Thoracoscopic and Transmanubrial Approach for Mediastinal Tumor Extending to the Neck

Annals of Thoracic Surgery Short Reports (2023)

Shohei Mori Makoto Odaka Maki Oh Rintaro Shigemori Naoki Toya

The combination of thoracoscopic and transmanubrial approaches provides good visualization and maneuverability of the cervicothoracic junction area. Here we report the case of a young woman with a mediastinal tumor extending to the neck who first underwent a thoracoscopic approach followed by a transmanubrial approach. This procedure was superior in terms of technical advantages and preserved function as well as minimally invasive and cosmetically pleasing. The preceding thoracoscopic approach made it easier to understand the location relationships between the tumor and anatomic structures in the transmanubrial approach. This combined procedure is appropriate for mediastinal tumors extending to the neck.

Impact of Bifidobacterium adolescentis in patients with abdominal aortic aneurysm: a cross-sectional study

Bioscience of Microbiota Food and Health (2022)

Eisaku Ito Takao Ohki Naoki Toya Hikaru Nakagawa Ayako Horigome

The relationships between various diseases and the human gut microbiota (GM) have been revealed. However, the relationships between the human abdominal aortic aneurysm (AAA) and GM remains unknown. The aim of this cross-sectional study was to clarify the association between the human AAA and GM. Stool samples from 30 consecutive patients with AAA before aneurysm repair and those of 30 controls without vascular diseases were analyzed by 16S rRNA gene (V3-4) sequencing using an Illumina MiSeq system and QIIME 2. There was no significant difference in age (75 vs. 75 years) or gender (80% vs. 87% males) between the groups. No significant difference in GM composition was observed in principal coordinate analysis between the two groups, whereas the AAA group showed a significantly lower abundance of Bifidobacterium adolescentis (p<0.01) at the species level than the controls. This study demonstrated that the abundance of B. adolescentis decreased in patients with AAA. This is the first study to show the characteristics of the GM in patients with AAA. Studies are needed to reveal if causal relationships exists between the human AAA and GM.

Fenestrated Thoracic Endovascular Repair for Acute Type B Aortic Dissection with Isolated Left Vertebral Artery: A Case Report

Annals of Vascular Diseases (2024)

Yuta Yamada Takao Ohki Naoki Toya Eisaku Ito Hikaru Nakagawa

Thoracic endovascular aortic repair (TEVAR) of acute uncomplicated type B aortic dissection (uTBAD) has been discussed for its potential to prevent future aortic events. We present a fenestrated TEVAR in the case of an 86-year-old man with acute uTBAD with an isolated left vertebral artery (ILVA). The ILVA originated from the distal side of the left subclavian artery, the left subclavian artery, and the intramural hematoma with an ulcer-like projection extended close to the left subclavian artery. We selected a fenestrated stent graft to achieve a proximal healthy landing. This case demonstrates that a fenestrated stent graft for acute uTBAD is useful for preserving arch vessels.

A case of multiple aneurysms in the celiac artery region with idiopathic portal hypertension.

特発性門脈圧亢進症 (IPH) 患者に合併した腹腔動脈領域の未破裂の多発動脈瘤に対し手術を施行した.症例は飲酒歴がなく肝炎ウイルスマーカー陰性の49歳,女性.腹部膨満を主訴に近医を受診し,肝硬変,食道静脈瘤および脾機能亢進症と診断され,当院へ転院した.総肝動脈起始部付近に径約3cm, 脾動脈に径約2cmをはじめ多発する動脈瘤を認めた. Hassab手術および総肝動脈瘤切除を施行した.術前の血管造影で膵十二指腸動脈のアーケードを介し肝内動脈血流が造影されたこと,瘤切除後も固有肝動脈の拍動が良好であったことより,総肝動脈の血行再建は不要と判断した.病理学的には肝の基本構造は保たれており, IPHと診断された.総肝動脈瘤の内膜の粥状硬化は皆無であり,内圧上昇に伴い発生したものと考えられた.

Polyester Grafts Are a Risk Factor for Postimplantation Syndrome after Abdominal Endovascular Aneurysm Repair: Retrospective Analysis for Polyester Graft, Excluder®, and Endologix Powerlink®/AFX®

Annals of Vascular Diseases (2018)

Eisaku Ito Naoki Toya Soichiro Fukushima Ryosuke Nishie Tadashi Akiba

Objective: Postimplantation syndrome (PIS) is a postoperative syndrome that occurs after endovascular aneurysm repair (EVAR), accompanied by high fever, leukocytosis, and high serum C-reactive protein (CRP). Its pathogenesis and clinical meaning are still under discussion. Here, we evaluate the relationship between postoperative fever after EVAR and graft fabric focusing on Endologix Powerlink® and AFX® (EPL/AFX).

Surgical Treatment of a Giant Right Hepatic Artery Aneurysm with an Aberrant Left Hepatic Artery: Report of a Case

Annals of Vascular Diseases (2015)

Kota Shukuzawa Naoki Toya Soichiro Fukushima Masamichi Momose Tadashi Akiba

Hepatic artery aneurysms are rare. We describe a case of a successful surgical treatment of a giant hepatic aneurysm without revascularization. A 63-year-old female was admitted to our department complaining of abdominal pain. Computed tomography showed a thrombosed hepatic artery aneurysm measuring 5.5 cm in diameter. A celiac angiography revealed an aberrant left hepatic artery and a right hepatic aneurysm. Liver blood flow and the right hepatic aneurysm were visualized via collateral pathway from the aberrant left hepatic artery. We performed an aneurysmorrhaphy without revascularization. Postoperative course was uneventful and the patient is doing well 3 months after surgery.

[Treatment of an iliac artery pseudoaneurysm managed with a stent graft].

PubMed (1999)

Yudo Ishii Hideo Hagiwara Naoki Toya Hiromasa Tachihara Yuichiro Yamazaki

Recent developments have extended the indications for endovascular intervention to include endovascular lesions, such as aneurysms and sclerotic arterioocclusive disease. Although conventional treatment of pseudoaneurysms is mainly surgical intervention, the development of stent grafts has made this treatment less invasive than previously. We placed a stent graft in a pseudoaneurysm of the iliac artery with good results, as described in this report. Treatment of a pseudoaneurysm with a stent graft avoids the risk associated with general anesthesia and reduces surgical invasiveness, similar to laparotomy. We expect that this therapeutic mode will be developed further in the future.

New Proposal Strategy of Sentinel Lymph Node Navigation Surgery for Endoscopic Curability C-2: A Retrospective Study

Anticancer Research (2024)

Naoto Takahashi Muneharu Fujisaki Yuta Takano Kenji Takeshita Naoki Toya

Background/Aim: The purpose of this study was to evaluate the outcomes of the sentinel node navigation surgery (SNNS) followed by limited gastrectomy for early gastric cancer (EGC) with Endoscopic Curability C-2 (eCuraC-2). Patients and Methods: Between 2001 and 2018, 33 patients were included in this study. Following sentinel node (SN) biopsy using indocyanine green combined with an infrared ray laparoscopic system, limited gastrectomy (LG) [wedge resection (WR), or segmental gastrectomy (SG)] was performed without extended lymphadenectomy. Results: SN detection rate was 97% (32/33). The mean number of SNs per case was 7.8. Three patients (9.1%) with lymph node metastasis (LNM) had a positive SN identified by intraoperative pathological examination. When intraoperative pathologic examination showed SN to be LNM negative, 11 patients underwent WR, and seven were subjected to SG. Postoperative pathological examinations showed no false negatives for LNM, and four patients (12%) had residual cancer in their resected stomachs. Overall survival and disease-specific survival five years after SNNS were 87.9% and 100%, respectively. Conclusion: SNNS followed by LG with lymphatic basin resection may be one of the ideal procedures for patients with eCuraC-2 due to the accurate diagnosis of LNM and favorable disease-specific prognosis.
