Ann Vasc Surg 2024; 105:82-88. [PMID: 38588956 DOI: 10.1016/j.avsg.2024.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 11/05/2023] [Accepted: 02/04/2024] [Indexed: 04/10/2024]
Abstract
BACKGROUND The use of cryopreserved saphenous veins (CSVs) for the treatment of lower extremity peripheral arterial disease is an attractive option when there is no available autogenous vein. Prior studies found CSVs are at risk for aneurysmal degeneration requiring reoperation. As the management of these complications and patient outcomes is not well described, the objective of this case series is to describe the open and endovascular management of degenerative CSVs at a tertiary community center. METHODS All CSVs implanted for lower extremity bypass at our institution between 2001 and 2021 were retrospectively reviewed. All CSVs with evidence of aneurysmal change were included in this study. CSVs with evidence of active infection were excluded. The decision to intervene was left to the discretion of the operating surgeon. Demographic data, indications for the index operation, and details about subsequent interventions for degenerative CSVs were recorded. Study end points included limb salvage and continued patency. Demographic data, indications for the index operation, and details about subsequent interventions for degenerative CSVs were recorded. RESULTS Seventeen bypasses were identified to have aneurysmal degeneration in 13 patients in the absence of infection between 2001 and 2021. Nine of the 13 patients were male, and the average age and body mass index during the index procedure were 72 and 28, respectively. Indications for the index bypass included acute limb ischemia (9), popliteal aneurysm (2), and chronic limb threatening ischemia with Rutherford's class IV (5) and V (1). The mean time between the index procedure and first graft revision due to aneurysmal changes was 4 years. Most of the aneurysms did not occur at the site of anastomosis with 13 occurring in the body of the graft. Thirteen grafts were managed with open surgery and 3 were managed with endovascular techniques. All endovascular repairs were managed via covered stenting. Patients were followed for an average duration of 7 years from the initial bypass and 2 years from their last aneurysmal repair. Limb salvage in this cohort was 87% with 2 limbs requiring amputation, all of whom underwent open reconstruction. The mortality rate in this series was 54% and no patients died due to complications from their graft. Continued patency on Kaplan Meier survival curve analysis was 79% at 6 months, 65% at 1 year, 54% at 3 years, and 27% at 5 years. CONCLUSIONS In our experience, aneurysmal degeneration of CSV grafts was mostly managed with standard open surgical techniques, although endovascular therapy also proved acceptable. Limb salvage rates and continued patency of repair at 1 year in this cohort were acceptable. This case series highlights the importance of diligent surveillance for patients with CSVs.

Contemporary outcomes for arterial reconstruction with non-saphenous vein cryo-preserved conduits. J Vasc Surg 2024; 79:1457-1465. [PMID: 38286153 DOI: 10.1016/j.jvs.2024.01.201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 12/06/2023] [Accepted: 01/21/2024] [Indexed: 01/31/2024]
Abstract
OBJECTIVE Cryopreserved (CP) products are utilized during challenging cases when autogenous or prosthetic conduit use is not feasible. Despite decades of experience with cadaveric greater saphenous vein (GSV), there is limited available data regarding the outcomes and patency of other CP products, specifically arterial and deep venous grafts. This study was designed to evaluate outcomes of non-GSV CP conduits in patients undergoing urgent, emergent, and elective arterial reconstruction at our institution. We hypothesized that non-GSV CP allografts have adequate patency and outcomes and are therefore a feasible alternative to GSV in settings where autologous graft is unavailable or prosthetic grafts are contraindicated. METHODS This study was approved by the Institutional Review Board at our institution. We retrospectively reviewed charts of patients undergoing arterial reconstructions using CP conduits from 2010 to 2022. Data collected included demographics, comorbidities, smoking status, indications for surgery, indication for CP conduit use, anatomic reconstruction, urgency of procedure, and blood loss. Time-to-event outcomes included primary and secondary graft patency rates, follow-up amputations, and mortality; other complications included follow-up infection/reinfection and 30-day complications, including return to the operating room and perioperative mortality. Time-to-event analyses were evaluated using product-limit survival estimates. RESULTS Of 96 identified patients receiving CP conduits, 56 patients received non-GSV conduits for 66 arterial reconstructions. The most common type of non-GSV CP product used was femoral artery (31 patients), followed by aorto-iliac artery (22 patients), and femoral vein (19 patients), with some patients receiving more than one reconstruction or CP product. Patients were mostly male (75%), with a mean age of 63.1 years and a mean body mass index of 26.7 kg/m2. Indications for CP conduit use included infection in 53 patients, hostile environment in 36 patients, contaminated field in 30 patients, tissue coverage concerns in 30 patients, inadequate conduit in nine patients, and patient preference in one patient. Notably, multiple patients had more than one indication. Most surgeries (95%) were performed in urgent or emergent settings. Supra-inguinal reconstructions were most common (53%), followed by extra-anatomic bypasses (47%). Thirty-day mortality occurred in 10 patients (19%). Fifteen patients (27%) required return to the operating room for indications related to the vascular reconstructions, with 10 (18%) cases being unplanned and five (9%) cases planned/staged. Overall survival at 6, 12, and 24 months was 80%, 68%, and 59%, respectively. Primary patency at 6, 12, and 24 months was 86%, 70%, and 62%, respectively. Amputation freedom at 6 months, 12 months, and 24 months was 98%, 95%, and 86%, respectively for non-traumatic indications. CONCLUSIONS Non-GSV CP products may be used in complex arterial reconstructions when autogenous or prosthetic options are not feasible or available.

Abstract
Cryopreserved vein allografts are used as alternative conduits for infrainguinal bypass but are prone to aneurysmal degeneration. A 60-year-old man presented with a pulsatile, tender right groin mass 2 years after thrombosis of a cryopreserved vein jump graft emanating from a prosthetic axillary to profunda bypass. Intraoperatively, the aneurysm was consistent with isolated dilatation of the hood of the thrombosed cryopreserved vein graft. This was excised and repaired with bovine pericardial patch angioplasty. The patient recovered with no recurrence for 2 years. Aneurysmal degeneration of the cryopreserved vein allograft can occur even after graft thrombosis.

Abstract
BACKGROUND Pediatric patients with biliary atresia (BA) often present liver cirrhosis-associated portal hypertension and portal vein (PV) hypoplasia. For successful liver transplantation (LT), it is essential to maintain sufficient PV inflow through stenosis-free PV reconstruction with effective ligation of collateral veins. The aim of this study was to assess the clinical usability of intraoperative cine-portogram (IOCP) in young pediatric patients who underwent LT for BA. METHODS Medical records of pediatric patients younger than 10 years who underwent primary LT for BA from 2018 to 2020 were reviewed. RESULTS A total of 31 patients had undergone Kasai portoenterostomy soon after birth. Their median ages at Kasai portoenterostomy and LT were 1 and 11 months, respectively. Types of LT were living-donor LT in 13, deceased-donor split LT in 15, and deceased-donor whole LT in three patients. PV interposition using an iliac vein homograft was performed in 28 patients receiving partial liver grafts. Side-to-side PV unification venoplasty was performed in three patients undergoing whole LT. All patients underwent ligation of collateral veins. IOCP was performed in 6 (19.4%) patients. Four showed no or faint residual venous collaterals. Collateral vein embolization and endovascular stenting were performed in one patient each. PV insufficiency-free survival rate was 100% at 1 year and 93.8% at 3 years. All patients are currently alive with a median follow-up period of 23 months. CONCLUSIONS Intraoperative cine-portogram can be a useful method for identification and embolization of residual portosystemic collateral veins in young pediatric patients who undergo LT for biliary atresia.

Abstract
Obtaining tumor-free resection margins is one of the most important factors for achieving favorable prognosis of patients undergoing resection for hepatobiliary malignancies. In this study, we present our experience of portal vein (PV) wedge resection and patch venoplasty using autologous or homologous vessel grafts for resecting perihilar cholangiocarcinoma, hepatocellular carcinoma, and distal bile duct cancer. Case 1 was 68-year-old male patient with type IV perihilar cholangiocarcinoma who underwent central bisectionectomy with caudate lobectomy and bile duct resection, and PV wedge resection and patch venoplasty with a cryopreserved iliac vein allograft patch. This patient survived 14 months after surgery. Case 2 was 77-year-old male patient with type IIIA perihilar cholangiocarcinoma who underwent left medial sectionectomy with caudate lobectomy, bile duct resection, and PV wedge resection and patch venoplasty with a cryopreserved iliac vein allograft patch. This patient survived 17 months after surgery. Case 3 was 54-year-old male patient with hepatitis B virus-associated liver cirrhosis and hepatocellular carcinoma with PV tumor thrombus who underwent left hepatectomy. The PV wall defect was repaired with an autologous greater saphenous vein patch. This patient survived 11 months after surgery. Case 4 was 65-year-old female patient with distal bile duct cancer who underwent pylorus-preserving pancreaticoduodenectomy, and main PV wedge resection and patch venoplasty with a cryopreserved iliac artery allograft patch. This patient survived 21 months after surgery. In conclusion, PV wedge resection and patch venoplasty can be used to facilitate complete tumor resection in patients undergoing various extents of surgical resection for hepatobiliary malignancies.

Abstract
Infection of arterial vascular grafts is a rare but utterly severe complication in vascular surgery. Therapeutic policy in patients with graft infection has not been standardized, to be determined individually. One of the variants of surgical treatment is considered to be repeat aortic repair using a cadaveric graft. Presented in the article is a clinical case report concerning a 60-year-old male patient previously subjected to aortofemoral bifurcation bypass grafting with stage IV ischaemia of lower limbs according to the Pokrovsky-Fontaine classification. In the early postoperative period the events of critical ischaemia were not arrested. Due to the presence of a block of the femoropopliteal segment, as the second stage 3 days after the primary operation, the patient underwent autovenous femoropopliteal bypass grafting with a reversed autovein above the knee-joint fissure. The clinical course of critical ischaemia of the limb was relieved. During subsequent 8 months of follow up his state remained stable. Eight months after the primary operation he developed purulent discharge from the postoperative scar on the left femur. In the setting of the Purulent Surgery Department, the patient was emergently subjected to opening and drainage of the abscess of the postoperative scar. On the bottom of the wound there was a freely lying branch of a synthetic vascular prosthesis. Computed tomography revealed infection of the entire synthetic prosthesis and aneurysms of distal anastomoses. Given extremely high risk for the development of arrosive haemorrhage, a decision was made on operative treatment - repeat prosthetic repair of the abdominal aorta with a cadaveric allograft. At the Vascular Department of the Clinic of Faculty Surgery, laparotomy was performed, with removal of the infected graft, followed by debridement of the retroperitoneal space and repeat aortofemoral bifurcation prosthetic repair of the abdominal aorta with a cadaveric allograft. The wound healed with first intention. There was no evidence of infectious process relapse. The patient was discharged on postoperative day 15 in a satisfactory condition. The duration of follow up amounted to 6 months. The control examination showed that the pain-free walking distance was 500 m. Doppler ultrasonography demonstrated that the graft was functioning, with no signs of either anastomotic aneurysms or suppuration of the retroperitoneal space.

Abstract
Graft size matching is essential for successful liver transplantation in infant recipients. We present our technique of graft dextroplantation used in an infant who underwent living donor liver transplantation (LDLT) using a reduced left lateral section (LLS) graft. The patient was an 11-month-old female infant weighing 7.8 kg with hepatoblastoma. She was partially responsive to systemic chemotherapy. Thus, LDLT was performed to treat the tumor. The living donor was a 34-year-old mother of the patient. After non-anatomical size reduction, the weight of the reduced LLS graft was 235 g, with a graft-to-recipient weight ratio of 3.0%. Recipient hepatectomy was performed according to the standard procedures of pediatric LDLT. At the beginning of graft implantation, the graft was temporarily placed at the abdomen to determine the implantation location. The graft portal vein was anastomosed with an interposed external iliac vein homograft. As the liver graft was not too large and it was partially accommodated in the right subphrenic fossa, thus the abdominal wall wound was primarily closed. The patient recovered uneventfully. An imaging study revealed deep accommodation of the graft within the right subphrenic fossa. The patient has been doing well for six months without any vascular complications. This case suggests that dextroplantation of a reduced LLS graft can be a useful technical option for LDLT in infant patients.

Abstract
The orifice size of the LHV trunk in LLS grafts is often too small for direct anastomosis. Several methods were developed to enlarge the graft and recipient hepatic vein orifices. This study described our surgical techniques to secure hepatic vein reconstruction in infant recipients and analyzed the patency outcomes. Twelve infants undergoing pediatric LDLT were selected during 2-year study period between January 2018 and December 2019. Surgical techniques and vascular complications of graft hepatic vein outflow were analyzed. The mean recipient age was 12.5 ± 4.5 months; mean body weight was 9.4 ± 1.0 Kg; and mean graft-recipient weight ratio was 2.8 ± 0.6%. Primary diseases were biliary atresia in six patients, metabolic diseases in two, hepatoblastoma in two, and acute liver failure in two. Eight LLS grafts were recovered through an open method, and four LLS grafts were recovered through a laparoscopic method. A small superficial LHV branch was present in five of 12 LLS grafts, which was opened to widen the graft hepatic vein orifice. Incision-and-patch venoplasty was performed in 10, unification venoplasty in 1 and no venoplasty in 1. All four LLS grafts recovered through a laparoscopic approach required circumferential vein patch because of very short hepatic vein stump. No patient experienced graft hepatic vein-associated vascular complications during the follow-up period of 19.3 ± 9.3 months. Our surgical techniques with incision-and-patch venoplasty for LLS grafts is beneficial to reduce the risk of hepatic vein outflow obstruction in recipients receiving LLS grafts.

Abstract
Margin-free resection is one of the most important factors for favorable prognosis in patients undergoing resection for hepatobiliary malignancies. Herein, we present two cases of hepatobiliary malignancies in patients who underwent bile duct resection combined with hilar portal vein (PV) resection and vein allograft patch plasty. The first case was a 51-year-old female patient with gallbladder cancer, in whom we performed extended cholecystectomy, bile duct resection and extensive lymph node dissection. The tumor-invaded PV wall was meticulously excised and the defect was repaired with a cryopreserved iliac vein allograft patch. The extent of the tumor was pT4N2M0 (stage IVB), thus concurrent chemoradiation therapy and adjuvant chemotherapy were performed. This patient is currently alive for 7 years after surgery without any evidence of tumor recurrence. The second case was a 79-year-old male patient with perihilar cholangiocarcinoma of type I and gallbladder cancer, in whom extended bile duct resection and extensive lymph node dissection were performed. The extent of the bile duct tumor was pT4N1M0 (stage IVA) and that of gallbladder tumor was pT2N0M0 (stage II). No additional treatment was provided because of old age and poor general condition. This patient passed away 11 months after surgery due to rapid progression of tumor recurrence. In conclusion, hilar PV wedge resection and roofing patch venoplasty is a useful option to facilitate complete tumor resection in patients undergoing bile duct resection for hepatobiliary malignancy.

Abstract
Laparoscopically harvested left liver (LL) grafts have drawbacks with respect to the size and shape of graft hepatic vein orifices. We present two cases of pediatric living donor liver transplantation (LDLT) using laparoscopically harvested LL grafts and describe refined surgical techniques for graft hepatic vein venoplasty. The first case was a boy aged 4 years and 5 months, with hepatoblastoma. The donor was his 35-year-old mother, and LL graft weighed 315 g. Two separate openings of the graft at the left hepatic vein (LHV) and middle hepatic vein (MHV) were unified through septotomy and septoplasty, and cryopreserved vein homograft patch was attached. Standard procedures of LDLT were performed. This patient recovered uneventfully and has been doing well for 4 years without tumor recurrence. The second case was a 6-year-old girl with ornithine transcarbamylase deficiency. The donor was her 35-year-old mother, and the LL graft weighed 310 g. Two separate openings of graft MHV, with segment III and segment II veins, were unified through septoplasty, and vein patch was attached. Standard procedures of LDLT were performed. This patient has been doing well for 4 years. In conclusion, separate graft hepatic vein openings are a drawback of laparoscopically harvested LL grafts, which thus require unification venoplasty of customized design individually tailored for LL graft and pediatric recipient.

Abstract
Backgrounds/Aims To prevent large-for-size graft-related complications in small infant patients, the size of a left lateral segment (LLS) graft can be reduced to be a hyperreduced LLS (HRLLS) graft. Methods This study was intended to describe the detailed techniques for harvesting and implanting HRLLS grafts developed in a high-volume liver transplantation (LT) center. Results The mean recipient age was 4.0±1.7 months (range: 3-6) and body weight was 5.3±1.4 kg (range: 4.1-6.9). Primary diagnoses of the recipients were progressive familial intrahepatic cholestasis in 2 and biliary atresia in 1. The types of LT were living donor LT in 1 and split deceased donor LT in 2. Non-anatomical size reduction was performed to the transected LLS grafts. The mean weight of the HRLLS grafts was 191.7±62.1 g (range: 120-230) and graft-recipient weight ratio was 3.75±1.57% (range: 2.45-5.49). Widening venoplasty was applied to the graft left hepatic vein outflow orifice. Vein homograft interposition was used in a case with portal vein hypoplasia. Types of the abdomen wound closure were one case of primary repair, one of two-staged closure with a mesh, and one of three-staged repair with a silo and a mesh. All three patients recovered uneventfully from the LT operation and are doing well to date for more than 6 years after transplantation. Conclusions Making a HRLLS graft through non-anatomical resection during living donor LT and split deceased donor LT can be a useful option for treating small infant patients.

Refined surgical techniques to improve the patency of cryopreserved iliac artery homografts for middle hepatic vein reconstruction during living donor liver transplantation. Ann Surg Treat Res 2020; 99:294-304. [PMID: 33163459 PMCID: PMC7606128 DOI: 10.4174/astr.2020.99.5.294] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Revised: 07/16/2020] [Accepted: 07/30/2020] [Indexed: 12/14/2022] Open
Abstract
Purpose A cryopreserved iliac artery homograft (IAH) has not been considered suitable for middle hepatic vein (MHV) reconstruction during living donor liver transplantation (LDLT), primarily due to the low patency from its small diameter. We revised our surgical techniques for MHV reconstruction using an IAH to improve its patency. Methods This study analyzed the causes of early conduit occlusion and developed revised techniques to address this that had clinical application. Results The potential risk factors for early conduit occlusion were the small IAH size, small graft in the segment V vein (V5) and segment VIII vein (V8) opening, and small recipient MHV-left hepatic vein stump. These factors were reflected to our revised surgical methods which included endarterectomy of the atherosclerotic plaque, unification of the internal and external iliac artery branches for large V5, and branch-patch arterioplasty for large V8. IAH endarterectomy, branch unification technique, and branch-patch arterioplasty were applied to 8, 5, and 5 patients, respectively and resulted in 1-month occlusion rates of 37.5%, 20.0%, and 40.0%, respectively. The overall patency rates of the IAH-MHV conduits in our 18 patients were 66.7% at 1 month, 38.9% at 3 months, and 33.3% at 1 year. Conclusion Our refined MHV reconstruction using an IAH improved short-term MHV conduit patency, but did not effectively prevent early conduit occlusion, particularly with a small- or medium-sized IAH. Individualized reconstruction designs during LDLT operation are needed when an IAH is used for a modified right liver graft.

Graft outflow vein venoplasty for a laparoscopically harvested left lateral section graft in pediatric living donor liver transplantation. KOREAN JOURNAL OF TRANSPLANTATION 2020; 34:210-216.

Abstract
Laparoscopically harvested left lateral section (LLS) grafts have drawbacks regarding the size of the graft left hepatic vein (LHV) orifice although they have the merit of cosmetics concerning the donor’s wound. We present a case of pediatric living donor liver transplantation (LDLT) using a laparoscopically harvested LLS graft and describe the refined surgical techniques for graft LHV venoplasty with a circumferential vein patch. The patient was a 46-month-old boy with marked growth retardation who was diagnosed with progressive familial intrahepatic cholestasis type 2. The donor was his 25-year-old mother. The LLS graft weighed 285 g. A circumferential patch of external iliac vein homograft was attached to the graft LHV orifice after incisions were made at the medial wall of the LHV trunk and superficial LHV branch, which made the graft LHV orifice much larger. The recipient’s hepatic vein orifice was also enlarged by unifying the three hepatic vein orifices. Other surgical procedures followed the standard LDLT operation. This patient recovered uneventfully and has been doing well for 1 year. In conclusion, our incision-and-patch venoplasty to enlarge the graft outflow vein orifice was beneficial for reducing the risk of hepatic vein outflow obstruction in LDLT using a laparoscopically harvested LLS graft.

Abstract
Background: Prosthetic vascular graft infection (PVGI) remains a severe and challenging complication in vascular surgery with high morbidity and mortality rates. Incidence has been reported between 1% and 6%. The aim of this study was to report our experience in terms of general and surgical management as well as outcome, over 15 years. Methods: A retrospective consecutive study was conducted of all patients treated in our department for PVGI between January 2000 and December 2015. We analyzed all data relative to primary operation, duration interval between initial surgery and infections signs, infection site, type of microorganism involved, and surgical treatment modality, as well as evaluation of short- and long-term results. Results: Sixty-two patients were admitted for PVGI. Primary revascularization procedures consisted of a peripheral bypass in 42 (68%) patients and an aortic bypass in the remaining 20 (32%) patients. Median interval between primary procedure and reintervention was 3 months (interquartile range 17 [IQR 17]) in the peripheral group and 48 months (IQR 70.5) in the aortic group. Complete excision of the prosthetic graft was carried out in 85% of the cases. Thirty-day mortality was 0% and 9.5% in the aortic and peripheral group, respectively. The overall survival rate was 62.3% at 2-years, 46.4% in the aortic group, and 69.7% in the peripheral group. Conclusions: Prosthetic vascular graft infection needs a multidisciplinary management with appropriate antibiotherapy, radical removal of the infected graft, and in situ reconstruction. This strategy gives satisfactory results in terms of mortality, morbidity, patency rates, and infection control.

Abstract
Pediatric vascular disease is rare, and remains a big challenge to vascular surgeons. In contrast to adults, surgery for pediatric vascular disease is complicated by issues related to small size, future growth, and availability of suitable vascular conduit. During the last 30 years, 131 major vascular operations were performed in a tertiary referral center, Seoul National University Hospital, including aortoiliac aneurysm, acute or chronic arterial occlusion, renovascular hypertension, portal venous hypertension, trauma, tumor invasion to major abdominal vessels, and others. Herein we review on the important pediatric vascular diseases and share our clinical experiences on these rare diseases.
