A short report on the current landscape of Artificial Intelligence (AI) in vascular surgery in Pakistan.

This study focuses on the current applications, potential, and challenges to Artificial Intelligence (AI) integration in vascular surgery with specific emphasis on its relevance in Pakistan. Despite the benefits of AI in vascular surgery, there is a substantial gap in its adoption in Pakistan compared to global standards. In our context with limited resources and a scarcity of vascular surgeons, AI can serve as a promising solution. It can enhance healthcare accessibility, improve diagnostic accuracy, and alleviate the workload on vascular surgeons. However, hurdles including the absence of a comprehensive vascular surgery database, a shortage of AI experts, and potential algorithmic biases pose significant challenges to AI implementation. Despite these obstacles, the study underscores the imperative for continued research, collaborative efforts, and investments to unlock the full potential of AI and elevate vascular healthcare standards in Pakistan.

Development and content validation of a financial and functional outcomes tool for diabetes-related foot disease in patients undergoing major lower limb amputation: a prospective observational study from Pakistan.

OBJECTIVE: To develop and content validate a questionnaire to assess the financial and functional impact of major lower limb amputation in patients with diabetes-related foot disease. DESIGN: Prospective observational study. SETTING: This study was conducted at a tertiary care centre in Pakistan. PARTICIPANTS: We conducted a thorough literature review and a group interview with 10 participants, resulting in domain identification and item generation. The group included seven patients with diabetes-related foot disease who underwent major lower limb amputation and three caregivers. Subsequently, a focused group discussion was held to assess overlap and duplication among the items, and two rounds of content validation were carried out by five content and five lay experts in both English and Urdu. Question items with a Content Validity Index (CVI) score of >0.79 were retained, items with a CVI score between 0.70 and 0.79 were revised and items with a CVI score of <0.70 were excluded. RESULTS: The initial literature review and group interview resulted in 61 items in the financial and functional domains. After the focused group discussion, the questionnaire was reduced to 37 items. Following two rounds of content validation, the English questionnaire achieved the Scale-Content Validity Index/Average (S-CVI/Ave) of 0.92 and 0.89 on relevance and clarity, respectively. Similarly, the Urdu questionnaire achieved the S-CVI-Ave of 0.92 and 0.95, respectively. CONCLUSION: A 37-item multidimensional questionnaire was developed and rigorously content-validated to assess the financial and functional impact of major lower limb amputation in patients with diabetes-related foot disease. The questionnaire used in this study has shown robust content validity specifically for our population.

Managing Splenic Artery Pseudoaneurysms-An Experience from a Developing Country. A Retrospective Review.

Objectives: Splenic artery pseudoaneurysm is a rare but potentially fatal condition. Early diagnosis and intervention are the key steps in the management of this condition. We have reviewed our institution's 4-year data regarding the presentation and management of this condition. Methods: We conducted a prospective review of the records of 10 patients who presented to our institute from January 2018 to December 2021 with a splenic artery pseudoaneurysm. We found one patient with a true aneurysm, whom we excluded from the study. Results: This study included seven male and two female patients with a mean age of 47.7 years. Six patients presented to the emergency department with bleeding secondary to rupture aneurysm, which is the most common reason for admission. Pancreatitis was found to be the most common cause for splenic artery pseudoaneurysm (five patients). Computed tomography angiogram remained the modality of choice for diagnosing splenic artery pseudoaneurysm. All patients were successfully managed with endovascular intervention. Conclusion: Splenic artery pseudoaneurysm is usually a rare complication of pancreatitis, which is associated with high morbidity and mortality. Timely diagnosis and intervention are the keys to successful management. Endovascular embolization should be the first-line therapy in splenic artery pseudoaneurysm.

Autologous vein graft repair of mycotic innominate artery aneurysm: A case report.

INTRODUCTION: Innominate artery aneurysm (IAA) is an extremely rare fatal condition with an overall prevalence of less than 3 % of all supra-aortic artery aneurysms. These infrequent lesions usually present as an emergency and require challenging surgical procedures. CASE PRESENTATION: We report an interesting case of mycotic IAA in a 25 years old male patient. He was a known intravenous drug abuser having mycotic aneurysm arising from brachiocephalic artery with eccentric thrombus causing adjacent mass effect over the trachea. He underwent successful emergent surgical management of aneurysm with autologous vein graft using superficial femoral vein. Unfortunately, he died due to massive upper gastrointestinal bleeding leading to multi-organ failure after a prolonged post-operative course. CLINICAL DISCUSSION: Mycotic aneurysms of the IA are extremely rare with an overall incidence of 1-2.7 % cases of all IAA. Presentation of the IAA can be quite variable from asymptomatic to symptoms exhibiting mass effect over surrounding structures. Rupture of IAA can be fatal and can occur if not treated promptly. There are no current recommendations or guidelines for treatment and interventions in IAA. Surgical management involves complete excision of the aneurysm and then revascularization. CONCLUSION: Infected Innominate artery aneurysm is a rare surgical entity requiring early diagnosis, detailed investigation and prompt surgical management involving multidisciplinary team approach. Our case describes a relatively innovative approach to this scarce condition.

Role of simulation in open varicose veins surgery: A systematic review.

OBJECTIVE: To assess the types and effectiveness of simulators present for open varicose vein surgery. METHODS: The systematic review was conducted at The Aga Khan University Hospital Karachi and comprised studies published from 1st January 2000 to 30th June 2020 related to open varicose vein surgical procedures done on simulators. Databases searched were PubMed, Medline, Google Scholar, Cochrane and Scopus using appropriate key words. The primary outcome of the review was to assess the effectiveness of different types of simulators used for varicose vein surgery. RESULTS: Of the 286 articles found, 6(2%) were included. A variety of simulators ranging from animal models, homemade simulators and commercially designed models with high fidelity options had been used. Technical competence was the major domain assessed in most of the studies 5(83.3%), while 1(16.6%) study focussed on self-assessment. Blinding was done in 4(66.6%) studies for assessment purpose, and videorecording of the trainees' performance was done in 5(83.3%) studies. Most studies 4(66.6%) found the use of simulation to be an effective tool in achieving technical competence. CONCLUSION: The use of simulation in the training of surgical residents for open varicose vein surgery was found to be beneficial, but most studies were heterogeneous in terms of design, simulator types and study participants. This makes it difficult to establish the superiority of any one type of simulator over the rest. Further research is needed to develop and validate simulators in open varicose vein surgery procedures.

Role of Simulated Training for Carotid Endarterectomy: A Systematic Review.

Vascular surgery trainees often do not get to perform carotid endarterectomy (CEA) directly on the patients as it requires meticulous surgical technique and has a high risk of procedure-related complications. Hence, the role of simulation in training future vascular surgeons becomes essential. This review aims to assess the types and utility of simulators available for CEA. In this systematic review, all the studies performed on CEA simulation were included. The purpose of this review was to assess different types of simulators and their usefulness for CEA. We identified 122 articles, of which 10 were eligible for review. A variety of simulators, ranging from animal models, virtual reality simulators and commercially designed models with high fidelity options were used. Technical competence was the major domain assessed in the majority of the studies (n=8), whereas four studies evaluated anatomical and procedural knowledge. Blinding was done in five studies for assessment purposes. The majority of studies (n=9) found the simulation to be an effective tool for achieving technical competence. This review shows the potential usefulness of simulation in acquiring technical skills and procedural acumen for CEA. The available literature is unfortunately too diverse to have a common recommendation.

Hypoglossal Nerve Paraganglioma Depicting as Glomus Tumor of Neck.

INTRODUCTION: Paraganglioma are infrequent neuroendocrine tumors that are most commonly found in the carotid body, ganglia of the vagus, jugular and tympanic nerve. Very rarely they can involve other cranial nerves outside the cranial cavity, we present one such case of hypoglossal nerve paraganglioma in neck. CASE REPORT: A 48 years old male presented with 1-month history of right sided stroke and aphasia. Ultrasonography of neck revealed a highly vascular mass on the right side of the neck. CT angiogram confirmed a highly vascular mass arising above the carotid bifurcation. With the working diagnosis of Glomus tumor, he underwent right sided neck exploration, however, intra-operatively tumor was found to be arising from the hypoglossal nerve instead. Surgery was abandoned on basis of the available literature, with only 6 reported cases in the past 54 years. Patient had no immediate post op complications and was sent for cyber knife treatment. After completion of 5 cycles of cyber knife there was a total of 45% reduction in the size of the paraganglioma with the resolution of the patient's symptoms after a follow up of 6 months. CONCLUSION: Hypoglossal nerve paraganglioma is an uncommon tumor of the neck and can be misdiagnosed with the other tumors in this region especially chemodectoma and glomus tumor. The diagnostic criteria and appropriate treatment modalities have not been established due to the rare presentation hence hypoglossal paraganliomas should be kept in mind when Highly vascular neck mass is encountered.

Predictors of Poor Quality of Life after Primary Lower Limb Deep Venous Thrombosis: A Perspective from a Developing Nation.

Objective: We aimed to determine predictors of poor long term quality of life, using the VEINES Quality of Life (QOL) questionnaire, in patients with lower limb deep venous thrombosis (DVT). Material and Methods: This study included adult patients with primary lower limb DVT between January 2007 and December 2017. Post thrombotic syndrome (PTS) was assessed using the Villalta score and Quality of Life (QoL) by the VEINES quality of life questionnaire. Results: Our study included 125 patients, 57 (45.6%) of whom were males. The patient population's median age was 41 years (IQR: 34-47 years). The median follow up was 450 days (IQR: 390-1020 days). PTS occurred in 49 (39.2%) patients. Independent predictors of poor quality of life post DVT were progression to PTS, complete occlusion of vein, proximal (Ileofemoral) DVT, poor control of INR, poor compliance with compression stockings, severity of PTS, ileofemoral DVT and poor control of therapeutic anticoagulation. Conclusion: Predictors who are independently associated with poor quality of life post DVT are PTS, inability to maintain therapeutic anticoagulation and ileofemoral DVT.

Operative Techniques to Prevent Dialysis Access-associated Steal Syndrome in High-risk Patients Undergoing Surgery for Hemodialysis Access: A Systematic Review.

Up to 10% of patients suffer from various degrees of dialysis access-associated steal syndrome (DASS) after surgery for hemodialysis access. This systematic review was conducted to find out optimal intra-operative techniques to prevent DASS in high-risk patients. This systematic review is registered with PROSPERO (2017:CRD42017060804). It was conducted at Department of Surgery, Aga Khan University Hospital, Karachi. All types of studies conducted on intra-operative techniques to prevent DASS in high-risk population (Age > 60 years, female gender, diabetes mellitus, peripheral arterial disease and previous DASS) undergoing access creation from January 1990 till April 2019 were included in the systematic review. Thorough search was conducted on Pubmed, Google Scholar and Cochrane databases to identify relevant articles. Included studies reviewed for success of various techniques to prevent dialysis access steal syndrome are summarized. Out of 125 studies in the initial search, six met the inclusion criteria. Five were retrospective case series while one was a case report. The largest study sample size was 32. All but one study had arterio-venous access creation on an arm. "Proximalization of arterial inflow" was described in three and "prophylactic distal revascularization and interval ligation (DRIL) procedure" in two studies to prevent DASS. Only one patient out of these studies developed DASS at an overall follow-up of 7-42 months. Proximalization of inflow has been reported as the most common procedure performed to prevent DASS followed by extension technique and DRIL procedure. All three procedures have satisfactory outcome with no clear superiority of one over the other.

Template operative note, a better documentation.

Operative notes are a valuable part of patient's medical record, and carry the medico-legal significance. One way of improving it is to introduce the template form operative notes. Only few studies have been done worldwide to compare both the forms of operative notes. This cross-sectional study was conducted in the department of General Surgery, AKUH. This included the patients who underwent Laparoscopic cholecystectomy (Complying with inclusion criteria) from August 2013 till March 2014. Out of 24 patients, 19 were females. The completeness of data in template group was significantly better than traditional group (79.2% vs. 8.3%). There was no significant difference among the residents of different level (writing the notes) and the completeness of data in both the groups. Similarly the timing of day did not affect significantly on the completeness.

Why do patients with limb ischaemia present late to a vascular surgeon? A prospective cohort study from the developing world.

OBJECTIVE: To look into the factors responsible for delay in presentation of Iimb ischemia patients to a vascular surgeon. Methods: The prospective cohort study was conducted at the Aga Khan University Hospital, Karachi, from October 01, 2016, to August 10, 2018. Patients coming with delayed presentation of both acute and chronic limb ischemia were included. All the patients were assessed by qualified vascular surgeons. SPSS 23 was used for data analysis. Results: Of the 55 patients, 33(60%) had acute and 22(40%) had chronic limb ischaemia. Mean age of acute cases was 44±23.72 years and it was 60±12.49 years for chronic cases. Overall, the commonest reason behind delay was non-referral by primary physician which was the case with 11(33.3%) patients in the acute group, and 13(59%) in the chronic group. The limb loss in the acute group was 20(60%) and 8(36%) in the chronic group.. Conclusion: Delayed presentation of patients with limb ischaemia is mainly due to non-referral. A robust campaign needs to be launched to reduce the rate of limb loss.

Comparison of Upper Limb Translocated Femoral Vein and Prosthetic Arteriovenous Bridge Grafts.

Introduction Native veins are an ideal option for dialysis in a patient with chronic kidney disease (CKD) as compared to a prosthetic graft. Femoral vein (FV) translocation to the upper arm is also an alternative to a prosthetic graft as reported in the literature when all options of using the native veins of the arms are exhausted. Thus, we aimed to compare the patency of the upper limb translocated FV arteriovenous fistula (AVF) with a prosthetic arteriovenous bridge graft (AVBG). Methods It is a retrospective cohort study that was conducted in the Department of Vascular Surgery, Aga Khan University Hospital. It included adult patients who underwent either upper arm translocation of FV or prosthetic AVBG using the consecutive purposive sampling technique. There were a total of 10 patients who underwent FV translocation AVF and 20 patients who had AVBG in the upper arms. Results A total of 30 patients were included in the study. Of these 30 patients, 10 underwent FV translocation AVF and the remaining 20 had AVBG. There was a significant difference in the mean operating time of the two surgeries. The mean operating time in FV translocation was 223 (± 41.5) minutes and in those with AVBG, the mean operating time was 100 (±26.5) (p= <0.001). There was no significant difference in the total length of hospital stay in both procedures performed. The primary patency rate for FV translocation was 90% and 95% in AVBG (p=1.00). Ten percent of FV translocation had a primary failure rate compared with that of AVBG, which was 5% (p=1.00). The mean follow-up period was 61 weeks in the FV translocation group and 64 weeks in the AVG group. Conclusion There was no significant difference in both groups in terms of patency, length of hospital stay, and fewer complications were observed in the FV translocation group as compared with the AVBG group.

May-Thurner Syndrome: A Cause of Acute Left Iliac Vein Obstruction in Early Postpartum Period: A Case Report.

May-Thurner syndrome (MTS) is a rare disease common in middle aged females, characterised by left-sided lower limb Deep vein thrombosis (DVT) due to compression of the left iliac vein by the overriding right iliac artery. Pregnanc y and puerperal phases are one of the hypercoagulable states further predisposing towards th rombu s format io n. Treatme nt in c lu de s both conservative and interventional (venous thrombectomy with or without stenting). Here we report a case of a 34- year-old female in her early postpartum period who visited the Agha Khan University Hospital in July 2016, with the onset of acute pain and swelling in the left leg. Her workup revealed left-sided Acute DVT, secondary to MTS. Her case was su cces sfull y mana ged with conservative treatment. This case is an important addition to medical literature in the sense that DVT occurring on the onset of postpartum period should not always be attributed to the hypercoagulability, secondary to pregnancy. With early diagnosis and aggressive management, MT Scan be easily managed .

Multiple Skip Incisions Versus Single Long Incision for Single-stage Basilic Transposition Arteriovenous Fistula: A Cohort Study.

BACKGROUND: Basilic vein transposition via single long incision is a renowned technique despite its known wound-related complications. Contrary to that, multiple skip incisions technique is thought to have relatively lower wound-related complications. But to the best of our knowledge, these 2 techniques have never been formally compared. Therefore, we conducted this study to compare both. MATERIAL AND METHODS: This was a retrospective cohort study. Patients who underwent basilic vein transposition arteriovenous fistula (AVF) from January 2011 till May 2016 at Aga Khan University Hospital, Pakistan were eligible for inclusion in the study. Study population was divided into 2 groups; one group comprising of patients who underwent fistula formation through single long incision and the other group had the procedure carried out via multiple skip incisions. Wound-related complications including wound infection and dehiscence, fistula maturation time, duration of surgery, and primary patency at a follow-up of 12 months were recorded. RESULTS: Both the groups were comparable regarding baseline variables. Incidence proportion of wound infection, hematoma, and dehiscence was higher in long incision group; however, it was statistically insignificant. Primary patency at 12 months in skip versus long incision group was 73.0% vs. 69.7% (P-value: 0.62). The mean maturation time for fistula was 42.8 ± 9.5 days and 44.3 ± 10.4 days in skip and long incision group, respectively (P-value:0.31). Duration of surgery was comparable in both. CONCLUSIONS: Although skip technique does not have significant benefit over long incision technique based on these results, but it is a valid alternative. Randomized control trial is required to better differentiate between these two.

Fistulotomy versus fistulectomy for simple fistula in ano: a retrospective cohort study.

OBJECTIVE: To compare fistulotomy with fistulectomy for wound healing, duration of surgery, post-operative pain, incontinence and recurrence in patients with fistula in ano. METHODS: This retrospective cohort study was conducted at the Aga Khan University Hospital, Karachi, and comprised data of adults who had undergone fistulotomy/fistulectomy for simple fistula in ano from January 2007 to August 2012. Data collection was done in August 2013 using questionnaire and telephonic interviews. Outcome variables like duration of wound healing, recurrence, incontinence, duration of surgery and post-operative pain were compared in both the groups. SPSS 19 was used for data analysis. RESULTS: Of the 192 cases, there were 96(50%) in each group. The mean age was 40.51 years (range: 21-72 years) in the fistulotomy group and 41.14 years (range: 21-66 years) in the fistulectomy group (p=0.66). Both groups were comparable for baseline demographic variables. The median duration of wound healing was shorter in the fistulotomy group 15 days (Interquartile range: 7-20 days) compared to the fistulectomy group 30 days (Interquartile range: 15-42 days) (p<0.001). The incidence of recurrence was comparable in fistulotomy vs. fistulectomy (3[3.12%] vs. 4[4.16%]; p=0.70). The incidence of incontinence was higher in fistulotomy compared to fistulectomy (5[5.3%] vs. 12[12.5%]; p=0.07). The severity of incontinence was also compared but the difference was insignificant (p=0.06). The median duration of surgery was significantly shorter in fistulotomy group 17 minutes (Interquartile range: 12-25 minutes) compared to fistulectomy group 25 minutes Interquartile range: 20-35 minutes (p<0.001). The median post-operative pain in the surgical day care unit and at the first follow-up in clinic was zero for both groups. CONCLUSIONS: Fistulotomy yielded better results than fistulectomy since it significantly decreased the duration of wound healing and duration of surgery without increasing the incidence of recurrence, incontinence and post-operative pain.

Hookworm infestation as a cause of melena and severe anaemia in farmer.

Hookworm infections remain a major cause of morbidity in the developing world. Prevalence is highest in agricultural areas, where use of waste water for irrigation and poor hygiene increases infection rates among farmers. Infections present with gastrointestinal symptoms and chronic anaemia, and there are usually no signs of overt blood loss. The following report describes a case of melena in a middle-aged farmer, where the diagnosis of hookworm infestation was delayed due to the unusual presentation. The patient underwent multiple blood transfusions before referral to the Aga Khan University Hospital (AKUH), Karachi and was managed conservatively with mebendazole at our hospital after exclusion of other possible causes of gastrointestinal bleeding. This case highlights the importance of considering hookworm infestations as a cause of melena in the older age group, where other critical differentials such as peptic ulcer disease and occult malignancy may result in delay in initiation of treatment and a significant financial burden on the patient.

Prevention of contrast-induced acute kidney injury in patients with stable chronic renal disease undergoing elective percutaneous coronary and peripheral interventions: randomized comparison of two preventive strategies.

OBJECTIVE: We compared use of intravenous (IV) normal saline (NS) to sodium bicarbonate (NaHCO(3)) with or without oral N-acetylcysteine (NAC) for prevention of contrast-induced acute kidney injury (CI-AKI). BACKGROUND: CI-AKI is associated with significant adverse clinical events. Use of NAC has produced variable results. Recently, intravenous hydration with NaHCO(3) for CI-AKI prophylaxis has been adopted as standard treatment for patients with stable chronic renal disease undergoing catheterization procedures. METHODS: We prospectively enrolled 320 patients with baseline renal insufficiency scheduled to undergo catheterization. Patients were randomly assigned to receive either IV NS ± NAC (n = 161) or IV dextrose 5% in water containing 154 mEq/l of NaHCO(3) ± NAC (n = 159). IV NS was administered at 1 ml/kg body weight for 12 hr preprocedure and 12 more hr postprocedure. IV NaHCO(3) was administered at 3 ml/kg body weight for 1 hr preprocedure followed by 1 ml/kg body weight postprocedure. A 1,200 mg oral dose of NAC was given 2-12 hr preprocedure and 6-12 hr postprocedure in 50% of patients in each study arm. CI-AKI was defined as an increase of >0.5 mg/dl or >25% above baseline creatinine. RESULTS: Overall incidence of CI-AKI was 10.3%. There was no significant difference in incidence among the two groups (NS ± NAC 11.8% vs. NaHCO(3) ± NAC 8.8%, p = ns). Incidence of CI-AKI increased with increasing age (p = 0.001), contrast agent use >3 ml/kg body weight (p = 0.038) and diuretic use (p = 0.005). CONCLUSION: Incidence of CI-AKI was no different in the NaHCO(3) group compared to NS group, and NAC did not reduce CI-AKI in the two study arms.

Stent fracture, an incidental finding or a significant marker of clinical in-stent restenosis?

BACKGROUND: The predictors and clinical significance for stent fracture (SF) in drug-eluting stents (DES) remain unknown. We identified procedural factors leading to SF and its clinical consequences in DES. METHODS: Percutaneous coronary interventions were performed on 3,920 patients with DES over 12 months. In-stent restenosis (ISR) of DES was observed in 188 cases with 121 cases (64.4%) receiving a sirolimus-eluting stent (SES) and 67 (35.6%) a paclitaxol-eluting stent (PES). RESULTS: SF was identified in 35 (18.6%) of the 188 cases. The 35 cases were then compared with 153 cases of ISR without angiographic evidence of SF. SF was identified in 29 (23.9%) SES compared with 6 (9.0%) in PES (P < 0.05). With univariate analysis, additional factors associated with SF included longer mean stented segment length, male gender, overlapping stents, vessel segment angulation >75 degrees , and more stents (all P < 0.05). With multivariate adjustment, three factors, i.e., stenting on a bend >75 degrees (OR = 13.8, 95%CI 3.7 to 51; P < 0.001), SES (OR = 4.1, 95%CI 1.3 to 13.4; P < 0.018) and overlapping stented segments (OR = 3.9, 95%CI 1.1 to 14.1; P < 0.041) were statistically significant independent predictors of SF while larger stent diameter was protective (OR = 0.14, 95%CI 0.04 to 0.70; P < 0.017). CONCLUSION: SF proved to be associated with angiographically-documented clinical ISR. Although the exact mechanism is unknown, factors that appear to play a negative role in SF include vessel tortuosity, use of SES and overlapping stents. Larger stent diameter was protective. Further studies are needed to better define the factors important in the mechanism of SF.

Sudden cardiac death caused by migration of a TrapEase inferior vena cava filter: case report and review of the literature.

CASE: A 43-year-old female presented with sudden onset of palpitations, chest pain, and shortness of breath associated with hypoxemia. A helical computed tomography (CT) scan of the chest revealed a large saddle pulmonary embolism. Intravenous tPA relieved the shortness of breath and improved the hypoxemia. Inferior vena cava (IVC) filter (TrapEase, Cordis Corp., Miami, FL, USA) was placed. On day 6 of her hospitalization, she went into cardiopulmonary arrest while walking back from the rest room. The patient died despite a prolonged attempt at cardiopulmonary resuscitation. At that time, ventricular tachycardia and then ventricular fibrillation were recorded. Autopsy of the heart showed the IVC filter entrapped within the tricuspid valve. DISCUSSION: The incidence of IVC filter migration ranges from 0.3 to 6% with rare migration to the heart or lung (0.1-1.25%). Sudden cardiac death from migration of IVC filter is extremely rare. We report the first case of sudden cardiac death caused by migration of the TrapEase filter to the heart. There are two reports in the literature of death from migrating Greenfield and Antheor filters. CONCLUSION: An IVC filter migration to the heart, although rare, can cause serious arrhythmia and sudden cardiac death.

Hepatic artery stenosis after liver transplant, managed with percutaneous angioplasty and stent placement.

Hepatic artery stenosis is a recognized vascular complication of orthotopic liver transplant that carries significant morbidity and mortality. The authors present a case of hepatic artery stenosis in a 50-year-old female successfully treated with balloon angioplasty and stent. This case report highlights the importance of percutaneous intervention as a preferred treatment option in patients with hepatic artery stenosis post-orthotopic liver transplant.
