Exertional Lower Extremity Pain in a Triathlete Caused by External Iliac Artery Endofibrosis: A Case Report.

CASE: This report describes a 25-year-old female professional triathlete with right external iliac artery endofibrosis (EIAE) that was definitively diagnosed on contrast-enhanced magnetic resonance images obtained immediately after treadmill running. The EIAE was treated by percutaneous transluminal angioplasty. By 8 weeks after surgery, she had no symptoms of claudication or pain in the right thigh after a 1-hour running session. There has been no recurrence in 1 year postoperatively. CONCLUSION: EIAE is a rare condition and difficult to diagnose in a timely manner because symptoms and radiographic imaging features appear only during intense exercise. Our patient was successfully treated with percutaneous transluminal angioplasty.

Endovascular repair of bilateral isolated common iliac artery aneurysms with unsuitable anatomy utilizing an aortic bifurcated unibody endograft and modified sandwich technique to preserve pelvic blood flow: a case series.

Bilateral isolated common iliac artery aneurysms (CIAAs) are rare, and endovascular repair of CIAAs has emerged as an alternative to traditional open surgical repair. The primary goal of therapy is to exclude the aneurysm sac while maintaining perfusion of at least one internal iliac artery (IIA) to prevent pelvic ischemia. Although the iliac branch device (IBD) has improved the feasibility of preserving the IIA, its applicability is limited to a specific subset of aneurysm anatomy. We present a case series of three patients with bilateral isolated CIAAs in whom preoperative CT scans revealed an absence of a landing zone, the diameter of proximal CIA diameter was less than 13.0 mm, and normal diameter of the nonaneurysmal infrarenal aorta, making it challenging to use an IBD alone or a standard bifurcated aortic endograft to provide a proximal landing zone for iliac artery stenting. To overcome the small diameter of the infrarenal aorta, we implanted an aortic bifurcated unibody endograft. Then, we utilized a balloon-expandable covered stent-graft with overdilation as a modified sandwich technique to create an "eye of the tiger" configuration to prevent gutter leakage. The final angiography performed during the procedure revealed successful exclusion of the aneurysms, with blood flow to the right IIA and no type III endoleak. During the postoperative follow-up period, no patients exhibited symptoms associated with pelvic ischemia. There were no endoleaks or sac expansions on the two-year follow-up CT scans, and all external and internal iliac graft limbs were patent. This study demonstrated that a combination of an aortic bifurcated unibody endograft and a modified sandwich technique can effectively treat bilateral isolated CIAAs with certain anatomical constraints.

Encountering the corona mortis vessel during laparoscopic totally extraperitoneal mesh hernioplasty and its significance.

Corona mortis (CM) is an anastomotic vessel between the inferior epigastric or external iliac vessels and the obturator or internal iliac vessels. The Latin meaning of it is 'crown of death' which corresponds to massive haemorrhage caused by injury to this vessel during surgery. The incidence of this vessel is around 50% in the hemipelvis. We are presenting an intraoperative video of a right laparoscopic totally extraperitoneal mesh hernioplasty demonstrating a CM artery in the right hemipelvis. Care was taken to prevent injury to this vessel. CO2 insufflation pressure was reduced to less than 10 mm Hg to see any venous variant of this vessel. Carefully, polypropylene mesh was placed without a fixation device. Anatomical knowledge of the CM vessel is therefore essential in preventing injury for surgeons who approach the inguinal and retropubic regions.

Endovascular repair of an abdominal aortic aneurysm with external iliac artery occlusion using VBX as the contralateral leg via axillary delivery: A case report.

RATIONALE: A hostile iliac access route is an important consideration when enforcing endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA). Herein, we report a case of AAA with unilateral external iliac artery occlusion, for which bifurcated EVAR was successfully performed using a single femoral and brachial artery access. PATIENT CONCERNS: A 76-year-old man who had undergone surgery for lung cancer 4.5 years prior was diagnosed AAA by computed tomography (CT). DIAGNOSIS: Two and a half years before presentation, CT revealed an infrarenal 48 mm AAA, which had enlarged to 57 mm by 2 months preoperatively. CT identified occlusion from the right external iliac artery to the right common femoral artery, with no observed ischemic symptoms in his right leg. The right external iliac artery, occluded and atrophied, had a 1 to 2 mm diameter. INTERVENTION: Surgery was commenced with the selection of a Zenith endovascular graft (Cook Medical) with an extended body length. Two Gore Viabahn VBX balloon expandable endoprosthesis (VBX; W.L. Gore & Associate) were delivered from the right axilla as the contralateral leg. OUTCOMES: CT scan on the 2nd day after surgery revealed no endoleaks. LESSONS: While the long-term results remain uncertain, this method may serve as an option for EVAR in patients with unilateral external iliac artery occlusion.

Superficial Circumflex Iliac Artery Perforator Flap Reconstruction of the Upper Extremity.

The superficial circumflex iliac artery perforator (SCIP) flap is thin, pliable tissue well suited for reconstruction of injuries of the hand and upper extremity. Based upon perforators from the superficial circumflex iliac artery, the SCIP flap has advantages over the traditional groin flap due to reduced need for secondary procedures and improved donor site morbidity This article offers a detailed exploration of the SCIP flap design and technique, its advantages over traditional methods, and its potential applications in reconstructive surgery. Post-operative care and critical points are also discussed, and case examples are provided to guide readers through the intricacies of the technique, emphasizing the surgical skill and precision required for successful implementation.

High-frequency ultrasound-assisted perforator mapping enhances efficiency in microsurgical reconstruction using thin ALT and SCIP flaps.

BACKGROUND: With the growing demand for the use of thin perforator flaps, obtaining knowledge on the superficial anatomy of perforators is imperative for stable flap elevation. Conventional modalities for perforator mapping fall short in providing such information. High-frequency ultrasound (HFUS), known for visualizing the superficially located anatomic structures, may potentially fill this void. This study aimed to evaluate the effectiveness of HFUS in the outcome of anterolateral thigh (ALT) and superficial circumflex iliac artery perforator (SCIP) flap-based reconstructions. METHODS: Consecutive patients who underwent free ALT or SCIP flap-based reconstruction from January 2021 to November 2022 were retrospectively reviewed. Perforator mapping was conducted using a handheld Doppler during the first year, while HFUS was used in the latter part. The two techniques were compared in terms of flap harvesting time and perfusion-related complication rates while considering the flap elevation plane. RESULTS: In total, 123 cases were analyzed, including 82 ALT flaps (41 in each group) and 41 SCIP flaps (16 in the Doppler and 25 in the HFUS group). The time required for flap elevation exhibited a tendency to decrease in the HFUS group, with a significant difference observed in cases involving thin flap elevation (super-thin ALT flaps and pure-skin-perforator SCIP flaps). Compared with the Doppler group, the HFUS group demonstrated significantly lower rates of PRCs, particularly partial flap necrosis. This difference remained significant in multivariable analyses. CONCLUSION: Our results suggest that HFUS might be an appealing modality for perforator mapping in cases requiring thin ALT and SCIP flap.

[Choice of hybrid interventions for iliac-femoral arterial lesions]. / Vybor ob"ema gibridnogo vmeshatel'stva pri porazhenii arterii podvzdoshno-bedrennogo segmenta.

OBJECTIVE: To compare the short-term and long-term outcomes of hybrid interventions after various infrainguinal reconstructions (restoration of blood flow through superficial femoral artery and pulsatile blood flow through deep femoral artery) in patients with iliac-femoral arterial disease. MATERIAL AND METHODS: A retrospective analysis included patients after hybrid iliac-femoral interventions between 2014 and 2018. These interventions included stenting of iliac arteries and various open infrainguinal reconstructions. The first group (n=41) consisted of patients who underwent reconstruction of superficial femoral artery, the second group (n=88) - restoration of pulsatile blood flow in deep femoral artery. We analyzed the Rutherford score, perioperative complications, primary patency rates and limb salvage rates after 12 months in both groups. RESULTS: Significant improvement (Rutherford score +3) was achieved in 28 (70%) and 14 (15.9%) patients, respectively (p<0.05). There were no significant between-group differences in the number of postoperative complications. Surgery time was longer in the first group (median 160 and 130 min, respectively, p<0.05). However, intraoperative blood loss was similar. Primary patency rates after 12 months were 82.4% and 95.1%, respectively (p=0.054). Limb salvage rates after 12 months were 94.7% and 100%, respectively (p<0.05). CONCLUSION: This study highlights the potential advantages of restoring pulsatile blood flow through the deep femoral artery in hybrid interventions. Higher primary patency and limb salvage rates in the second group indicate better long-term outcomes after restoration of blood flow through the deep femoral artery. Further prospective studies are needed to confirm these results and determine the underlying mechanisms of differences.

Pedicled chimeric superficial circumflex iliac artery perforator (SCIP) flap with external oblique fascia for vesicocutaneous bladder fistula repair: A case report and literature review on the utility of pedicled chimeric SCIP.

Following its initial description by Koshima in 2004, the superficial circumflex iliac artery perforator (SCIP) flap has become a ubiquitous and extremely useful flap in coverage of defects whereby bulkiness must be avoided. It also allows direct closure and concealment of the donor site. Its use as a free tissue transfer has been demonstrated by various surgeons globally. Nevertheless, there are few cases illustrating the utility of the pedicled SCIP flap in the reconstruction of lower abdominal defects. We present a case of a pedicled SCIP flap utilized as a chimeric flap incorporating external oblique muscle fascia on a deep branch along with the typical fasciocutaneous component based on the superficial branch to cover the suprapubic defect after vesicocutaneous fistula repair. We thereafter report on the literature of pedicled chimeric SCIP flap for locoregional reconstruction. A 26-year-old female was referred to the Plastic and Reconstructive Surgery unit after suffering a functional bladder outlet obstruction necessitating the creation of a urinary stoma. Subsequently, stoma obstruction occurred, and a suprapubic catheter was performed that was complicated by infection and resulted in the development of a vesicocutaneous fistula. Accordingly, the urological surgeons were planning surgical closure of the suprapubic vesicocutaneous defect, measuring 5 × 4 cm. A pedicled SCIP flap was designed to match the defect size; and raised as a chimeric flap with external oblique muscle fascia based on the deep branch, along with the fasciocutaneous component based on the superficial branch. The external oblique fascial component was used to secure the suture line of fistula repair, over which the fasciocutaneous component was inset, effectively double breasting the fistula repair and full thickness lower abdominal defect. The patient had an unremarkable postoperative recovery and has since been followed up in the outpatient setting without complication for the past 24 months. Robust coverage of the suprapubic defect was reliably achieved and no further fistulation has occurred. This case illustrates that a pedicled SCIP flap can be harvested as a chimeric flap and used to reliably cover defects in the infra-umbilical region.

Triglyceride-glucose index for predicting in-stent restenosis in patients with iliac artery stenosis after percutaneous intervention with stents.

OBJECTIVE: To evaluate the triglyceride-glucose index (TyG index) for predicting in-stent restenosis in patients with iliac artery stenosis after percutaneous intervention with stents. PATIENTS AND METHODS: Subjects with iliac artery stenosis, who underwent an iliac stent intervention and were followed up for at least 2 years were included in the study. Subjects were grouped according to TyG index (Group A, TyG index ≤8.848; Group B 8.849 ≤TyG index ≤9.382 and Group C TyG index ≥9.383). The subject's baseline characteristics, blood parameters, claudication distance, Transatlantic Intersociety Consensus classification, target lesion localization, stent direction, number of stents that were applied, and stent type were noted. Pre- and 1st and 2nd-year post-procedure Rutherford statuses, ankle-brachial index, and stenosis degree were recorded. To calculate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), Group B and Group C were combined and compared with Group A. RESULTS: In total, 255 subjects were evaluated (female, n=77-30.2%, male, n=178-69.8%). The mean age of the subjects was 66.00±10.00 years (range from 39 to 90 years). The pre-procedure Rutherford measurements were significantly different among the groups (p=0.001). The rates of mild claudication and resting pain in Group A were higher than those in Groups B and C. The rate of moderate claudication in Group C was higher than that in Groups A and B. The rate of severe claudication in Group B was higher than that in Groups A and C. One year after the procedure, there were more asymptomatic cases in Group A than in Groups B and C (p=0.001). The rate of mild claudication in Group C was lower than that in Groups A and B. The rate of moderate claudication in Group C was higher than that in Group A. The rate of severe claudication in Group C was higher than that in Groups A and B. Two years after the procedure, the Rutherford measurements and the rates of mild claudication in Groups A and B were higher than those in Group C. The rate of severe claudication in Group C was higher than that in Groups A and B (p=0.001). One year after the procedure, the computed tomography angiography (CTA) measurements and the rate of full patency in Group A were higher than that in Groups B and C. The rate of 0-50% stenosis in Group B was higher than that in Groups A and C. The rate of 50-70% stenosis in Group C was higher than that in Group A. Two years after the procedure, the CTA measurements and the rates of 70-99% stenosis and 100% occlusion in Group C were higher than those in Groups A and B. The TyG index has high specificity and NPV. However, specificity and PPV levels were found to be quite low. CONCLUSIONS: The TyG index was found to be an easy-to-use marker for predicting in-stent restenosis in patients with iliac artery stenosis after percutaneous intervention with stents.

Interposition of right internal iliac artery free-graft for left coronary artery reimplantation in adults with anomalous left coronary artery originating from the pulmonary artery: case series and long-term results.

Anomalous left coronary artery originating from the pulmonary artery (ALCAPA) is an infrequent congenital anomaly. Presentation of this syndrome is rare in adults. Nevertheless, adult patients are at risk of ischaemia, arrhythmias or sudden cardiac death and always require surgical intervention. At our institution, a specific technique of interposition of the right internal iliac artery as a free-graft for left coronary artery reimplantation was used in adult ALCAPA patients. The aim of this report is to determine long-term results and experiences with this surgical technique.

Immunoglobulin G4-Related Disease Complicating Ruptured Isolated Iliac Artery Aneurysm: A Complex Management Dilemma.

BACKGROUND Managing IgG4-related disease (IgG4-RD) in the context of vascular complications, such as aneurysms, poses significant challenges, particularly when considering surgical intervention options. The risk of rupture and infection in patients on long-term glucocorticoid therapy complicates treatment decisions. CASE REPORT A 63-year-old woman with a history of IgG4-RD presented with a ruptured right iliac artery aneurysm. She was on long-term oral glucocorticoid therapy. Initial emergency endovascular stent graft implantation was followed by embolization for suspected arterial bleeding and subsequent Salmonella bacteremia. Repeated hospitalizations involved stent graft removal and surgical repair due to persistent infection. Over 2 years, the patient required multiple pelvic drainages and long-term antibiotic and prednisolone therapy, yet her quality of life remained compromised. CONCLUSIONS Our case highlights the unique challenges and considerations in the treatment of IgG4-related aneurysms. Patients with IgG4-RD who are on long-term oral glucocorticoids have an inherent risk of aneurysm rupture. We believe regular follow-ups to monitor the progression of the aorta and iliac arteries into aneurysms are essential. For patients who have developed aneurysms, it is advisable to reduce the dosage of glucocorticoids or even consider surgical treatment as soon as possible. As for the choice of surgical method, there is no consensus yet. While endovascular treatment is less invasive and quicker, it can increase the risk of rupture and bleeding. Open surgery might be a better option. More data are needed to make a definitive judgment.

[Clinical effects of free superficial circumflex iliac artery superficial branch perforator flap combined with full-thickness skin graft far from the flap donor site in repairing the large wounds in extremities].

Objective: To investigate the clinical effects of free superficial circumflex iliac artery (SCIA) superficial branch perforator flap combined with full-thickness skin graft far from the flap donor site in repairing the large wounds in extremities. Methods: The study was a retrospective observational study. From January 2020 to June 2022, 19 patients with large wounds in extremities who met the inclusion criteria were admitted to the First Affiliated Hospital of Bengbu Medical College, including 15 males and 4 females, aged 28-75 years. The debridement, fracture reduction and fixation, tendon, vessel, and nerve repair, and vacuum sealing drainage were performed in the first stage surgery. After debridement in the second stage surgery, the total wound area was 13.0 cm×8.0 cm-34.0 cm×15.0 cm. The tendon and bone exposed wound with area of 9.0 cm×6.0 cm-14.0 cm×7.0 cm was repaired with free SCIA superficial branch perforator flap with area of 10.0 cm×6.5 cm-15.0 cm×8.0 cm. The remaining granulation tissue wound with area of 5.0 cm×3.5 cm-13.0 cm×8.0 cm was repaired with full-thickness skin graft far from the flap donor site with area of 5.0 cm×3.5 cm-13.0 cm×8.0 cm. All the wounds in donor site were sutured. The operation time and amount of bleeding of patients during the surgery were recorded, the survival of flap and skin graft were observed after surgery. During follow-up, the flap and skin graft, scar in the donor site and its effect on donor site function were observed. At the last follow-up, the satisfaction of patients with the efficacy was evaluated by the efficacy satisfaction rating score. Results: The operation time of patients was 2.0-3.5 h. The amount of bleeding of patients during the surgery was 100-320 mL. One patient had ecchymosis and venous crisis in the edge of flap on the second day after surgery, and the flap survived after exploration. The flaps of the other patients survived smoothly. The skin grafts of patients all survived smoothly. Two patients had bloated flaps due to obesity in the later stage, and the expected results were achieved after flap thinning surgery 6 months after operation. During the follow-up of 6 to 24 months, the flaps had good elasticity and soft texture, and the skin grafts had no wear or ulceration; linear scars were left in all the donor sites but their functions were not affected. The patients were all satisfied with the efficacy. Conclusions: Free SCIA superficial perforator flap combined with full-thickness skin graft far from the donor site was used to repair the large wounds in extremities, which was safe, reliable, and less traumatic and short in operation time, and resulted in good postoperative appearance and function in the donor sites and recipient sites.

Kidney transplantation using ipsilateral arterial and contralateral venous anastomosis in a patient with failing vascular access.

Herein, we describe our surgical technique and outcome of a kidney transplant in a patient with failing vascular access. A right donor kidney was transplanted into the right iliac fossa with an end-to-side arterial anastomosis to the ipsilateral right common iliac artery and end-to-side venous anastomosis to the contralateral left common iliac vein. The possibility of performing an ipsilateral arterial and contralateral venous anastomosis has been shown here to be successful. No post-operative surgical complications were encountered.

Diagnosis of chronic lliac venous obstruction

Stenting has become the first line of treatment for symptomatic chronic iliofemoral venous obstruction in patients with quality-of-life impairing clinical manifestations who have failed conservative therapy. Patient selection for such intervention is however dependant on clear identification of relevant clinical manifestations and subsequent testing to confirm the diagnosis. In this regard the physician engaged in management of such patients need to be well aware of symptoms and signs of chronic iliofemoral venous obstruction (CIVO), instruments used to grade chronic venous insufficiency (CVI) and determine quality of life in addition to diagnostic tests available and their individual roles. This review serves to provide an overview of the diagnosis of CIVO and patient selection for stenting.

Evaluation of the holding-up uterus technique for placenta accreta spectrum cesarean hysterectomy in shocked patients with a high shock index: a case series study.

BACKGROUND: Placenta accreta spectrum (PAS) cesarean hysterectomy is performed under conditions of shock and can result in serious complications. This study aimed to evaluate the usefulness of the "Holding-up uterus" surgical technique with a shock index (S.I.) > 1.5. METHODS: Twelve patients who underwent PAS cesarean hysterectomy were included in the study. RESULTS: Group I had S.I. > 1.5, and group II had S.I. ≤ 1.5. Group I had more complications, but none were above Grade 3 or fatal. Preoperative scheduled uterine artery embolization did not result in serious complications, but three patients who had emergency common iliac artery balloon occlusion (CIABO) and a primary total hysterectomy with S.I. > 1.5 had postoperative Grade 2 thrombosis. Two patients underwent manual ablation of the placenta under CIABO to preserve the uterus, both with S.I. > 1.5. CONCLUSIONS: The study found that the "Holding-up uterus" technique was safe, even in critical situations with S.I. > 1.5. CIABO had no intervention effect. The study also identified assisted reproductive technology pregnancies with a uterine cavity length of less than 5 cm before conception as a critical factor.
