Pseudoaneurysm of abdominal aorta: a complication of intrahepatic arterial infusion therapy

Arterial perforation by an indwelling intrahepatic catheter for infusion chemotherapy occurred in a 69-year-old man with liver metastases from rectal cancer. Computed tomography demonstrated a pseudoaneurysm formation and was diagnostic of the complication.     

Pseudoaneurysm of the common femoral vein as a late complication of right heart catheterization

Complications following venous punctures are unusual. We describe a case of a false common femoral vein aneurysm following right heart catheterization in a patient with systemic venous hypertension due to tricuspid regurgitation. The initial interpretation of the Doppler ultrasound study lead to a digital subtraction femoral arteriogram which was normal. Magnetic resonance venography demonstrated a femoral venous pseudoaneurysm.     

Gallbladder necrosis after transcatheter hepatic arterial embolization: a technique to avoid this complication

We present a technique used to avoid unnecessary embolization of the cystic artery in the treatment of hepatoma by transcatheter arterial embolization. A special long tapering catheter that is flexible and soft enough to be inserted into the distal small branches of the heptic artery is used. Embolic material ( Oxycel , absorbable cellulose) was mixed with Mitocin -C (mitomycin) and contrast material. This mixture will help to avoid reflux.     

Pseudoaneurysm of the popliteal artery as a complication of an osteochondroma

This is a report of mechanical compression and transection of the popliteal artery by an osteochondroma, documented angiographically and pathologically, in a patient hospitalized for endocarditis.     

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa: a delayed complication of aortic root replacement

A 41-year-old male with prior history of aortic root replacement for infectious endocarditis was found to have a pseudoaneurysm in the fibrous continuity between the aortic and mitral valves: the so called "mitral-aortic intervalvular fibrosa." Preoperative cardiac-gated computed tomographic angiography and intraoperative transesophageal echocardiography imaging findings used to guide surgical repair are presented.     

Pseudoaneurysm and arteriovenous fistula after femoral artery catheterization: association with low femoral punctures

We determined the location of arterial injury in 11 patients who had pseudoaneurysms with (six cases) or without (five cases) arteriovenous fistula as a complication of cardiac catheterization. Medical records and arteriograms were examined retrospectively. Ten of the 11 pseudoaneurysms identified were located below the level of the femoral head. Five of six patients with arteriovenous fistula had simultaneous catheterization of both the femoral artery and the femoral vein. Although we did not determine the location of arterial puncture used in uncomplicated angiograms during the 5-year study period, our experience in 11 patients with pseudoaneurysms with or without arteriovenous fistula suggests that there is an association between a puncture site below the level of the femoral head and arterial injury. In addition, arteriovenous fistulas appear to be associated with simultaneous catheterization of the femoral artery and adjacent femoral vein.     

Fluoroscopic guidance in femoral artery puncture

Analysis of 100 femoral arteriograms demonstrated a consistent relationship between the course of the femoral artery and the femoral head. Fluoroscopic guidance can be of value in femoral puncture when the arterial pulse is diminished or obscured, for training purposes, and for analysis and correction of missed punctures.     

Percutaneous femoral artery puncture: practice and anatomy

In a survey of the superficial landmarks used to select the site of puncture of the femoral artery for angiography, the inguinal skin crease was most popular, preferred by 39.2% of angiographers. The maximal femoral pulse irrespective of the position of the skin crease was the next most popular landmark (24.7%). Bony landmarks were least popular (13.0%). The majority (73.7%) of those using the skin crease punctured at the same level or distal to it. The relationship of these superficial landmarks to the common femoral artery (CFA) and its bifurcation were investigated. The inguinal skin crease was distal to the bifurcation of the CFA in 71.9% of limbs (mean, 0.61 cm). The maximal femoral pulse was over the CFA in 92.7% of limbs, and the CFA was projected over the medial aspect of the femoral head in 77.9% of limbs. The use of the inguinal skin crease is a popular though unreliable guide for puncture of the CFA. Use of the maximal femoral pulse will enable more constant puncture of the CFA.     

Antegrade puncture of the femoral artery: morphologic study

To determine the optimal site for antegrade puncture of the femoral artery, the authors evaluated three cadaver specimens and computed tomographic (CT) scans of 50 patients. The relationships among the common femoral artery, the femoral artery bifurcation, the center of the femoral head, and the inguinal ligament were evaluated. CT showed that the center of the femoral head was always located caudal to the level of the inguinal ligament but cranial to the bifurcation of the common femoral artery. Therefore, the femoral head seems to provide a reliable landmark for entering the common femoral artery.     

Pseudoaneurysm and deep vein thrombosis complicating femoral osteochondroma: multimodality imaging

A case of a femoral osteochondroma complicated by pseudoaneurysm and deep venous thrombosis is presented. Multimodality imaging contributed crucial information to allow successful diagnosis and preoperative planning.     

Endovascular treatment of in-stent occlusion: new technique for recanalization of long superficial femoral artery occlusion (direct stent puncture technique)

In-stent reocclusion is a frequent complication of endovascular treatment and stenting, especially in the superficial femoral artery. Neointimal hyperplasia is the main cause of this problem, but in many cases, it occurs as a result of the presence of stent strut fractures. The two treatment options are endovascular and surgical intervention. The effectiveness of endovascular interventions in patients with critical limb ischemia has been well established, but in some cases, crossing the occluded stent is difficult. We describe a new technique to recanalize long in-stent superficial femoral artery occlusions characterized by direct stent puncture, followed by retrograde-antegrade recanalization after antegrade failures.

Single-wall puncture: a new technique for percutaneous transhepatic biliary drainage

OBJECTIVE: The purpose of our study is to evaluate the safety and utility of a new single-wall puncture technique for percutaneous transhepatic biliary drainage in comparison with the conventional double-wall puncture technique. CONCLUSION: Our results suggest that the single-wall puncture technique is a useful method for percutaneous transhepatic biliary drainage and may be safer than the conventional double-wall puncture technique.
