For the modern practice of cancer surgery, the concept of oncovascular surgery (OVS), defined as cancer resection with concurrent ligation or reconstruction of a major vascular structure, can be very important. OVS for advanced cancers requires specialized procedures performed by a specialized multidisciplinary team. Roles of oncovascular surgeons are summarized as: a primary surgeon in vessel-origin tumors, a rescue surgeon treating complications during cancer surgery, and a consultant surgeon as a multidisciplinary team for cancer surgery. Vascular surgeons must show leadership in cancer surgery in cases of complex advanced diseases, such as angiosarcoma, leiomyosarcoma, intravenous leiomyomatosis, retroperitoneal soft tissue sarcoma, iatrogenic injury of the major vessels during cancer surgery, pancreatic cancer with vascular invasion, extremity soft tissue sarcoma, melanoma and others.

5.Ectopic Variceal Bleeding from the Hepaticojejunostomy due to Extrahepatic Portal Vein Occlusion: How to Treat?
Vascular Specialist International 2023;39(3):22-
Atypical variceal bleeding, which primarily stems from extrahepatic portal vein obstruction (EHPVO), is a severe complication of pancreatic hepatobiliary surgery. This review provides insights into this condition’s incidence, diagnosis, and management strategies. The treatment modalities for atypical variceal bleeding resulting from EHPVO range from endoscopic intervention to surgical procedures, including direct variceal ligation and shunt surgery. Here, we discuss the efficacy and potential limitations of each treatment approach. Additionally, we explored the utility and therapeutic advantages of the meso-Rex shunt, a particularly promising surgical technique for mitigating the hemodynamic and metabolic impacts of EHPVO.

PURPOSE: Sentinel lymph node biopsy (SLNB) is an accurate and effective means of axillary nodal staging in early breast cancer. However its indication after neoadjuvant chemotherapy (NAC) is under constant debate. The present study evaluates the reliability of SLNB in assessing axillary nodal status after NAC. METHODS: Data from 281 patients who had received NAC and subsequent SLNB were reviewed. The identification and false negative rates of SLNB were determined and the clinicopathologic factors associated with false negative results were investigated using univariate analysis. RESULTS: The identification rate of SLNB after NAC was 93.6% and the false negative rate was 10.4%. Hormone receptor status, especially progesterone receptor positivity, was significantly associated with false negative results. The accuracy of intraoperative frozen section examination of sentinel lymph nodes was 91.2%. CONCLUSION: The identification rate of SLNB and the accuracy of intraoperative frozen section examination after NAC are comparable to the results without NAC in patients with early breast cancer. However considering the high false negative rates, general application of SLNB after NAC should be avoided. Patients with progesterone-positive tumors and non-triple-negative breast cancers may be a select group of patients in whom SLNB can be employed safely after NAC, but further studies are necessary.

Horseshoe kidney (HSK) is the most common congenital abnormality of the urologic system encountered during abdominal aortic aneurysm (AAA) surgery. Here, the authors report a case of AAA coexisting with HSK that was successfully treated by open surgery. Two accessory renal arteries of 2.5 mm and 3.1 mm were reimplanted. One of the implanted arteries later occluded and infarct of the isthmus developed, but there was no impairment of renal function. The authors discuss the complexity of the surgical treatment of AAA coexisting with HSK, and place focus on which accessory renal arteries should be reconstructed.

PURPOSE: The purpose of this study was to review the daily practice of inferior vena cava filters (IVCFs) in a tertiary referral center in Korea and to reveal the retrieval rate and the methods for improving it. MATERIALS AND METHODS: Through the electronic medical record system, a retrospective review was performed on 115 consecutive patients who underwent placement of retrievable IVCFs between February 2000 and January 2011 in Seoul National University Hospital. RESULTS: IVCF placement was done in 115 cases (113 patients). There were 68 men (59.1%), and the mean age was 58.5+/-15.5 years (range, 10-96 years). The affiliated departments were Vascular Surgery (57 cases, 49.6%), and Internal Medicine (20 cases, 17.4%). Advanced malignancy was the most commonly associated disease (n=30, 26%). The indications for IVCF placement were categorized; absolute indications in 36 cases (31.3%), relative indications in 78 cases (67.8%), and prophylactic use in 1 case (0.9%). The most common indications were thrombolysis/thrombectomy for iliocaval deep vein thrombosis (DVT) (n=55, 47.8). Of the 115 filters, 68 were retrieved (retrieval rate, 59%). The most common cause of non-retrieval was chronic high risk of venous thromboembolism in 24 patients (51%), followed by residual proximal DVT (n=7, 15%), and negligence by unknown reasons (n=6, 13%). CONCLUSION: To improve the retrieval rate, the number of follow-up losses to vascular specialists must be decreased, which can be achieved by establishment of a dedicated IVC filter clinic, implementation of a filter registry, and regular education for medical teams and patients along with their families.

Upper extremity deep vein thrombosis (DVT) is an unusual condition compared to lower extremity DVT, and it represents about 10% of all DVTs. We report a case of upper extremity DVT after clavicle fracture and immobilization.

Adventitial cystic disease (ACD) is a very rare condition characterized by the accumulation of a cyst filled with gelatinous substance in the adventitia of a vessel adjacent to the joint area. The cyst usually compresses the vessel lumen, causing claudication or leg swelling. The disease usually affects the popliteal artery. However, several cases of venous ACDs particularly in the common femoral or external iliac vein have been reported. The definition, diagnosis, and optimal treatment of ACD remain controversial because of its rarity and the inconsistent use of terminology. The heterogeneity of the reported cases is more prominent in venous ACD. Herein, the accurate terminology of cysts correlated to the joint (synovial cyst, ganglion cyst, and adventitial cyst) and the pathogenesis, anatomy, and optimal therapy of venous ACD are discussed in detail to establish reporting standards for future studies.
