A case of right aortic arch type II combined with Kommerell's diverticulum and left innominate vein beneath the aortic arch.

The combination of the right aortic arch and aberrant left subclavian artery (ALSA) with Kommerell's diverticulum (KD) is rare to coexist with the left innominate vein (LINV) beneath the aortic arch. It escalates the surgical risk undoubtedly and increases the difficulty of clinical procedures. We report one case diagnosed by Ultrasound and Computed Tomography Angiography (CTA).

Surgical removal of a foreshortened right innominate vein Wallstent causing venous outflow obstruction.

OBJECTIVES: Stenting of central venous stenosis to preserve upper extremity hemodialysis access is well-described, though upper extremity complications secondary to these stents are less frequently discussed. METHODS: We present the case of a 43-year-old male with a right brachiocephalic fistula who developed symptoms of venous hypertension following placement of a Wallstent for central venous stenosis. Workup demonstrated venous outflow obstruction secondary to stent foreshortening into the right subclavian vein. RESULTS: The Wallstent was removed in a piecemeal fashion using an open surgical technique and a HeRO graft was placed for dedicated fistula outflow with complete relief of the patient's symptoms. CONCLUSION: In situations where a stent has migrated and endovascular removal is not possible, individual Wallstent fibers can be removed through a limited venotomy.

Prenatal ultrasound diagnosis of fetal isolated left innominate vein under the aortic arch: A case report.

Abnormalities of the left innominate vein beneath the aortic arch are exceedingly rare. While they may not exhibit overt clinical symptoms, misdiagnosis, or failure to diagnose can significantly complicate and increase the risk associated with cardiac interventional procedures.

Circumaortic double left innominate vein: a rare echocardiographic diagnosis confirmed during congenital heart surgery.

We report a case of a newborn infant with coarctation of the aorta and hypoplastic transverse aortic arch who was found to have a circumaortic double left innominate vein on echocardiography. This exceedingly rare finding was important for surgical planning and was confirmed during congenital heart surgery.

An unusual case of tetralogy of Fallot with an absent pulmonary valve associated with a retro-aortic innominate vein in a patient with a 16p12.2 microdeletion.

16p12.2 microdeletion has been associated with congenital heart defects and developmental delay. In this case, we describe the rare association between tetralogy of Fallot with an absent pulmonary valve a right-sided aortic arch and a retro-aortic innominate vein associated with a 16p12.2 microdeletion and epilepsy.

Modified bi-caval view-An ideal view for diagnosing left superior vena cava with large left innominate vein on saline contrast echocardiography.

Left superior vena cava (LSVC) is the most common congenital thoracic venous anomaly which commonly drains into the right atrium via the coronary sinus. Various clinical implications are associated with LSVC and is commonly diagnosed with saline contrast echocardiography. In this case we discuss the importance of a modified bi-caval view over the mid-oesophageal four-chamber view in diagnosing LSVC with the large left innominate vein.

Autologous pericardium used for reconstruction of left innominate vein in patient with mediastinal venous aneurysm:a case report.

BACKGROUND: Mediastinal venous aneurysm is a very rare disease and can be easily misdiagnosed. Patients are often asymptomatic while venous aneurysm of large size with adjacent structures oppressed can lead to discomfort. The surgical treatment for aneurysm of large vessels is often complex and challenging. CASE PRESENTATION: We reported a 52-year-old man with mediastinal mass who received operation on July 2019 in our hospital. Left innominate vein aneurysm was diagnosed during operation with superior vena cava involved. The aneurysm was resected and pericardium was taken to repair part wall of superior vena cava and reconstruct left innominate vein. The patient's postoperative course was uneventful. CONCLUSIONS: Venous aneurysm should be considered when mediastinal mass has no clear boundary with large veins or even seems to connect with them. Magnetic resonance imaging, computed tomographic angiography and invasive venography can be performed to further evaluate the mass once diagnosis of venous aneurysm was suspected. Using pericardium to repair large veins is a good choice which is safe and costless.

Congenital arteriovenous fistula between descending aorta and the left innominate vein.

Thoracic aortocaval fistulae are rare entities where a direct shunt between thoracic arteries and systemic veins is seen. They can be traumatic or congenital in origin. Congenital thoracic aortocaval fistulae usually involve descending aorta and azygos, hemiazygos systems. Presenting symptoms range from continuous murmur to signs of congestive heart failure. In this case report, imaging findings of a 3-year-old girl referred for continuous murmur over the left sternal border are presented. Computed tomography angiography revealed multiple tortuous vessels along the descending aorta with a course toward the left brachiocephalic vein, and was suspicious for an aorta-venous fistula. Subsequent digital subtraction angiography for treatment planning showed a fistula originating at the level of the left 6th intercostal artery, with direct drainage into the left brachiocephalic vein without involvement of the azygos/hemiazygos system.

Ultrasound-guided totally implantable venous access ports via the right innominate vein: a new approach for patients with breast cancer.

BACKGROUND: To evaluate the feasibility and safety of ultrasound-guided totally implantable venous access port (TIVAP) implantation via the right innominate vein in patients with breast cancer. METHODS: Sixty-seven breast cancer patients underwent ultrasound-guided implantation of TIVAPs via the right innominate vein for administration of chemotherapy. Clinical data including technical success, success rate for the first attempt, periprocedural, and postoperative complications were recorded and retrospectively studied. RESULTS: All patients underwent successful surgery. The success rate of the first attempt was 95.52% (64/67). The operation time was 28 to 45 min, with an average of 36 ± 6 min. Periprocedural complications included artery punctures in 1 (1.50%, 1/67) patient. Prior to this study, the mean TIVAP time was 257 ± 3 days (range 41 to 705 days). The rate of postoperative complications was 4.48% (3/67), including catheter-related infections in 1 case and fibrin sheath formation in 2 cases. Up to the present study, three people had unplanned port withdrawal due to complications, and the TIVAPs for 25 patients were still in normal use. CONCLUSIONS: The success rate of ultrasound-guided TIVAPs via the right innominate vein is high with low complications, thus safe and feasible. This technique can provide a new option for chemotherapy of breast cancer patients.

Retroaortic innominate vein in a patient with transposition of the great arteries: the surgical implications.

We describe the case of a newborn infant with transposition of the great vessels and a retroaortic innominate vein. This is a previously undescribed association. The decision was made to incorporate the retroaortic innominate vein into the Lecompte procedure at the time of surgery to avoid the risk of superior caval vein syndrome.

Isolated retroaortic innominate vein and right aortic arch: a case report and review of literature.

Retroaortic course of left innominate vein is a rare venous anomaly which is usually associated with CHD. Isolated retroaortic innominate vein is exceedingly rare with only a handful of reported cases. We report an otherwise healthy newborn with isolated retroaortic innominate vein and right aortic arch, a combination which has previously not been reported.

Comparison between ultrasound-guided TIVAD via the right innominate vein and the right internal jugular vein approach.

BACKGROUND: To compare the efficacy and safety of right internal jugular vein (IJV) approach and right innominate vein (INV) approach for US-guided totally implantable venous access devices (TIVADs), and to explore the advantages and disadvantages of the two approaches. METHODS: Six hundred and nineteen adult patients had long-term infusion and chemotherapy needs and inconvenience of peripheral venous infusion. Right INV approach was used to implant 339 cases of TIVADs, and right IJV approach was used to implant 280 cases of TIVADs. The success rate of one-time catheterization and the incidence of complications in the two groups were retrospectively analyzed. RESULTS: All patients were successfully implanted in TIVAD. The success rates of one-time puncture in INV group and IJV approach group were 98.53% (334/339) and 95.36% (267/280), respectively. There was significant difference between the two groups (P = 0.020). The incidence of perioperative complications and long-term complications in the right INV group were 1.18% (4/339) and 3.54% (12/339), respectively, while those in the right IJV group were 1.43% (4280) and 3.93% (11280). There was no significant difference in the incidence of perioperative or long-term complications between the two groups (P = 0.785, P = 0.799, respectively). CONCLUSIONS: US-guided TIVADs via the right INV approach and the right IJV approach are both safe and reliable. The right INV approach improves the one-time puncture success rate, as long as the technique is properly operated, serious complications rarely occur.

Large left innominate vein aneurysm presenting as an anterior mediastinal tumour in a young female.

We report a rare case of large innominate vein aneurysm in a young women clinically presenting with persistent dry cough and retrosternal pressure. Chest X-ray showed a mediastinal widening leading to thoracic computed tomography, MRI, and phlebography. Initial conservative treatment with regular follow-up was performed. Upon aneurysm growth and recurrent pulmonary infection we decided to surgically resect the aneurysm via a minimally invasive approach.

A Rare Experience of Infective Residual Sheath in the Wall of the Innominate Vein after Extraction of Implantable-Defibrillators.

BACKGROUND: Cardiac device-related infective endocarditis is an uncommon but potentially fatal complication. Therefore, cardiac devices should be removed as soon as a device-related infection is suspected. CASE REPORT: A 56-year-old male with a history of arrhythmogenic right ventricular dysplasia with implantable cardioverter-defibrillators (ICDs) 7 years earlier and re-implantation of ICDs due to dysfunction 18 months ago presented with erosion of the ICD pocket with Pseudomonas bacteremia. For the past year, only multiple wound debridements were performed. Accordingly, we performed debridement and removal of the generator during this admission; however, bacteremia still persisted. Using transesophageal echocardiography, we detected vegetation on the pacing leads and tricuspid valve in the right atrium. We performed thoracotomy with tricuspid valve repair and pacing wire removal. However, anterior chest pain and refractory bacteremia occurred 3 months later after discharge, and an infectious foreign body in the wall of the innominate vein was detected using chest computer tomography. Thoracotomy was again performed for resection of the innominate vein with the infection source. Postoperative recovery was good, with no systemic infection or bacteremia. CONCLUSIONS: Pacing lead extraction is a common procedure following cardiac rhythm management device-related infection. However, residual foreign body-related bacteremia should be suspected in cases with fever of unknown origin after primary surgery. Preserving the innominate vein with patch repair is a feasible option. However, a postoperative 4-week course of antibiotics is recommended.

Cardiac resynchronization therapy in a patient with persistent left superior vena cava draining into the coronary sinus and absent innominate vein: a case report and review of literature.

INTRODUCTION: Persistent left superior vena cava (PLSVC) is a rare congenital anomaly of the superior venous system that may be discovered at the time of cardiac implantable electronic device (CIED) implantation. METHODS AND RESULTS: We present a subject who needed cardiac resynchronization therapy (CRT)-CIED implantation and was discovered to have PLSVC with absent innominate vein during the implant procedure. We were able to successfully implant a CRT-CIED using a right-sided approach via the right superior vena cava (SVC). We present a description of our implant technique and a brief review of the different aspects of CIED implantation in subjects with variants of PLSVC. CONCLUSION: Superior venous anomalies such as PLSVC can make CIED implantation technically challenging. However, with increasing operator experience, cardiac imaging and appropriate tools successful CIED implantation is possible in almost all cases.

The jugular-subclavian junction and venous drainage of the brain.

Lung cancers and mediastinal masses can invade the veins in the upper mediastinum and neck. It can be challenging to determine management options and the feasibility of resection particularly when tumors involve the major venous junctions. Furthermore, impaired flow in these veins can have devastating complications such as Paget-Schroetter syndrome, which describes a constellation of symptoms (arm swelling, cyanosis, pain) due to stenosis of the subclavian vein. This section will provide an overview of venous drainage of the brain, which can be divided into two major systems-superficial medullary venous system and deep medullary venous system. The anatomy and function of the great veins of the neck and upper mediastinum, including the internal jugular vein, subclavian vein, and brachiocephalic (i.e., innominate) vein will be described. Also discussed will be principles of ligation of the venous structures and the importance of keeping the venous junctions intact to facilitate and maximize the development of collateral flow. This section will also discuss ensuing complications when blood flow is impaired, such as development of upper extremity deep venous thrombosis and cerebral venous thrombosis (CVT). CVT can result in a stroke and is an umbrella term that refers to problems in cerebral venous outflow due to numerous etiologies.

A case of thoracic central venous obstruction treated by the innominate-to-right-atrial bypass grafting technique under extracorporeal circulation.

A 46-year-old woman with stage 5 chronic kidney disease was unable to undergo hemodialysis treatment due to thoracic central venous obstruction (TCVO) and blockage of the tunneled cuffed catheter. This patient also presented with symptoms of TCVO. When percutaneous procedure was not possible, we resolved the obstruction with the innominate-to-right-atrial bypass grafting technique under extracorporeal circulation. There are few reports on this surgical approach. In terms of patient prognosis, this may be an effective solution to this problem.

Successful management of fatal cardiac tamponade resulting from intravascular intervention for central vein occlusion in hemodialysis patients: A case report.

This case report highlights the successful management of fatal cardiac tamponade caused by intravascular intervention for central vein occlusion in hemodialysis patients. Prompt diagnosis and treatment are essential for patient prognosis in such cases. We present a case involving a challenging surgical procedure to address multiple complications, emphasizing the importance of early detection and appropriate interventions. The patient, who had a history of long-term central venous catheter use for hemodialysis, was diagnosed with central vein stenosis in addition to superior vena cava occlusion, hemodialysis catheter rupture, hypertension, and end-stage renal disease. Urgent ultrasound examination during surgery revealed pericardial effusion, prompting immediate pericardial drainage for stabilization. To overcome the complex challenges, we successfully performed an innominate vein-right atrial appendage bypass to restore vascular access and salvage the patient's life. The timely use of echocardiography for diagnosis and pericardial drainage contributed to stabilizing the patient's vital signs, providing an opportunity for subsequent surgical intervention. The innominate vein-right atrial appendage bypass procedure successfully relieved central vein stenosis and saved the patient's life. Although this surgical technique is not widely documented in hemodialysis patients with central venous involvement, it show cases the potential benefits for clinicians managing vascular access in this patient population. This case report underscores the need for awareness among clinicians regarding the risk of cardiac tamponade associated with intravascular intervention for central vein stenosis in hemodialysis patients. Minimizing central venous catheterization and prioritizing autogenous arteriovenous fistulas are crucial principles in preparing vascular access for hemodialysis patients. Early detection, timely interventions, and consideration of alternative surgical techniques can improve outcomes and prevent life-threatening complications.

Stenting of innominate vein compression syndrome.

We report the case of a 60-year-old woman who sought medical attention for left cervical and supraclavicular pain and swelling. Previous computed tomography, intravascular ultrasound, and venography studies were reviewed, confirming extrinsic compression of the left innominate vein by the left common carotid artery against the left clavicle head. Stenting of the lesion was performed, with good mid-term symptom relief and patency. It is, to the best of our knowledge, the first case study in the literature to report endovascular treatment of this syndrome.
