Vascular Specialist International.2014;30(1):38-42.

This is to report the technique of reversed iliac leg stent-graft in endovascular treatment for isolated internal iliac artery (IIA) aneurysm, which had significant size discrepancy between the common iliac artery (CIA) and external iliac artery (EIA) in 3 patients from different hospitals. Three patients were a 85- and two 82-year-old men. Treated were right IIA aneurysms, sized 6.5x6.2 cm, 5.0x4.0 cm, and 4.1 cm in longest diameter, respectively. The diameters of the right CIA and right EIA measured 21 mm/11 mm, 15 mm/11 mm, and 20 mm/10 mm, respectively. In all cases, reversed iliac leg stent-grafts were prepared on-site; unsheathed and mounted upside-down manually, and deployed in each right CIA. Post-stent-graft angiograms showed complete exclusion of the aneurysms, except for minimal type 1 endoleak in one case. This technique is a useful treatment option in patients with isolated IIA aneurysm.

Dae Woo YOO ; Myunghee YOON ; Hee Jae JUN

Vascular Specialist International.2014;30(1):33-37.

PURPOSE: Preservation of adequate vascular access is of vital importance for patients undergoing chronic dialysis in renal failure. The aim of this study is to evaluate the successful access rate and risk factors of arteriovenous fistula (AVF) in the arm for dialysis at a single center. MATERIALS AND METHODS: Patients undergoing vascular access operation between January 2006 and December 2011 were retrospectively identified. RESULTS: A total of 362 vascular access operations were performed. There were 338 autologous AVFs (93.4%) and 24 prosthetic grafts (6.6%). Men comprised 58.3% of all subjects. Mean age was 59.5+/-14.7 years. There were 187 diabetes mellitus patients (51.7%). There was a mean duration of 70.3+/-21.1 days between access creation to first cannulation. Overall successful access rate for dialysis was 95.9%. Of 338 autologous AVFs, 326 patients had patent AVFs for dialysis (96.4% surgical success rate), while 21 of 24 prosthetic grafts were patent (87.5% surgical success rate). A total of 141 patients (38.9%) came to surgery with preoperative central venous catheters (CVC) of which 130 (35.9%) AVFs had a patent fistula in the arm. The only risk factor related to successful access rate of AVF was preoperative CVC placement (P=0.012). CONCLUSION: Successful vascular access rate was 95.9%. The only risk factor related to patent access of AVF was preoperative CVC placement. At least 6 months prior to expected dialysis, AVF surgery is recommended, which may overcome the challenge of co-morbid conditions from having a preoperative CVC.

Tangential Resection of a Popliteal Vein Aneurysm in a Patient Complaining of Localized Popliteal Pain.

Sun HAN ; Jae Wook RYU

Vascular Specialist International.2016;32(1):33-36. doi:10.5758/vsi.2016.32.1.33

A 48-year old man presented with left popliteal pain. A 2.2×1.6 cm sized saccular aneurysm at the level of the left popliteal fossa was diagnosed by ultrasonography. Tangential aneurysmectomy and popliteal vein repair was performed uneventfully. The patient fared well for a year without symptoms. Popliteal vein aneurysms are rare and typically found in patients with fatal thromboembolic features without warning symptoms. Fortunately, our patient had localized pain which was helpful in its early diagnosis and treatment.

A 62-year-old male with a smoking history of 30 pack-years presented with a 1-year history of a periumbilical pulsating mass. He had been treated for hypertension for 2 years. Physical examination revealed a huge pulsating mass in the periumbilical abdomen. Femoral and popliteal arterial pulses were palpable. Computed tomography showed arterial dissection in the proximal segment of the superior mesenteric artery, a huge aneurysm (52×50 mm) with mural thrombus and two smaller aneurysms (20×20 mm) in the right ileocolic and ileal branches, along with atherosclerotic changes. Interposition using the great saphenous vein was performed after aneurysmal isolation and ligation of jejunal branches in the sac. Distal flow was reestablished by end-to-end and end-to-side anastomoses of the right ileocolic and ileal branches, respectively. No complications were observed at 1-year follow-up.

Vascular Specialist International.2016;32(1):26-28. doi:10.5758/vsi.2016.32.1.26

Endovascular aneurysm repair (EVAR) has been recommended as an alternative to open aneurysm repair. The risk of severe perioperative complications is lower than that in open surgical repair; however, late complications are more likely. After EVAR, regular yearly surveillance by duplex ultrasonography or computed tomography is recommended. We report the case of a 67-year-old man with a severely kinked left iliac branch of the stent graft 10 years after EVAR. He had not undergone regular follow-up during the last 4 years. We realigned the endograft kink by percutaneous transluminal angioplasty.

Rescue Therapy of Inadvertent Coil Migration for Endovascular Treatment of Type II Endoleak.

Kanghaeng LEE ; Hyung Sub PARK ; Taeseung LEE

Vascular Specialist International.2016;32(1):22-25. doi:10.5758/vsi.2016.32.1.22

Coil migration during endovascular procedures is not an unusual complication, but there is no standard management strategy for bailout. Here, we describe a technique for removal of a migrated coil using a snare. During embolization of type II endoleak from the inferior mesenteric artery in a post-endovascular aneurysm repair patient, the coil migrated to the sigmoidal artery causing an occlusion. We used a microsnare loop and successfully retrieved the migrated coil. This is the first case in Korea that uses a loop snare for the removal of a migrated coil during visceral endovascular treatment to our knowledge. This technique of using a microsnare for removal of displaced coils can be a good resort in selected cases.

Endovascular aneurysm repair has become the first-line treatment for abdominal aortic aneurysms and iliac artery aneurysms in recent years. However, the diameter of the infrarenal aorta is larger than that of the aortic bifurcation, especially with small aortic diameters, for which a reversed tapered device is necessary. We describe the off-label use of the upside-down Gore Excluder limb and double-barrel sandwich technique for the treatment of a penetrating abdominal aortic ulcer with a large common iliac artery aneurysm. These techniques offer an easy endovascular approach for excluding an aneurysm in selected patients. However, this technique is outside the standard instructions for use, therefore careful planning and long-term follow-up are mandatory.

Vascular Specialist International.2016;32(1):11-16. doi:10.5758/vsi.2016.32.1.11

PURPOSE: The purpose of this study was to review the natural history, clinical outcome and safety in patients undergoing sartorius muscle flap (SMF) for groin infection, including lymphocele. MATERIALS AND METHODS: We retrospectively reviewed the records of patients who underwent SMF in a single center between 2000 and 2009. RESULTS: Thirty patients (17 male, 13 female) underwent SMF for groin infection, which included infections of 22 artificial femoral bypass grafts (including 2 cryoveins) and 5 common femoral patch grafts, and 3 lymphocele infections (2 cardiac catheterizations and 1 penile cancer lymph node dissection). Wound isolates were most commonly Gram-positive organisms (n=22) with Gram-negative isolates and mixed infections accounting for 4 and 3 cases, respectively. In 9 patients there was no growth of organisms. Adjunctive wound vacuum-asssisted wound closure therapy was performed in 18 patients. Follow-up duration ranged from 8 days to 56 months (mean 14.1 months) after SMF. Reoperation was performed in 3 patients due to wound bleeding (n=1) and reinfection (n=1). One patient underwent graft excision with external bypass operation. There was 1 mortality case due to sepsis during the study period. CONCLUSION: We found that muscle flap surgery provides successful single-intervention therapy for groin infections including lymphocele. Graft ligation or aggressive excision with bypass surgery should be reserved for patients requiring rapid control of sepsis for lifesaving.

Role of Hyperhomocysteinemia and Methylene Tetrahydrofolate Reductase C677T Polymorphism in Idiopathic Portal Vein Thrombosis.

Habib GHAZNAVI ; Zahra SOHEILI ; Shahram SAMIEI ; Mohammad Soleiman SOLTANPOUR

Vascular Specialist International.2016;32(1):6-10. doi:10.5758/vsi.2016.32.1.6

PURPOSE: Portal vein thrombosis (PVT) is a rare and life-threatening vascular disorder characterized by obstruction or narrowing of the portal vein. Hyperhomocysteinemia and methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism has been studied in PVT patients with conflicting results. In the present study the association of hyperhomocysteinemia and MTHFR C677T polymorphism with PVT risk was investigated in Iranians. MATERIALS AND METHODS: Our study population consisted of 10 idiopathic PVT patients and 80 healthy control subjects matched for age and sex. MTHFR C677T polymorphism was genotyped by the polymerase chain reaction technique combined with restriction enzyme fragment length polymorphism (PCR-RFLP) technique and plasma total homocysteine (tHcy) levels were determined by enzyme immunoassay method. RESULTS: Mean plasma tHcy levels were significantly higher in PVT patients (20.2±6.8) than control subjects (10.9±4.7) (P=0.001). Moreover, plasma tHcy levels were significantly higher in 677T allele carriers relative to 677C allele carriers in both PVT patients (P=0.01) and control subjects (P=0.03). Neither homozygote nor heterozygote genotypes of MTHFR C677T polymorphism correlated significantly with PVT risk (P>0.05). Moreover, MTHFR C677T polymorphism didn't increase the risk of PVT under dominant (CT+TT vs. CC) or recessive (TT vs. CC+CT) genetic models analyzed (P>0.05). The difference in frequency of minor 677T allele between PVT patients and control subjects was not statistically significant (P>0.05). CONCLUSION: Based on the current study, we suggest that hyperhomocysteinemia constitutes a significant and common risk factor for PVT. Also, MTHFR C677T polymorphism is not a risk factor for PVT but is a contributing factor for elevated plasma tHcy levels.

Traumatic Carotid Artery Dissection: A Different Entity without Specific Guidelines.

George GALYFOS ; Konstantinos FILIS ; Fragiska SIGALA ; Argiri SIANOU

Vascular Specialist International.2016;32(1):1-5. doi:10.5758/vsi.2016.32.1.1

According to literature data, there are no distinct guidelines regarding the proper diagnostic and therapeutic management of traumatic carotid artery dissection (TCAD). Although most of cases evaluated in research studies refer to spontaneous carotid artery dissection, traumatic cases demand special considerations as far as diagnosis and treatment are concerned. Although both types of dissection share some common characteristics, a patient with TCAD usually presents with several concomitant injuries as well as a higher bleeding risk, thus complicating decision making in such patients. Therefore, aim of this review is to present available data regarding epidemiology, clinical presentation, diagnostics and treatment strategy in cases with TCAD in order to produce useful conclusions for everyday clinical practice.
