemodialysis patients with LBV stenosis or occlusion who underwent percutaneous transluminal angioplasty (PTA; n = 25) or percutaneous transluminal stenting (PTS; n = 42). We compared the clinical characteristics, lesion features, and patency between the two groups of patients. RESULTS: The average age, sex, smoking history, body mass index, obstruction period, comorbidities, and clinical manifestations were comparable between the PTA and PTS groups. Prior ipsilateral catheterization was less common in the PTS group than in the PTA group (14.3% vs 36.0%, p < 0.05). Smaller sized balloons were used in the PTS group than in the PTA group (p < 0.05). The overall primary patency rates were similar between the two groups, whereas the secondary patency rate in the PTS group was higher than that in the PTA group (p < 0.05). The average age, sex, smoking history, body mass index, obstruction period, prior ipsilateral catheterization, comorbidities, and types of lesions were comparable between patients with or without restenosis, while patients with restenosis had a higher percentage of high venous pressure than those without restenosis (87.5% vs 60.5%, p < 0.05). CONCLUSION: The primary patency rates were similar in the angioplasty and the stenting groups. Stenting has a significantly higher secondary patency rate than angioplasty alone for treating LBV obstruction and is required more commonly in patients without prior ipsilateral catheterization.

Innominate Vein Thrombosis: A Case Report and Literature Review.

The brachiocephalic vein (BCV), also known as the innominate vein, is a central vein in the upper chest formed by merging the internal jugular and subclavian veins. It plays a crucial role in venous return from the head, neck, and upper extremities and is significant in procedures such as pacemaker and implantable cardioverter-defibrillator (ICD) placement, chemotherapy ports, and central venous catheter insertions. The presence of foreign bodies and local malignancy are major risk factors for thrombosis in the BCV. As part of the deep venous system, BCV thrombosis (BCVT) is a rare condition but can lead to serious complications like superior vena cava syndrome and, rarely, pulmonary embolism. This case report presents an 82-year-old woman with a history of heart failure with reduced ejection fraction, coronary artery disease, atrial fibrillation, HIV, pulmonary embolism, systemic lupus erythematosus, and breast cancer who required an ICD placement due to persistent systolic dysfunction. During the procedure, chronic BCVT leading to the stenosis was incidentally discovered, necessitating urgent vascular intervention to establish venous patency. The patient's complex medical history, including previous chemotherapy through a central venous catheter, contributed to the risk factors for BCVT. The multidisciplinary approach led to successful ICD placement and the reinstatement of anticoagulation therapy. This case underscores the rarity and severity of BCVT and highlights the importance of pre-procedural imaging, such as CT venography, in patients with multiple risk factors. Additionally, the report suggests considering leadless ICD technology for patients with limited venous access to avoid complications. The findings emphasize the critical need for thorough evaluation and planning in complex cases to ensure successful outcomes.

The placement of totally implantable venous access port via right brachiocephalic vein access: its clinical application / 介入放射学杂志

Objective To evaluate the feasibility and safety of embedding the totally implantable venous access port (TIVAP) via the access of right brachiocephalic vein (BCV).Methods The clinical data of 493 patients,who underwent the placement of TIVAP by using right BCV route during the period from March 2013 to December 2015,were retrospectively analyzed.The patients included 137 males and 356 females,with a mean age of (47.3±13.2) years old (ranging from 29 to 78 years old).The puncture success rate and TIVAP indwelling procedure-related complications were analyzed.Results The technical success rate was 100％,the success rate of initial puncturing was 99％ (488/493).The mean operation time was (22.5± 8.3) minutes (range of 18-35 minutes).Mis-puncturing of artery happened in 3 patients (0.61％,3/493);and no severe complications such as hemothorax or pneumothorax occurred.After implantation,the patients carried TIVAP for 124-986 days,with a mean of (271.1±53.8) days.The incidence of complications was 2.25％ (11/488),including hemorrhage at port site (n=2),catheter-related infection (n=l),partial thrombosis (n=2),and formation of fibrous protein sheath (n=6).No serious complications such as displacement or rupture of catheter,or catheter pinch-off syndrome (POS),etc.were observed.Conclusion The implantation of TIVAP by using right BCV route has high puncturing success rate,the technique is safe and reliable,and it can provide another option of catheter access for the clinical performance of TIVAP implantation.

An Unusual Cause of Left Brachiocephalic Vein Occlusion: Extrinsic Compression by the Aortic Arch in a Hemodialysis Patient / 대한내과학회지

The most common cause of central venous obstruction including left braciocephalic vein is intrinsic stenosis associated with a previous central venous catheter or other devices. Occasionally, patients with no history of central venous catheterization present with left brachiocephalic vein occlusion. This occurs as a result of extrinsic compression of the brachiocephalic vein by adjacent vascular structures, especially the aortic arch and its branches. Here, we report a case of left brachiocephalic vein compression caused by a tortuous, ectatic aortic arch in a patient with no history of central vein catheterization. To our knowledge, this is the first report of extrinsic compression of the brachiocephalic vein by the aortic arch in Korea.

Stent implantation can relieve the obstruction immediately and the technique is safe and effective. This paper aims to summarize the current situation and the clinical practice of this therapy, to evaluate its effectiveness and to make a prospect of the developing trends and the problems need to be solved urgently.

An unusual termination of seven veins in the jugulo-subclavian junction / Inusual terminación de siete venas en la unión yugulo-subclavia

During anatomical dissection of a female Caucasian cadaver in our department, we observed an unusual termination of seven veins at the jugulo-subclavian junction. Normally, the jugulo-subclavian junction is formed by the union of the internal jugular vein and the subclavian vein, and gives rise to the brachionocephalic vein. In our case, except from these two, five additional veins, namely the cephalic vein, the transverse cervical vein, the external jugular vein, the anterior jugular vein, and the vertebral vein, were also joined at the level of the jugulo-subclavian junction, in order to form the brachionocephalic vein. Such a variation has not yet been reported in the literature.

Durante la disección anatómica de un cadáver caucásico femenino, se observó una inusual terminación de siete venas en el lugar de unión yúgulo-subclavia. Normalmente, la unión yúgulo-subclavia consiste en la unión de la vena yugular interna y la vena subclavia, que forman la vena braquiocefálica. En nuestro caso, además de estas dos venas, se observaron cinco venas adicionales, la vena cefálica, la vena cervical transversa, la vena yugular externa, la vena yugular anterior y la vena vertebral, la que también se unió en el nivel de la unión yúgulo-subclavia, a fin de formar la vena braquiocefálica. Tal variación no ha sido reportado en la literatura.

Anomalous sub aortic left brachiocephalic vein: a case report / Veia braquiocefálica esquerda subaórtica anômala: relato de caso

The left brachiocephalic vein occasionally follows an aberrant course. It is usually associated with congenital cardiac anomaly. We present a case of anomalous left brachiocephalic vein which followed a sub aortic course, with no cardiac abnormality. Multi detector computed tomography is very useful in accurate diagnosis of this condition and prevents any further investigation in cases of isolated abnormalities.

A veia braquiocefálica esquerda, ocasionalmente, segue curso aberrante. Esta variação freqüentemente está associada com anomalias congênitas do coração. Neste trabalho é apresentado um caso de veia braquiocefálica esquerda anômala, com trajeto subaórtico, sem anormalidade cardíaca. A tomografia computadorizada com multidetectores é muito útil no correto diagnóstico dessa condição e permite a conclusão diagnóstica, sem quaisquer outras investigações.

Two cases of self expandable stent implantation in patient with occlusive restenosis of brachiocephalic vein stent / 대한내과학회지

Percutaneous venous angioplasty and stent placement is a effective procedure in the treatment of central venous stenosis and occlusion. But multiple repeat interventions are occasionally required due to restenosis. Self expandable stent is preferred to balloon expandable stent in case of brachiocephalic vein stenting due to anatomic consideration and veinous characteristics. We reported two cases of successful recanalization using self expandable stent of the occlusive kinked in-stent restenosis of the previous balloon expandable stent at left brachiocephalic vein occlusion.

Role of the Inferior Thyroid Vein after Left Brachiocephalic Vein Division During Aortic Surgery / 대한흉부외과학회지

BACKGROUND: In aortic surgery, division and ligation of the left brachiocephalic vein(LBV) may improve exposure of the aortic arch but controversy continues about the safety of this division and whether a divided vein should be reanastomosed after arch replacement was completed. The safety of LBV division and the fate of the left subclavian venous drainage after LBV division were studied. MATERIAL AND METHOD: From November 1998 to January 2001, planned division and ligation of the LBV on the mid-line after median sternotomy was performed in 10 patients during the aortic surgery with the consideration of local anatomy and distal aortic anastomosis. Assessment for upper extremity edema and neurologic symptoms, measurement of venous pressure in the right atrium and left internal jugular vein, and digital subtraction venography(DSV) of the left arm were made postoperatively. RESULT: In 10 patients there was improvement in access to the aortic arch for procedures on the ascending aorta or aortic arch. The mean age of patients was 62 years(range 24 to 70). Follow-up ranged from 3 weeks to 13 months. One patient died because of mediastinitis from methicilline-resistant staphylococcus aureus strain. All patients had edema on the left upper extremity, but resolved by the postoperative day 4. No patient had any residual edema or difficulty in using the left upper extremity during the entire follow-up period. No patient had postoperative stroke. Pressure difference between the right atrium and left internal jugular vein was peaked on the immediate postoperative period(mean peak pressure difference = 25mmHg), but gradually decreased, then plated by the postoperative day 4. In all DSV studies left subclavian vein flowed across the midline through the inferior thyroid venous plexus. CONCLUSION: We conclude that division of LBV is safe and reanastomosis is not necessary if inferior thyroid vein, which is developed as a main bridge connecting the left subclavian vein with right venous system, is preserved.

Clinal anatomy and significance of anterior surgical approach to upper thoracic spine / 中华骨科杂志

Objective To investigate the anatomic relationship between the upper thoracic vertebrae and adjacent structures in anterior approach of upper thoracic spine, an anatomy study was conducted and its clinical significance was evaluated. Methods Twenty upper thoracic spine specimens of adult human cadaver were exposed, measured and studied for their anatomic landmarks. The origin, course of the recurrent laryngeal nerve, thoracic duct and blood vessels and their relationship were measured and analyzed. The advantages and disadvantages of different surgical approaches exposing the upper thoracic vertebrae were also evaluated and compared. Results The right recurrent laryngeal nerve reaches the tracheo-esophageal groove at the level of C6-7 disc in 55% of the specimens and derives from vagus nerve at the level of T1,2. The thoracic duct empties into the systemic venous system from T1 to T1-2 disc space in 75% of the specimens and among them, more than 50% up to T1 level. The left brachiocephalic vein is at T3 in 55% of the specimens; and the aortic arch is at T3-4 disc in 80% of the specimens. The anterior aspect of T3 can be easily exposed through a modified anterior approach to the upper thoracic vertebrae in only 45% of the specimens(9), compared with outside space of the brachiocephalic trunk(between the right brachiocephalic vein and the brachiocephalic trunk and left brachiocephalic vein) in 95% of the specimens (19). Conclusion Surgical approach through outside space of the brachiocephalic trunk is simple and adequate to expose the T3,4 vertebra body and can get more exposed space of 0.5-1 of the vertebra body than through inner space of the brachiocephalic trunk and can be utilized selectively during anterior upper thoracic spine surgery. Attention should be paid to avoid injury of vagus nerve in the middle, right recurrent laryngeal nerve on the right and thoracic duct on the left, respectively.
